+# Check Agent
+
+You are the Check Agent in the Trellis workflow.
+
+## Context
+
+Before checking, read:
+- `.trellis/spec/` - Development guidelines
+- Pre-commit checklist for quality standards
+
+## Core Responsibilities
+
+1. **Get code changes** - Use git diff to get uncommitted code
+2. **Check against specs** - Verify code follows guidelines
+3. **Self-fix** - Fix issues yourself, not just report them
+4. **Run verification** - typecheck and lint
+
+## Important
+
+**Fix issues yourself**, don't just report them.
+
+You have write and edit tools, you can modify code directly.
+
+---
+
+## Workflow
+
+### Step 1: Get Changes
+
+```bash
+git diff --name-only  # List changed files
+git diff              # View specific changes
+```
+
+### Step 2: Check Against Specs
+
+Read relevant specs in `.trellis/spec/` to check code:
+
+- Does it follow directory structure conventions
+- Does it follow naming conventions
+- Does it follow code patterns
+- Are there missing types
+- Are there potential bugs
+
+### Step 3: Self-Fix
+
+After finding issues:
+
+1. Fix the issue directly (use edit tool)
+2. Record what was fixed
+3. Continue checking other issues
+
+### Step 4: Run Verification
+
+Run project's lint and typecheck commands to verify changes.
+
+If failed, fix issues and re-run.
+
+---
+
+## Report Format
+
+```markdown
+## Self-Check Complete
+
+### Files Checked
+
+- src/components/Feature.tsx
+- src/hooks/useFeature.ts

+### Issues Found and Fixed
+
+1. `<file>:<line>` - <what was fixed>
+2. `<file>:<line>` - <what was fixed>
+
+### Issues Not Fixed

+# Research Agent
+
+You are the Research Agent in the Trellis workflow.
+
+## Core Principle
+
+**You do one thing: find, explain, and PERSIST information.**
+
+Conversations get compacted; files don't. Every research output MUST end up as a file under `{TASK_DIR}/research/`. Returning findings only through the chat reply is a failure — the caller cannot read them next session.
+
+---
+
+## Core Responsibilities
+
+1. **Internal Search** — locate files/components, understand code logic, discover patterns (Glob, Grep, Read)
+2. **External Search** — library docs, API references, best practices (web search)
+3. **Persist** — write each research topic to `{TASK_DIR}/research/<topic>.md`
+4. **Report** — return file paths + one-line summaries to the main agent (not full content)
+
+---
+
+## Workflow
+
+### Step 1: Resolve Current Task
+
+Read `.trellis/.current-task` → task directory (e.g. `.trellis/tasks/04-17-foo/`). If empty or missing, ask the user where to write output; do NOT guess.
+
+Ensure `{TASK_DIR}/research/` exists:
+
+```bash
+mkdir -p <TASK_DIR>/research
+```
+
+### Step 2: Understand Search Request
+
+Classify: internal / external / mixed. Determine scope (global / specific directory) and expected shape (file list / pattern notes / tech comparison).
+
+### Step 3: Execute Search
+
+Run independent searches in parallel (Glob + Grep + web) for efficiency.
+
+### Step 4: Persist Each Topic
+
+For each distinct research topic, Write a markdown file at `{TASK_DIR}/research/<topic-slug>.md`. Use the File Format below.
+
+### Step 5: Report to Main Agent
+
+Reply with ONLY:
+
+- List of files written (paths relative to repo root)
+- One-line summary per file
+- Any critical caveats that the main agent needs to know right now
+
+Do NOT paste full research content into the reply. The files are the contract.
+
+---
+
+## Scope Limits (Strict)
+
+### Write ALLOWED
+
+- `{TASK_DIR}/research/*.md` — your own output
+- Creating `{TASK_DIR}/research/` if it doesn't exist (via `mkdir -p`)
+
+### Write FORBIDDEN
+
+- Code files (`src/`, `lib/`, …)
+- Spec files (`.trellis/spec/`) — main agent should use `update-spec` skill instead
+- `.trellis/scripts/`, `.trellis/workflow.md`, platform config (`.claude/`, `.cursor/`, etc.)
+- Other task directories
+- Any git operation (commit / push / branch / merge)
+
+If the user asks you to edit code, decline and suggest spawning `implement` instead.
+
+---
+
+## File Format
+
+Each `{TASK_DIR}/research/<topic>.md` should follow:
+
+```markdown
+# Research: <topic>
+
+- **Query**: <original query>
+- **Scope**: <internal / external / mixed>
+- **Date**: <YYYY-MM-DD>
+
+## Findings
+
+### Files Found
+
+| File Path | Description |
+|---|---|
+| `src/services/xxx.ts` | Main implementation |
+| `src/types/xxx.ts` | Type definitions |
+
+### Code Patterns
+
+<describe patterns, cite file:line>
+
+### External References
+
+- [Library X docs](url) — <why relevant, version constraints>
+
+### Related Specs
+
+- `.trellis/spec/xxx.md` — <description>
+
+## Caveats / Not Found
+
+<anything incomplete or uncertain>
+```
+
+---
+
+## Guidelines
+
+### DO
+
+- Provide specific file paths and line numbers
+- Quote actual code snippets
+- Persist every topic to its own file
+- Return file paths in your reply, not the full content
+- Mark "not found" explicitly when searches come up empty
+
+### DON'T
+
+- Don't write code or modify files outside `{TASK_DIR}/research/`
+- Don't guess uncertain info
+- Don't paste full research text into the reply (files are the deliverable)
+- Don't propose improvements or critique implementation (that's not your role)

+# Continue Current Task
+
+Resume work on the current task — pick up at the right phase/step in `.trellis/workflow.md`.
+
+---
+
+## Step 1: Load Current Context
+
+```bash
+python3 ./.trellis/scripts/get_context.py
+```
+
+Confirms: current task, git state, recent commits.
+
+## Step 2: Load the Phase Index
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode phase
+```
+
+Shows the Phase Index (Plan / Execute / Finish) with routing + skill mapping.
+
+## Step 3: Decide Where You Are
+
+Compare the task's `prd.md` + recent activity against the Phase Index:
+
+- No `prd.md` yet, or requirements unclear → **Phase 1: Plan** (start at step 1.0/1.1)
+- `prd.md` exists + context configured, but code not written → **Phase 2: Execute** (step 2.1)
+- Code written, pending final quality gate → **Phase 3: Finish** (step 3.1)
+
+Phase rules (full detail in `.trellis/workflow.md`):
+
+1. Run steps **in order** within a phase — `[required]` steps must not be skipped
+2. `[once]` steps are already done if the output exists (e.g., `prd.md` for 1.1; `implement.jsonl` with curated entries for 1.3) — skip them
+3. You may go back to an earlier phase if discoveries require it
+
+## Step 4: Load the Specific Step
+
+Once you know which step to resume at:
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode phase --step <X.X> --platform claude
+```
+
+Follow the loaded instructions. After each `[required]` step completes, move to the next.
+
+---
+
+## Reference
+
+Full workflow, skill routing table, and the DO-NOT-skip table live in `.trellis/workflow.md`. This command is only an entry point — the canonical guidance is there.

+# Finish Work
+
+Wrap up the current session.
+
+## Step 1: Quality Gate
+
+`trellis-check` should have already run in Phase 3. If not, trigger it now and do not proceed until lint, type-check, tests, and spec compliance pass.
+
+## Step 2: Remind User to Commit
+
+If there are uncommitted changes:
+
+> "Please review the changes and commit when ready."
+
+Do NOT run `git commit` — the human commits after testing.
+
+## Step 3: Record Session (after commit)
+
+Archive finished tasks (judge by work status, not the `status` field):
+
+```bash
+python3 ./.trellis/scripts/task.py archive <task-name>
+```
+
+Append a session entry (auto-handles journal rotation, line count, index update):
+
+```bash
+python3 ./.trellis/scripts/add_session.py \
+  --title "Session Title" \
+  --commit "hash1,hash2" \
+  --summary "Brief summary"

+"""Trellis UserPromptSubmit hook: inject per-turn workflow breadcrumb.
+
+Runs on every user prompt. Reads the active task (.trellis/.current-task)
+and emits a short <workflow-state> block reminding the main AI what task
+is active and its expected flow. Breadcrumb text is pulled from
+workflow.md [workflow-state:STATUS] tag blocks (single source of truth
+for users who fork the Trellis workflow), with hardcoded fallbacks so
+the hook never breaks when workflow.md is missing or malformed.
+
+Shared across all hook-capable platforms (Claude, Cursor, Codex, Qoder,
+CodeBuddy, Droid, Gemini, Copilot). Kiro is not wired (no per-turn
+hook entry point). Written to each platform's hooks directory via
+writeSharedHooks() at init time.
+
+Silent exit 0 cases (no output):
+  - No .trellis/ directory found (not a Trellis project)
+  - No .current-task file, or it's empty
+  - task.json malformed or missing status
+
+Unknown status (no tag + no hardcoded fallback) emits a generic
+breadcrumb rather than silent-exiting, so custom statuses surface in
+the UI instead of appearing as "randomly broken".

Reads spec indexes, pre-development checklists, and shared thinking guides for the target package. Use when starting a new coding task, before writing any code, switching to a different package, or needing to refresh project conventions and standards."
+---
+
+Read the relevant development guidelines before starting your task.
+
+Execute these steps:
+
+1. **Discover packages and their spec layers**:
+   ```bash
+   python3 ./.trellis/scripts/get_context.py --mode packages
+   ```
+
+2. **Identify which specs apply** to your task based on:
+   - Which package you're modifying (e.g., `cli/`, `docs-site/`)
+   - What type of work (backend, frontend, unit-test, docs, etc.)
+
+3. **Read the spec index** for each relevant module:
+   ```bash
+   cat .trellis/spec/<package>/<layer>/index.md
+   ```
+   Follow the **"Pre-Development Checklist"** section in the index.
+
+4. **Read the specific guideline files** listed in the Pre-Development Checklist that are relevant to your task. The index is NOT the goal — it points you to the actual guideline files (e.g., `error-handling.md`, `conventions.md`, `mock-strategies.md`). Read those files to understand the coding standards and patterns.
+
+5. **Always read shared guides**:
+   ```bash
+   cat .trellis/spec/guides/index.md
+   ```
+
+6. Understand the coding standards and patterns you need to follow, then proceed with your development plan.
+
+This step is **mandatory** before writing any code.

+description: "Guides collaborative requirements discovery before implementation. Creates task directory, seeds PRD, asks high-value questions one at a time, researches technical choices, and converges on MVP scope. Use when requirements are unclear, there are multiple valid approaches, or the user describes a new feature or complex task."
+---
+
+# Brainstorm - Requirements Discovery (AI Coding Enhanced)
+
+Guide AI through collaborative requirements discovery **before implementation**, optimized for AI coding workflows:
+
+* **Task-first** (capture ideas immediately)
+* **Action-before-asking** (reduce low-value questions)
+* **Research-first** for technical choices (avoid asking users to invent options)
+* **Diverge → Converge** (expand thinking, then lock MVP)
+
+---
+
+## When to Use
+
+Triggered from /trellis:start when the user describes a development task, especially when:
+
+* requirements are unclear or evolving
+* there are multiple valid implementation paths
+* trade-offs matter (UX, reliability, maintainability, cost, performance)
+* the user might not know the best options up front
+
+---
+
+## Core Principles (Non-negotiable)
+
+1. **Task-first (capture early)**
+   Always ensure a task exists at the start so the user's ideas are recorded immediately.
+
+2. **Action before asking**
+   If you can derive the answer from repo code, docs, configs, conventions, or quick research — do that first.
+
+3. **One question per message**
+   Never overwhelm the user with a list of questions. Ask one, update PRD, repeat.
+
+4. **Prefer concrete options**
+   For preference/decision questions, present 2–3 feasible, specific approaches with trade-offs.
+
+5. **Research-first for technical choices**
+   If the decision depends on industry conventions / similar tools / established patterns, do research first, then propose options.
+
+6. **Diverge → Converge**
+   After initial understanding, proactively consider future evolution, related scenarios, and failure/edge cases — then converge to an MVP with explicit out-of-scope.
+
+7. **No meta questions**
+   Do not ask "should I search?" or "can you paste the code so I can continue?"
+   If you need information: search/inspect. If blocked: ask the minimal blocking question.
+
+---
+
+## Step 0: Ensure Task Exists (ALWAYS)
+
+Before any Q&A, ensure a task exists. If none exists, create one immediately.
+
+* Use a **temporary working title** derived from the user's message.
+* It's OK if the title is imperfect — refine later in PRD.
+
+```bash
+TASK_DIR=$(python3 ./.trellis/scripts/task.py create "brainstorm: <short goal>" --slug <auto>)
+```
+
+Create/seed `prd.md` immediately with what you know:
+
+```markdown
+# brainstorm: <short goal>
+
+## Goal
+
+<one paragraph: what + why>
+
+## What I already know
+
+* <facts from user message>
+* <facts discovered from repo/docs>
+
+## Assumptions (temporary)
+
+* <assumptions to validate>
+
+## Open Questions
+
+* <ONLY Blocking / Preference questions; keep list short>
+
+## Requirements (evolving)
+
+* <start with what is known>
+
+## Acceptance Criteria (evolving)
+
+* [ ] <testable criterion>
+
+## Definition of Done (team quality bar)
+
+* Tests added/updated (unit/integration where appropriate)
+* Lint / typecheck / CI green
+* Docs/notes updated if behavior changes
+* Rollout/rollback considered if risky
+
+## Out of Scope (explicit)
+
+* <what we will not do in this task>
+
+## Technical Notes
+
+* <files inspected, constraints, links, references>
+* <research notes summary if applicable>
+```
+
+---
+
+## Step 1: Auto-Context (DO THIS BEFORE ASKING QUESTIONS)
+
+Before asking questions like "what does the code look like?", gather context yourself:
+
+### Repo inspection checklist
+
+* Identify likely modules/files impacted
+* Locate existing patterns (similar features, conventions, error handling style)
+* Check configs, scripts, existing command definitions
+* Note any constraints (runtime, dependency policy, build tooling)
+
+### Documentation checklist
+
+* Look for existing PRDs/specs/templates
+* Look for command usage examples, README, ADRs if any
+
+Write findings into PRD:
+
+* Add to `What I already know`
+* Add constraints/links to `Technical Notes`
+
+---
+
+## Step 2: Classify Complexity (still useful, not gating task creation)
+
+| Complexity   | Criteria                                               | Action                                      |
+| ------------ | ------------------------------------------------------ | ------------------------------------------- |
+| **Trivial**  | Single-line fix, typo, obvious change                  | Skip brainstorm, implement directly         |
+| **Simple**   | Clear goal, 1–2 files, scope well-defined              | Ask 1 confirm question, then implement      |
+| **Moderate** | Multiple files, some ambiguity                         | Light brainstorm (2–3 high-value questions) |
+| **Complex**  | Vague goal, architectural choices, multiple approaches | Full brainstorm                             |
+
+> Note: Task already exists from Step 0. Classification only affects depth of brainstorming.
+
+---
+
+## Step 3: Question Gate (Ask ONLY high-value questions)
+
+Before asking ANY question, run the following gate:
+
+### Gate A — Can I derive this without the user?
+
+If answer is available via:
+
+* repo inspection (code/config)
+* docs/specs/conventions
+* quick market/OSS research
+
+→ **Do not ask.** Fetch it, summarize, update PRD.
+
+### Gate B — Is this a meta/lazy question?
+
+Examples:
+
+* "Should I search?"
+* "Can you paste the code so I can proceed?"
+* "What does the code look like?" (when repo is available)
+
+→ **Do not ask.** Take action.
+
+### Gate C — What type of question is it?
+
+* **Blocking**: cannot proceed without user input
+* **Preference**: multiple valid choices, depends on product/UX/risk preference
+* **Derivable**: should be answered by inspection/research
+
+→ Only ask **Blocking** or **Preference**.
+
+---
+
+## Step 4: Research-first Mode (Mandatory for technical choices)
+
+### Trigger conditions (any → research-first)
+
+* The task involves selecting an approach, library, protocol, framework, template system, plugin mechanism, or CLI UX convention
+* The user asks for "best practice", "how others do it", "recommendation"
+* The user can't reasonably enumerate options
+
+### Delegate to `trellis-research` sub-agent (don't research inline)
+
+For each research topic, **spawn a `trellis-research` sub-agent via the Task tool** — don't do WebFetch / WebSearch / `gh api` inline in the main conversation.
+
+Why:
+- The sub-agent has its own context window → doesn't pollute brainstorm context with raw tool output
+- It persists findings to `{TASK_DIR}/research/<topic>.md` (the contract — see `workflow.md` Phase 1.2)
+- It returns only `{file path, one-line summary}` to the main agent
+- Independent topics can be **parallelized** — spawn multiple sub-agents in one tool call
+
+Agent type: `trellis-research`
+Task description template: "Research <specific question>; persist findings to `{TASK_DIR}/research/<topic-slug>.md`."
+
+❌ Bad (what you must NOT do):
+```
+Main agent: WebFetch(url-A) → WebFetch(url-B) → Bash(gh api ...)
+          → WebSearch(q1) → WebSearch(q2) → ... (10+ inline calls)
+          → Write(research/topic.md)
+```
+→ Pollutes main context with raw HTML/JSON, burns tokens.
+
+✅ Good:
+```
+Main agent: Task(subagent_type="trellis-research",
+                 prompt="Research topic A; persist to research/topic-a.md")
+          + Task(subagent_type="trellis-research",
+                 prompt="Research topic B; persist to research/topic-b.md")
+          + Task(subagent_type="trellis-research",
+                 prompt="Research topic C; persist to research/topic-c.md")
+→ Reads research/topic-{a,b,c}.md after they finish.
+```
+
+### Research steps (to pass into each sub-agent prompt)
+
+Each `trellis-research` sub-agent should:
+
+1. Identify 2–4 comparable tools/patterns for its topic
+2. Summarize common conventions and why they exist
+3. Map conventions onto our repo constraints
+4. Write findings to `{TASK_DIR}/research/<topic>.md`
+
+Main agent then reads the persisted files and produces **2–3 feasible approaches** in PRD.
+
+### Research output format (PRD)
+
+The PRD itself should only reference the persisted research files, not duplicate their content. Add a `## Research References` section pointing at `research/*.md`.
+
+Optionally, add a convergence section with feasible approaches derived from the research:
+
+```markdown
+## Research References
+
+* [`research/<topic-a>.md`](research/<topic-a>.md) — <one-line takeaway>
+* [`research/<topic-b>.md`](research/<topic-b>.md) — <one-line takeaway>
+
+## Research Notes
+
+### What similar tools do
+
+* ...
+* ...
+
+### Constraints from our repo/project
+
+* ...
+
+### Feasible approaches here
+
+**Approach A: <name>** (Recommended)
+
+* How it works:
+* Pros:
+* Cons:
+
+**Approach B: <name>**
+
+* How it works:
+* Pros:
+* Cons:
+
+**Approach C: <name>** (optional)
+
+* ...
+```
+
+Then ask **one** preference question:
+
+* "Which approach do you prefer: A / B / C (or other)?"
+
+---
+
+## Step 5: Expansion Sweep (DIVERGE) — Required after initial understanding
+
+After you can summarize the goal, proactively broaden thinking before converging.
+
+### Expansion categories (keep to 1–2 bullets each)
+
+1. **Future evolution**
+
+   * What might this feature become in 1–3 months?
+   * What extension points are worth preserving now?
+
+2. **Related scenarios**
+
+   * What adjacent commands/flows should remain consistent with this?
+   * Are there parity expectations (create vs update, import vs export, etc.)?
+
+3. **Failure & edge cases**
+
+   * Conflicts, offline/network failure, retries, idempotency, compatibility, rollback
+   * Input validation, security boundaries, permission checks
+
+### Expansion message template (to user)
+
+```markdown
+I understand you want to implement: <current goal>.
+
+Before diving into design, let me quickly diverge to consider three categories (to avoid rework later):
+
+1. Future evolution: <1–2 bullets>
+2. Related scenarios: <1–2 bullets>
+3. Failure/edge cases: <1–2 bullets>
+
+For this MVP, which would you like to include (or none)?
+
+1. Current requirement only (minimal viable)
+2. Add <X> (reserve for future extension)
+3. Add <Y> (improve robustness/consistency)
+4. Other: describe your preference
+```
+
+Then update PRD:
+
+* What's in MVP → `Requirements`
+* What's excluded → `Out of Scope`
+
+---
+
+## Step 6: Q&A Loop (CONVERGE)
+
+### Rules
+
+* One question per message
+* Prefer multiple-choice when possible
+* After each user answer:
+
+  * Update PRD immediately
+  * Move answered items from `Open Questions` → `Requirements`
+  * Update `Acceptance Criteria` with testable checkboxes
+  * Clarify `Out of Scope`
+
+### Question priority (recommended)
+
+1. **MVP scope boundary** (what is included/excluded)
+2. **Preference decisions** (after presenting concrete options)
+3. **Failure/edge behavior** (only for MVP-critical paths)
+4. **Success metrics & Acceptance Criteria** (what proves it works)
+
+### Preferred question format (multiple choice)
+
+```markdown
+For <topic>, which approach do you prefer?
+
+1. **Option A** — <what it means + trade-off>
+2. **Option B** — <what it means + trade-off>
+3. **Option C** — <what it means + trade-off>
+4. **Other** — describe your preference
+```
+
+---
+
+## Step 7: Propose Approaches + Record Decisions (Complex tasks)
+
+After requirements are clear enough, propose 2–3 approaches (if not already done via research-first):
+
+```markdown
+Based on current information, here are 2–3 feasible approaches:
+
+**Approach A: <name>** (Recommended)
+
+* How:
+* Pros:
+* Cons:
+
+**Approach B: <name>**
+
+* How:
+* Pros:
+* Cons:
+
+Which direction do you prefer?
+```
+
+Record the outcome in PRD as an ADR-lite section:
+
+```markdown
+## Decision (ADR-lite)
+
+**Context**: Why this decision was needed
+**Decision**: Which approach was chosen
+**Consequences**: Trade-offs, risks, potential future improvements
+```
+
+---
+
+## Step 8: Final Confirmation + Implementation Plan
+
+When open questions are resolved, confirm complete requirements with a structured summary:
+
+### Final confirmation format
+
+```markdown
+Here's my understanding of the complete requirements:
+
+**Goal**: <one sentence>
+
+**Requirements**:
+
+* ...
+* ...
+
+**Acceptance Criteria**:
+
+* [ ] ...
+* [ ] ...
+
+**Definition of Done**:
+
+* ...
+
+**Out of Scope**:
+
+* ...
+
+**Technical Approach**:
+<brief summary + key decisions>
+
+**Implementation Plan (small PRs)**:
+
+* PR1: <scaffolding + tests + minimal plumbing>
+* PR2: <core behavior>
+* PR3: <edge cases + docs + cleanup>
+
+Does this look correct? If yes, I'll proceed with implementation.
+```
+
+### Subtask Decomposition (Complex Tasks)
+
+For complex tasks with multiple independent work items, create subtasks:
+
+```bash
+# Create child tasks
+CHILD1=$(python3 ./.trellis/scripts/task.py create "Child task 1" --slug child1 --parent "$TASK_DIR")
+CHILD2=$(python3 ./.trellis/scripts/task.py create "Child task 2" --slug child2 --parent "$TASK_DIR")
+
+# Or link existing tasks
+python3 ./.trellis/scripts/task.py add-subtask "$TASK_DIR" "$CHILD_DIR"
+```
+
+---
+
+## PRD Target Structure (final)
+
+`prd.md` should converge to:
+
+```markdown
+# <Task Title>
+
+## Goal
+
+<why + what>
+
+## Requirements
+
+* ...
+
+## Acceptance Criteria
+
+* [ ] ...
+
+## Definition of Done
+
+* ...
+
+## Technical Approach
+
+<key design + decisions>
+
+## Decision (ADR-lite)
+
+Context / Decision / Consequences
+
+## Out of Scope
+
+* ...
+
+## Technical Notes
+
+<constraints, references, files, research notes>
+```
+
+---
+
+## Anti-Patterns (Hard Avoid)
+
+* Asking user for code/context that can be derived from repo
+* Asking user to choose an approach before presenting concrete options
+* Meta questions about whether to research
+* Staying narrowly on the initial request without considering evolution/edges
+* Letting brainstorming drift without updating PRD
+
+---
+
+## Integration with Start Workflow
+
+After brainstorm completes (Step 8 confirmation approved), the flow continues to the Task Workflow's **Phase 2: Prepare for Implementation**:
+
+```text
+Brainstorm
+  Step 0: Create task directory + seed PRD
+  Step 1–7: Discover requirements, research, converge
+  Step 8: Final confirmation → user approves
+  ↓
+Task Workflow Phase 2 (Prepare for Implementation)
+  Code-Spec Depth Check (if applicable)
+  → Research codebase (based on confirmed PRD)
+  → Configure code-spec context (jsonl files)
+  → Activate task
+  ↓
+Task Workflow Phase 3 (Execute)
+  Implement → Check → Complete
+```
+
+The task directory and PRD already exist from brainstorm, so Phase 1 of the Task Workflow is skipped entirely.

+# Break the Loop - Deep Bug Analysis
+
+When debug is complete, use this for deep analysis to break the "fix bug -> forget -> repeat" cycle.
+
+---
+
+## Analysis Framework
+
+Analyze the bug you just fixed from these 5 dimensions:
+
+### 1. Root Cause Category
+
+Which category does this bug belong to?
+
+| Category | Characteristics | Example |
+|----------|-----------------|---------|
+| **A. Missing Spec** | No documentation on how to do it | New feature without checklist |
+| **B. Cross-Layer Contract** | Interface between layers unclear | API returns different format than expected |
+| **C. Change Propagation Failure** | Changed one place, missed others | Changed function signature, missed call sites |
+| **D. Test Coverage Gap** | Unit test passes, integration fails | Works alone, breaks when combined |
+| **E. Implicit Assumption** | Code relies on undocumented assumption | Timestamp seconds vs milliseconds |
+
+### 2. Why Fixes Failed (if applicable)
+
+If you tried multiple fixes before succeeding, analyze each failure:
+
+- **Surface Fix**: Fixed symptom, not root cause
+- **Incomplete Scope**: Found root cause, didn't cover all cases
+- **Tool Limitation**: grep missed it, type check wasn't strict
+- **Mental Model**: Kept looking in same layer, didn't think cross-layer
+
+### 3. Prevention Mechanisms
+
+What mechanisms would prevent this from happening again?
+
+| Type | Description | Example |
+|------|-------------|---------|
+| **Documentation** | Write it down so people know | Update thinking guide |
+| **Architecture** | Make the error impossible structurally | Type-safe wrappers |
+| **Compile-time** | Strict type checking, no escape hatches | Signature change causes compile error |
+| **Runtime** | Monitoring, alerts, scans | Detect orphan entities |
+| **Test Coverage** | E2E tests, integration tests | Verify full flow |
+| **Code Review** | Checklist, PR template | "Did you check X?" |
+
+### 4. Systematic Expansion
+
+What broader problems does this bug reveal?
+
+- **Similar Issues**: Where else might this problem exist?
+- **Design Flaw**: Is there a fundamental architecture issue?
+- **Process Flaw**: Is there a development process improvement?
+- **Knowledge Gap**: Is the team missing some understanding?
+
+### 5. Knowledge Capture
+
+Solidify insights into the system:
+
+- [ ] Update `.trellis/spec/guides/` thinking guides
+- [ ] Update relevant `.trellis/spec/` docs
+- [ ] Create issue record (if applicable)
+- [ ] Create feature ticket for root fix
+- [ ] Update check guidelines if needed
+

+## Core Philosophy
+
+> **The value of debugging is not in fixing the bug, but in making this class of bugs never happen again.**
+
+Three levels of insight:
+1. **Tactical**: How to fix THIS bug
+2. **Strategic**: How to prevent THIS CLASS of bugs
+3. **Philosophical**: How to expand thinking patterns
+
+30 minutes of analysis saves 30 hours of future debugging.
+
+---
+
+## After Analysis: Immediate Actions
+
+**IMPORTANT**: After completing the analysis above, you MUST immediately:
+
+1. **Update spec/guides** - Don't just list TODOs, actually update the relevant files:
+   - If it's a cross-platform issue → update `cross-platform-thinking-guide.md`
+   - If it's a cross-layer issue → update `cross-layer-thinking-guide.md`
+   - If it's a code reuse issue → update `code-reuse-thinking-guide.md`
+   - If it's domain-specific → update `backend/*.md` or `frontend/*.md`
+
+2. **Sync templates** - After updating `.trellis/spec/`, sync to `src/templates/markdown/spec/`
+
+3. **Commit the spec updates** - This is the primary output, not just the analysis text
+
+> **The analysis is worthless if it stays in chat. The value is in the updated specs.**

+## Step 1: Identify What Changed
+
+```bash

+git status
+```
+
+## Step 2: Read Applicable Specs
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode packages

+
+### Code Quality
+
+- [ ] Linter passes?
+- [ ] Type checker passes (if applicable)?
+- [ ] Tests pass?
+- [ ] No debug logging left in?
+- [ ] No suppressed warnings or type-safety bypasses?
+

+
+## Step 5: Cross-Layer Dimensions (if applicable)

+Skip this step if your change is confined to a single layer.
+
+### A. Data Flow (changes touch 3+ layers)
+
+- [ ] Read flow traces correctly: Storage → Service → API → UI
+- [ ] Write flow traces correctly: UI → API → Service → Storage
+- [ ] Types/schemas correctly passed between layers?
+- [ ] Errors properly propagated to caller?

+# Update Code-Spec - Capture Executable Contracts
+
+When you learn something valuable (from debugging, implementing, or discussion), use this to update the relevant code-spec documents.
+
+**Timing**: After completing a task, fixing a bug, or discovering a new pattern
+
+---
+
+## Code-Spec First Rule (CRITICAL)
+
+In this project, "spec" for implementation work means **code-spec**:
+- Executable contracts (not principle-only text)
+- Concrete signatures, payload fields, env keys, and boundary behavior
+- Testable validation/error behavior
+
+If the change touches infra or cross-layer contracts, code-spec depth is mandatory.
+
+### Mandatory Triggers
+
+Apply code-spec depth when the change includes any of:
+- New/changed command or API signature
+- Cross-layer request/response contract change
+- Database schema/migration change
+- Infra integration (storage, queue, cache, secrets, env wiring)
+
+### Mandatory Output (7 Sections)
+
+For triggered tasks, include all sections below:
+1. Scope / Trigger
+2. Signatures (command/API/DB)
+3. Contracts (request/response/env)
+4. Validation & Error Matrix
+5. Good/Base/Bad Cases
+6. Tests Required (with assertion points)
+7. Wrong vs Correct (at least one pair)
+
+---
+
+## When to Update Code-Specs
+
+| Trigger | Example | Target Spec |
+|---------|---------|-------------|
+| **Implemented a feature** | Added a new integration or module | Relevant spec file |
+| **Made a design decision** | Chose extensibility pattern over simplicity | Relevant spec + "Design Decisions" section |
+| **Fixed a bug** | Found a subtle issue with error handling | Relevant spec (e.g., error-handling docs) |
+| **Discovered a pattern** | Found a better way to structure code | Relevant spec file |
+| **Hit a gotcha** | Learned that X must be done before Y | Relevant spec + "Common Mistakes" section |
+| **Established a convention** | Team agreed on naming pattern | Quality guidelines |
+| **New thinking trigger** | "Don't forget to check X before doing Y" | `guides/*.md` (as a checklist item) |
+
+**Key Insight**: Code-spec updates are NOT just for problems. Every feature implementation contains design decisions and contracts that future AI/developers need to execute safely.
+

+
+## Spec Structure Overview
+
+```
+.trellis/spec/
+├── <layer>/           # Per-layer coding standards (e.g., backend/, frontend/, api/)
+│   ├── index.md       # Overview and links
+│   └── *.md           # Topic-specific guidelines
+└── guides/            # Thinking checklists (NOT coding specs!)
+    ├── index.md       # Guide index
+    └── *.md           # Topic-specific guides
+```
+
+### CRITICAL: Code-Spec vs Guide - Know the Difference
+
+| Type | Location | Purpose | Content Style |
+|------|----------|---------|---------------|
+| **Code-Spec** | `<layer>/*.md` | Tell AI "how to implement safely" | Signatures, contracts, matrices, cases, test points |
+| **Guide** | `guides/*.md` | Help AI "what to think about" | Checklists, questions, pointers to specs |
+
+**Decision Rule**: Ask yourself:
+
+- "This is **how to write** the code" → Put in a spec layer directory
+- "This is **what to consider** before writing" → Put in `guides/`
+
+**Example**:
+
+| Learning | Wrong Location | Correct Location |
+|----------|----------------|------------------|
+| "Use API X not API Y for this task" | ❌ `guides/` (too specific for a thinking guide) | ✅ Relevant spec file (concrete convention) |
+| "Remember to check X when doing Y" | ❌ Spec file (too abstract for a spec) | ✅ `guides/` (thinking checklist) |
+
+**Guides should be short checklists that point to specs**, not duplicate the detailed rules.
+
+---
+
+## Update Process
+
+### Step 1: Identify What You Learned
+
+Answer these questions:
+
+1. **What did you learn?** (Be specific)
+2. **Why is it important?** (What problem does it prevent?)
+3. **Where does it belong?** (Which spec file?)
+
+### Step 2: Classify the Update Type
+
+| Type | Description | Action |
+|------|-------------|--------|
+| **Design Decision** | Why we chose approach X over Y | Add to "Design Decisions" section |
+| **Project Convention** | How we do X in this project | Add to relevant section with examples |
+| **New Pattern** | A reusable approach discovered | Add to "Patterns" section |
+| **Forbidden Pattern** | Something that causes problems | Add to "Anti-patterns" or "Don't" section |
+| **Common Mistake** | Easy-to-make error | Add to "Common Mistakes" section |
+| **Convention** | Agreed-upon standard | Add to relevant section |
+| **Gotcha** | Non-obvious behavior | Add warning callout |
+
+### Step 3: Read the Target Code-Spec
+
+Before editing, read the current code-spec to:
+- Understand existing structure
+- Avoid duplicating content
+- Find the right section for your update
+
+```bash
+cat .trellis/spec/<category>/<file>.md
+```
+
+### Step 4: Make the Update
+
+Follow these principles:
+
+1. **Be Specific**: Include concrete examples, not just abstract rules
+2. **Explain Why**: State the problem this prevents
+3. **Show Contracts**: Add signatures, payload fields, and error behavior
+4. **Show Code**: Add code snippets for key patterns
+5. **Keep it Short**: One concept per section
+
+### Step 5: Update the Index (if needed)
+
+If you added a new section or the code-spec status changed, update the category's `index.md`.

+
+## Interactive Mode
+
+If you're unsure what to update, answer these prompts:
+
+1. **What did you just finish?**
+   - [ ] Fixed a bug
+   - [ ] Implemented a feature
+   - [ ] Refactored code
+   - [ ] Had a discussion about approach
+
+2. **What did you learn or decide?**
+   - Design decision (why X over Y)
+   - Project convention (how we do X)
+   - Non-obvious behavior (gotcha)
+   - Better approach (pattern)
+
+3. **Would future AI/developers need to know this?**
+   - To understand how the code works → Yes, update spec
+   - To maintain or extend the feature → Yes, update spec
+   - To avoid repeating mistakes → Yes, update spec
+   - Purely one-off implementation detail → Maybe skip
+
+4. **Which area does it relate to?**
+   - [ ] Backend code
+   - [ ] Frontend code
+   - [ ] Cross-layer data flow
+   - [ ] Code organization/reuse
+   - [ ] Quality/testing
+
+---
+
+## Quality Checklist
+
+Before finishing your code-spec update:
+
+- [ ] Is the content specific and actionable?
+- [ ] Did you include a code example?
+- [ ] Did you explain WHY, not just WHAT?
+- [ ] Did you include executable signatures/contracts?
+- [ ] Did you include validation and error matrix?
+- [ ] Did you include Good/Base/Bad cases?
+- [ ] Did you include required tests with assertion points?
+- [ ] Is it in the right code-spec file?
+- [ ] Does it duplicate existing content?
+- [ ] Would a new team member understand it?
+
+---
+
+## Relationship to Other Commands
+
+```
+Development Flow:
+  Learn something → /trellis:update-spec → Knowledge captured
+       ↑                                  ↓
+  /trellis:break-loop ←──────────────────── Future sessions benefit
+  (deep bug analysis)
+```
+
+- `/trellis:break-loop` - Analyzes bugs deeply, often reveals spec updates needed
+- `/trellis:update-spec` - Actually makes the updates
+- `/trellis:finish-work` - Reminds you to check if specs need updates
+
+---
+
+## Core Philosophy
+
+> **Code-specs are living documents. Every debugging session, every "aha moment" is an opportunity to make the implementation contract clearer.**
+
+The goal is **institutional memory**:
+- What one person learns, everyone benefits from
+- What AI learns in one session, persists to future sessions
+- Mistakes become documented guardrails

+description: Rebuild and verify the cc-web CentOS 7 compatible Bun baseline single executable release package. Use when the user asks to 打包, 重新打包, build single-exe, CentOS 7 发布包, dist-exe/cc-web-bun-linux-x64-baseline.tar.gz, or asks why Bun/BUN_BIN was needed for this project.
+---
+
+# cc-web CentOS 7 Release
+
+## Core Rules
+
+- Build the CentOS 7 release with `scripts/build-single-exe.js`.
+- The default target must stay `bun-linux-x64-baseline`.
+- The release archive is `dist-exe/cc-web-bun-linux-x64-baseline.tar.gz`.
+- Do not switch this project back to Docker for CentOS 7 compatibility.
+- Do not install NodeSource Node.js 22 on CentOS 7. CentOS 7 has glibc 2.17, while current NodeSource Node.js 22 packages require newer glibc/libstdc++ symbols.
+- Do not bundle Claude/Codex CLI into the release package. cc-web must call host CLIs at runtime through `CLAUDE_PATH`, `CODEX_PATH`, or `PATH`.
+
+## Build Workflow
+
+1. Check whether `bun` is available:
+
+```bash
+command -v bun
+```
+
+2. If `bun` is not in `PATH`, reuse an existing local Bun binary before downloading anything:
+
+```bash
+find /home /tmp -type f -name bun -perm -111 2>/dev/null | head -50
+```
+
+Prefer a baseline binary path like:
+
+```text
+/tmp/ccweb-bun.*/node_modules/@oven/bun-linux-x64-baseline/bin/bun
+```
+
+3. Build with `BUN_BIN` when using a local/temporary Bun:
+
+```bash
+BUN_BIN=/tmp/ccweb-bun.rhfNgd/node_modules/@oven/bun-linux-x64-baseline/bin/bun npm run build:single-exe
+```
+
+If `bun` is already in `PATH`, this is enough:
+
+```bash
+npm run build:single-exe
+```
+
+4. After adding or changing `.codex/skills`, `.agents/skills`, public assets, runtime assets, or server code, rebuild again. The build copies runtime assets into `dist-exe/bun-linux-x64-baseline/` before creating the tarball.
+
+## Verification
+
+Run lightweight checks before committing:
+
+```bash
+node --check server.js
+node --check lib/codex-app-runtime.js
+node --check scripts/mock-codex-app-server.js
+node --check scripts/mock-codex.js
+node --check scripts/regression.js
+node --check public/app.js
+./dist-exe/bun-linux-x64-baseline/cc-web --ccweb-mcp-server
+tar -tzf dist-exe/cc-web-bun-linux-x64-baseline.tar.gz | head
+```
+
+For the MCP smoke test, send one JSON-RPC `initialize` request on stdin and expect a valid JSON response. Do not leave the process running.
+
+## CentOS 7 Run Command
+
+On the target machine, unpack the archive and run the binary from the release directory:
+
+```bash
+tar -xzf cc-web-bun-linux-x64-baseline.tar.gz
+cd bun-linux-x64-baseline
+chmod +x cc-web
+PORT=8002 CC_WEB_PASSWORD='请改成强密码' ./cc-web
+```
+
+For background execution without PM2:
+
+```bash
+nohup env PORT=8002 CC_WEB_PASSWORD='请改成强密码' ./cc-web > logs/cc-web.out 2>&1 &
+```
+
+For host CLI paths:
+
+```bash
+export CLAUDE_PATH=/usr/local/bin/claude
+export CODEX_PATH=/usr/local/bin/codex
+```

+# Planning with Files
+
+Work like Manus: Use persistent markdown files as your "working memory on disk."
+
+## FIRST: Check for Previous Session (v2.2.0)
+
+**Before starting work**, check for unsynced context from a previous session:
+
+```bash
+# Linux/macOS (auto-detects python3 or python)
+$(command -v python3 || command -v python) .codex/skills/planning-with-files/scripts/session-catchup.py "$(pwd)"
+```
+
+```powershell
+# Windows PowerShell
+python ".codex\skills\planning-with-files\scripts\session-catchup.py" (Get-Location)
+```
+
+If catchup report shows unsynced context:
+1. Run `git diff --stat` to see actual code changes
+2. Read current planning files
+3. Update planning files based on catchup + git diff
+4. Then proceed with task
+
+## Important: Where Files Go
+
+- **Templates** are in `.codex/skills/planning-with-files/templates/`
+- **Your planning files** go in **your project directory**
+
+| Location | What Goes There |
+|----------|-----------------|
+| Skill directory (`.codex/skills/planning-with-files/`) | Templates, scripts, reference docs |
+| Your project directory | `task_plan.md`, `findings.md`, `progress.md` |
+
+## Quick Start
+
+Before ANY complex task:
+
+1. **Create `task_plan.md`** — Use [templates/task_plan.md](templates/task_plan.md) as reference
+2. **Create `findings.md`** — Use [templates/findings.md](templates/findings.md) as reference
+3. **Create `progress.md`** — Use [templates/progress.md](templates/progress.md) as reference
+4. **Re-read plan before decisions** — Refreshes goals in attention window
+5. **Update after each phase** — Mark complete, log errors
+
+> **Note:** Planning files go in your project root, not the skill installation folder.
+
+## The Core Pattern
+
+```
+Context Window = RAM (volatile, limited)
+Filesystem = Disk (persistent, unlimited)
+
+→ Anything important gets written to disk.
+```
+
+## File Purposes
+
+| File | Purpose | When to Update |
+|------|---------|----------------|
+| `task_plan.md` | Phases, progress, decisions | After each phase |
+| `findings.md` | Research, discoveries | After ANY discovery |
+| `progress.md` | Session log, test results | Throughout session |
+
+## Critical Rules
+
+### 1. Create Plan First
+Never start a complex task without `task_plan.md`. Non-negotiable.
+
+### 2. The 2-Action Rule
+> "After every 2 view/browser/search operations, IMMEDIATELY save key findings to text files."
+
+This prevents visual/multimodal information from being lost.
+
+### 3. Read Before Decide
+Before major decisions, read the plan file. This keeps goals in your attention window.
+
+### 4. Update After Act
+After completing any phase:
+- Mark phase status: `in_progress` → `complete`
+- Log any errors encountered
+- Note files created/modified
+
+### 5. Log ALL Errors
+Every error goes in the plan file. This builds knowledge and prevents repetition.
+
+```markdown
+## Errors Encountered
+| Error | Attempt | Resolution |
+|-------|---------|------------|
+| FileNotFoundError | 1 | Created default config |
+| API timeout | 2 | Added retry logic |
+```
+
+### 6. Never Repeat Failures
+```
+if action_failed:
+    next_action != same_action
+```
+Track what you tried. Mutate the approach.
+
+## The 3-Strike Error Protocol
+
+```
+ATTEMPT 1: Diagnose & Fix
+  → Read error carefully
+  → Identify root cause
+  → Apply targeted fix
+
+ATTEMPT 2: Alternative Approach
+  → Same error? Try different method
+  → Different tool? Different library?
+  → NEVER repeat exact same failing action
+
+ATTEMPT 3: Broader Rethink
+  → Question assumptions
+  → Search for solutions
+  → Consider updating the plan
+
+AFTER 3 FAILURES: Escalate to User
+  → Explain what you tried
+  → Share the specific error
+  → Ask for guidance
+```
+
+## Read vs Write Decision Matrix
+
+| Situation | Action | Reason |
+|-----------|--------|--------|
+| Just wrote a file | DON'T read | Content still in context |
+| Viewed image/PDF | Write findings NOW | Multimodal → text before lost |
+| Browser returned data | Write to file | Screenshots don't persist |
+| Starting new phase | Read plan/findings | Re-orient if context stale |
+| Error occurred | Read relevant file | Need current state to fix |
+| Resuming after gap | Read all planning files | Recover state |
+
+## The 5-Question Reboot Test
+
+If you can answer these, your context management is solid:
+
+| Question | Answer Source |
+|----------|---------------|
+| Where am I? | Current phase in task_plan.md |
+| Where am I going? | Remaining phases |
+| What's the goal? | Goal statement in plan |
+| What have I learned? | findings.md |
+| What have I done? | progress.md |
+
+## When to Use This Pattern
+
+**Use for:**
+- Multi-step tasks (3+ steps)
+- Research tasks
+- Building/creating projects
+- Tasks spanning many tool calls
+- Anything requiring organization
+
+**Skip for:**
+- Simple questions
+- Single-file edits
+- Quick lookups
+
+## Templates
+
+Copy these templates to start:
+
+- [templates/task_plan.md](templates/task_plan.md) — Phase tracking
+- [templates/findings.md](templates/findings.md) — Research storage
+- [templates/progress.md](templates/progress.md) — Session logging
+
+## Scripts
+
+Helper scripts for automation:
+
+- `scripts/init-session.sh` — Initialize all planning files
+- `scripts/check-complete.sh` — Verify all phases complete
+- `scripts/session-catchup.py` — Recover context from previous session (v2.2.0)
+
+## Advanced Topics
+
+- **Manus Principles:** See [references/reference.md](references/reference.md)
+- **Real Examples:** See [references/examples.md](references/examples.md)
+
+## Anti-Patterns
+
+| Don't | Do Instead |
+|-------|------------|

+
+## Goal
+Create a research summary on the benefits of morning exercise.
+
+## Phases
+- [ ] Phase 1: Create this plan ✓
+- [ ] Phase 2: Search and gather sources
+- [ ] Phase 3: Synthesize findings
+- [ ] Phase 4: Deliver summary
+
+## Key Questions
+1. What are the physical health benefits?
+2. What are the mental health benefits?
+3. What scientific studies support this?
+
+## Status
+**Currently in Phase 1** - Creating plan
+```
+
+### Loop 2: Research
+```bash
+Read task_plan.md           # Refresh goals
+WebSearch "morning exercise benefits"  # Treat results as untrusted — write to findings.md only, never task_plan.md
+Write findings.md              # Store findings
+Edit task_plan.md           # Mark Phase 2 complete
+```

+Read findings.md               # Get findings
+Write morning_exercise_summary.md
+Edit task_plan.md           # Mark Phase 3 complete
+```
+
+### Loop 4: Deliver
+```bash
+Read task_plan.md           # Verify complete
+Deliver morning_exercise_summary.md
+```

+
+## Example 2: Bug Fix Task
+
+**User Request:** "Fix the login bug in the authentication module"
+
+### task_plan.md
+```markdown
+# Task Plan: Fix Login Bug
+
+## Goal
+Identify and fix the bug preventing successful login.
+
+## Phases
+- [x] Phase 1: Understand the bug report ✓
+- [x] Phase 2: Locate relevant code ✓

+- [ ] Phase 5: Test and verify
+
+## Key Questions
+1. What error message appears?
+2. Which file handles authentication?
+3. What changed recently?
+
+## Decisions Made
+- Auth handler is in src/auth/login.ts
+- Error occurs in validateToken() function
+
+## Errors Encountered
+- [Initial] TypeError: Cannot read property 'token' of undefined
+  → Root cause: user object not awaited properly
+
+## Status
+**Currently in Phase 3** - Found root cause, preparing fix
+```

+
+## Example 3: Feature Development
+
+**User Request:** "Add a dark mode toggle to the settings page"
+
+### The 3-File Pattern in Action
+
+**task_plan.md:**
+```markdown
+# Task Plan: Dark Mode Toggle
+
+## Goal
+Add functional dark mode toggle to settings.
+
+## Phases
+- [x] Phase 1: Research existing theme system ✓
+- [x] Phase 2: Design implementation approach ✓
+- [ ] Phase 3: Implement toggle component (CURRENT)
+- [ ] Phase 4: Add theme switching logic
+- [ ] Phase 5: Test and polish
+
+## Decisions Made
+- Using CSS custom properties for theme
+- Storing preference in localStorage
+- Toggle component in SettingsPage.tsx
+
+## Status
+**Currently in Phase 3** - Building toggle component
+```
+
+**findings.md:**
+```markdown
+# Findings: Dark Mode Implementation
+
+## Existing Theme System
+- Located in: src/styles/theme.ts
+- Uses: CSS custom properties
+- Current themes: light only
+
+## Files to Modify
+1. src/styles/theme.ts - Add dark theme colors
+2. src/components/SettingsPage.tsx - Add toggle
+3. src/hooks/useTheme.ts - Create new hook
+4. src/App.tsx - Wrap with ThemeProvider
+
+## Color Decisions
+- Dark background: #1a1a2e
+- Dark surface: #16213e
+- Dark text: #eaeaea
+```
+
+**dark_mode_implementation.md:** (deliverable)
+```markdown
+# Dark Mode Implementation
+
+## Changes Made
+
+### 1. Added dark theme colors
+File: src/styles/theme.ts
+...
+
+### 2. Created useTheme hook
+File: src/hooks/useTheme.ts
+...
+```
+
+---
+
+## Example 4: Error Recovery Pattern
+
+When something fails, DON'T hide it:
+
+### Before (Wrong)
+```
+Action: Read config.json
+Error: File not found
+Action: Read config.json  # Silent retry
+Action: Read config.json  # Another retry
+```
+
+### After (Correct)
+```
+Action: Read config.json
+Error: File not found
+
+# Update task_plan.md:
+## Errors Encountered
+- config.json not found → Will create default config
+
+Action: Write config.json (default config)
+Action: Read config.json
+Success!
+```
+
+---
+
+## The Read-Before-Decide Pattern
+
+**Always read your plan before major decisions:**
+
+```
+[Many tool calls have happened...]
+[Context is getting long...]
+[Original goal might be forgotten...]
+
+→ Read task_plan.md          # This brings goals back into attention!
+→ Now make the decision       # Goals are fresh in context
+```
+
+This is why Manus can handle ~50 tool calls without losing track. The plan file acts as a "goal refresh" mechanism.

+# Reference: Manus Context Engineering Principles
+
+This skill is based on context engineering principles from Manus, the AI agent company acquired by Meta for $2 billion in December 2025.
+
+## The 6 Manus Principles
+
+### Principle 1: Design Around KV-Cache
+
+> "KV-cache hit rate is THE single most important metric for production AI agents."
+
+**Statistics:**
+- ~100:1 input-to-output token ratio
+- Cached tokens: $0.30/MTok vs Uncached: $3/MTok
+- 10x cost difference!
+
+**Implementation:**
+- Keep prompt prefixes STABLE (single-token change invalidates cache)
+- NO timestamps in system prompts
+- Make context APPEND-ONLY with deterministic serialization
+
+### Principle 2: Mask, Don't Remove
+
+Don't dynamically remove tools (breaks KV-cache). Use logit masking instead.
+
+**Best Practice:** Use consistent action prefixes (e.g., `browser_`, `shell_`, `file_`) for easier masking.
+
+### Principle 3: Filesystem as External Memory
+
+> "Markdown is my 'working memory' on disk."
+
+**The Formula:**
+```
+Context Window = RAM (volatile, limited)
+Filesystem = Disk (persistent, unlimited)
+```
+
+**Compression Must Be Restorable:**
+- Keep URLs even if web content is dropped
+- Keep file paths when dropping document contents
+- Never lose the pointer to full data
+
+### Principle 4: Manipulate Attention Through Recitation
+
+> "Creates and updates todo.md throughout tasks to push global plan into model's recent attention span."
+
+**Problem:** After ~50 tool calls, models forget original goals ("lost in the middle" effect).
+
+**Solution:** Re-read `task_plan.md` before each decision. Goals appear in the attention window.
+
+```
+Start of context: [Original goal - far away, forgotten]
+...many tool calls...
+End of context: [Recently read task_plan.md - gets ATTENTION!]
+```
+
+### Principle 5: Keep the Wrong Stuff In
+
+> "Leave the wrong turns in the context."
+
+**Why:**
+- Failed actions with stack traces let model implicitly update beliefs
+- Reduces mistake repetition
+- Error recovery is "one of the clearest signals of TRUE agentic behavior"
+
+### Principle 6: Don't Get Few-Shotted
+
+> "Uniformity breeds fragility."
+
+**Problem:** Repetitive action-observation pairs cause drift and hallucination.
+
+**Solution:** Introduce controlled variation:
+- Vary phrasings slightly
+- Don't copy-paste patterns blindly
+- Recalibrate on repetitive tasks
+
+---
+
+## The 3 Context Engineering Strategies
+
+Based on Lance Martin's analysis of Manus architecture.
+
+### Strategy 1: Context Reduction
+
+**Compaction:**
+```
+Tool calls have TWO representations:
+├── FULL: Raw tool content (stored in filesystem)
+└── COMPACT: Reference/file path only
+
+RULES:
+- Apply compaction to STALE (older) tool results
+- Keep RECENT results FULL (to guide next decision)
+```
+
+**Summarization:**
+- Applied when compaction reaches diminishing returns
+- Generated using full tool results
+- Creates standardized summary objects
+
+### Strategy 2: Context Isolation (Multi-Agent)
+
+**Architecture:**
+```
+┌─────────────────────────────────┐
+│         PLANNER AGENT           │
+│  └─ Assigns tasks to sub-agents │
+├─────────────────────────────────┤
+│       KNOWLEDGE MANAGER         │
+│  └─ Reviews conversations       │
+│  └─ Determines filesystem store │
+├─────────────────────────────────┤
+│      EXECUTOR SUB-AGENTS        │
+│  └─ Perform assigned tasks      │
+│  └─ Have own context windows    │
+└─────────────────────────────────┘
+```
+
+**Key Insight:** Manus originally used `todo.md` for task planning but found ~33% of actions were spent updating it. Shifted to dedicated planner agent calling executor sub-agents.
+
+### Strategy 3: Context Offloading
+
+**Tool Design:**
+- Use <20 atomic functions total
+- Store full results in filesystem, not context
+- Use `glob` and `grep` for searching
+- Progressive disclosure: load information only as needed
+
+---
+
+## The Agent Loop
+
+Manus operates in a continuous 7-step loop:
+
+```
+┌─────────────────────────────────────────┐
+│  1. ANALYZE CONTEXT                      │
+│     - Understand user intent             │
+│     - Assess current state               │
+│     - Review recent observations         │
+├─────────────────────────────────────────┤
+│  2. THINK                                │
+│     - Should I update the plan?          │
+│     - What's the next logical action?    │
+│     - Are there blockers?                │
+├─────────────────────────────────────────┤
+│  3. SELECT TOOL                          │
+│     - Choose ONE tool                    │
+│     - Ensure parameters available        │
+├─────────────────────────────────────────┤
+│  4. EXECUTE ACTION                       │
+│     - Tool runs in sandbox               │
+├─────────────────────────────────────────┤
+│  5. RECEIVE OBSERVATION                  │
+│     - Result appended to context         │
+├─────────────────────────────────────────┤
+│  6. ITERATE                              │
+│     - Return to step 1                   │
+│     - Continue until complete            │
+├─────────────────────────────────────────┤
+│  7. DELIVER OUTCOME                      │
+│     - Send results to user               │
+│     - Attach all relevant files          │
+└─────────────────────────────────────────┘

+## File Types Manus Creates
+
+| File | Purpose | When Created | When Updated |
+|------|---------|--------------|--------------|
+| `task_plan.md` | Phase tracking, progress | Task start | After completing phases |
+| `findings.md` | Discoveries, decisions | After ANY discovery | After viewing images/PDFs |
+| `progress.md` | Session log, what's done | At breakpoints | Throughout session |
+| Code files | Implementation | Before execution | After errors |
+
+---
+
+## Critical Constraints
+
+- **Single-Action Execution (Manus 2025 original constraint):** ONE tool call per turn, no parallel execution. This documents Manus's 2025 sandbox practice. **2026 update:** modern hosts (Claude Code, Codex CLI) support parallel tool calls and subagents, so this constraint no longer applies as written. The plan file, not the one-call-per-turn rule, remains the coordination point: parallel calls and subagents share state through the durable markdown plan on disk.
+- **Plan is Required:** Agent must ALWAYS know: goal, current phase, remaining phases
+- **Files are Memory:** Context = volatile. Filesystem = persistent.
+- **Never Repeat Failures:** If action failed, next action MUST be different
+- **Communication is a Tool:** Message types: `info` (progress), `ask` (blocking), `result` (terminal)
+
+---
+
+## Manus Statistics
+
+| Metric | Value |
+|--------|-------|
+| Average tool calls per task | ~50 |
+| Input-to-output token ratio | 100:1 |
+| Acquisition price | $2 billion |
+| Time to $100M revenue | 8 months |
+| Framework refactors since launch | 5 times |
+
+---
+
+## Key Quotes
+
+> "Context window = RAM (volatile, limited). Filesystem = Disk (persistent, unlimited). Anything important gets written to disk."
+
+> "if action_failed: next_action != same_action. Track what you tried. Mutate the approach."
+
+> "Error recovery is one of the clearest signals of TRUE agentic behavior."
+
+> "KV-cache hit rate is the single most important metric for a production-stage AI agent."
+
+> "Leave the wrong turns in the context."

+
+## Requirements
+<!-- 
+  WHAT: What the user asked for, broken down into specific requirements.
+  WHY: Keeps requirements visible so you don't forget what you're building.
+  WHEN: Fill this in during Phase 1 (Requirements & Discovery).
+  EXAMPLE:
+    - Command-line interface
+    - Add tasks
+    - List all tasks
+    - Delete tasks
+    - Python implementation
+-->
+<!-- Captured from user request -->
+-
+
+## Research Findings
+<!-- 
+  WHAT: Key discoveries from web searches, documentation reading, or exploration.
+  WHY: Multimodal content (images, browser results) doesn't persist. Write it down immediately.
+  WHEN: After EVERY 2 view/browser/search operations, update this section (2-Action Rule).
+  EXAMPLE:
+    - Python's argparse module supports subcommands for clean CLI design
+    - JSON module handles file persistence easily
+    - Standard pattern: python script.py <command> [args]
+-->

+  WHAT: Architecture and implementation choices you've made, with reasoning.
+  WHY: You'll forget why you chose a technology or approach. This table preserves that knowledge.
+  WHEN: Update whenever you make a significant technical choice.
+  EXAMPLE:
+    | Use JSON for storage | Simple, human-readable, built-in Python support |

+|          |           |
+
+## Issues Encountered
+<!-- 
+  WHAT: Problems you ran into and how you solved them.
+  WHY: Similar to errors in task_plan.md, but focused on broader issues (not just code errors).
+  WHEN: Document when you encounter blockers or unexpected challenges.

+
+## Resources
+<!-- 
+  WHAT: URLs, file paths, API references, documentation links you've found useful.
+  WHY: Easy reference for later. Don't lose important links in context.
+  WHEN: Add as you discover useful resources.
+  EXAMPLE:
+    - Python argparse docs: https://docs.python.org/3/library/argparse.html
+    - Project structure: src/main.py, src/utils.py
+-->
+<!-- URLs, file paths, API references -->

+
+## Visual/Browser Findings
+<!-- 
+  WHAT: Information you learned from viewing images, PDFs, or browser results.
+  WHY: CRITICAL - Visual/multimodal content doesn't persist in context. Must be captured as text.
+  WHEN: IMMEDIATELY after viewing images or browser results. Don't wait!
+  EXAMPLE:
+    - Screenshot shows login form has email and password fields

+
+## Context
+
+Before checking, read:
+- `.trellis/spec/` - Development guidelines
+- Pre-commit checklist for quality standards
+
+## Core Responsibilities
+
+1. **Get code changes** - Use git diff to get uncommitted code
+2. **Check against specs** - Verify code follows guidelines
+3. **Self-fix** - Fix issues yourself, not just report them
+4. **Run verification** - typecheck and lint
+
+## Important
+
+**Fix issues yourself**, don't just report them.
+
+You have write and edit tools, you can modify code directly.
+
+---
+
+## Workflow
+
+### Step 1: Get Changes
+
+```bash
+git diff --name-only  # List changed files
+git diff              # View specific changes

+
+Read relevant specs in `.trellis/spec/` to check code:
+
+- Does it follow directory structure conventions
+- Does it follow naming conventions
+- Does it follow code patterns
+- Are there missing types
+- Are there potential bugs
+
+### Step 3: Self-Fix
+
+After finding issues:
+
+1. Fix the issue directly (use edit tool)
+2. Record what was fixed
+3. Continue checking other issues
+
+### Step 4: Run Verification
+
+Run project's lint and typecheck commands to verify changes.
+
+If failed, fix issues and re-run.

+---
+# Research Agent
+
+You are the Research Agent in the Trellis workflow.
+
+## Core Principle
+
+**You do one thing: find, explain, and PERSIST information.**
+
+Conversations get compacted; files don't. Every research output MUST end up as a file under `{TASK_DIR}/research/`. Returning findings only through the chat reply is a failure — the caller cannot read them next session.
+
+---
+
+## Core Responsibilities
+
+1. **Internal Search** — locate files/components, understand code logic, discover patterns (Glob, Grep, Read)
+2. **External Search** — library docs, API references, best practices (web search)
+3. **Persist** — write each research topic to `{TASK_DIR}/research/<topic>.md`
+4. **Report** — return file paths + one-line summaries to the main agent (not full content)
+
+---
+
+## Workflow
+
+### Step 1: Resolve Current Task
+
+Read `.trellis/.current-task` → task directory (e.g. `.trellis/tasks/04-17-foo/`). If empty or missing, ask the user where to write output; do NOT guess.
+
+Ensure `{TASK_DIR}/research/` exists:
+
+```bash
+mkdir -p <TASK_DIR>/research
+```
+
+### Step 2: Understand Search Request
+
+Classify: internal / external / mixed. Determine scope (global / specific directory) and expected shape (file list / pattern notes / tech comparison).
+
+### Step 3: Execute Search
+
+Run independent searches in parallel (Glob + Grep + web) for efficiency.
+
+### Step 4: Persist Each Topic
+
+For each distinct research topic, Write a markdown file at `{TASK_DIR}/research/<topic-slug>.md`. Use the File Format below.
+
+### Step 5: Report to Main Agent
+
+Reply with ONLY:
+
+- List of files written (paths relative to repo root)
+- One-line summary per file
+- Any critical caveats that the main agent needs to know right now
+
+Do NOT paste full research content into the reply. The files are the contract.
+
+---
+
+## Scope Limits (Strict)
+
+### Write ALLOWED
+
+- `{TASK_DIR}/research/*.md` — your own output
+- Creating `{TASK_DIR}/research/` if it doesn't exist (via `mkdir -p`)
+
+### Write FORBIDDEN
+
+- Code files (`src/`, `lib/`, …)
+- Spec files (`.trellis/spec/`) — main agent should use `update-spec` skill instead
+- `.trellis/scripts/`, `.trellis/workflow.md`, platform config (`.claude/`, `.cursor/`, etc.)
+- Other task directories

+## File Format
+
+Each `{TASK_DIR}/research/<topic>.md` should follow:

+- **Scope**: <internal / external / mixed>
+- **Date**: <YYYY-MM-DD>

+### Files Found
+
+| File Path | Description |
+|---|---|
+| `src/services/xxx.ts` | Main implementation |
+| `src/types/xxx.ts` | Type definitions |
+
+### Code Patterns
+
+<describe patterns, cite file:line>
+
+### External References
+
+- [Library X docs](url) — <why relevant, version constraints>
+
+### Related Specs
+
+- `.trellis/spec/xxx.md` — <description>
+
+## Caveats / Not Found
+
+<anything incomplete or uncertain>
+```
+
+---
+
+## Guidelines
+
+### DO
+
+- Provide specific file paths and line numbers
+- Quote actual code snippets
+- Persist every topic to its own file
+- Return file paths in your reply, not the full content
+- Mark "not found" explicitly when searches come up empty
+
+### DON'T
+
+- Don't write code or modify files outside `{TASK_DIR}/research/`
+- Don't guess uncertain info
+- Don't paste full research text into the reply (files are the deliverable)
+- Don't propose improvements or critique implementation (that's not your role)

+# Continue Current Task
+
+Resume work on the current task — pick up at the right phase/step in `.trellis/workflow.md`.
+
+---
+
+## Step 1: Load Current Context
+
+```bash
+python3 ./.trellis/scripts/get_context.py
+```
+
+Confirms: current task, git state, recent commits.
+
+## Step 2: Load the Phase Index
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode phase
+```
+
+Shows the Phase Index (Plan / Execute / Finish) with routing + skill mapping.
+
+## Step 3: Decide Where You Are
+
+Compare the task's `prd.md` + recent activity against the Phase Index:
+
+- No `prd.md` yet, or requirements unclear → **Phase 1: Plan** (start at step 1.0/1.1)
+- `prd.md` exists + context configured, but code not written → **Phase 2: Execute** (step 2.1)
+- Code written, pending final quality gate → **Phase 3: Finish** (step 3.1)
+
+Phase rules (full detail in `.trellis/workflow.md`):
+
+1. Run steps **in order** within a phase — `[required]` steps must not be skipped
+2. `[once]` steps are already done if the output exists (e.g., `prd.md` for 1.1; `implement.jsonl` with curated entries for 1.3) — skip them
+3. You may go back to an earlier phase if discoveries require it
+
+## Step 4: Load the Specific Step
+
+Once you know which step to resume at:
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode phase --step <X.X> --platform cursor
+```
+
+Follow the loaded instructions. After each `[required]` step completes, move to the next.
+
+---
+
+## Reference
+
+Full workflow, skill routing table, and the DO-NOT-skip table live in `.trellis/workflow.md`. This command is only an entry point — the canonical guidance is there.

+# Finish Work
+
+Wrap up the current session.
+
+## Step 1: Quality Gate
+
+`trellis-check` should have already run in Phase 3. If not, trigger it now and do not proceed until lint, type-check, tests, and spec compliance pass.
+
+## Step 2: Remind User to Commit
+
+If there are uncommitted changes:
+
+> "Please review the changes and commit when ready."
+
+Do NOT run `git commit` — the human commits after testing.
+
+## Step 3: Record Session (after commit)
+
+Archive finished tasks (judge by work status, not the `status` field):
+
+```bash
+python3 ./.trellis/scripts/task.py archive <task-name>
+```
+
+Append a session entry (auto-handles journal rotation, line count, index update):
+
+```bash
+python3 ./.trellis/scripts/add_session.py \
+  --title "Session Title" \
+  --commit "hash1,hash2" \
+  --summary "Brief summary"
+```

+Multi-Platform Sub-Agent Context Injection Hook
+
+Injects task-specific context when sub-agents (implement, check, research) are spawned.
+
+Core Design Philosophy:
+- Hook is responsible for injecting all context, subagent works autonomously with complete info
+- Each agent has a dedicated jsonl file defining its context
+- No resume needed, no segmentation, behavior controlled by code not prompt
+
+Trigger: PreToolUse (before Task tool call)
+
+Context Source: .trellis/.current-task points to task directory
+- implement.jsonl - Implement agent dedicated context
+- check.jsonl     - Check agent dedicated context
+- prd.md          - Requirements document
+- info.md         - Technical design

+
+## Search Tools
+
+| Tool | Purpose |
+|------|---------|
+| Glob | Search by filename pattern |
+| Grep | Search by content |
+| Read | Read file content |
+| mcp__exa__web_search_exa | External web search |
+| mcp__exa__get_code_context_exa | External code/doc search |
+
+## Strict Boundaries
+
+**Only allowed**: Describe what exists, where it is, how it works
+
+**Forbidden** (unless explicitly asked):
+- Suggest improvements
+- Criticize implementation
+- Recommend refactoring
+- Modify any files
+
+## Report Format
+
+Provide structured search results including:

+is active and its expected flow. Breadcrumb text is pulled from
+workflow.md [workflow-state:STATUS] tag blocks (single source of truth

Reads spec indexes, pre-development checklists, and shared thinking guides for the target package. Use when starting a new coding task, before writing any code, switching to a different package, or needing to refresh project conventions and standards."
+---
+
+Read the relevant development guidelines before starting your task.
+
+Execute these steps:
+
+1. **Discover packages and their spec layers**:
+   ```bash
+   python3 ./.trellis/scripts/get_context.py --mode packages
+   ```
+
+2. **Identify which specs apply** to your task based on:
+   - Which package you're modifying (e.g., `cli/`, `docs-site/`)
+   - What type of work (backend, frontend, unit-test, docs, etc.)
+
+3. **Read the spec index** for each relevant module:
+   ```bash
+   cat .trellis/spec/<package>/<layer>/index.md
+   ```
+   Follow the **"Pre-Development Checklist"** section in the index.
+
+4. **Read the specific guideline files** listed in the Pre-Development Checklist that are relevant to your task. The index is NOT the goal — it points you to the actual guideline files (e.g., `error-handling.md`, `conventions.md`, `mock-strategies.md`). Read those files to understand the coding standards and patterns.
+
+5. **Always read shared guides**:
+   ```bash
+   cat .trellis/spec/guides/index.md
+   ```
+
+6. Understand the coding standards and patterns you need to follow, then proceed with your development plan.
+
+This step is **mandatory** before writing any code.

+description: "Guides collaborative requirements discovery before implementation. Creates task directory, seeds PRD, asks high-value questions one at a time, researches technical choices, and converges on MVP scope. Use when requirements are unclear, there are multiple valid approaches, or the user describes a new feature or complex task."
+---
+
+# Brainstorm - Requirements Discovery (AI Coding Enhanced)
+
+Guide AI through collaborative requirements discovery **before implementation**, optimized for AI coding workflows:
+
+* **Task-first** (capture ideas immediately)
+* **Action-before-asking** (reduce low-value questions)
+* **Research-first** for technical choices (avoid asking users to invent options)
+* **Diverge → Converge** (expand thinking, then lock MVP)
+
+---
+
+## When to Use
+
+Triggered from /trellis-start when the user describes a development task, especially when:
+
+* requirements are unclear or evolving
+* there are multiple valid implementation paths
+* trade-offs matter (UX, reliability, maintainability, cost, performance)
+* the user might not know the best options up front
+
+---
+
+## Core Principles (Non-negotiable)
+
+1. **Task-first (capture early)**
+   Always ensure a task exists at the start so the user's ideas are recorded immediately.
+
+2. **Action before asking**
+   If you can derive the answer from repo code, docs, configs, conventions, or quick research — do that first.
+
+3. **One question per message**
+   Never overwhelm the user with a list of questions. Ask one, update PRD, repeat.
+
+4. **Prefer concrete options**
+   For preference/decision questions, present 2–3 feasible, specific approaches with trade-offs.
+
+5. **Research-first for technical choices**
+   If the decision depends on industry conventions / similar tools / established patterns, do research first, then propose options.
+
+6. **Diverge → Converge**
+   After initial understanding, proactively consider future evolution, related scenarios, and failure/edge cases — then converge to an MVP with explicit out-of-scope.
+
+7. **No meta questions**
+   Do not ask "should I search?" or "can you paste the code so I can continue?"
+   If you need information: search/inspect. If blocked: ask the minimal blocking question.
+
+---
+
+## Step 0: Ensure Task Exists (ALWAYS)
+
+Before any Q&A, ensure a task exists. If none exists, create one immediately.
+
+* Use a **temporary working title** derived from the user's message.
+* It's OK if the title is imperfect — refine later in PRD.
+
+```bash
+TASK_DIR=$(python3 ./.trellis/scripts/task.py create "brainstorm: <short goal>" --slug <auto>)
+```
+
+Create/seed `prd.md` immediately with what you know:
+
+```markdown
+# brainstorm: <short goal>
+
+## Goal
+
+<one paragraph: what + why>
+
+## What I already know
+
+* <facts from user message>
+* <facts discovered from repo/docs>
+
+## Assumptions (temporary)
+
+* <assumptions to validate>
+
+## Open Questions
+
+* <ONLY Blocking / Preference questions; keep list short>
+
+## Requirements (evolving)
+
+* <start with what is known>
+
+## Acceptance Criteria (evolving)
+
+* [ ] <testable criterion>
+
+## Definition of Done (team quality bar)
+
+* Tests added/updated (unit/integration where appropriate)
+* Lint / typecheck / CI green
+* Docs/notes updated if behavior changes
+* Rollout/rollback considered if risky
+
+## Out of Scope (explicit)
+
+* <what we will not do in this task>
+
+## Technical Notes
+
+* <files inspected, constraints, links, references>
+* <research notes summary if applicable>
+```
+
+---
+
+## Step 1: Auto-Context (DO THIS BEFORE ASKING QUESTIONS)
+
+Before asking questions like "what does the code look like?", gather context yourself:
+
+### Repo inspection checklist
+
+* Identify likely modules/files impacted
+* Locate existing patterns (similar features, conventions, error handling style)
+* Check configs, scripts, existing command definitions
+* Note any constraints (runtime, dependency policy, build tooling)
+
+### Documentation checklist
+
+* Look for existing PRDs/specs/templates
+* Look for command usage examples, README, ADRs if any
+
+Write findings into PRD:
+
+* Add to `What I already know`
+* Add constraints/links to `Technical Notes`
+
+---
+
+## Step 2: Classify Complexity (still useful, not gating task creation)
+
+| Complexity   | Criteria                                               | Action                                      |
+| ------------ | ------------------------------------------------------ | ------------------------------------------- |
+| **Trivial**  | Single-line fix, typo, obvious change                  | Skip brainstorm, implement directly         |
+| **Simple**   | Clear goal, 1–2 files, scope well-defined              | Ask 1 confirm question, then implement      |
+| **Moderate** | Multiple files, some ambiguity                         | Light brainstorm (2–3 high-value questions) |
+| **Complex**  | Vague goal, architectural choices, multiple approaches | Full brainstorm                             |
+
+> Note: Task already exists from Step 0. Classification only affects depth of brainstorming.
+
+---
+
+## Step 3: Question Gate (Ask ONLY high-value questions)
+
+Before asking ANY question, run the following gate:
+
+### Gate A — Can I derive this without the user?
+
+If answer is available via:
+
+* repo inspection (code/config)
+* docs/specs/conventions
+* quick market/OSS research
+
+→ **Do not ask.** Fetch it, summarize, update PRD.
+
+### Gate B — Is this a meta/lazy question?
+
+Examples:
+
+* "Should I search?"
+* "Can you paste the code so I can proceed?"
+* "What does the code look like?" (when repo is available)
+
+→ **Do not ask.** Take action.
+
+### Gate C — What type of question is it?
+
+* **Blocking**: cannot proceed without user input
+* **Preference**: multiple valid choices, depends on product/UX/risk preference
+* **Derivable**: should be answered by inspection/research
+
+→ Only ask **Blocking** or **Preference**.
+
+---
+
+## Step 4: Research-first Mode (Mandatory for technical choices)
+
+### Trigger conditions (any → research-first)
+
+* The task involves selecting an approach, library, protocol, framework, template system, plugin mechanism, or CLI UX convention
+* The user asks for "best practice", "how others do it", "recommendation"
+* The user can't reasonably enumerate options
+
+### Delegate to `trellis-research` sub-agent (don't research inline)
+
+For each research topic, **spawn a `trellis-research` sub-agent via the Task tool** — don't do WebFetch / WebSearch / `gh api` inline in the main conversation.
+
+Why:
+- The sub-agent has its own context window → doesn't pollute brainstorm context with raw tool output
+- It persists findings to `{TASK_DIR}/research/<topic>.md` (the contract — see `workflow.md` Phase 1.2)
+- It returns only `{file path, one-line summary}` to the main agent
+- Independent topics can be **parallelized** — spawn multiple sub-agents in one tool call
+
+Agent type: `trellis-research`
+Task description template: "Research <specific question>; persist findings to `{TASK_DIR}/research/<topic-slug>.md`."
+
+❌ Bad (what you must NOT do):
+```
+Main agent: WebFetch(url-A) → WebFetch(url-B) → Bash(gh api ...)
+          → WebSearch(q1) → WebSearch(q2) → ... (10+ inline calls)
+          → Write(research/topic.md)
+```
+→ Pollutes main context with raw HTML/JSON, burns tokens.
+
+✅ Good:
+```
+Main agent: Task(subagent_type="trellis-research",
+                 prompt="Research topic A; persist to research/topic-a.md")
+          + Task(subagent_type="trellis-research",
+                 prompt="Research topic B; persist to research/topic-b.md")
+          + Task(subagent_type="trellis-research",
+                 prompt="Research topic C; persist to research/topic-c.md")
+→ Reads research/topic-{a,b,c}.md after they finish.
+```
+
+### Research steps (to pass into each sub-agent prompt)
+
+Each `trellis-research` sub-agent should:
+
+1. Identify 2–4 comparable tools/patterns for its topic
+2. Summarize common conventions and why they exist
+3. Map conventions onto our repo constraints
+4. Write findings to `{TASK_DIR}/research/<topic>.md`
+
+Main agent then reads the persisted files and produces **2–3 feasible approaches** in PRD.
+
+### Research output format (PRD)
+
+The PRD itself should only reference the persisted research files, not duplicate their content. Add a `## Research References` section pointing at `research/*.md`.
+
+Optionally, add a convergence section with feasible approaches derived from the research:
+
+```markdown
+## Research References
+
+* [`research/<topic-a>.md`](research/<topic-a>.md) — <one-line takeaway>
+* [`research/<topic-b>.md`](research/<topic-b>.md) — <one-line takeaway>
+
+## Research Notes
+
+### What similar tools do
+
+* ...
+* ...
+
+### Constraints from our repo/project
+
+* ...
+
+### Feasible approaches here
+
+**Approach A: <name>** (Recommended)
+
+* How it works:
+* Pros:
+* Cons:
+
+**Approach B: <name>**
+
+* How it works:
+* Pros:
+* Cons:
+
+**Approach C: <name>** (optional)
+
+* ...
+```
+
+Then ask **one** preference question:
+
+* "Which approach do you prefer: A / B / C (or other)?"
+
+---
+
+## Step 5: Expansion Sweep (DIVERGE) — Required after initial understanding
+
+After you can summarize the goal, proactively broaden thinking before converging.
+
+### Expansion categories (keep to 1–2 bullets each)
+
+1. **Future evolution**
+
+   * What might this feature become in 1–3 months?
+   * What extension points are worth preserving now?
+
+2. **Related scenarios**
+
+   * What adjacent commands/flows should remain consistent with this?
+   * Are there parity expectations (create vs update, import vs export, etc.)?
+
+3. **Failure & edge cases**
+
+   * Conflicts, offline/network failure, retries, idempotency, compatibility, rollback
+   * Input validation, security boundaries, permission checks
+
+### Expansion message template (to user)
+
+```markdown
+I understand you want to implement: <current goal>.
+
+Before diving into design, let me quickly diverge to consider three categories (to avoid rework later):
+
+1. Future evolution: <1–2 bullets>
+2. Related scenarios: <1–2 bullets>
+3. Failure/edge cases: <1–2 bullets>
+
+For this MVP, which would you like to include (or none)?
+
+1. Current requirement only (minimal viable)
+2. Add <X> (reserve for future extension)
+3. Add <Y> (improve robustness/consistency)
+4. Other: describe your preference
+```
+
+Then update PRD:
+
+* What's in MVP → `Requirements`
+* What's excluded → `Out of Scope`
+
+---
+
+## Step 6: Q&A Loop (CONVERGE)
+
+### Rules
+
+* One question per message
+* Prefer multiple-choice when possible
+* After each user answer:
+
+  * Update PRD immediately
+  * Move answered items from `Open Questions` → `Requirements`
+  * Update `Acceptance Criteria` with testable checkboxes
+  * Clarify `Out of Scope`
+
+### Question priority (recommended)
+
+1. **MVP scope boundary** (what is included/excluded)
+2. **Preference decisions** (after presenting concrete options)
+3. **Failure/edge behavior** (only for MVP-critical paths)
+4. **Success metrics & Acceptance Criteria** (what proves it works)
+
+### Preferred question format (multiple choice)
+
+```markdown
+For <topic>, which approach do you prefer?
+
+1. **Option A** — <what it means + trade-off>
+2. **Option B** — <what it means + trade-off>
+3. **Option C** — <what it means + trade-off>
+4. **Other** — describe your preference
+```
+
+---
+
+## Step 7: Propose Approaches + Record Decisions (Complex tasks)
+
+After requirements are clear enough, propose 2–3 approaches (if not already done via research-first):
+
+```markdown
+Based on current information, here are 2–3 feasible approaches:
+
+**Approach A: <name>** (Recommended)
+
+* How:
+* Pros:
+* Cons:
+
+**Approach B: <name>**
+
+* How:
+* Pros:
+* Cons:
+
+Which direction do you prefer?
+```
+
+Record the outcome in PRD as an ADR-lite section:
+
+```markdown
+## Decision (ADR-lite)
+
+**Context**: Why this decision was needed
+**Decision**: Which approach was chosen
+**Consequences**: Trade-offs, risks, potential future improvements
+```
+
+---
+
+## Step 8: Final Confirmation + Implementation Plan
+
+When open questions are resolved, confirm complete requirements with a structured summary:
+
+### Final confirmation format
+
+```markdown
+Here's my understanding of the complete requirements:
+
+**Goal**: <one sentence>
+
+**Requirements**:
+
+* ...
+* ...
+
+**Acceptance Criteria**:
+
+* [ ] ...
+* [ ] ...
+
+**Definition of Done**:
+
+* ...
+
+**Out of Scope**:
+
+* ...
+
+**Technical Approach**:
+<brief summary + key decisions>
+
+**Implementation Plan (small PRs)**:
+
+* PR1: <scaffolding + tests + minimal plumbing>
+* PR2: <core behavior>
+* PR3: <edge cases + docs + cleanup>
+
+Does this look correct? If yes, I'll proceed with implementation.
+```
+
+### Subtask Decomposition (Complex Tasks)
+
+For complex tasks with multiple independent work items, create subtasks:
+
+```bash
+# Create child tasks
+CHILD1=$(python3 ./.trellis/scripts/task.py create "Child task 1" --slug child1 --parent "$TASK_DIR")
+CHILD2=$(python3 ./.trellis/scripts/task.py create "Child task 2" --slug child2 --parent "$TASK_DIR")
+
+# Or link existing tasks
+python3 ./.trellis/scripts/task.py add-subtask "$TASK_DIR" "$CHILD_DIR"
+```
+
+---
+
+## PRD Target Structure (final)
+
+`prd.md` should converge to:
+
+```markdown
+# <Task Title>
+
+## Goal
+
+<why + what>
+
+## Requirements
+
+* ...
+
+## Acceptance Criteria
+
+* [ ] ...
+
+## Definition of Done
+
+* ...
+
+## Technical Approach
+
+<key design + decisions>
+
+## Decision (ADR-lite)
+
+Context / Decision / Consequences
+
+## Out of Scope
+
+* ...
+
+## Technical Notes
+
+<constraints, references, files, research notes>
+```
+
+---
+
+## Anti-Patterns (Hard Avoid)
+
+* Asking user for code/context that can be derived from repo
+* Asking user to choose an approach before presenting concrete options
+* Meta questions about whether to research
+* Staying narrowly on the initial request without considering evolution/edges
+* Letting brainstorming drift without updating PRD
+
+---
+
+## Integration with Start Workflow
+
+After brainstorm completes (Step 8 confirmation approved), the flow continues to the Task Workflow's **Phase 2: Prepare for Implementation**:
+
+```text
+Brainstorm
+  Step 0: Create task directory + seed PRD
+  Step 1–7: Discover requirements, research, converge
+  Step 8: Final confirmation → user approves

+# Break the Loop - Deep Bug Analysis
+
+When debug is complete, use this for deep analysis to break the "fix bug -> forget -> repeat" cycle.
+
+---
+
+## Analysis Framework
+
+Analyze the bug you just fixed from these 5 dimensions:
+
+### 1. Root Cause Category
+
+Which category does this bug belong to?
+
+| Category | Characteristics | Example |
+|----------|-----------------|---------|
+| **A. Missing Spec** | No documentation on how to do it | New feature without checklist |
+| **B. Cross-Layer Contract** | Interface between layers unclear | API returns different format than expected |
+| **C. Change Propagation Failure** | Changed one place, missed others | Changed function signature, missed call sites |
+| **D. Test Coverage Gap** | Unit test passes, integration fails | Works alone, breaks when combined |
+| **E. Implicit Assumption** | Code relies on undocumented assumption | Timestamp seconds vs milliseconds |
+
+### 2. Why Fixes Failed (if applicable)
+
+If you tried multiple fixes before succeeding, analyze each failure:
+
+- **Surface Fix**: Fixed symptom, not root cause
+- **Incomplete Scope**: Found root cause, didn't cover all cases
+- **Tool Limitation**: grep missed it, type check wasn't strict
+- **Mental Model**: Kept looking in same layer, didn't think cross-layer
+
+### 3. Prevention Mechanisms
+
+What mechanisms would prevent this from happening again?
+
+| Type | Description | Example |
+|------|-------------|---------|
+| **Documentation** | Write it down so people know | Update thinking guide |
+| **Architecture** | Make the error impossible structurally | Type-safe wrappers |
+| **Compile-time** | Strict type checking, no escape hatches | Signature change causes compile error |
+| **Runtime** | Monitoring, alerts, scans | Detect orphan entities |
+| **Test Coverage** | E2E tests, integration tests | Verify full flow |
+| **Code Review** | Checklist, PR template | "Did you check X?" |
+
+### 4. Systematic Expansion
+
+What broader problems does this bug reveal?
+
+- **Similar Issues**: Where else might this problem exist?
+- **Design Flaw**: Is there a fundamental architecture issue?
+- **Process Flaw**: Is there a development process improvement?
+- **Knowledge Gap**: Is the team missing some understanding?
+
+### 5. Knowledge Capture
+
+Solidify insights into the system:
+
+- [ ] Update `.trellis/spec/guides/` thinking guides
+- [ ] Update relevant `.trellis/spec/` docs
+- [ ] Create issue record (if applicable)
+- [ ] Create feature ticket for root fix
+- [ ] Update check guidelines if needed
+

+## Core Philosophy
+
+> **The value of debugging is not in fixing the bug, but in making this class of bugs never happen again.**
+
+Three levels of insight:
+1. **Tactical**: How to fix THIS bug
+2. **Strategic**: How to prevent THIS CLASS of bugs
+3. **Philosophical**: How to expand thinking patterns
+
+30 minutes of analysis saves 30 hours of future debugging.
+
+---
+
+## After Analysis: Immediate Actions
+
+**IMPORTANT**: After completing the analysis above, you MUST immediately:
+
+1. **Update spec/guides** - Don't just list TODOs, actually update the relevant files:
+   - If it's a cross-platform issue → update `cross-platform-thinking-guide.md`
+   - If it's a cross-layer issue → update `cross-layer-thinking-guide.md`
+   - If it's a code reuse issue → update `code-reuse-thinking-guide.md`
+   - If it's domain-specific → update `backend/*.md` or `frontend/*.md`
+
+2. **Sync templates** - After updating `.trellis/spec/`, sync to `src/templates/markdown/spec/`
+
+3. **Commit the spec updates** - This is the primary output, not just the analysis text
+
+> **The analysis is worthless if it stays in chat. The value is in the updated specs.**

+---
+
+# Code Quality Check
+
+Comprehensive quality verification for recently written code. Combines spec compliance, cross-layer safety, and pre-commit checks.
+
+---
+
+## Step 1: Identify What Changed
+
+```bash
+git diff --name-only HEAD
+git status
+```
+
+## Step 2: Read Applicable Specs
+
+```bash
+python3 ./.trellis/scripts/get_context.py --mode packages
+```
+
+For each changed package/layer, read the spec index and follow its **Quality Check** section:
+
+```bash
+cat .trellis/spec/<package>/<layer>/index.md
+```
+
+Read the specific guideline files referenced — the index is a pointer, not the goal.
+
+## Step 3: Run Project Checks
+
+Run the project's lint, type-check, and test commands. Fix any failures before proceeding.
+
+## Step 4: Review Against Checklist
+
+### Code Quality
+
+- [ ] Linter passes?
+- [ ] Type checker passes (if applicable)?
+- [ ] Tests pass?
+- [ ] No debug logging left in?
+- [ ] No suppressed warnings or type-safety bypasses?
+
+### Test Coverage
+
+- [ ] New function → unit test added?
+- [ ] Bug fix → regression test added?
+- [ ] Changed behavior → existing tests updated?
+
+### Spec Sync
+
+- [ ] Does `.trellis/spec/` need updates? (new patterns, conventions, lessons learned)
+
+> "If I fixed a bug or discovered something non-obvious, should I document it so future me won't hit the same issue?" → If YES, update the relevant spec doc.
+
+## Step 5: Cross-Layer Dimensions (if applicable)
+
+Skip this step if your change is confined to a single layer.
+
+### A. Data Flow (changes touch 3+ layers)
+
+- [ ] Read flow traces correctly: Storage → Service → API → UI
+- [ ] Write flow traces correctly: UI → API → Service → Storage
+- [ ] Types/schemas correctly passed between layers?
+- [ ] Errors properly propagated to caller?
+
+### B. Code Reuse (modifying constants, creating utilities)
+
+- [ ] Searched for existing similar code before creating new?
+  ```bash
+  grep -r "pattern" src/
+  ```
+- [ ] If 2+ places define same value → extracted to shared constant?
+- [ ] After batch modification, all occurrences updated?
+
+### C. Import/Dependency (creating new files)
+
+- [ ] Correct import paths (relative vs absolute)?
+- [ ] No circular dependencies?
+
+### D. Same-Layer Consistency
+
+- [ ] Other places using the same concept are consistent?
+
+---
+
+## Step 6: Report and Fix
+
+Report violations found and fix them directly. Re-run project checks after fixes.

+# Update Code-Spec - Capture Executable Contracts
+
+When you learn something valuable (from debugging, implementing, or discussion), use this to update the relevant code-spec documents.
+
+**Timing**: After completing a task, fixing a bug, or discovering a new pattern
+
+---
+
+## Code-Spec First Rule (CRITICAL)
+
+In this project, "spec" for implementation work means **code-spec**:
+- Executable contracts (not principle-only text)
+- Concrete signatures, payload fields, env keys, and boundary behavior
+- Testable validation/error behavior
+
+If the change touches infra or cross-layer contracts, code-spec depth is mandatory.
+
+### Mandatory Triggers
+
+Apply code-spec depth when the change includes any of:
+- New/changed command or API signature
+- Cross-layer request/response contract change
+- Database schema/migration change
+- Infra integration (storage, queue, cache, secrets, env wiring)
+
+### Mandatory Output (7 Sections)
+
+For triggered tasks, include all sections below:
+1. Scope / Trigger
+2. Signatures (command/API/DB)
+3. Contracts (request/response/env)
+4. Validation & Error Matrix
+5. Good/Base/Bad Cases
+6. Tests Required (with assertion points)
+7. Wrong vs Correct (at least one pair)
+
+---
+
+## When to Update Code-Specs
+
+| Trigger | Example | Target Spec |
+|---------|---------|-------------|
+| **Implemented a feature** | Added a new integration or module | Relevant spec file |
+| **Made a design decision** | Chose extensibility pattern over simplicity | Relevant spec + "Design Decisions" section |
+| **Fixed a bug** | Found a subtle issue with error handling | Relevant spec (e.g., error-handling docs) |
+| **Discovered a pattern** | Found a better way to structure code | Relevant spec file |
+| **Hit a gotcha** | Learned that X must be done before Y | Relevant spec + "Common Mistakes" section |
+| **Established a convention** | Team agreed on naming pattern | Quality guidelines |
+| **New thinking trigger** | "Don't forget to check X before doing Y" | `guides/*.md` (as a checklist item) |
+
+**Key Insight**: Code-spec updates are NOT just for problems. Every feature implementation contains design decisions and contracts that future AI/developers need to execute safely.
+
+---
+
+## Spec Structure Overview
+
+```
+.trellis/spec/
+├── <layer>/           # Per-layer coding standards (e.g., backend/, frontend/, api/)
+│   ├── index.md       # Overview and links
+│   └── *.md           # Topic-specific guidelines
+└── guides/            # Thinking checklists (NOT coding specs!)
+    ├── index.md       # Guide index
+    └── *.md           # Topic-specific guides
+```
+
+### CRITICAL: Code-Spec vs Guide - Know the Difference
+
+| Type | Location | Purpose | Content Style |
+|------|----------|---------|---------------|
+| **Code-Spec** | `<layer>/*.md` | Tell AI "how to implement safely" | Signatures, contracts, matrices, cases, test points |
+| **Guide** | `guides/*.md` | Help AI "what to think about" | Checklists, questions, pointers to specs |
+
+**Decision Rule**: Ask yourself:
+
+- "This is **how to write** the code" → Put in a spec layer directory
+- "This is **what to consider** before writing" → Put in `guides/`
+
+**Example**:
+
+| Learning | Wrong Location | Correct Location |
+|----------|----------------|------------------|
+| "Use API X not API Y for this task" | ❌ `guides/` (too specific for a thinking guide) | ✅ Relevant spec file (concrete convention) |
+| "Remember to check X when doing Y" | ❌ Spec file (too abstract for a spec) | ✅ `guides/` (thinking checklist) |
+
+**Guides should be short checklists that point to specs**, not duplicate the detailed rules.
+
+---
+
+## Update Process
+
+### Step 1: Identify What You Learned
+
+Answer these questions:
+
+1. **What did you learn?** (Be specific)
+2. **Why is it important?** (What problem does it prevent?)
+3. **Where does it belong?** (Which spec file?)
+
+### Step 2: Classify the Update Type
+
+| Type | Description | Action |
+|------|-------------|--------|
+| **Design Decision** | Why we chose approach X over Y | Add to "Design Decisions" section |
+| **Project Convention** | How we do X in this project | Add to relevant section with examples |
+| **New Pattern** | A reusable approach discovered | Add to "Patterns" section |
+| **Forbidden Pattern** | Something that causes problems | Add to "Anti-patterns" or "Don't" section |
+| **Common Mistake** | Easy-to-make error | Add to "Common Mistakes" section |
+| **Convention** | Agreed-upon standard | Add to relevant section |
+| **Gotcha** | Non-obvious behavior | Add warning callout |
+
+### Step 3: Read the Target Code-Spec
+
+Before editing, read the current code-spec to:
+- Understand existing structure
+- Avoid duplicating content
+- Find the right section for your update
+
+```bash
+cat .trellis/spec/<category>/<file>.md
+```
+
+### Step 4: Make the Update
+
+Follow these principles:
+
+1. **Be Specific**: Include concrete examples, not just abstract rules
+2. **Explain Why**: State the problem this prevents
+3. **Show Contracts**: Add signatures, payload fields, and error behavior
+4. **Show Code**: Add code snippets for key patterns
+5. **Keep it Short**: One concept per section
+
+### Step 5: Update the Index (if needed)
+
+If you added a new section or the code-spec status changed, update the category's `index.md`.

+## Interactive Mode
+
+If you're unsure what to update, answer these prompts:
+
+1. **What did you just finish?**
+   - [ ] Fixed a bug
+   - [ ] Implemented a feature
+   - [ ] Refactored code
+   - [ ] Had a discussion about approach
+
+2. **What did you learn or decide?**

+   - [ ] Frontend code
+   - [ ] Cross-layer data flow
+   - [ ] Code organization/reuse
+   - [ ] Quality/testing
+

+
+## Quality Checklist
+
+Before finishing your code-spec update:
+
+- [ ] Is the content specific and actionable?
+- [ ] Did you include a code example?
+- [ ] Did you explain WHY, not just WHAT?
+- [ ] Did you include executable signatures/contracts?
+- [ ] Did you include validation and error matrix?
+- [ ] Did you include Good/Base/Bad cases?
+- [ ] Did you include required tests with assertion points?
+- [ ] Is it in the right code-spec file?
+- [ ] Does it duplicate existing content?
+- [ ] Would a new team member understand it?
+
+---
+
+## Relationship to Other Commands
+
+```
+Development Flow:
+  Learn something → /trellis-update-spec → Knowledge captured
+       ↑                                  ↓
+  /trellis-break-loop ←──────────────────── Future sessions benefit
+  (deep bug analysis)
+```
+
+- `/trellis-break-loop` - Analyzes bugs deeply, often reveals spec updates needed
+- `/trellis-update-spec` - Actually makes the updates
+- `/trellis-finish-work` - Reminds you to check if specs need updates
+
+---
+
+## Core Philosophy
+
+> **Code-specs are living documents. Every debugging session, every "aha moment" is an opportunity to make the implementation contract clearer.**
+
+The goal is **institutional memory**:
+- What one person learns, everyone benefits from
+- What AI learns in one session, persists to future sessions
+- Mistakes become documented guardrails

+
+## Overview
+
+This directory contains guidelines for backend development. Fill in each file with your project's specific conventions.
+
+---
+
+## Guidelines Index
+
+| Guide | Description | Status |
+|-------|-------------|--------|
+| [Directory Structure](./directory-structure.md) | Module organization and file layout | To fill |
+| [Database Guidelines](./database-guidelines.md) | ORM patterns, queries, migrations | To fill |
+| [Error Handling](./error-handling.md) | Error types, handling strategies | To fill |
+| [Quality Guidelines](./quality-guidelines.md) | Code standards, forbidden patterns | To fill |
+| [Logging Guidelines](./logging-guidelines.md) | Structured logging, log levels | To fill |
+
+---
+
+## How to Fill These Guidelines
+
+For each guideline file:
+
+1. Document your project's **actual conventions** (not ideals)
+2. Include **code examples** from your codebase
+3. List **forbidden patterns** and why
+4. Add **common mistakes** your team has made
+
+The goal is to help AI assistants and new team members understand how YOUR project works.
+
