description: "Discovers and injects project-specific coding guidelines from .trellis/spec/ before implementation begins. 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: "Collaborative requirements discovery session optimized for AI coding workflows. Creates task directories, seeds PRDs, runs codebase research, proposes concrete implementation approaches with trade-offs, and converges on MVP scope through structured Q&A. Use when requirements are unclear, multiple implementation paths exist, trade-offs need evaluation, or a complex feature needs scoping before development."

# 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 `/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 23 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, 12 files, scope well-defined | Ask 1 confirm question, then implement |
| **Moderate** | Multiple files, some ambiguity | Light brainstorm (23 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
### Research steps
1. Identify 24 comparable tools/patterns
2. Summarize common conventions and why they exist
3. Map conventions onto our repo constraints
4. Produce **23 feasible approaches** for our project
### Research output format (PRD)
Add a section in PRD (either within Technical Notes or as its own):
```markdown
## 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 12 bullets each)
1. **Future evolution**
* What might this feature become in 13 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: <12 bullets>
2. Related scenarios: <12 bullets>
3. Failure/edge cases: <12 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 23 approaches (if not already done via research-first):
```markdown
Based on current information, here are 23 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 17: 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 skill 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** | TypeScript strict, no any | 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 `.trellis/spec/backend/` or `frontend/` docs
- [ ] Create issue record (if applicable)
- [ ] Create feature ticket for root fix
- [ ] Update check skills 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.**

# Cross-Layer Check
Check if your changes considered all dimensions. Most bugs come from "didn't think of it", not lack of technical skill.
> **Note**: This is a **post-implementation** safety net. Ideally, read the [Pre-Implementation Checklist](.trellis/spec/guides/pre-implementation-checklist.md) **before** writing code.

## Execution Steps
### 1. Identify Change Scope
```bash
git status
git diff --name-only
```
### 2. Select Applicable Check Dimensions
Based on your change type, execute relevant checks below:
---
## Dimension A: Cross-Layer Data Flow (Required when 3+ layers)
**Trigger**: Changes involve 3 or more layers
| Layer | Common Locations |
|-------|------------------|
| API/Routes | `routes/`, `api/`, `handlers/`, `controllers/` |
| Service/Business Logic | `services/`, `lib/`, `core/`, `domain/` |
| Database/Storage | `db/`, `models/`, `repositories/`, `schema/` |
| UI/Presentation | `components/`, `views/`, `templates/`, `pages/` |
| Utility | `utils/`, `helpers/`, `common/` |
**Checklist**:
- [ ] Read flow: Database -> Service -> API -> UI
- [ ] Write flow: UI -> API -> Service -> Database
- [ ] Types/schemas correctly passed between layers?
- [ ] Errors properly propagated to caller?
- [ ] Loading/pending states handled at each layer?
**Detailed Guide**: `.trellis/spec/guides/cross-layer-thinking-guide.md`
---
## Dimension B: Code Reuse (Required when modifying constants/config)
**Trigger**:
- Modifying UI constants (label, icon, color)
- Modifying any hardcoded value
- Seeing similar code in multiple places
- Creating a new utility/helper function
- Just finished batch modifications across files
**Checklist**:
- [ ] Search first: How many places define this value?
```bash
# Search in source files (adjust extensions for your project)
grep -r "value-to-change" src/
```
- [ ] If 2+ places define same value -> Should extract to shared constant
- [ ] After modification, all usage sites updated?
- [ ] If creating utility: Does similar utility already exist?
**Detailed Guide**: `.trellis/spec/guides/code-reuse-thinking-guide.md`
---
## Dimension B2: New Utility Functions
**Trigger**: About to create a new utility/helper function
**Checklist**:
- [ ] Search for existing similar utilities first
```bash
grep -r "functionNamePattern" src/
```
- [ ] If similar exists, can you extend it instead?
- [ ] If creating new, is it in the right location (shared vs domain-specific)?
---
## Dimension B3: After Batch Modifications
**Trigger**: Just modified similar patterns in multiple files
**Checklist**:
- [ ] Did you check ALL files with similar patterns?
```bash
grep -r "patternYouChanged" src/
```
- [ ] Any files missed that should also be updated?
- [ ] Should this pattern be abstracted to prevent future duplication?
---
## Dimension C: Import/Dependency Paths (Required when creating new files)
**Trigger**: Creating new source files
**Checklist**:
- [ ] Using correct import paths (relative vs absolute)?
- [ ] No circular dependencies?
- [ ] Consistent with project's module organization?
---
## Dimension D: Same-Layer Consistency
**Trigger**:
- Modifying display logic or formatting
- Same domain concept used in multiple places
**Checklist**:
- [ ] Search for other places using same concept
```bash
grep -r "ConceptName" src/
```
- [ ] Are these usages consistent?
- [ ] Should they share configuration/constants?
---
## Common Issues Quick Reference
| Issue | Root Cause | Prevention |
|-------|------------|------------|
| Changed one place, missed others | Didn't search impact scope | `grep` before changing |
| Data lost at some layer | Didn't check data flow | Trace data source to destination |
| Type/schema mismatch | Cross-layer types inconsistent | Use shared type definitions |
| UI/output inconsistent | Same concept in multiple places | Extract shared constants |
| Similar utility exists | Didn't search first | Search before creating |
| Batch fix incomplete | Didn't verify all occurrences | grep after fixing |

# Finish Work - Pre-Commit Checklist
Before submitting or committing, use this checklist to ensure work completeness.
**Timing**: After code is written and tested, before commit
---
## Checklist
### 1. Code Quality
```bash
# Must pass
pnpm lint
pnpm type-check
pnpm test
```
- [ ] `pnpm lint` passes with 0 errors?
- [ ] `pnpm type-check` passes with no type errors?
- [ ] Tests pass?
- [ ] No `console.log` statements (use logger)?
- [ ] No non-null assertions (the `x!` operator)?
- [ ] No `any` types?
### 2. Code-Spec Sync
**Code-Spec Docs**:
- [ ] Does `.trellis/spec/backend/` need updates?
- New patterns, new modules, new conventions
- [ ] Does `.trellis/spec/frontend/` need updates?
- New components, new hooks, new patterns
- [ ] Does `.trellis/spec/guides/` need updates?
- New cross-layer flows, lessons from bugs
**Key Question**:
> "If I fixed a bug or discovered something non-obvious, should I document it so future me (or others) won't hit the same issue?"
If YES -> Update the relevant code-spec doc.
### 2.5. Code-Spec Hard Block (Infra/Cross-Layer)
If this change touches infra or cross-layer contracts, this is a blocking checklist:
- [ ] Spec content is executable (real signatures/contracts), not principle-only text
- [ ] Includes file path + command/API name + payload field names
- [ ] Includes validation and error matrix
- [ ] Includes Good/Base/Bad cases
- [ ] Includes required tests and assertion points
**Block Rule**:
If infra/cross-layer changed but the related spec is still abstract, do NOT finish. Run `/update-spec` manually first.
### 3. API Changes
If you modified API endpoints:
- [ ] Input schema updated?
- [ ] Output schema updated?
- [ ] API documentation updated?
- [ ] Client code updated to match?
### 4. Database Changes
If you modified database schema:
- [ ] Migration file created?
- [ ] Schema file updated?
- [ ] Related queries updated?
- [ ] Seed data updated (if applicable)?
### 5. Cross-Layer Verification
If the change spans multiple layers:
- [ ] Data flows correctly through all layers?
- [ ] Error handling works at each boundary?
- [ ] Types are consistent across layers?
- [ ] Loading states handled?
### 6. Manual Testing
- [ ] Feature works in browser/app?
- [ ] Edge cases tested?
- [ ] Error states tested?
- [ ] Works after page refresh?

# Improve Unit Tests (UT)
Use this skill to improve test coverage after code changes.
## Usage
```text
/improve-ut

## Source of Truth
Discover and read unit-test specs dynamically:
```bash
# Discover available packages and their spec layers
python3 ./.trellis/scripts/get_context.py --mode packages
```
Look for packages with `unit-test` spec layer in the output. For each discovered `unit-test/` directory, read all relevant spec files inside it (for example `index.md`, `conventions.md`, `integration-patterns.md`, `mock-strategies.md`).
> If this skill conflicts with the unit-test specs, the specs win.

# Integrate Skill into Project Guidelines
Adapt and integrate a reusable skill into your project's development guidelines (not directly into project code).
## Usage
```
/integrate-skill <skill-name>
```
**Examples**:
```
/integrate-skill frontend-design
/integrate-skill mcp-builder
```
## Core Principle
> [!] **Important**: The goal of skill integration is to update **development guidelines**, not to generate project code directly.
>
> - Guidelines content -> Write to `.trellis/spec/{target}/doc.md`
> - Code examples -> Place in `.trellis/spec/{target}/examples/skills/<skill-name>/`
> - Example files -> Use `.template` suffix (e.g., `component.tsx.template`) to avoid IDE errors
>
> Where `{target}` is `frontend` or `backend`, determined by skill type.
## Execution Steps
### 1. Read Skill Content
Locate and read the skill instructions:
- `.agent/workflows/<workflow-name>.md` in the repository
- Skill list in `AGENTS.md` (when available in current context)
If the skill cannot be found, ask the user for the source path or repository.
### 2. Determine Integration Target
Based on skill type, determine which guidelines to update:
| Skill Category | Integration Target |
|----------------|-------------------|
| UI/Frontend (`frontend-design`, `web-artifacts-builder`) | `.trellis/spec/frontend/` |
| Backend/API (`mcp-builder`) | `.trellis/spec/backend/` |
| Documentation (`doc-coauthoring`, `docx`, `pdf`) | `.trellis/` or create dedicated guidelines |
| Testing (`webapp-testing`) | `.trellis/spec/frontend/` (E2E) |
### 3. Analyze Skill Content
Extract from the skill:
- **Core concepts**: How the skill works and key concepts
- **Best practices**: Recommended approaches
- **Code patterns**: Reusable code templates
- **Caveats**: Common issues and solutions
### 4. Execute Integration
#### 4.1 Update Guidelines Document
Add a new section to the corresponding `doc.md`:
```markdown
@@@section:skill-<skill-name>
## # <Skill Name> Integration Guide
### Overview
[Core functionality and use cases of the skill]
### Project Adaptation
[How to use this skill in the current project]
### Usage Steps
1. [Step 1]
2. [Step 2]
### Caveats
- [Project-specific constraints]
- [Differences from default behavior]
### Reference Examples
See `examples/skills/<skill-name>/`
@@@/section:skill-<skill-name>
```
#### 4.2 Create Examples Directory (if code examples exist)
```bash
# Directory structure ({target} = frontend or backend)
.trellis/spec/{target}/
|-- doc.md # Add skill-related section
|-- index.md # Update index
+-- examples/
+-- skills/
+-- <skill-name>/
|-- README.md # Example documentation
|-- example-1.ts.template # Code example (use .template suffix)
+-- example-2.tsx.template
```
**File naming conventions**:
- Code files: `<name>.<ext>.template` (e.g., `component.tsx.template`)
- Config files: `<name>.config.template` (e.g., `tailwind.config.template`)
- Documentation: `README.md` (normal suffix)
#### 4.3 Update Index File
Add to the Quick Navigation table in `index.md`:
```markdown
| <Skill-related task> | <Section name> | `skill-<skill-name>` |
```
### 5. Generate Integration Report
---
## Skill Integration Report: `<skill-name>`
### # Overview
- **Skill description**: [Functionality description]
- **Integration target**: `.trellis/spec/{target}/`
### # Tech Stack Compatibility
| Skill Requirement | Project Status | Compatibility |
|-------------------|----------------|---------------|
| [Tech 1] | [Project tech] | [OK]/[!]/[X] |
### # Integration Locations
| Type | Path |
|------|------|
| Guidelines doc | `.trellis/spec/{target}/doc.md` (section: `skill-<name>`) |
| Code examples | `.trellis/spec/{target}/examples/skills/<name>/` |
| Index update | `.trellis/spec/{target}/index.md` |
> `{target}` = `frontend` or `backend`
### # Dependencies (if needed)
```bash
# Install required dependencies (adjust for your package manager)
npm install <package>
# or
pnpm add <package>
# or
yarn add <package>
```
### [OK] Completed Changes
- [ ] Added `@@@section:skill-<name>` section to `doc.md`

name: onboard
description: "Interactive three-part onboarding for new team members to the Trellis AI-assisted workflow system. Covers core philosophy (AI memory, project-specific knowledge, context drift), system structure and command deep-dives, real-world workflow examples, and guideline customization. Use when a new developer joins the project, someone needs to understand the Trellis workflow, or project guidelines need initial setup."
---
You are a senior developer onboarding a new team member to this project's AI-assisted workflow system.
YOUR ROLE: Be a mentor and teacher. Don't just list steps - EXPLAIN the underlying principles, why each skill exists, what problem it solves at a fundamental level.
## CRITICAL INSTRUCTION - YOU MUST COMPLETE ALL SECTIONS
This onboarding has THREE equally important parts:
**PART 1: Core Concepts** (Sections: CORE PHILOSOPHY, SYSTEM STRUCTURE, SKILL DEEP DIVE)
- Explain WHY this workflow exists
- Explain WHAT each skill does and WHY
**PART 2: Real-World Examples** (Section: REAL-WORLD WORKFLOW EXAMPLES)
- Walk through ALL 5 examples in detail
- For EACH step in EACH example, explain:
- PRINCIPLE: Why this step exists
- WHAT HAPPENS: What the skill actually does
- IF SKIPPED: What goes wrong without it
**PART 3: Customize Your Development Guidelines** (Section: CUSTOMIZE YOUR DEVELOPMENT GUIDELINES)
- Check if project guidelines are still empty templates
- If empty, guide the developer to fill them with project-specific content
- Explain the customization workflow
DO NOT skip any part. All three parts are essential:
- Part 1 teaches the concepts
- Part 2 shows how concepts work in practice
- Part 3 ensures the project has proper guidelines for AI to follow
After completing ALL THREE parts, ask the developer about their first task.
---
## CORE PHILOSOPHY: Why This Workflow Exists
AI-assisted development has three fundamental challenges:
### Challenge 1: AI Has No Memory
Every AI session starts with a blank slate. Unlike human engineers who accumulate project knowledge over weeks/months, AI forgets everything when a session ends.
**The Problem**: Without memory, AI asks the same questions repeatedly, makes the same mistakes, and can't build on previous work.
**The Solution**: The `.trellis/workspace/` system captures what happened in each session - what was done, what was learned, what problems were solved. The `/start` skill reads this history at session start, giving AI "artificial memory."
### Challenge 2: AI Has Generic Knowledge, Not Project-Specific Knowledge
AI models are trained on millions of codebases - they know general patterns for React, TypeScript, databases, etc. But they don't know YOUR project's conventions.
**The Problem**: AI writes code that "works" but doesn't match your project's style. It uses patterns that conflict with existing code. It makes decisions that violate unwritten team rules.
**The Solution**: The `.trellis/spec/` directory contains project-specific guidelines. The `$before-*-dev` skills inject this specialized knowledge into AI context before coding starts.
### Challenge 3: AI Context Window Is Limited
Even after injecting guidelines, AI has limited context window. As conversation grows, earlier context (including guidelines) gets pushed out or becomes less influential.
**The Problem**: AI starts following guidelines, but as the session progresses and context fills up, it "forgets" the rules and reverts to generic patterns.
**The Solution**: The `/check-*` skills re-verify code against guidelines AFTER writing, catching drift that occurred during development. The `/finish-work` skill does a final holistic review.
---
## SYSTEM STRUCTURE
```

|-- .developer # Your identity (gitignored)
|-- workflow.md # Complete workflow documentation

### Understanding spec/ subdirectories
**frontend/** - Single-layer frontend knowledge:
- Component patterns (how to write components in THIS project)
- State management rules (Redux? Zustand? Context?)
- Styling conventions (CSS modules? Tailwind? Styled-components?)
- Hook patterns (custom hooks, data fetching)
**backend/** - Single-layer backend knowledge:
- API design patterns (REST? GraphQL? tRPC?)
- Database conventions (query patterns, migrations)
- Error handling standards
- Logging and monitoring rules
**guides/** - Cross-layer thinking guides:
- Code reuse thinking guide
- Cross-layer thinking guide
- Pre-implementation checklists
---
## SKILL DEEP DIVE
### /start - Restore AI Memory
**WHY IT EXISTS**:
When a human engineer joins a project, they spend days/weeks learning: What is this project? What's been built? What's in progress? What's the current state?
AI needs the same onboarding - but compressed into seconds at session start.
**WHAT IT ACTUALLY DOES**:
1. Reads developer identity (who am I in this project?)
2. Checks git status (what branch? uncommitted changes?)
3. Reads recent session history from `workspace/` (what happened before?)
4. Identifies active features (what's in progress?)
5. Understands current project state before making any changes
**WHY THIS MATTERS**:
- Without /start: AI is blind. It might work on wrong branch, conflict with others' work, or redo already-completed work.
- With /start: AI knows project context, can continue where previous session left off, avoids conflicts.
---
### /before-dev - Inject Specialized Knowledge
**WHY IT EXISTS**:
AI models have "pre-trained knowledge" - general patterns from millions of codebases. But YOUR project has specific conventions that differ from generic patterns.
**WHAT IT ACTUALLY DOES**:
1. Discovers spec layers via `get_context.py --mode packages` and reads relevant guidelines
2. Loads project-specific patterns into AI's working context:
- Component naming conventions
- State management patterns
- Database query patterns
- Error handling standards
**WHY THIS MATTERS**:
- Without before-dev: AI writes generic code that doesn't match project style.
- With before-dev: AI writes code that looks like the rest of the codebase.
---
### /check - Combat Context Drift
**WHY IT EXISTS**:
AI context window has limited capacity. As conversation progresses, guidelines injected at session start become less influential. This causes "context drift."
**WHAT IT ACTUALLY DOES**:
1. Re-reads the guidelines that were injected earlier
2. Compares written code against those guidelines
3. Runs type checker and linter
4. Identifies violations and suggests fixes
**WHY THIS MATTERS**:
- Without check-*: Context drift goes unnoticed, code quality degrades.
- With check-*: Drift is caught and corrected before commit.
---
### /check-cross-layer - Multi-Dimension Verification
**WHY IT EXISTS**:
Most bugs don't come from lack of technical skill - they come from "didn't think of it":
- Changed a constant in one place, missed 5 other places
- Modified database schema, forgot to update the API layer
- Created a utility function, but similar one already exists
**WHAT IT ACTUALLY DOES**:
1. Identifies which dimensions your change involves
2. For each dimension, runs targeted checks:
- Cross-layer data flow
- Code reuse analysis
- Import path validation
- Consistency checks
---
### /finish-work - Holistic Pre-Commit Review
**WHY IT EXISTS**:
The `/check-*` skills focus on code quality within a single layer. But real changes often have cross-cutting concerns.
**WHAT IT ACTUALLY DOES**:
1. Reviews all changes holistically
2. Checks cross-layer consistency
3. Identifies broader impacts
4. Checks if new patterns should be documented
---
### /record-session - Persist Memory for Future
**WHY IT EXISTS**:
All the context AI built during this session will be lost when session ends. The next session's `/start` needs this information.
**WHAT IT ACTUALLY DOES**:
1. Records session summary to `workspace/{developer}/journal-N.md`
2. Captures what was done, learned, and what's remaining
3. Updates index files for quick lookup
---
## REAL-WORLD WORKFLOW EXAMPLES
### Example 1: Bug Fix Session
**[1/8] /start** - AI needs project context before touching code
**[2/8] python3 ./.trellis/scripts/task.py create "Fix bug" --slug fix-bug** - Track work for future reference
**[3/8] /before-dev** - Inject project-specific development guidelines
**[4/8] Investigate and fix the bug** - Actual development work
**[5/8] /check** - Re-verify code against guidelines
**[6/8] /finish-work** - Holistic cross-layer review
**[7/8] Human tests and commits** - Human validates before code enters repo
**[8/8] /record-session** - Persist memory for future sessions
### Example 2: Planning Session (No Code)
**[1/4] /start** - Context needed even for non-coding work
**[2/4] python3 ./.trellis/scripts/task.py create "Planning task" --slug planning-task** - Planning is valuable work
**[3/4] Review docs, create subtask list** - Actual planning work
**[4/4] /record-session (with --summary)** - Planning decisions must be recorded
### Example 3: Code Review Fixes
**[1/6] /start** - Resume context from previous session
**[2/6] /before-dev** - Re-inject guidelines before fixes
**[3/6] Fix each CR issue** - Address feedback with guidelines in context
**[4/6] /check** - Verify fixes did not introduce new issues
**[5/6] /finish-work** - Document lessons from CR
**[6/6] Human commits, then /record-session** - Preserve CR lessons
### Example 4: Large Refactoring
**[1/5] /start** - Clear baseline before major changes
**[2/5] Plan phases** - Break into verifiable chunks
**[3/5] Execute phase by phase with /check-* after each** - Incremental verification
**[4/5] /finish-work** - Check if new patterns should be documented
**[5/5] Record with multiple commit hashes** - Link all commits to one feature
### Example 5: Debug Session
**[1/6] /start** - See if this bug was investigated before
**[2/6] /before-dev** - Guidelines might document known gotchas
**[3/6] Investigation** - Actual debugging work
**[4/6] /check** - Verify debug changes do not break other things
**[5/6] /finish-work** - Debug findings might need documentation
**[6/6] Human commits, then /record-session** - Debug knowledge is valuable
---
## KEY RULES TO EMPHASIZE
1. **AI NEVER commits** - Human tests and approves. AI prepares, human validates.
2. **Guidelines before code** - `$before-*-dev` skills inject project knowledge.
3. **Check after code** - `/check-*` skills catch context drift.
4. **Record everything** - /record-session persists memory.
---
# PART 3: Customize Your Development Guidelines
After explaining Part 1 and Part 2, check if the project's development guidelines need customization.
## Step 1: Check Current Guidelines Status
Check if `.trellis/spec/` contains empty templates or customized guidelines:
```bash
# Check if files are still empty templates (look for placeholder text)
grep -l "To be filled by the team" .trellis/spec/backend/*.md 2>/dev/null | wc -l
grep -l "To be filled by the team" .trellis/spec/frontend/*.md 2>/dev/null | wc -l
```
## Step 2: Determine Situation
**Situation A: First-time setup (empty templates)**
If guidelines are empty templates (contain "To be filled by the team"), this is the first time using Trellis in this project.
Explain to the developer:
"I see that the development guidelines in `.trellis/spec/` are still empty templates. This is normal for a new Trellis setup!
The templates contain placeholder text that needs to be replaced with YOUR project's actual conventions. Without this, `$before-*-dev` skills won't provide useful guidance.
**Your first task should be to fill in these guidelines:**
1. Look at your existing codebase
2. Identify the patterns and conventions already in use
3. Document them in the guideline files
For example, for `.trellis/spec/backend/database-guidelines.md`:
- What ORM/query library does your project use?
- How are migrations managed?
- What naming conventions for tables/columns?
Would you like me to help you analyze your codebase and fill in these guidelines?"
**Situation B: Guidelines already customized**
If guidelines have real content (no "To be filled" placeholders), this is an existing setup.
Explain to the developer:
"Great! Your team has already customized the development guidelines. You can start using `$before-*-dev` skills right away.
I recommend reading through `.trellis/spec/` to familiarize yourself with the team's coding standards."
## Step 3: Help Fill Guidelines (If Empty)
If the developer wants help filling guidelines, create a feature to track this:
```bash
python3 ./.trellis/scripts/task.py create "Fill spec guidelines" --slug fill-spec-guidelines
```
Then systematically analyze the codebase and fill each guideline file:
1. **Analyze the codebase** - Look at existing code patterns
2. **Document conventions** - Write what you observe, not ideals
3. **Include examples** - Reference actual files in the project
4. **List forbidden patterns** - Document anti-patterns the team avoids
Work through one file at a time:
- `backend/directory-structure.md`
- `backend/database-guidelines.md`
- `backend/error-handling.md`
- `backend/quality-guidelines.md`
- `backend/logging-guidelines.md`
- `frontend/directory-structure.md`
- `frontend/component-guidelines.md`
- `frontend/hook-guidelines.md`
- `frontend/state-management.md`
- `frontend/quality-guidelines.md`
- `frontend/type-safety.md`

[!] **Prerequisite**: This skill should only be used AFTER the human has tested and committed the code.
**Do NOT run `git commit` directly** — the scripts below handle their own commits for `.trellis/` metadata. You only need to read git history (`git log`, `git status`, `git diff`) and run the Python scripts.

## Record Work Progress
### Step 1: Get Context & Check Tasks
```bash
python3 ./.trellis/scripts/get_context.py --mode record
```
[!] Archive tasks whose work is **actually done** — judge by work status, not the `status` field in task.json:
- Code committed? → Archive it (don't wait for PR)
- All acceptance criteria met? → Archive it
- Don't skip archiving just because `status` still says `planning` or `in_progress`
```bash
python3 ./.trellis/scripts/task.py archive <task-name>
```
### Step 2: One-Click Add Session
```bash
# Method 1: Simple parameters
python3 ./.trellis/scripts/add_session.py \
--title "Session Title" \
--commit "hash1,hash2" \
--summary "Brief summary of what was done"
# Method 2: Pass detailed content via stdin
cat << 'EOF' | python3 ./.trellis/scripts/add_session.py --stdin --title "Title" --commit "hash"
| Feature | Description |

| New API | Added user authentication endpoint |
| Frontend | Updated login form |
**Updated Files**:
- `packages/api/modules/auth/router.ts`
- `apps/web/modules/auth/components/login-form.tsx`
EOF
```
**Auto-completes**:
- [OK] Appends session to journal-N.md
- [OK] Auto-detects line count, creates new file if >2000 lines
- [OK] Auto-detects Branch context (`--branch` override; otherwise Branch = task.json -> current git branch; missing values are omitted gracefully)
- [OK] Updates index.md (Total Sessions +1, Last Active, line stats, history)

### Step 1: Understand Development Workflow
First, read the workflow guide to understand the development process:
```bash
cat .trellis/workflow.md
```
**Follow the instructions in workflow.md** - it contains:
- Core principles (Read Before Write, Follow Standards, etc.)
- File system structure
- Development process
- Best practices
### Step 2: Get Current Context
```bash
python3 ./.trellis/scripts/get_context.py
```
This shows: developer identity, git status, current task (if any), active tasks.
### Step 3: Read Guidelines Index
```bash
python3 ./.trellis/scripts/get_context.py --mode packages
```
This shows available packages and their spec layers. Read the relevant spec indexes:
```bash
cat .trellis/spec/<package>/<layer>/index.md # Package-specific guidelines
cat .trellis/spec/guides/index.md # Thinking guides (always read)
```
> **Important**: The index files are navigation — they list the actual guideline files (e.g., `error-handling.md`, `conventions.md`, `mock-strategies.md`).
> At this step, just read the indexes to understand what's available.
> When you start actual development, you MUST go back and read the specific guideline files relevant to your task, as listed in the index's Pre-Development Checklist.
### Step 4: Report and Ask
Report what you learned and ask: "What would you like to work on?"

## Task Classification
When user describes a task, classify it:
| Type | Criteria | Workflow |
|------|----------|----------|
| **Question** | User asks about code, architecture, or how something works | Answer directly |
| **Trivial Fix** | Typo fix, comment update, single-line change, < 5 minutes | Direct Edit |
| **Simple Task** | Clear goal, 1-2 files, well-defined scope | Quick confirm → Task Workflow |
| **Complex Task** | Vague goal, multiple files, architectural decisions | **Brainstorm → Task Workflow** |
### Decision Rule
> **If in doubt, use Brainstorm + Task Workflow.**
>
> Task Workflow ensures code-specs are injected to the right context, resulting in higher quality code.
> The overhead is minimal, but the benefit is significant.
> **Subtask Decomposition**: If brainstorm reveals multiple independent work items,
> consider creating subtasks using `--parent` flag or `add-subtask` command.
> See the brainstorm skill's Step 8 for details.
---
## Question / Trivial Fix
For questions or trivial fixes, work directly:
1. Answer question or make the fix
2. If code was changed, remind user to run `/finish-work`
---
## Simple Task
For simple, well-defined tasks:
1. Quick confirm: "I understand you want to [goal]. Shall I proceed?"
2. If no, clarify and confirm again
3. **If yes: execute ALL steps below without stopping. Do NOT ask for additional confirmation between steps.**
- Create task directory (Phase 1 Path B, Step 2)
- Write PRD (Step 3)
- Research codebase (Phase 2, Step 5)
- Configure context (Step 6)
- Activate task (Step 7)
- Implement (Phase 3, Step 8)
- Check quality (Step 9)
- Complete (Step 10)
---
## Complex Task - Brainstorm First
For complex or vague tasks, **automatically start the brainstorm process** — do NOT skip directly to implementation.
See `/brainstorm` for the full process. Summary:
1. **Acknowledge and classify** - State your understanding
2. **Create task directory** - Track evolving requirements in `prd.md`
3. **Ask questions one at a time** - Update PRD after each answer
4. **Propose approaches** - For architectural decisions
5. **Confirm final requirements** - Get explicit approval
6. **Proceed to Task Workflow** - With clear requirements in PRD
---
## Task Workflow (Development Tasks)
**Why this workflow?**
- Run a dedicated research pass before coding
- Configure specs in jsonl context files
- Implement using injected context
- Verify with a separate check pass
- Result: Code that follows project conventions automatically
### Overview: Two Entry Points
```
From Brainstorm (Complex Task):
PRD confirmed → Research → Configure Context → Activate → Implement → Check → Complete
From Simple Task:
Confirm → Create Task → Write PRD → Research → Configure Context → Activate → Implement → Check → Complete
```
**Key principle: Research happens AFTER requirements are clear (PRD exists).**
---
### Phase 1: Establish Requirements
#### Path A: From Brainstorm (skip to Phase 2)
PRD and task directory already exist from brainstorm. Skip directly to Phase 2.
#### Path B: From Simple Task
**Step 1: Confirm Understanding** `[AI]`
Quick confirm:
- What is the goal?
- What type of development? (frontend / backend / fullstack)
- Any specific requirements or constraints?
If unclear, ask clarifying questions.
**Step 2: Create Task Directory** `[AI]`
```bash
TASK_DIR=$(python3 ./.trellis/scripts/task.py create "<title>" --slug <name>)
```
**Step 3: Write PRD** `[AI]`
Create `prd.md` in the task directory with:
```markdown
# <Task Title>
## Goal
<What we're trying to achieve>
## Requirements
- <Requirement 1>
- <Requirement 2>
## Acceptance Criteria
- [ ] <Criterion 1>
- [ ] <Criterion 2>
## Technical Notes
<Any technical decisions or constraints>
```
---
### Phase 2: Prepare for Implementation (shared)
> Both paths converge here. PRD and task directory must exist before proceeding.
**Step 4: Code-Spec Depth Check** `[AI]`
If the task touches infra or cross-layer contracts, do not start implementation until code-spec depth is defined.
Trigger this requirement when the change includes any of:
- New or changed command/API signatures
- Database schema or migration changes
- Infra integrations (storage, queue, cache, secrets, env contracts)
- Cross-layer payload transformations
Must-have before proceeding:
- [ ] Target code-spec files to update are identified
- [ ] Concrete contract is defined (signature, fields, env keys)
- [ ] Validation and error matrix is defined
- [ ] At least one Good/Base/Bad case is defined
**Step 5: Research the Codebase** `[AI]`
Based on the confirmed PRD, run a focused research pass and produce:
1. Relevant spec files in `.trellis/spec/`
2. Existing code patterns to follow (2-3 examples)
3. Files that will likely need modification
Use this output format:
```markdown
## Relevant Specs
- <path>: <why it's relevant>
## Code Patterns Found
- <pattern>: <example file path>
## Files to Modify
- <path>: <what change>
```
**Step 6: Configure Context** `[AI]`
Initialize default context:
```bash
python3 ./.trellis/scripts/task.py init-context "$TASK_DIR" <type>
# type: backend | frontend | fullstack
```
Add specs found in your research pass:
```bash
# For each relevant spec and code pattern:
python3 ./.trellis/scripts/task.py add-context "$TASK_DIR" implement "<path>" "<reason>"
python3 ./.trellis/scripts/task.py add-context "$TASK_DIR" check "<path>" "<reason>"
```
**Step 7: Activate Task** `[AI]`
```bash
python3 ./.trellis/scripts/task.py start "$TASK_DIR"
```
This sets `.current-task` so hooks can inject context.
---
### Phase 3: Execute (shared)
**Step 8: Implement** `[AI]`
Implement the task described in `prd.md`.
- Follow all specs injected into implement context
- Keep changes scoped to requirements
- Run lint and typecheck before finishing
**Step 9: Check Quality** `[AI]`
Run a quality pass against check context:
- Review all code changes against the specs
- Fix issues directly
- Ensure lint and typecheck pass
**Step 10: Complete** `[AI]`
1. Verify lint and typecheck pass
2. Report what was implemented
3. Remind user to:
- Test the changes
- Commit when ready
- Run `/record-session` to record this session
---
## Continuing Existing Task
If `get_context.py` shows a current task:
1. Read the task's `prd.md` to understand the goal
2. Check `task.json` for current status and phase
3. Ask user: "Continue working on <task-name>?"
If yes, resume from the appropriate step (usually Step 7 or 8).

name: update-spec
description: "Captures executable contracts and coding knowledge into .trellis/spec/ documents after implementation, debugging, or design decisions. Enforces code-spec depth for infra and cross-layer changes with mandatory sections for signatures, contracts, validation matrices, and test points. Use when a feature is implemented, a bug is fixed, a design decision is made, a new pattern is discovered, or cross-layer contracts change."

# Update Code-Spec - Capture Executable Contracts
When you learn something valuable (from debugging, implementing, or discussion), use this skill 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.
Required sections for infra/cross-layer specs:
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 template download with giget | Relevant `backend/` or `frontend/` file |
| **Made a design decision** | Used type field + mapping table for extensibility | Relevant code-spec + "Design Decisions" section |
| **Fixed a bug** | Found a subtle issue with error handling | `backend/error-handling.md` |
| **Discovered a pattern** | Found a better way to structure code | Relevant `backend/` or `frontend/` file |
| **Hit a gotcha** | Learned that X must be done before Y | Relevant code-spec + "Common Mistakes" section |
| **Established a convention** | Team agreed on naming pattern | `quality-guidelines.md` |
| **New thinking trigger** | "Don't forget to check X before doing Y" | `guides/*.md` (as a checklist item, not detailed rules) |
**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/
├── backend/ # Backend coding standards
│ ├── index.md # Overview and links
│ └── *.md # Topic-specific guidelines
├── frontend/ # Frontend coding standards
│ ├── 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** | `backend/*.md`, `frontend/*.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 `backend/` or `frontend/`
- "This is **what to consider** before writing" → Put in `guides/`
**Example**:
| Learning | Wrong Location | Correct Location |
|----------|----------------|------------------|
| "Use `reconfigure()` not `TextIOWrapper` for Windows stdout" | ❌ `guides/cross-platform-thinking-guide.md` | ✅ `backend/script-conventions.md` |
| "Remember to check encoding when writing cross-platform code" | ❌ `backend/script-conventions.md` | ✅ `guides/cross-platform-thinking-guide.md` |
**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`.

- [ ] 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?

## Relationship to Other Commands
```
Development Flow:
Learn something → /update-spec → Knowledge captured
↑ ↓
/break-loop ←──────────────────── Future sessions benefit
(deep bug analysis)
```
- `/break-loop` - Analyzes bugs deeply, often reveals spec updates needed
- `/update-spec` - Actually makes the updates (this skill)
- `/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
