ABOUTME: Manages lifecycle: /spec.plan -> /spec.refine -> /spec.tasks -> /spec.run
Spec-Driven Development
Iterative feature development ensuring zero ambiguity before execution.
Quick Reference
| Command | Purpose |
|---|---|
/spec.plan <intent> |
Create spec from feature description |
/spec.refine [section] |
Improve spec with research |
/spec.clarify <response> |
Answer clarification questions |
/spec.tasks |
Break spec into executable tasks |
/spec.run [task#] |
Execute tasks with TDD |
Core Principle
Iterate until clarity: No task execution begins until ALL questions are resolved. Claude must be able to execute without interruptions.
Phase 1: /spec.plan - Create Specification
Trigger: /spec.plan <description> or "I want to build/add X"
Workflow
- Check
specs/folder - create if missing - Generate spec file:
specs/{feature-slug}.md - Fill initial sections from user intent
- Generate clarifying questions
- STOP and present questions
Output
Created: specs/feature-name.md (DRAFT)
Questions requiring clarification:
1. [Question about scope]
2. [Question about behavior]
Use /spec.clarify to answer.
Phase 2: /spec.refine - Research & Improve
Trigger: /spec.refine [section]
Workflow
- Load active DRAFT spec
- Search codebase for similar patterns
- Update Technical Strategy
- Re-evaluate clarity
- If questions remain: STOP and present
Phase 3: /spec.clarify - Answer Questions
Trigger: /spec.clarify <response>
Example
User: /spec.clarify Q1: OAuth2 with Google only. Q2: Admin can also delete.
Updated specs/auth-system.md:
- Added OAuth2/Google to Technical Strategy
- Updated permissions
Remaining questions: None
Spec ready. Use /spec.tasks
Phase 4: /spec.tasks - Task Breakdown
Trigger: /spec.tasks
Prerequisites
- Active spec must be DRAFT or APPROVED
- "Open Questions" section must be empty
- If questions exist: STOP → /spec.clarify
Task Granularity
Tasks should be high-level logical units:
- "Implement authentication middleware"
- "Create user model and repository"
- "Add API endpoints for user CRUD"
TDD cycle happens WITHIN each task during /spec.run.
Phase 5: /spec.run - Execute Tasks
Trigger: /spec.run [task#]
Prerequisites
- Task file must exist:
specs/{feature}.tasks.md - If no task file: STOP → /spec.tasks
Execution Rules
- TDD for each task: Red → Green → Refactor → Commit
- Invoke language skills:
/typescriptfor .ts files - Respect hooks: Pre-commit must pass
- Mark completed in task file

Ecommerce-Specific Scopes
When creating specs, consider these modules:
| Module | Files | Considerations |
|---|---|---|
| Auth | apps/backend/src/modules/auth/ |
JWT, sessions, rate limits |
| Catalog | apps/backend/src/modules/catalog/ |
Redis caching |
| Cart | Frontend hooks + Backend | Session persistence |
| Orders | apps/backend/src/modules/orders/ |
Transactions |
| Checkout | apps/frontend/src/app/checkout/ |
Payment flow |
Templates
See references/templates.md for:
- Spec file template
- Task file template
- specs/README.md template
Session Resume
On context compaction:
- Check
specs/for files with statusIN_PROGRESS - Check
.tasks.mdfiles for unchecked items - Report: "Found in-progress spec: X with Y tasks remaining"
- Ask: "Continue with /spec.run?"
