Generate Tdd Tasks

Generate TDD Tasks

Core Process

Step 1: Project Detection

Detect and list the project's conventions before generating tasks:

1. Test command — Check config files. Ruby: bundle exec rspec if Gemfile has rspec. Python: pytest. JS/TS: npm test / yarn test. Rust: cargo test. Go: go test ./....
2. Source directory — lib/ (Ruby), src/ (most other languages).
3. Test directory — spec/ (RSpec), test/ (Minitest/pytest/unittest/Go standard).
4. Doc tool — YARD (Ruby), JSDoc (JS/TS), rustdoc (Rust), pydoc (Python).
5. Language/framework — Detect from Gemfile, Cargo.toml, package.json, go.mod, pyproject.toml.

Step 2: Requirements Analysis

Break down the feature/PRD into implementation tasks:

1. Identify user-visible behaviors — capabilities, endpoints, data flows.
2. Apply first-slice heuristics:
   • Web app / API: Start with request/integration test.
   • Service / domain logic: Start with service or unit test.
   • Background job: Start with worker test.
   • External integration: Start with client layer test.
   • Library / SDK: Start with public API test.
3. Group related behaviors into parent tasks with TDD quadruplets.

Step 3: Generate Task List

Create tasks/tasks-<feature-name>.md with the required structure below.

Step 4: Validation Gates (HARD-GATE)

Before saving output, every gate below MUST pass:

1. Task 0.0 is the feature branch creation — mandatory, must be first.
2. Every implementation task uses the TDD quadruplet (RED → fail → GREEN → pass → REFACTOR).
3. Public API documentation, update existing documentation, and code review tasks are present — do not omit them.
4. Guidance Used section explains what conventions/guides/skills drove the breakdown.
5. Relevant Files section lists detected source and test directories and key files.
6. Output is saved to tasks/tasks-<feature-name>.md unless user specifies otherwise.

If any gate fails, correct the task list before saving.

Task List Template

# Task List: <Feature Name>

Based on: <prd or requirement source>

## Guidance Used

- <Skill or convention that guided this breakdown — e.g. tdd-process, test-planning-process, project conventions>
- <Specific decisions: why first slice chosen, why certain boundary selected>

## Relevant Files

- Source directory: `<detected source dir>/`
- Test directory: `<detected test dir>/`
- `<path/to/file.ext>` — <why it's relevant>
- `<path/to/test.ext>` — <test coverage>

## Tasks

- [ ] **0.0 Create feature branch**
  `git checkout -b feature/<feature-name>`

- [ ] **1.0 <Behavior Description> (TDD Quadruplet)**
  - [ ] 1.1 Write failing test for `<behavior>`
        `<test-dir>/path/to/test.ext`
  - [ ] 1.2 Run test — verify failure
        `<test-command>` → expected failure
  - [ ] 1.3 Implement minimal code to pass
        `<source-dir>/path/to/impl.ext`
  - [ ] 1.4 Run test — verify success
        `<test-command>` → green
  - [ ] 1.5 REFACTOR: Clean up implementation

- [ ] **2.0 <Next Behavior> (TDD Quadruplet)**
  - [ ] 2.1 ... (same pattern as 1.1-1.5)

- [ ] **3.0 <Next Behavior> (TDD Quadruplet)**
  - [ ] 3.1 ...

- [ ] **N.0 Public API Documentation**
  - [ ] N.1 Add YARD/JSDoc/rustdoc/pydoc comments to all new public methods
        `<source-dir>/path/to/file.ext`

- [ ] **N+1.0 Update Existing Documentation**
  - [ ] N+1.1 Update README or relevant docs for any changed behavior

- [ ] **N+2.0 Code Review**
  - [ ] N+2.1 Self-review diff before creating PR
  - [ ] N+2.2 Run full test suite — all green
