Question: "Which implementation plan should I execute?"

  - [list any plan directories you find in docs/implementation-plans/]
  - "Let me provide the path"

The header includes the title (`# [Phase Title]`) and `**Goal:**` line. Extract the title for the task entry.

The grep output shows the task structure, e.g.:

Examples of headers you might see:
- `# Document Infrastructure Implementation Plan` — Phase 1 implied
- `# Phase 4: Link Resolution` — Phase number explicit

**Check for implementation guidance:**

After discovering phases, check if `.ed3d/implementation-plan-guidance.md` exists in the project root:

```bash

If the file exists, note its **absolute path** for use during code reviews. If it doesn't exist, proceed without it—do not pass a nonexistent path to reviewers.

**Check for test requirements:**

Check if `test-requirements.md` exists in the plan directory:

```bash

If the file exists, note its **absolute path** for use during final review. The test requirements document specifies what automated tests must exist for each acceptance criterion.

Write the test plan content to `docs/test-plans/[impl-plan-dir-name].md`, then commit:

```bash
git add docs/test-plans/[impl-plan-dir-name].md
git commit -m "docs: add test plan for [feature name]"

--- Phase 1 ---

[Mark 1a in_progress, read phase_01.md]
→ Contains 2 tasks: project setup, config files

[Mark 1a complete, 1b in_progress]

[Dispatch task-implementor-fast for Task 1]
→ Created package.json, tsconfig.json.

[Dispatch task-implementor-fast for Task 2]
→ Created config files. Build succeeds.

[Mark 1b complete, 1c in_progress]

[Use requesting-code-review skill for phase 1]
→ Zero issues.

[Mark 1c complete]

--- Phase 2 ---

[Mark 2a in_progress, read phase_02.md]
→ Contains 3 tasks: types, service, tests

[Mark 2a complete, 2b in_progress]

[Execute all 3 tasks...]

[Mark 2b complete, 2c in_progress]

[Use requesting-code-review skill for phase 2]
→ Important: 1, Minor: 1
→ Dispatch bug-fixer, re-review
→ Zero issues.

[Mark 2c complete]

--- Phase 3 ---

[Similar pattern...]

--- Finalize ---

[Invoke project-claude-librarian subagent]
→ Updated CLAUDE.md.

[Use requesting-code-review skill for final review]
