Write comprehensive implementation plans assuming the engineer has zero context for the codebase. Document everything they need: which files to touch, code, testing, how to verify. Give them bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.

Announce at start: "I'm using the use-plan-create skill to create the implementation plan."

Context: Run in a dedicated worktree (created by use-brainstorm skill).

Save plans to: docs/plans/YYYY-MM-DD-<feature-name>.md

Task Granularity

Each step is one action (2-5 minutes):

• "Write the failing test" - step
• "Run it to make sure it fails" - step
• "Implement the minimal code to make the test pass" - step
• "Run the tests and make sure they pass" - step
• "Commit" - step

Plan Header

Every plan MUST start with:

# [Feature Name] Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use autonome:use-plan-execute to implement this plan task-by-task.

**Goal:** [One sentence describing what this builds]

**Architecture:** [2-3 sentences about approach]

**Tech Stack:** [Key technologies/libraries]

---

Task Structure

### Task N: [Component Name]

**Files:**
- Create: `exact/path/to/file.py`
- Modify: `exact/path/to/existing.py:123-145`
- Test: `tests/exact/path/to/test.py`

**Step 1: Write the failing test**

```python
def test_specific_behavior():
    result = function(input)
    assert result == expected

Step 2: Run test to verify it fails

Run: pytest tests/path/test.py::test_name -v Expected: FAIL with "function not defined"

Step 3: Write minimal implementation

def function(input):
    return expected

Step 4: Run test to verify it passes

Run: pytest tests/path/test.py::test_name -v Expected: PASS

Step 5: Commit

git add tests/path/test.py src/path/file.py
git commit -m "feat: add specific feature"

# Key Rules

- Exact file paths always
- Complete code in plan (not "add validation")
- Exact commands with expected output
- Reference relevant skills with @ syntax
- DRY, YAGNI, TDD, frequent commits

# Execution Handoff

After saving the plan, offer execution choice:

**"Plan complete and saved to `docs/plans/<filename>.md`. Two execution options:**

**1. Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration

**2. Parallel Session (separate)** - Open new session with plan-execute, batch execution with checkpoints

**Which approach?"**

**If Subagent-Driven chosen:**
- Use autonome:use-subagents-dispatch
- Stay in this session
- Fresh subagent per task + code review

**If Parallel Session chosen:**
- Guide them to open new session in worktree
- New session uses autonome:plan-execute
