Writing Plans

Overview

Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.

Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.

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

Save plans to: The active conductor track directory: conductor/tracks/{track_id}/plan.md If no conductor track exists, create one first using the /orchestrator-supaconductor:new-track flow.

Bite-Sized 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 Document Header

Every plan MUST start with this header:

# [Feature Name] Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use orchestrator-supaconductor:executing-plans 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**

```python
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**

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

Remember

• 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

Conductor Integration

This skill is part of the Conductor workflow. All plans are saved to the active track directory.

When invoked by the Conductor orchestrator (with --track-dir and --spec parameters):

• Read spec from --spec path
• Read project context from conductor/product.md, conductor/tech-stack.md
• Save plan to {--track-dir}/plan.md
• Include DAG section for parallel execution
• Update track's metadata.json checkpoint to PLAN: PASSED
• Return control to orchestrator — do NOT start execution

When invoked standalone (no parameters):

• Look for the active track in conductor/tracks.md
• Read its spec.md for requirements
• Save plan to conductor/tracks/{track_id}/plan.md
• Update track's metadata.json checkpoint to PLAN: PASSED
• After saving, announce the plan summary and HALT — do NOT start execution
• The user should run /orchestrator-supaconductor:implement or /orchestrator-supaconductor:go to execute
