# 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."
|
|
|
|
**Context:** This should be run in a dedicated worktree (created by brainstorming skill).
|
|
|
|
**Save plans to:** `docs/plans/YYYY-MM-DD-<feature-name>.md`
|
|
|
|
## 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:**
|
|
|
|
```markdown
|
|
# [Feature Name] Implementation Plan
|
|
|
|
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers: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
|
|
|
|
```markdown
|
|
### 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
|
|
|
|
## Execution Handoff
|
|
|
|
After saving the plan, present execution options:
|
|
|
|
```
|
|
Plan complete and saved to `docs/plans/${filename}.md`.
|
|
|
|
## Recommended Next Step: /cc:parse-plan
|
|
|
|
Decompose this plan into parallel task files. This enables:
|
|
- Up to 2 tasks executing concurrently per batch
|
|
- ~40% faster execution for parallelizable plans
|
|
- 90% context reduction per task
|
|
|
|
**Best for:** Plans with 4+ tasks
|
|
|
|
## Alternative: Execute Without Decomposition
|
|
|
|
Use sequential execution via subagent-driven-development.
|
|
- Best for simple plans (1-3 tasks)
|
|
- Simpler flow, no decomposition overhead
|
|
- One task at a time
|
|
|
|
## Important
|
|
|
|
Decomposition is **REQUIRED** for parallel execution.
|
|
Always decompose plans with 4+ tasks to enable parallel-subagent-driven-development.
|
|

|
|
|
|
Which approach?
|
|
A) Decompose plan (/cc:parse-plan) - Recommended
|
|
B) Execute sequentially without decomposition
|
|
C) Exit (run manually later)
|
|
```
|
|
|
|
**If user chooses A:**
|
|
- Invoke `decomposing-plans` skill
|
|
- Proceed with decomposition workflow
|
|
|
|
**If user chooses B:**
|
|
- Invoke `subagent-driven-development` skill
|
|
- Execute tasks sequentially from monolithic plan
|
|
|
|
**If user chooses C:**
|
|
- Exit workflow
|
|
- User can run `/cc:parse-plan` or execution commands later
