Cookie Project: Implementable Iteration Commits
The planning phase before any code was written. These 6 commits show the /implementable skill transforming a 95KB monolith into executable session-sized chunks.
3 hours from first commit to implementation start.
Planning Commits (Chronological)
| Date | Commit | Description |
|---|---|---|
| 2026-01-07 11:08 | ff4a5cb | First commit The 95KB PLANNING.md monolith. 2500 lines covering everything from Django config to AI integration. Comprehensive but not executable. |
| 2026-01-07 11:22 | 7ba7f84 | Reorganise into modular phase structure Split monolith into 7 focused phase documents. Added WORKFLOW.md explaining how to use Claude Code with the plans. First major restructure. |
| 2026-01-07 11:56 | 2f20128 | Split Phase 8 into 8A and 8B AI integration was too big for one phase. 8A: infrastructure setup. 8B: feature implementation. Recognised that even phases need subdividing. |
| 2026-01-07 12:18 | 37523a2 | Improve plan structure for Claude Code workflow Split combined frontend phases into separate React and Legacy phases. Added Session Scope tables. Explicit test tasks for larger phases. Now 10 phases. |
| 2026-01-07 13:20 | 688b06e | Add checkpoint sections to all phases "Checkpoint (End of Phase)" sections for quick verification before moving on. Explicit test task added to Phase 5. |
| 2026-01-07 14:10 | f5e7b65 | Add mid-session checkpoints and troubleshooting Final refinement. Verification checkpoints after each session, troubleshooting sections, Phase 8B split into 6 sessions. Ready to implement. |
What Changed
| Iteration | Change |
|---|---|
| 1 -> 2 | Monolith split into 7 phase documents + WORKFLOW.md |
| 2 -> 3 | Phase 8 split into 8A (infra) and 8B (features) |
| 3 -> 4 | Combined phases split (4-5, 6-7 -> 4, 5, 6, 7). Session Scope tables added. |
| 4 -> 5 | Checkpoint sections added to all phases |
| 5 -> 6 | Mid-session checkpoints, troubleshooting sections, Phase 8B expanded to 6 sessions |
Timeline
- 11:08 - First commit (monolith)
- 14:10 - Final planning commit
- 14:28 - Phase 1 Session A begins
The implementable skill doesn't just validate - it iteratively reshapes the plan until every session fits a context window.
