What's New
The writing-plans skill now records decisions like signatures and test assertions instead of full code, resulting in faster and leaner plans.
Breaking Changes
- Removed plan-document-reviewer-prompt.md file.
- Removed CLAUDE.md file (replaced by AGENTS.md).
New Features
- New 'What a Step Contains' structure defining test, code, and verification steps.
- Self-review mechanism that checks the proportion of the plan length relative to the spec.
Improvements
- Plans are approximately 25% faster and use about 33% fewer tokens.
- Self-review mechanism ensures plans remain focused on design rather than implementation.
Upgrade Notes
Configuration files plan-document-reviewer-prompt.md and CLAUDE.md have been removed and replaced by AGENTS.md. The writing-plans skill now generates plans differently, recording decisions rather than full code, which may require adjustments to downstream processing.
