# Changelog

All notable changes to `@izhimu/pi-caveman` will be documented in this file.

## [0.2.1] - 2026-08-21

### Changed & Improved
- **Prompt Rules Upstream Sync**: Synchronized core compression rules with upstream Caveman v2.2.0 — added anti-expansion guards (no fake broken grammar), verb preservation on equal token cost, and clear external issue/ticket boundaries.
- **Robust Mode Parser**: Added quoted-span disambiguation to prevent quoted text like `"stop caveman"` from triggering deactivation; added punctuation and quote normalization for `/caveman` arguments.
- **Enhanced `caveman-compress`**: Fixed Windows `cp1252` encoding exceptions, improved CommonMark code fence parsing, and preserved original file line endings (CRLF/LF) atomically.
- **Skill Slimming**: Trimmed redundant cloud-dependent and generic workflow skills to reduce initial system prompt index overhead by ~75%.
