Change Logger — quick diffs

Produce a dated, analogy-rich markdown entry in CHANGELOG.md so reviewers (human or model) see what moved without wading through raw diffs.

Main use case

• Default: include committed changes since the last base marker in CHANGELOG.md plus current working tree edits, then record a new base marker.
• Optional: limit to staged only or a specific commit range (e.g., main..HEAD).
• Output: grouped by the first two path segments (e.g., skills/brave-search) with A/M/D/R counts and short analogies.

Commands

• Show help: ./scripts/change-logger.ts --help
• Working tree (staged + unstaged): ./scripts/change-logger.ts
• Staged only: ./scripts/change-logger.ts --staged
• Commit range: ./scripts/change-logger.ts --range main..HEAD
• Custom section title: ./scripts/change-logger.ts --title "Landing page polish"

Notes

• Requires git in PATH and a repository context.
• Ignored dirs follow git defaults; handles renames via git diff output.
• Writes/updates CHANGELOG.md at the repo root with dated sections and analogies; ideal for PRs, oracle prompts, or release notes.
• The base commit marker is stored in each new changelog section and used on subsequent runs to avoid re-listing old commits.
