<objective> Fetches the official Claude Code changelog via the harness CLI's `changelog` command (ported from the old `fetch-changelog`, WebFetch on `code.claude.com/docs/en/changelog.md` as manual fallback), parses version headers and per-version changes (features/fixes/breaking), compares against the last known version recorded in the state file (`~/.claude/logs/00-changelog/<date>-state.json`), and generates a structured update report using `references/templates/changelog-report.md`. </objective>

Changelog Scan Skill

Overview

Fetches and analyzes the official Claude Code changelog to detect new versions and changes.

Data Sources

| Source | URL | Method | |--------|-----|--------| | Changelog | code.claude.com/docs/en/changelog.md | WebFetch | | Docs Index | code.claude.com/docs/llms.txt | WebFetch | | Hooks Ref | code.claude.com/docs/en/hooks.md | WebFetch | | Plugins Ref | code.claude.com/docs/en/plugins-reference.md | WebFetch | | CLI Ref | code.claude.com/docs/en/cli-reference.md | WebFetch |

Workflow

1. **Fetch** changelog via the harness CLI (ported from the old `fetch-changelog` into `@fusengine/harness`): `bun ${CLAUDE_PLUGIN_ROOT}/../node_modules/@fusengine/harness/dist/cli/bin.mjs changelog` It fetches `code.claude.com/docs/en/changelog.md`, parses versions (current MDX `<Update label="X.Y.Z">` format + legacy `## vX.Y.Z` fallback), writes state to `~/.claude/logs/00-changelog/<date>-state.json`, and prints JSON `{latest, new_since_last_check, recent_versions}`. WebFetch on the same URL is the manual fallback. 2. **Parse** version numbers and release dates 3. **Extract** changes per version (features, fixes, breaking) 4. **Compare** with last known version from state file 5. **Generate** report using templates/changelog-report.md
