Details

From the project README
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/-state.json`), and generates a structured update report using `references/templates/changelog-report.md`.

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

Version Detection

Parse patterns from changelog:

  • ## vX.Y.Z or ## X.Y.Z - Version headers
  • ### Breaking Changes - Breaking section
  • ### New Features - Features section
  • ### Bug Fixes - Fixes section

State File

Location: ~/.claude/logs/00-changelog/{date}-state.json
