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

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
