Surface open PRs that have genuinely unaddressed review feedback, filtering out CodeRabbit auto-summaries and CI-bot noise. Use before ending a session, when asked "which of my PRs need attention", or to gate a session close on unresolved review threads.
Sync git repository with upstream. Use at the start of a session, when asked to sync, get up to date, check git status, or when working on a stale branch.
Analyze content and generate illustrations via Gemini image API
Brainstorm multiple visual directions for a blog image, generate them in parallel, build a comparison page, and optionally publish as a shareable link (Surge.sh or gist).
Bulk-parallel CLIs โ turn N sequential gh/bd/git/file tool calls into a single fan-out JSON call. Use when the session is about to fire โฅ3 similar sequential calls (gh pr view, bd show, Read of small files, up-to-date diagnose across repos).
Extract durable lessons from a completed Claude session and codify them in the right CLAUDE.md files or skills. Use at the end of a long session, after a bug hunt that surfaced a non-obvious constraint, or when the user asks "what can we learn from this session". Discovers CLAUDE.md files dynamically, routes lessons by generic scope (project / shared conventions / environment / machine-local), enforces neutral voice, and asks for approval before editing.
Read (not generate) images via a subagent so the pixel payload stays out of the parent conversation. Dispatches Haiku by default, escalates to Sonnet/Opus when the caller flags ambiguity or needs load-bearing detail.
Use when the user asks to make a change in a different git repo than the current session's cwd, and wants it done without polluting the current conversation with that repo's context. Typical triggers โ "also fix X in the blog", "delegate this to the dotfiles repo", cross-repo tasks mentioned alongside current work.
