Sweep sub-agent JSONL transcripts for novel learnings and promote the strongest to durable docs. Use when asked to 'mine transcripts', 'sweep for learnings', 'extract learnings from transcripts', 'what did agents learn', 'harvest session insights', or at the end of any multi-agent session.

Instrument a frontend with version fingerprinting (meta tag + /__version endpoint) so LLM-based testing can verify the correct build is deployed before walking. Use when asked to 'add version check', 'deploy verification', 'instrument version', 'add build fingerprint', 'deploy-check', or before running ux-walker on a deploy.

Walk UX story catalog through a real browser, testing each journey for correctness, visual quality, and UX excellence. Auto-fixes small issues, files GitHub issues for larger ones.

This skill should be used when the user asks to "walk the issues", "work through github issues", "groom and implement issues", "tackle the issue backlog", "start the issue loop", "go through tickets", "work all open issues", "clear the backlog", "process all tickets", or "close out open issues". Orchestrates an end-to-end workflow: groom all open GitHub issues with subagents, then loop through them one-by-one - branching, researching, implementing with swarms, testing, committing, merging, and creating PRs until all issues are complete.

Launch the coordinator — a pure-delegation control plane that plans, delegates, reviews, and learns. Use when asked to 'coordinate', 'plan and delegate', 'run the coordinator', 'use the state machine', 'start a structured session', or 'plan this work'.

Deterministic 7-phase debugging workflow — symptom capture, git archaeology, reproduce with a targeted test, log inspection, hypothesis, fix + green confirmation, regression test + commit. Use when asked to 'debug', 'fix a bug', 'investigate a failure', 'diagnose', 'root cause', or 'why is this broken'.

Post-fix test-coverage analysis. Reviews a just-landed fix, generates targeted unit and regression tests, audits how the bug could have been caught earlier. Use after a fix is merged, when asked to 'add regression tests', 'pay off test debt', 'guard against regression', or 'ensure this doesn't happen again'.

Time-boxed research before adopting a library, API, architecture, or provider. Use when asked to 'research', 'compare options', 'evaluate a library', 'spike on', 'investigate a tool', 'should we use X', or 'what are our options for'. Produces structured findings in docs/research/ with no production code changes.

Scaffold a new repository with GitHub issue templates, PR template, development process docs, TDD workflow, hooks, and CI configuration. Use when asked to 'setup a repo', 'scaffold a project', 'init project structure', 'add github templates', 'setup development process', or 'bootstrap repo'.
