A development workflow bundle for GitHub-based projects. It covers issue breakdown, issue fixes, commits, releases, code-review fixes, post-merge cleanup, project setup, and Playwright browser tests.

Use it to bootstrap an empty project, diagnose an existing repository setup, break down and resolve GitHub issues, prepare releases, respond to code reviews, and create or debug Playwright end-to-end tests.

It keeps common steps in the development lifecycle in one place instead of requiring separate procedures for each task. It also records project state and checks whether an existing repository's agent setup is connected correctly.

Security

Grade A, and why

dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  "version": "1.0.0",
  "description": "Development lifecycle in one bundle. GitHub workflow — commit-and-push, decompose-issue, resolve-issue, release, cr-fix (unified CodeRabbit + ChatGPT-Codex review loop with autonomous apply/defer/skip judgment and rate-limit fallback), post-merge (branch cleanup + config/wiki integration with a mandatory wiki-lore ingest), state-tracker (spec/issue/PR aggregate over .claude/state/spec.json). Project setup — new (first-day bootstrap: interview, .claude/ scaffold, CLAUDE.md + AGENTS.md with Codex reviewer guidelines, gh repo create) and wiring (14-axis harness diagnostic for an existing repo, read-only until approved). Playwright E2E harness — e2e-setup, e2e-author, e2e-debug wrap Playwright's planner/generator/healer agents; never overwrite an existing playwright.config and degrade gracefully without Playwright.",

What it installs

The manifest is a name and a version. 12 skills travel with it, and installing the plugin installs all of them — 1,774 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
