A curated pack of 24 production-grade engineering skills (structured Markdown workflows) for AI coding agents like Claude Code, Cursor, Codex, and Copilot. It provides eight lifecycle slash commands (/spec, /plan, /build, /test, /review, /webperf, /code-simplify, /ship) that encode senior-engineer workflows, quality gates, and best practices across the software development lifecycle.
Use cases
- make my AI coding agent follow senior-engineer best practices
- write a PRD spec before coding with an AI agent
- get consistent code reviews from Claude Code or Cursor
- run test-driven incremental implementation with an AI agent
- audit web performance and Core Web Vitals with my agent
- harden code against OWASP vulnerabilities via AI agent workflows
- simplify and clean up messy code with an AI assistant
- automate the full define-to-ship development lifecycle with slash commands
When to choose
- you use Claude Code, Cursor, Codex, Copilot, Cline, or any agent that accepts Markdown instructions and want structured engineering workflows
- you want consistent quality gates for spec, build, test, review, and ship phases
- you prefer installing individual skills or the whole pack via the open skills CLI
When to avoid
- you need executable tooling or a runtime library rather than Markdown workflow instructions
- your agent cannot read Markdown rules or skills files
- you want opinion-free, minimal prompting without prescribed processes
