addyosmani/agent-skills: Production-grade engineering skills for AI coding agents
An open-source skill pack that encodes senior-engineer workflows, quality gates, and best practices so AI coding agents follow them across define, plan, build, test, review, and ship phases, with 9 slash commands. It installs via npx skills into 70+ agents including Claude Code, Cursor, and Codex, and individual skills can be installed separately.
What this means for indie developers：Indie developers can use it to bring AI coding agents into a disciplined workflow with less rework and better code quality, though per-skill installs lose access to shared reference checklists.
