44 skills that turn coding agents into a shipping team

What it does It’s a pack of 44 agent skills, organized into six packs (product, ai-shipping, agent-teams, agent-harness, app-stack, work-humanizer), that work in Claude Code, Codex, Cursor, Gemini CLI, OpenCode and Copilot — anything that reads SKILL.md folders. The skills walk a product from idea to paying users: proposal, plan, build, review, release, and running it in production. A /product:start-here command reads where you are and names the next step.

The interesting bit These aren’t hypothetical — the author shipped three live products with coding agents (AskOne, Staygreen, AFK Pilot) and the skills’ dated case studies come from that. The workflow also bakes in separation of powers: one session coordinates, another builds, and a different session reviews every change, because no session should review its own work.

Key highlights

• Covers the unglamorous production half: supabase-production, clerk-production, saas-authorization, transactional-email, uptime-monitoring.
• Multi-agent aware: skills for delegating between Claude Code, Codex and others, with handover and retro commands.
• Companion pm-skills covers discovery and go-to-market; this collection takes over at building and shipping.
• Skills are self-contained folders — copyable by hand into any agent’s skill directory.
• Free, MIT licensed, with tests running in CI.

Caveats

• Claude Code and Codex read skills from different places, so multi-agent setups mean installing in each one — the README is upfront about this friction.
• The README documents a real Claude Code plugin-update bug with multiple worktrees, which is honest but a reminder the tooling around this is still young.
• Five skills overlap with pm-skills and load twice if you keep both; you have to manage that yourself.

Verdict Worth a look if you’re a PM, founder or engineer shipping an actual product with agents and want a battle-tested process instead of improvising one. If you just want a code-completion copilot, this is a different animal.
