Mined from production, not theory

Every skill in the catalog is derived from real call sites in a shipped codebase — not generic framework docs rephrased. Each skill page cites the evidence.

One plugin, five skills

Install the cogs Claude Code plugin once and all 5 skills activate automatically when your prompt matches their trigger conditions — no manual invocation.

The platform behind them, too

Not using Claude Code? The same patterns ship as typed @cogs/* npm packages — auth, transactional email, React Query, and more.
