agent-skills — Production Skills for AI Coding Agents

Practical Notes

• Quant: start by installing 5–8 skills that cover your highest-frequency tasks (planning, tests, reviews) before importing the full library.
• Quant: track “skill hit rate”: out of 20 tasks, how many used at least one skill file end-to-end?

Make skills composable

Skills work best when they’re small and opinionated:

• One skill = one job (e.g., “plan tasks”, “add tests”, “review PR”).
• Keep inputs explicit (file paths, commands, constraints).
• Make outputs auditable (checklists, diffs, artifacts).

How to roll out without chaos

1. Choose a small set of baseline skills everyone uses.
2. Put them under version control and review changes.
3. Add new skills only when a real workflow needs it.

Avoiding prompt drift

Pin your skill versions in a repo and document the expected behavior. If outcomes change, treat it like a dependency upgrade: evaluate, then roll forward.

FAQ

Q: Do I need Gemini CLI to benefit? A: No. Gemini CLI is one supported install path; any agent that can read instruction files can use the skills.

Q: Should I install everything? A: Start with a small baseline set so behavior is predictable.

Q: How do I measure impact? A: Measure time-to-plan and defect rate before/after introducing skills on the same task type.
