Using AI Better, Step Two: Write the Skill Before Execution

The author proposes writing a Skill before asking AI to execute a task; each Skill should include three elements—success criteria, observed pitfalls, and deterministic tools—and can be organized through index.md plus AGENTS.md or CLAUDE.md for reuse.

Why it matters: HKR-H/K/R pass via a concrete Skill-first workflow and reusable agent practice. No model release, product capability, or experiment numbers, so it sits at the featured threshold.
