# Agent Expert Creation Skill Create specialized agent experts that learn and maintain domain knowledge through the Act-Learn-Reuse pattern. ## Core Problem Solved > "The massive problem with agents is this. Your agents forget. And that means your agents don't learn." Generic agents execute and forget. Agent experts execute and learn by maintaining expertise files (mental models) that sync with the codebase. ## When to Use - Repeated complex tasks in a domain (database, billing, WebSocket) - High-risk systems where mistakes cascade (security, payments) - Rapidly evolving code that needs tracked mental models - Need consistent domain expertise across sessions - Building plan-build-improve automation cycles ## The Act-Learn-Reuse Pattern ```text ┌─────────────────────────────────────────────────────────────┐ │ ACT-LEARN-REUSE CYCLE │ ├─────────────────────────────────────────────────────────────┤ │ │ │ ACT ──────────► LEARN ──────────► REUSE │ │ │ │ │ │ │ │ │ │ │ │ ▼ ▼ ▼ │ │ Take useful Update expertise Read expertise │ │ action file via file FIRST on │ │ (build, fix) self-improve next execution │ │ prompt │ │ │ └─────────────────────────────────────────────────────────────┘ ``` | St

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill agent-expert-creation-melodic-software-claude-code-plugins --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
