# Skill: Creating Expert Generate complete expert structure for a new domain. This is a meta-skill - a tool that builds tools. ## When to Use - Adding new tech to stack (e.g., "postgres-expert" for Postgres database) - Creating domain specialist (e.g., "auth-expert" for authentication patterns) - Splitting existing expert into sub-domains - Expanding beyond the 4 core experts (convex, nextjs, shadcn, vercel) ## Workflow ### 1. Interview User Ask clarifying questions: - **Expert name:** What domain? (kebab-case, e.g., "postgres-expert") - **Domain description:** One-line summary - **Initial knowledge sources:** Docs? Agent files? Existing code? - **Related existing agents:** Build on existing agents? ### 2. Create Directory Structure ```bash mkdir -p .claude/experts/{expert-name}-expert ``` Create three files: - `expertise.yaml` - Mental model (initially low confidence) - `question.md` - Question workflow - `self-improve.md` - Self-improvement workflow ### 3. Generate Expertise File Use template from `.claude/experts/_shared/expertise-schema.yaml`: ```yaml --- expert: "{name}-expert" domain: "{Domain Description}" last_updated: "{current-date}" version: "0.1.0" confidence: "low" ---

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.
