Review A Skill

Goal

Evaluate a single skill's quality, relevance, and safety before it enters or stays in a library.

Guardrails

Always use --format json for machine-readable output in automated pipelines.
Always use --fields to limit output size when inspecting catalog entries.
Always use --dry-run before curating or removing a skill.
Never remove a skill without first checking if other skills depend on it via info --format json dependencies.

Workflow

Preview the skill content to check for quality and safety.

npx ai-agent-skills preview <skill-name>

The preview command sanitizes content — if it flags sanitization, investigate before proceeding.

Inspect the catalog entry for metadata completeness.

npx ai-agent-skills info <skill-name> --format json --fields name,description,tags,collections,dependencies

Validate the skill's SKILL.md structure.

npx ai-agent-skills validate <skill-name>

If the skill needs curation (notes, collections, verification):

npx ai-agent-skills curate <skill-name> --notes "Reviewed: solid patterns" --verify --dry-run
npx ai-agent-skills curate <skill-name> --notes "Reviewed: solid patterns" --verify

If the skill should be removed:

npx ai-agent-skills curate <skill-name> --remove --dry-run
npx ai-agent-skills curate <skill-name> --remove --yes

Decision Criteria

Keep: Clear description, valid frontmatter, useful to the library's audience, no injection patterns.
Curate: Needs better whyHere, collection placement, or verification status.
Remove: Duplicate, outdated, broken source, or contains suspicious content.

Gotchas

The preview command only works for vendored (house) skills. Upstream skills show description and whyHere only.
The validate command checks frontmatter structure but not content quality — that requires human or agent judgment.
Removing a skill that other skills depend on will break the dependency graph. Always check dependencies.usedBy first.

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

Dispatching Parallel Agents

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

How to use it

Copy the folder

Take moizibnyousaf/review-a-skill from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
