Frequently asked questions
What are Claude Code skills?
Claude Code skills are SKILL.md files — Markdown documents with YAML frontmatter that give Claude Code new slash commands and specialized capabilities. Installing a skill is like giving Claude a domain expert persona for a specific task. Skills live in ~/.claude/skills/ and activate the moment Claude Code starts.
How do I install Claude Code skills?
Manually: download the SKILL.md file, place it in ~/.claude/skills/{skill-name}/SKILL.md, and restart Claude Code. With Pro: one-click install via the ClaudSkills desktop app. Either way, the new command is available in seconds. Full install guide →
How are skills scored and ranked?
Every skill is scored 0–100 by an AI quality reviewer checking five dimensions: completeness of the frontmatter (25%), clarity of the instructions (25%), practical applicability (20%), safety — no prompt injection or destructive defaults (20%), and originality (10%). Only skills scoring 70 or above appear in the public catalog. Skills on this page all score 70 or above, with most at 85+.
Are Claude Code skills safe to install?
Yes. Skills are plain Markdown — not executable code. They give Claude natural-language instructions; the worst a bad skill can do is confuse Claude. The quality scorer also screens for prompt injection patterns. As with any open-source resource, read the file before installing.
What's the difference between Claude skills and MCP servers?
MCP servers are external processes that expose tools and APIs to Claude at runtime — they require configuration, API keys, and a running process. Claude Code skills are lightweight Markdown files that extend Claude's behavior through natural-language instructions alone. Skills require no separate process, no network connection, and no API keys beyond what Claude Code itself needs.
