Agent skills for guardrails and AI safety in Claude Code

287 agent skills for guardrails and AI safety in the catalog list Claude Code as a supported host. These are the 15 that rank highest, ordered by adoption, freshness and documentation. ai-coding-agent-guardrails, git-guardrails-claude-code and ai-red-teaming lead the list. Claude Code reads them from .claude/skills/<name>/SKILL.md in the project, or ~/.claude/skills/<name>/ for every project. A skill is a folder with a SKILL.md file; Claude Code loads it when a task matches its description. Every listing links to its source and shows a freshness grade.

How to install in Claude Code

npx skills add <owner>/<repo> --skill <name> -a claude-code

Where it goes: .claude/skills/<name>/SKILL.md in the project, or ~/.claude/skills/<name>/ for every project.

The host's docs describe copying a folder with a SKILL.md into a skills directory; the npx skills command is a third-party shortcut for the same thing.

Each listing page has the exact command for that listing.
