Agent Skill Trust Check
Use this skill before installing a third-party agent skill, SKILL.md package, MCP-linked skill, or marketplace listing.
What This Skill Does
- Reads a public or local skill description before install.
- Flags patterns that deserve review: shell execution, destructive commands, secrets, wallet/payment actions, network output, persistence, and prompt-boundary issues.
- Separates basic provenance signals from risky behavior signals.
- Produces a patch order that a maintainer can resolve before the skill is trusted.
When To Use
Use this when an agent is about to install or recommend a skill from:
- OpenClaw, Hermes, or ClawHub-style marketplaces.
- Claude Code, Codex, Cursor, Windsurf, or Gemini skill directories.
- MCP-linked skill bundles.
- GitHub repositories that include a
SKILL.md, tool manifest, or install script.
Run From The Public Repo
git clone https://github.com/TateLyman/agent-skill-trust-check.git
cd agent-skill-trust-check
npm run check
node bin/agent-skill-trust-check.js ./SKILL.md
Marketplace-safe stdin mode:
node bin/agent-skill-trust-check-stdin.js < ./SKILL.md
For JSON output:
node bin/agent-skill-trust-check.js ./SKILL.md --json
npm command:
npx --yes agent-skill-trust-check ./SKILL.md --json
Review Rules
Before installation, check:
- Does the skill run shell commands, package installers, or process-spawn APIs?
- Does it read secrets, environment variables, wallet data, credentials, cookies, or private keys?
- Does it send content to remote URLs or webhooks?
- Does it create persistent background jobs?
- Does it ask the agent to ignore or override higher-priority instructions?
- Does it document source, license, version, tests, permissions, and uninstall steps?
Boundaries
This is a static pre-install check. The marketplace-safe runner reads only stdin and returns JSON. The local CLI can also read a local path or a public GitHub/raw/Gist URL when run from the repository checkout. Neither mode executes the target skill or proves the runtime is safe.
