Agent Skill Trust Check
Before you install a third-party agent skill from OpenClaw, an MCP bundle, or a GitHub SKILL.md, run this static analyzer to catch red flags. It scans the description text for risky patterns like shell execution, credential access, remote webhooks, and prompt injection signals, then lists missing provenance details like license or uninstall steps. The marketplace-safe stdin runner needs zero filesystem or network permissions, so it can run in sandboxed environments. It won't execute anything or guarantee runtime safety, but it gives you a structured pre-install checklist before you hand filesystem or API access to an untrusted package.

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.
