Plugin Scanner
Use HOL's local plugin-scanner when a user asks to inspect an AI agent skill, plugin, MCP server, agent package, or repository before installation or use.
The scanner is shipped by the open-source plugin-scanner Python distribution. It is built from the same HOL Guard source repository, but it is intentionally packaged separately from the hol-guard runtime CLI. Scanning runs locally and does not require Guard Cloud.
When to use this skill
Use this skill when the user asks to:
- scan or audit a
SKILL.mdbefore installing it; - inspect an MCP server or agent plugin for security risks;
- check a third-party agent repository before trusting it;
- look for prompt injection, credential exposure, unsafe commands, or suspicious package/install behavior;
- validate a skill/plugin repository in CI or before publishing it.
Safety rules
- Never execute code from the target repository just to scan it.
- Never run its install scripts, package lifecycle hooks, or arbitrary shell commands.
- Never read
.envfiles, credential stores, private keys, or unrelated user secrets. - Prefer scanning a local path or a repository the user has already chosen to inspect.
- Treat scanner findings as security evidence, not a guarantee that a package is safe.
- Ask before installing
plugin-scannerif the command is not already available.
Workflow
1. Check for the scanner
command -v plugin-scanner
If it is not installed, explain that plugin-scanner is a separate open-source CLI distribution from the HOL Guard repository and, with user approval, install it in an isolated CLI environment:
pipx install plugin-scanner
Do not assume an existing hol-guard installation also provides the plugin-scanner command. If pipx is unavailable, point the user to the plugin-scanner installation instructions rather than silently changing their Python environment.
2. Scan the target without executing it
For a repository or directory:
plugin-scanner scan PATH --format markdown
For machine-readable results:
plugin-scanner scan PATH --format json
For Agent Skill / plugin structure validation:
plugin-scanner lint PATH
plugin-scanner verify PATH
Use the narrowest target path that contains the material the user asked to inspect.
3. Interpret findings
Summarize:
- the target that was scanned;
- the highest severity finding;
- concrete files/rules involved;
- whether the scanner found prompt-injection, secret/exfiltration, command-execution, dependency/install, or MCP-specific risks;
- the recommended next action.
Do not claim "safe" solely because no finding was returned. Say that no covered issue was detected by the current scan.
Common prompts
- "Scan this skill before I install it."
- "Check this MCP server for prompt injection or suspicious commands."
- "Audit this agent plugin repository."
- "Verify this SKILL.md and tell me what is risky."
- "Run a security check on this AI tool before we add it to our project."

The scanner is shipped by the open-source `plugin-scanner` Python distribution. It is built from the same HOL Guard source repository, but it is intentionally packaged separately from the `hol-guard` runtime CLI. Scanning runs locally and does not require Guard Cloud. ## When to use this skill Use this skill when the user asks to: - scan or audit a `SKILL.md` before installing it; - inspect an MCP server or agent plugin for security risks; - check a third-party agent repository before trusting it; - look for prompt injection, credential exposure, unsafe commands, or suspicious package/install behavior; - validate a skill/plugin repository in CI or before publishing it. ## Safety rules - Never execute code from the target repository just to scan it. - Never run its install scripts, package lifecycle hooks, or arbitrary shell commands. - Never read `.env` files, credential stores, private keys, or unrelated user secrets. - Prefer scanning a local path or a repository the user has already chosen to inspect. - Treat scanner findings as security evidence, not a guarantee that a package is safe. - Ask before installing `plugin-scanner` if the command is not already available. ## Workflow ### 1.
