How AgentGuards enforces its guardrails in Claude Code — fully automatic, via hooks, with nothing for you to call. Load this if asked how AgentGuards works, whether you need to screen something yourself, or why no agentguards check_input / authorize_action tools are available.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# AgentGuards — enforced by hooks

This plugin has no MCP server, so there is no `check_input`, `authorize_action`
or `health_check` tool — do not `ToolSearch` for them, they are not installed.

That is not reduced protection. The hooks in `hooks/hooks.json` enforce
deterministically, on every request, whatever the model does:

- **`UserPromptSubmit`** screens every prompt before you see it. A blocked prompt
  never reaches you.
- **`PreToolUse`** authorizes every `Bash` command before it runs: denied, put to
  the user for approval, or left to Claude Code's own permission rules. It never
  approves a command on the user's behalf.
- **`PostToolUse`** scans content from `WebFetch`, `WebSearch`, and any `Bash`
  command that fetches (`curl`, `wget`, `http`, `fetch`, `aria2c` — also behind
  `sudo`, `timeout`, `bash -c`, `$(...)`), redacting or withholding it before you
  read it. `Write`, `Edit` and `MultiEdit` are scanned for vulnerabilities and
  secrets.

Nothing here requires you to call a tool, check a decision, or format a block
message — the hook has already acted by the time you see (or don't see) the
…
