global-agent-guardrails from davidondrej/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add davidondrej/skills/global-agent-guardrails@git:20261018.eaed515

Configure the shared guard against catastrophic shell commands in local AI agents. Use when changing block patterns, adding an agent or machine, or investigating why a command was or wasn't blocked.

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

# Global Agent Guardrails

Block catastrophic shell commands before execution. One patterns file feeds a shared hook script or native adapter for each agent. This guards against accidents, not malicious agents (obfuscation like `python -c "shutil.rmtree(...)"` can slip past regex).

[Cloudroom](https://www.cloudroom.dev/security) ships a built-in Command Guard based on this one, on by default.

## File map

The setup consists of a shared pattern list, a guard script, a test suite, and agent-specific adapters. Keep those in the appropriate user-level configuration locations for your tools.

## Check installation

Confirm the shared guard and patterns are present, then run the test suite; it should report no failures.

If missing, rebuild from the wiring documentation in the project documentation.

## Add or tune a pattern

1. Edit the shared patterns file. Write POSIX ERE (`grep -E`). Use `[[:space:]]`, never `\s` — adapters may convert `[:space:]` to `\s` for JS/Python and compile in multiline mode.
2. Add block and allow cases to the test suite, then run it; all must pass.
3. Verify the new pattern compiles in each adapter's regex engine.

How to install

The exact contents, by fingerprint
mdr add davidondrej/skills/global-agent-guardrails@sha256:82b1d277723d972d

The line at the top of this page pins the label git:20261018.eaed515, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
