Use for an adversarial red-team / blue-team / auditor review of an AI agent's CONFIG + behaviour (rules, skills, MCP, hooks, permissions) — attack-chain → defensive-gap list, not a code audit.

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

# agent-security-review

A holistic, adversarial review of an **agent's configuration and behaviour** —
the trust anchor, not the application code. Where [`threat-modeling`](../threat-modeling/SKILL.md)
models a code change and [`security-audit`](../security-audit/SKILL.md) hunts
code vulnerabilities, this skill asks: *given this assembled agent config
(rules, skills, MCP servers, hooks, permissions, memory), how would an attacker
turn it against its owner, and what defensive gap lets them?*

Pairs the static signal from [`/security-audit-config`](../../agent-src/commands/) with an
adversarial three-lens pass. Output is **decision support** — surface the
trade-off, name the gap; the human decides.

## When to use

- A consumer asks "is my agent setup safe / could this be weaponised".
- Before trusting a third-party skill pack, MCP server, or rules file.
- Periodic posture review of a fleet's agent config.
- Any `D`/`F` category from `/security-audit-config` that warrants depth.

## Procedure

### 1. Inventory + inspect the attack surface

Inspect the config the agent actually loads and check each surface in turn:
instruction files (CLAUDE.md /

How to install

The exact contents, by fingerprint
mdr add event4u-app/agent-config/agent-security-review@sha256:97c9a010c330494e

The line at the top of this page pins the label git:20260727.51710ca, 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.
