Review a focused trust-boundary or exploit-path change without modifying it. Use when work introduces or materially changes untrusted input, privilege decisions, secret flow, dangerous sinks, or agent and tool capabilities.
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
# Security Review Own concrete trust-boundary and exploit-path analysis, not generic changed-code review. ## Workflow 1. Confirm the diff or audit scope, assets, actors, trust boundaries, and relevant privileges. 2. Trace each material untrusted source through parsing, validation, authorization, and dangerous sinks or persistent side effects. Untrusted sources include user input, files, network responses, environment variables, other services, and, for agent and tool capabilities, model output, fetched pages, and issue or pull request text. 3. For every new or changed entry point that reads or changes a protected resource, confirm an authorization check on that resource, not only authentication, and confirm the tenant scope. Missing authorization is among the most common exploitable defects. Check that an error inside a security check denies access instead of allowing it. 4. Check changed secret handling, command execution, paths and archives, network destinations, authentication, authorization, tenant isolation, logs, plugins, MCP tools, sandboxes, and agent capabilities only where they participate in a concrete path. …

How to install
mdr add yarlson/yarstack/security-review@sha256:d271d3cbf58f312aThe line at the top of this page pins the label git:20261017.2f2e03b, 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.
