Performs comprehensive C/C++ security review for memory corruption, integer overflows, race conditions, and platform-specific vulnerabilities. Use when auditing native C/C++ applications, reviewing daemons or services for memory safety, or hunting integer overflow / use-after-free / race conditions in userspace code.
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
# C/C++ Security Review Resolve four parameters, make one `Workflow` call, return the report. The workflow owns concurrency, retries and result collection. **Use for:** native C/C++ userspace — memory safety, integer overflow, races, type confusion, Linux/macOS daemons, Windows services. **Not for:** kernel drivers or modules; managed languages (Java, C#, Python, Go, Rust); embedded or bare-metal code with no libc. ## Phase 0 — Parameters Parse any free text on the invocation line (`flamenco only`, `high severity only`, `use haiku`) and pre-fill what it implies. Then make **one** `AskUserQuestion` call for whatever is still unresolved. Never silently default a required parameter. | Parameter | Values | Inferring it from the invocation | |---|---|---| | `threat_model` | `REMOTE` / `LOCAL_UNPRIVILEGED` / `BOTH` | "remote", "network", "attacker" → `REMOTE`; "local", "unprivileged" → `LOCAL_UNPRIVILEGED`; otherwise ask | | `worker_model` | `haiku` / `sonnet` / `opus` / `inherit` | An explicit model name. Otherwise ask. `inherit` uses the session model | …

How to install
mdr add trailofbits/skills/c-review@sha256:3fc2fc7f3dba9decThe line at the top of this page pins the label git:20260824.311a784, 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.
