Rust Audit

Auditor and auto-fixer for AI-generated Rust code: stubs, demo code, fake tests, fakes/mocks leaking into production, panic/unsafe misuse, swallowed errors, async pitfalls, and fake / hallucinated / typosquatted dependencies (slopsquatting).

Python 3.11+ stdlib only — no dependencies. English output.

Install

pipx install rust-audit      # or: pip install rust-audit
rust-audit selftest          # prints `selftest PASS`

From PyPI as rust-audit, whose wheel installs both commands: rust-audit and rustaudit run the same module. There is no separate one-word project on PyPI — it answers "This project name is too similar to an existing project" — so the spelling is served by this package's own entry point. Nothing is fetched or executed at install time, and the wheel carries the same rust_audit.py as the signed release asset — so the verify-before-use chain below still applies to the script you download.

The wheel's digest is attested by the workflow that built it, so you can check where it came from before running it:

gh attestation verify rust_audit-*-py3-none-any.whl -R Doken-Tokuyama/Rust-Audit

Quick start

# 0) verify before use — check the exact audited bytes before executing them
#    (key pin -> SSH signature -> checksum -> tag identity) and proceed only
#    on VERIFIED (exit 0); see SECURITY.md for the pinned key and the chain
scripts/verify_release.sh v0.2.5 ./rust_audit.py

python3 scripts/rust_audit.py selftest
python3 scripts/rust_audit.py scan  <rust-project> --format terminal,md,json,sarif --fail-on high
python3 scripts/rust_audit.py fix   <rust-project> --dry-run
python3 scripts/rust_audit.py cargo <rust-project> --deep --supply-chain

Exit codes: 0 clean · 1 findings at/above --fail-on · 2 execution error. Every run writes a not-executed report (report/not-executed-<date>.md) listing the checks that could not run and how to enable them — read it before calling an audit complete.

As a Freebuff agent skill: install rust-audit into Freebuff on any machine by following docs/freebuff-skill-install.md.

Tests

Production E2E suite: the real CLI audited against real Rust workspaces (BurntSushi/ripgrep and tokio-rs/tokio, each pinned by commit — no demo fixtures), with per-project goldens. Needs network to fetch the pinned workspaces, Python 3.11+ and pytest in a venv:

python3 -m venv .venv && .venv/bin/pip install pytest
.venv/bin/python -m pytest tests/

See SKILL.md for the rule catalog (R01–R21), the auto-fix policy, the CI templates and the honest limitations.

Security

The trust model is explicit: what executes (literal cargo argv, no shell), what leaves the machine (opt-in --online registry/OSV lookups only) and what writes to disk (transactional fix). See SECURITY.md — including the notes for static skill auditors.

Release assets are SSH-signed: an install can verify it has the exact audited rust_audit.py with preinstalled ssh-keygen alone — commands and the pinned signing key live in SECURITY.md.

Hardened scanners can enforce the static-only contract in code: every subcommand accepts --no-exec, under which process creation is impossible (one guarded entry point refuses every spawn) and each check that would have executed is recorded as skipped in the not-executed report.
