code-audit SKILL.md skillA

code-audit from arcasilesgroup/ai-engineering is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add arcasilesgroup/ai-engineering/code-audit@git:20260901.dca22e5

Pins git:20260901.dca22e5 in mdr.lock. Pin the fingerprint instead.

Review code for correctness bugs, concurrency and lifecycle errors, type-safety holes, error handling gaps, API-contract breaks, and maintainability problems, with every finding gated on a concrete failure scenario. Use when asked to review code, check a diff or branch for bugs, look for problems before committing or opening a PR, or assess code quality.

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

# Code audit

Find defects that will actually bite.

Read `.claude/review/CONVENTIONS.md` first — stack detection, scope, severity,
the false-positive gate, and the report format. The **installed-version rule** is
the single most important constraint here: verify against the installed source
before calling any framework or library API misuse. Most false positives in a
review like this come from reviewing the code as if it were an older version of
its framework.

Security is out of scope — that is `security-audit`. Accessibility is
`a11y-audit`, performance is `perf-audit`. Overlap is fine; do not go hunting
outside your lane.

## What to look for

Ordered by how often each actually causes damage. Read files fully — the bug is
usually in the interaction between two functions, not inside one.

**1. Correctness**
Logic that produces a wrong result: off-by-one and boundary conditions, inverted
or short-circuiting conditionals, null/nil/undefined reaching a dereference,
zero-values hitting a truthiness check that meant "absent" (`0`, `""`, empty
collection, `false`), index and slice assumptions, integer division and rounding,
…

How to install

The exact contents, by fingerprint
mdr add arcasilesgroup/ai-engineering/code-audit@sha256:5acb51038ba1ec9a

The line at the top of this page pins the label git:20260901.dca22e5, 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.
