description: Review changes against repository style rules
argument-hint: "[target]"
---

Review target: `${ARGUMENTS:-the staged diff}`.
Audit the target for violations of the repository style rules.

Choose skills from the reviewed files:

- Use the `nix-style` skill for `*.nix` files.
- Use the `rust-style` skill for `*.rs` files.
- Use the `build-style` skill for `Cargo.toml` files.
- Use the `build-style` skill for Bazel `BUILD` files.

If the target includes multiple matching file types, use all matching skills.
If the target is a diff, choose skills from the changed files.
Do not use a style skill when no reviewed file matches it.

Report only actionable findings.
Order findings by severity.
Do not report preferences unless a loaded rule states them.

Use this format for each finding:

```text
`code-path:line`
> `smallest reviewed-code excerpt that shows the violation`

`skill::rule-file:line`: Finding title.
Summary: why the code breaks the rule
Fix: suggested fix
```

Keep the code excerpt to one to three lines when possible.
Use a longer excerpt only when the violation needs surrounding context.
Use `...` to omit unrelated lines from a multi-line excerpt.
Use a style-skill rule citation in the form `skill::rule-file:line`.
Make the fix direct.
Do not include alternatives when one fix best follows the cited rule.

It is acceptable to report no findings when the target follows the loaded rules.
