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

Use the `nix-style` skill.
Audit ${ARGUMENTS:-the staged diff} for violations of the repository Nix style rules.

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
`path:line`: Finding title.
Summary: why the code breaks the rule
Fix: suggested fix
```

It is acceptable to report no findings when the reviewed Nix already follows the loaded rules.
