-Apply that template with these values:
+Use the `nix-style` skill.
+Audit ${ARGUMENTS:-the staged diff} for violations of the repository Nix style rules.
 
-- skill: `nix-style`
-- target: `${ARGUMENTS:-the staged diff}`
+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`
+
+`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 skill-relative rule citation, such as `let.md:7`.
+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 reviewed Nix already follows the loaded 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 `rust-style` skill for `Cargo.toml` files.
+- Use the `rust-style` skill for Bazel files that define Rust targets.

+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.
