Vigilante Rust Issue Implementation

Focus

• Read the prompt for detected tech stacks, process hints, and Rust security guidance before changing code.
• Follow idiomatic Rust conventions and keep changes scoped to the issue rather than broad cleanup.
• Preserve repository-specific toolchain, workspace, lint, and MSRV constraints when they are defined.

Rust Tooling Workflow

• Formatting: run cargo fmt on touched Rust code before committing. Respect rustfmt.toml when present and do not hand-format Rust code.
• Testing: run targeted cargo test commands for the affected crate, package, or workspace member first, then broaden scope only when changes cross crate boundaries or the correct target is unclear. Respect repository feature flags and default workspace behavior.
• Linting: run cargo clippy when it is available and relevant to the changed Rust code. Prefer the repository's existing Clippy configuration and fix meaningful warnings instead of suppressing them broadly.
• Security and supply-chain checks: run cargo-audit or cargo deny when those tools are already installed or configured and the change touches dependencies or security-sensitive code. If they are unavailable, note that and continue with the repository's existing validation rather than fabricating output.
• Dependencies: keep dependency additions minimal, review default features carefully, and prefer the Rust standard library when it covers the need. Respect Cargo.lock, workspace dependency policy, and any MSRV or toolchain pinning before introducing new crates or language features.

Rust Safety and Code Quality

• Keep unsafe code minimal, justified, and tightly scoped. Do not introduce unsafe when a safe standard approach is available.
• Prefer returning Result and propagating errors cleanly over panicking in normal control flow.
• Use feature flags deliberately. Avoid enabling broad optional features unless the issue requires them.
• Respect existing lint levels and crate-level policies such as #![forbid(unsafe_code)], #![deny(warnings)], or repository-specific Clippy settings.
