# Heimdall Rust Dependency Audit Use this skill for dependency, security, license, or unused-dependency audit work in Heimdall. ## Workflow 1. Run `cargo audit` if available; otherwise note the missing tool. 2. If `deny.toml` exists and `cargo deny` is available, run `cargo deny check`. 3. If `cargo machete` is available, run it to find declared but unused dependencies. 4. Summarize the actionable findings. ## Guardrails - This is report-first. - Do not create or edit `deny.toml` in this v1 workflow unless the user explicitly asks. - Do not auto-edit `Cargo.toml` or lockfiles as part of the audit pass. ## Output expectations - Report which tools were available and which commands were run. - Group findings into advisories, policy or license issues, and unused dependencies. - If a fix is obvious, suggest the concrete version bump or cleanup target.
