rust-debugger
Debug a Rust program or failing test with rdbg — set breakpoints (line, function, conditional, hit-count, panic, or watchpoint), run and step, read locals as real Rust values, change a variable mid-run, and jump to definition/hover/references via rust-analyzer. In tsz, reach for it on a runtime question reading hasn't localized — above all a wrong or extra (false-positive) diagnostic, where you break the diagnostic sinks and backtrace to the deciding frame instead of grepping emit sites. Skip it for missing-diagnostic bugs (nothing fires to break on) and small localized bugs a quick read already pins down.

rust-hygiene-audit
Run a deep DRY + code-hygiene audit of the Rust workspace and turn the findings into verified, deduplicated, hierarchical GitHub tech-debt issues. Use this whenever the user asks to find duplication, code smells, derive/boilerplate bloat, oversized files, or "tech debt"; to tighten the Clippy/lint posture; to mass-file or triage hygiene issues; or to assign Priority/Effort issue Fields across the backlog. Reach for it even when the user only says "clean up the codebase", "find DRY violations", "what should we refactor", or "make issues for the cruft" — it is the right tool for evidence-backed, non-spammy hygiene issue creation.
