improve-rust-tests

What problem does it solve?

Rust test suites often drift into unclear coverage, brittle assertions, and missing invariants, making regressions harder to detect and trust harder to build.

Core Features & Use Cases

• Wide, evidence-grounded test review: Evaluates placement, coverage shape, readability, and fit to Rust testing guidance rather than adding tests for their own sake.
• Candidate-first improvement planning: Surfaces substantial change options (files, problems, proposed changes, tooling, and verification) before editing.
• TDD-aligned execution and refactoring: Builds or refactors tests vertically for targeted behaviors, then cleans up redundant or misleading tests.

Quick Start

Use the improve-rust-tests skill to audit your Rust project’s existing unit/integration/doctest/property tests, propose a prioritized set of improvements, and implement the changes that best strengthen behavior coverage and invariants.
