rust-testing-quality SKILL.md skillA
rust-testing-quality from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/rust-testing-quality@git:20260927.43a351cPins git:20260927.43a351c in mdr.lock. Pin the fingerprint instead.

Use when writing, organizing, or running Rust tests — unit, integration, doc-tests, proptest, criterion benchmarks, or cargo-mutants. Not for CI pipeline wiring (rust-tooling-cicd).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> This skill covers organizing and running the full Rust test spectrum: unit tests in #[cfg(test)] modules, integration tests in tests/*.rs against the public API only, doc-tests compiled from /// examples, property-based testing with proptest (including committing proptest-regressions/), criterion benchmarks (harness = false), and mutation testing with cargo-mutants as a scheduled quality gate rather than a per-push check. It also covers the nextest doctest pitfall: `cargo nextest run` never runs doc-tests, so `cargo test --doc` must always be paired alongside it — a green nextest run alone is not full coverage. Out of scope: CI pipeline wiring and gate ordering belong to rust-tooling-cicd; non-Rust test suites are not covered. </objective> # Rust Testing & Quality ## Agent Workflow (MANDATORY) Before ANY test work, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Map existing `tests/`, `#[cfg(test)]`, `benches/` 2. **fuse-ai-pilot:research-expert** - Verify current nextest/proptest/criterion docs via Context7/Exa …

How to install
mdr add fusengine/agents/rust-testing-quality@sha256:dffee6b6adc4ddf3The line at the top of this page pins the label git:20260927.43a351c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
