rust-tdd SKILL.md skillA
rust-tdd from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lu1sdv/skillsmd/rust-tdd@git:20261011.8d24f4cPins git:20261011.8d24f4c in mdr.lock. Pin the fingerprint instead.

Use when implementing Rust features test-first, reproducing Rust bugs with regression tests, characterizing legacy Rust, or applying red-green-refactor with cargo test. Covers boundary and equivalence cases, proptest shrinking, mockall expectations, rstest fixtures, async/concurrent/CLI tests, and coverage interpretation. Not a substitute for system-wide test strategy or benchmarking.
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
# Rust TDD Drive a small behavior change with an observed failure, a complete working fix, and a behavior-preserving refactor. The compiler checks types and ownership; it does not establish business rules, deadlock freedom, or correct error handling. ## Quick Reference | Need | Action / reference | |---|---| | New feature | Acceptance example → one failing behavior → smallest complete implementation | | Reported bug | Add regression at the shared failing path; preserve the reported evidence | | Legacy change | Characterize behavior first; distinguish compatibility from approved bug fixes | | Boundary inventory, testability | [Workflows and testability](references/workflows-and-testability.md) | | Broad input space, shrinking | [Properties, doubles, and fixtures](references/properties-doubles-fixtures.md) | | External interaction | Real value/function first; stub/fake/mock only at an actual dependency boundary | | Async, concurrency, CLI, CI, coverage | [Scenarios and tooling](references/scenarios-and-tooling.md) | | Attribution and technical corrections | [Sources](references/sources.md) | ## Establish the contract before the first test …

How to install
mdr add lu1sdv/skillsmd/rust-tdd@sha256:4d37a78ec087c48cThe line at the top of this page pins the label git:20261011.8d24f4c, 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.
