Guide maintainable tests as behavior documentation with isolated side effects, compatibility coverage, and reliable assertions. Use for tests, fixtures, mocks, regressions, reviews, and testability changes. Skip disposable work.
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
# maintainable-tests Write, edit, refactor, and review tests so a developer returning months later can understand the behavior, the edge cases, and the reason each important test exists. ## Passive Trigger Load this skill in the background whenever the task involves automated tests, examples used as tests, fixtures, mocks, stubs, fakes, test data builders, regression coverage, characterization tests, flaky tests, or production-code changes made to improve testability. Keep it lightweight for small edits: apply the core rules silently, then mention only the test-design decisions that affect the final implementation. ## Decision Tree Consult the relevant reference only when a non-obvious test-design decision needs more detail than these rules or local examples provide. A matching topic does not require a reference read. - Adding tests for new behavior: Name each test after the user-visible rule or domain invariant, then use concrete examples that teach the behavior. Consult `references/principles.md` or `references/naming-and-intent.md` if intent is unclear. - Fixing a bug or adding regression coverage: …

How to install
mdr add jpcaparas/skills/maintainable-tests@sha256:f1b220d8e7234c5bThe line at the top of this page pins the label v1.1.0, 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.
