Use an agent to write tests that check behaviour rather than restate the implementation, and verify they can actually fail. Use when adding coverage to existing code.
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
# Agent test generation Agents produce tests quickly and default to tests that mirror the implementation, which pass regardless of whether the code is correct. The work is directing them toward behaviour and verifying the tests are capable of failing. ## Method 1. **Ask for behaviour tests, not coverage.** Given this input, expect this output, rather than exercising every branch for its own sake (see unit-test-design). 2. **Specify the cases you care about.** Edge cases, boundaries, and error paths, since agents over-produce happy-path tests. 3. **Verify each test can fail.** Break the implementation deliberately and confirm the test catches it, which is the only proof it tests anything (see mutation-testing). 4. **Reject tests that assert the implementation.** Tests reproducing internal calls break on every refactor and prove nothing (see test-doubles). 5. **Keep tests readable.** Clear names and obvious arrangement, because a generated test nobody understands is deleted at the first failure. 6. **Do not let it change code to make tests pass.** That inverts the relationship, and any implementation change must be a deliberate separate decision. …

How to install
mdr add amey-thakur/ai-skills/agent-test-generation@sha256:4e697e232db0d1dbThe line at the top of this page pins the label git:20260728.fac4544, 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.
