Add focused deterministic tests, fixtures, or smoke checks.
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
# Test Mini ## Purpose Protect against wrong behavior without heavy tests. ## When to use Use for ML model workflows, agents, dashboards, data transformations, metric calculations, scheduled jobs, and any behavior that can appear to run while being wrong. ## Inputs - Implemented slice - Expected behavior - Available fixtures or examples - Build/test/run commands - Optional SPEC test-sensitivity contract ## Workflow 1. Add one deterministic behavior test when possible. 2. Add one fixture or golden example when useful. 3. Add one smoke test or manual verification path. 4. Run exact commands. 5. If SPEC marks `Test sensitivity requirement: REQUIRED`, run the targeted fault-injection pass described below. 6. Record command output and result. 7. Keep tests focused on the changed behavior. ## Test sensitivity pass Use this only when SPEC explicitly requires it. The point is to prove a targeted test is sensitive to the behavior it claims to protect, not to maximize mutation coverage. For each declared Sensitivity ID: 1. Start from the declared `Test command` and `Fault model`. 2. Inject one narrow fault that should violate the protected behavior. …

How to install
mdr add tmusser/ai-engineering-skills/test-mini@sha256:1dc0aa1f43843d52The line at the top of this page pins the label git:20261030.9f1d6eb, 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.
