test-discipline SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 4 indexed copies. Same content hash, so the same checks give both the same grade.
test-discipline from microsoft/waza is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Design assertions that prove the actual contract and fail on realistic regressions.
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
## Context Use this skill whenever a change affects an API, public interface, workflow contract, generated artifact, or user-observable behavior. A passing status-only test is not evidence that the intended artifact or contract is correct. ## Patterns - Update tests in the same change as an API, signature, export, or public-interface change. - Make assertions name and inspect the offending artifact, output, or configuration field—not just an exit code or broad success status. - Mutation-test critical gates by changing the real source or emitted artifact and proving the assertion turns red. - Exercise every caller path for a changed parser, normalizer, or helper; isolated unit coverage can miss the integration path that invokes it differently. - Reproduce working-tree-only failures locally when the contract depends on index, filesystem, line-ending, or generated-output state. - Keep expected inventory arrays synchronized with the files they enumerate. ## Examples A workflow-compilation test mutates the source workflow, compiles it, and inspects the emitted safe-output contract. A repair-script test constructs the actual index/blob/worktree state that …

How to install
mdr add microsoft/waza/test-discipline@sha256:d84983f8e88130a6The line at the top of this page pins the label git:20261016.42d1b9f, 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.
