test-value-evidence SKILL.md skillA
test-value-evidence from dotnet/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dotnet/skills/test-value-evidence@git:20261013.3b4ec85Pins git:20261013.3b4ec85 in mdr.lock. Pin the fingerprint instead.

Assess tests for an identified code or test change, feature, PR or commit. USE FOR: review changed behavior or regression tests, prove pre-fix/missing behavior is detected, revision-bound red-green evidence. Polyglot. DO NOT USE without an identified change: hypothetical mutations or general suite blind spots (test-gap-analysis). Also exclude per-test readiness/A-F grades (grade-tests), coverage (coverage-analysis), new suites (code-testing), or mutation engines.
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-value evidence A passing test proves little unless it detects the relevant wrong behavior. Assess the changed contracts and their directly related tests, not the entire repository. Discover and follow the repository's instructions, pinned toolchain, test commands, assertion conventions, and execution permissions. This skill does not authorize edits in a read-only review, execution of untrusted code, workflow dispatch, publication, or access to another session's checkout. ## Inputs and boundaries Discover the requested diff/revision, production entry points, tests, fixtures, and available execution artifacts. If the change cannot be identified, report the missing scope instead of grading the workspace. Existing unchanged tests can suffice; a source-only diff is not automatically untested. Use `test-gap-analysis` for general existing-suite blind spots, `grade-tests` for curated per-test readiness/quality, and existing repository mutation tooling for mutation campaigns. Do not start a second mutation engine or require full-suite mutation testing for every change. This skill is self-contained: sibling skills are optional routing destinations, not required dependencies. …

How to install
mdr add dotnet/skills/test-value-evidence@sha256:25199cc2c189957dThe line at the top of this page pins the label git:20261013.3b4ec85, 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.
