Skill validation framework PLUS daily test-suite health and regression intelligence. Validates skill conformance (frontmatter, manifest coverage, resolver coverage). Runs the project test suite in tiered phases (unit / evals / integration / system health), classifies failures, and produces a regression-aware report.
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
# Testing Skill — Validation + Daily Health & Regression Intelligence > **Convention:** see [conventions/quality.md](../conventions/quality.md) for > the test-before-bulk pattern; this skill enforces it across the project's > own test suite. ## Two modes This skill has two related but distinct modes: 1. **Skill conformance validation** — gbrain's own conformance bar (the original 1.0 scope). Validates every skill has SKILL.md with frontmatter, every reference exists, manifest + resolver coverage round-trips. 2. **Project test-suite health (v0.25.1 extension)** — runs the project's tiered test suite and produces a regression-classified report. Used by daily cron, container-restart bootstrap, and "how are the tests" prompts. Pick the mode by trigger. ## Mode 1: Skill conformance validation ### Contract This mode guarantees: - Every skill directory has a `SKILL.md` file - Every `SKILL.md` has valid YAML frontmatter (`name`, `description`) - Every `SKILL.md` has required sections per `test/skills-conformance.test.ts` - `skills/manifest.json` lists every skill directory - `skills/RESOLVER.md` references every skill in the manifest …

How to install
mdr add garrytan/gbrain/testing@sha256:c69fe3456aa981bbThe 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.
