Use only when the user explicitly invokes obra test-driven-development for iron-law examples. Core TDD is docs/ai/skills/tdd/SKILL.md. Do not use this for docs-only, formatting-only, or generated-mirror changes.
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-Driven Development (TDD) <!-- CORE-OVERLAY-START --> ## This repository (Asymmetric-al/core) Core's authoritative TDD skill is `docs/ai/skills/tdd/SKILL.md`. This obra companion stays available for its iron-law examples, but Matt Pocock / Core TDD wins on repo workflow, seams, and skip rules. Keep Core's Base UI, `base-maia` style, Zinc tokens, and `docs/ai/rules/frontend.md` authoritative. Reconcile this overlay after upstream refreshes before running `bun run skills:sync`. ### Triggers - The user explicitly asks for the obra Superpowers TDD skill. - Ordinary Core implementation still uses `docs/ai/skills/tdd/SKILL.md` automatically. ### Workflow 1. Load `docs/ai/skills/tdd/SKILL.md` first. 2. Do not invent a failing test for documentation-only, formatting-only, exact generated-mirror, or provenance-only skill work. 3. Keep Vitest + Bun commands from Core's testing rulebook. 4. `base-maia` is unrelated to TDD; do not let this skill change UI ownership. ### Checklist - [ ] `docs/ai/skills/tdd/SKILL.md` remained the Core TDD owner. - [ ] Documentation/mirror/provenance work skipped a fake red test. <!-- CORE-OVERLAY-END --> ## Overview …

How to install
mdr add asymmetric-al/core/test-driven-development@sha256:cf687c807dee63c4The line at the top of this page pins the label git:20261022.752a38b, 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.
