Generate unit tests for specified functions using Codex exec.
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
# Codex Test Gen Thin entry-point skill — routes to the parent skill for full workflow. ## Parent Skill This skill delegates to `test-review` for the underlying transport. As a thin entry point it dispatches nothing itself, so it holds no transport grant. The generation-specific prompt template is at `@skills/test-review/references/codex-prompt-test-gen.md`. See `@skills/test-review/SKILL.md` ## Variant This is the **Generation** variant — creates new unit tests for specified functions. ## Trigger - Keywords: generate tests, write tests, create tests, codex-test-gen ## When NOT to Use - Reviewing existing test coverage (use `/codex-test-review`) - Code review (use `/codex-review-fast`) - Writing integration/e2e tests (use `/post-dev-test`)

How to install
mdr add sd0xdev/sd0x-harness/codex-test-gen@sha256:18f0b2974a98f498The line at the top of this page pins the label git:20260905.e7ebc99, 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.
