tdd skillA

tdd is agent-read markdown (skill) from dayfinggg/openai-codex-agent-skills: Develop a feature or bug fix through a focused failing-test, minimal-implementation, and refactor loop. Use when the user requests TDD, asks for a regression test, or the bug has an obvious cheap local test target. Do not force TDD when the useful test path is unclear, expensive, or integration-heavy..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dayfinggg/openai-codex-agent-skills/tdd@git:20260905.b1dcd2a
Exact content
mdr add dayfinggg/openai-codex-agent-skills/tdd@sha256:749cc5824d0890e3

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
