second-opinion skillA

second-opinion is agent-read markdown (skill) from photostructure/coding-skills: Get a second opinion on freshly written code from the *other* coding agent — Claude asks Codex, Codex asks Claude — then empirically vet every finding against ground truth before accepting or vetoing it. Use when requested or as part of an active review workflow after tests pass. Do not trigger merely because the user instructs you to commit, or for a delegated review or finding-validation pass..

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 photostructure/coding-skills/second-opinion@git:20260914.48b56a8
Exact content
mdr add photostructure/coding-skills/second-opinion@sha256:86857586b43b454b

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.
