verification-oracle skillA

verification-oracle is agent-read markdown (skill) from metraton/gaia: Use when re-running a task_gates entry (or a proposed contract verification block) whose verification_type is `command` or `code`, to deterministically re-execute the declared check and compare the actual result against the gate's expected value -- not for `semantic` or `self_review` gates, which need judgment rather than re-execution..

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 metraton/gaia/verification-oracle@git:20260722.268971e
Exact content
mdr add metraton/gaia/verification-oracle@sha256:ee6eaba613675576

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.
