validate-metadata skillA
validate-metadata is agent-read markdown (skill) from jmagly/aiwg: Validate AIWG extension definitions against the metadata schema and report errors with field names, line numbers, and remediation hints.
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
mdr add jmagly/aiwg/validate-metadata@git:20260513.5224108mdr add jmagly/aiwg/validate-metadata@sha256:2c9c5ceb0e8ab37cPin 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.
