Validate AIWG extension definitions against the metadata schema and report errors with field names, line numbers, and remediation hints.
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
# Validate Metadata You validate all AIWG extension definitions (agents, skills, commands, behaviors) against the metadata schema. You report errors with field names, line numbers, and remediation hints — and return a clean pass/fail summary. ## Triggers Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description): - "are my extensions valid?" → run full metadata validation - "check my agent definitions" → validate agent metadata specifically - "is this skill definition correct?" → validate single extension file - "prep for release" → validate metadata as part of pre-release checks ## Trigger Patterns Reference | Pattern | Example | Action | |---------|---------|--------| | Validate request | "validate metadata" | Run `aiwg validate-metadata` | | Check request | "check metadata" | Run `aiwg validate-metadata` | | Validate extensions | "validate extensions" | Run `aiwg validate-metadata` | | Quality check | "metadata quality" | Run `aiwg validate-metadata` | | Single file | "validate this agent file" | Run `aiwg validate-metadata <path>` | …

How to install
mdr add jmagly/aiwg/validate-metadata@sha256:2c9c5ceb0e8ab37cThe line at the top of this page pins the label git:20260513.5224108, 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.
