Validate custom agent file format and structure. Use after creating or editing an agent, before committing agent changes, or when an agent fails to load.
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
# Agent File Validator
Validate agent files in `.claude/agents/` for correct format against the
official Claude Code spec (plus Director Mode conventions).

How to install
mdr add claude-world/director-mode-lite/agent-check@sha256:892c402d4c6111afThe line at the top of this page pins the label git:20261021.8facda8, 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.
