diagnose skillA

diagnose is agent-read markdown (skill) from mycelium-hq/ai-brain-starter: Use when an AI Brain vault needs a health check or something feels off: Claude ignores CLAUDE.md, journal entries missing from /weekly, hooks not firing, something broke after a git pull, a friend''s install misbehaves, Obsidian crashes or pegs the CPU, a .claude/worktrees folder appeared, Granola/WhatsApp/Slack/Gmail notes stopped arriving, or Windows .ps1 scripts error. Also after major /setup-brain upgrades. Not for debugging code; audits the vault install only..

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 mycelium-hq/ai-brain-starter/diagnose@git:20260816.6ac8364
Exact content
mdr add mycelium-hq/ai-brain-starter/diagnose@sha256:e23752950a7ab03e

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.
