# mn:health — Vault Health Check & Analytics > **Invocation marker (both runtimes):** begin your reply with the exact line `🧠 mn:health (mnemo) → running` — the user-visible confirmation that this skill actually loaded. Emit it once per invocation, before any other output. ## Portable paths Resolve `<mnemo-root>` once to the absolute plugin root before reading bundled files or running bundled scripts. In Claude Code, use `${CLAUDE_PLUGIN_ROOT}`; in Codex, derive it from this loaded `SKILL.md` path (skill directory → `skills/` → plugin root). Replace `<mnemo-root>` with that quoted absolute path in every command — never execute the placeholder literally and never hunt versioned cache directories. When another mnemo skill must run, use the runtime-native path: Claude Code invokes `mn:<skill>` through its Skill tool; Codex reads `<mnemo-root>/skills/<skill>/SKILL.md` completely and follows it with the prepared input. For user-facing explicit syntax, render `/mn:<skill>` in Claude Code and `$mnemo:<skill>` in Codex. Run a comprehensive health check on the Obsidian vault: orphans, broken links, missing sections, stale notes, and growth statistics. ## Prerequisites & config Obsidian must be open; `obsidian` CLI on PATH. Config at `~/.mnemo/config.json` requires `vault`, `taxonomy`, `taxonomy_roles`, and `links_section` for new configs; the deterministic legacy Zettelkasten fallback remains supported. Validate the exact role contract in Step 4 before semantic labeling. Schem...
