--- description: Run one-shot environment diagnostics for Diagram Design readiness argument-hint: "[--strict] [--json]" allowed-tools: - Read - Bash - Glob --- Run environment diagnostics for Diagram Design by following [`skills/diagram-design/references/doctor.md`](../skills/diagram-design/references/doctor.md). Treat that reference as the source of truth and do not reimplement its logic here. Full argument string: `$ARGUMENTS` ## Required behavior 1. Locate and apply the exact checks and output contract from `references/doctor.md`. 2. Keep this command read-only: do not install dependencies, do not edit files, and do not run destructive git operations. 3. If a check command fails, capture stderr, mark the check `warn` or `fail` per the reference, and continue remaining checks. 4. Print the compact summary line plus per-check statuses, and include `Next actions` only when needed. 5. If `--json` is passed, append the structured JSON block defined by the reference. Report only verified results from this run.
