Diagnose cc-thingz plugin installations with the bundled read-only doctor. Use for missing installed skills, helpers, or hook files, stale package versions, duplicate packages, or migration from old cc-thingz packages. NOT for broad agent configuration audits or config edits; use evolving-config.
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
# Installation Doctor Inspect installed resources without a repository checkout. The helper compares files against its bundled release catalog; it does not execute hooks or modify installations. ## Run 1. Locate `scripts/doctor.py` relative to this installed `SKILL.md`. 2. Use an existing Python 3.12+ interpreter with `-B`. If using uv, run `uv run --no-project python -B <skill-directory>/scripts/doctor.py --json`. uv may populate its own cache; use an existing interpreter directly when the entire invocation must be read-only. 3. Select roots for the requested runtime. Without root options the helper inspects the Codex cc-thingz marketplace cache and user flat skill directories. For Claude or a specific installation, pass `--plugin-root <directory>`. Repeat `--plugin-root` or `--skill-root` for multiple locations. Any explicit root option restricts inspection to supplied roots. 4. Optionally pass `--config-root <.codex-directory>` to check agent profile presence, or `--repo <cc-thingz-checkout>` for comparison with source manifests. 5. Summarize failed checks with paths, migration suggestions, and verification …

How to install
mdr add alexei-led/cc-thingz/installation-doctor@sha256:0af852dad8de5c05The line at the top of this page pins the label git:20260929.e2cd2eb, 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.
