Diagnose Open Claude Code installation, provider authentication, skill discovery, and CLI failures. Use when OCC fails to start, returns errors, or cannot find an installed skill.
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
# Diagnose Open Claude Code 1. Capture the failing command, exit status, Node version, and OCC version. Redact credentials and sensitive provider response bodies. 2. Require Node 20 or newer. Verify `npx --yes @ruvnet/open-claude-code@2.1.3 --version` and `--help` before a provider call. 3. For authentication failures, check only whether the required environment variable is present. Never print its value. Match ANTHROPIC_API_KEY to Anthropic or OPENAI_API_KEY to an OpenAI compatible endpoint. Routing depends on the model name: use `--model gpt-4.1-mini` for an OpenAI compatible route. Check base URL and model selection without exposing credentials. 4. For a newly published npm version returning ETARGET or E404, retry metadata/install with a fresh cache and prefer-online for at most five minutes. Do not treat authentication, integrity, or behavioral failures as propagation delays. 5. For missing skills, inspect project `.claude/skills/<name>/SKILL.md` and user `~/.claude/skills/<name>/SKILL.md`. OCC 2.1.2 follows directory symlinks; project skills override user skills. A broken symlink is ignored. …

How to install
mdr add ruvnet/open-claude-code/occ-diagnose@sha256:2ade3b84d1f91cb3The line at the top of this page pins the label git:20261011.cca6282, 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.
