Install or refresh oh-my-claudecode for plugin, npm, and local-dev setups from the canonical setup flow.
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
# OMC Setup This is the **only command you need to learn**. After running this, everything else is automatic. **When this skill is invoked, immediately execute the workflow below. Do not only restate or summarize these instructions back to the user.** Note: All `~/.claude/...` paths in this guide respect `CLAUDE_CONFIG_DIR` when that environment variable is set. ## Best-Fit Use Choose this setup flow when the user wants to **install, refresh, or repair OMC itself**. - Marketplace/plugin install users should land here after `/plugin install oh-my-claudecode` - npm users should land here after `npm i -g oh-my-claude-sisyphus@latest` - local-dev and worktree users should land here after updating the checked-out repo and rerunning setup ## Flag Parsing Check for flags in the user's invocation: - `--help` → Show Help Text (below) and stop - `--local` → Phase 1 only (target=local), then stop - `--global` → Phase 1 only (target=global), then stop - `--force` → Skip Pre-Setup Check, run full setup (Phase 1 → 2 → 3 → 4) - No flags → Run Pre-Setup Check, then full setup if needed ## Help Text When user runs with `--help`, display this and stop: ``` …

How to install
mdr add yeachan-heo/oh-my-claudecode/omc-setup@sha256:5651e1bb2093e1f1The line at the top of this page pins the label git:20260827.e8b64b5, 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.
