## Description

Install or refresh oh-my-claudecode for plugin, npm, and local-dev setups from the canonical setup flow

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# 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:

```
