An installation and refresh workflow for oh-my-claudecode, a Claude Code plugin. It supports plugin, npm, and local development installations.

In plain words

Use it to perform a normal setup, force a full setup, or run only the local or global setup phase.
Why use it?
It provides one setup path for installing, updating, repairing, or checking the plugin instead of repeating separate setup steps.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

omc-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 189 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

OMC Setup - Configure oh-my-claudecode

USAGE:
  /oh-my-claudecode:omc-setup           Run initial setup wizard (or update if already configured)
  /oh-my-claudecode:omc-setup --local   Configure local project (.claude/CLAUDE.md)
  /oh-my-claudecode:omc-setup --global  Configure global settings (~/.claude/CLAUDE.md)
  /oh-my-claudecode:omc-setup --force   Force full setup wizard even if already configured
  /oh-my-claudecode:omc-setup --help    Show this help

MODES:
  Initial Setup (no flags)
    - Interactive wizard for first-time setup
    - Configures CLAUDE.md (local or global)
    - Sets up HUD statusline
    - Checks for updates
    - Offers MCP server configuration
    - Configures team mode defaults (agent count, type, model)
    - If already configured, offers quick update option

  Local Configuration (--local)
    - Downloads fresh CLAUDE.md to ./.claude/
    - Backs up existing CLAUDE.md to .claude/CLAUDE.md.backup.YYYY-MM-DD
    - Project-specific settings
    - Use this to update project config after OMC upgrades

  Global Configuration (--global)
    - Downloads fresh CLAUDE.md to ~/.claude/
    - Backs up existing CLAUDE.md to ~/.claude/CLAUDE.md.backup.YYYY-MM-DD
    - Default: explicitly overwrites ~/.claude/CLAUDE.md so plain `claude` also uses OMC
    - Optional preserve mode keeps the user's base `CLAUDE.md` and installs OMC into `CLAUDE-omc.md` for `omc` launches
    - Applies to all Claude Code sessions
    - Cleans up legacy hooks
    - Use this to update global config after OMC upgrades

  Force Full Setup (--force)
    - Bypasses the "already configured" check
    - Runs the complete setup wizard from scratch
    - Use when you want to reconfigure preferences

EXAMPLES:
  /oh-my-claudecode:omc-setup           # First time setup (or update CLAUDE.md if configured)
  /oh-my-claudecode:omc-setup --local   # Update this project
  /oh-my-claudecode:omc-setup --global  # Update all projects
  /oh-my-claudecode:omc-setup --force   # Re-run full setup wizard

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
