  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Yeachan-Heo on GitHub. Read the source before you install it.

Installation

Install the Omc Setup AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Yeachan-Heo/oh-my-claudecode.git /tmp/oh-my-claudecode
mkdir -p .claude/skills
cp -r /tmp/oh-my-claudecode/skills/omc-setup .claude/skills/omc-setup
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Omc Setup in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Omc Setup on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Omc Setup is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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
    - Clears retired setup values (5.0.0 removed defaultExecutionMode) and points MCP registration at Claude Code's native config
    - Configures team mode defaults (agent count, type, model)
    - If already configured, offers quick update option

  Local Configuration (--local)
    - Invokes the plugin-local coordinator through `scripts/setup-claude-md.sh`; the shell validates the coordinator response and its exit status before any post-install work
    - Reports coordinator-created byte-identical backups only for files that required mutation
    - Project-specific settings
    - Use this to update project config after OMC upgrades

  Global Configuration (--global)
    - Invokes the plugin-local coordinator through `scripts/setup-claude-md.sh`; the shell validates the coordinator response and its exit status before any post-install work
    - Reports coordinator-created byte-identical backups only for changed global files
    - 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
    - Preserves same-named legacy hook files unless their exact historical contents are independently verified
    - 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

Setup Invocation

Do not independently scan plugin cache directories or select a plugin root in this skill. Invoke the setup script from the plugin root supplied by the running plugin environment:

bash
bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-claude-md.sh" <local|global> [overwrite|preserve]

The script is the sole cache resolver. It accepts only complete plugin roots (canonical docs/CLAUDE.md, coordinator artifact, and wiki skill), chooses a strict full-SemVer cache version, verifies the compiled-source handshake, and fails closed on coordinator protocol or status disagreement. Do not download configuration or mutate CLAUDE.md outside that coordinator.

Pre-Setup Check: Already Configured?

CRITICAL: Before doing anything else, check if setup has already been completed. This prevents users from having to re-run the full setup wizard after every update.

bash
# Check if setup was already completed
CONFIG_DIR="${CLAUDE_CONFIG_DIR:-$HOME/.claude}"
case "$CONFIG_DIR" in
  "~") CONFIG_DIR="$HOME" ;;
  "~/"*) CONFIG_DIR="$HOME/${CONFIG_DIR#\~/}" ;;
  "~\\"*) CONFIG_DIR="$HOME/${CONFIG_DIR#\~\\}" ;;
esac
CONFIG_FILE="$CONFIG_DIR/.omc-config.json"

if [ -f "$CONFIG_FILE" ]; then
  if ! command -v jq >/dev/null 2>&1; then
    echo "ERROR: jq is required to inspect existing OMC setup state. Existing config was not modified."
    exit 1
  fi
  if ! SETUP_COMPLETED=$(jq -r '.setupCompleted // empty' "$CONFIG_FILE" 2>/dev/null) \
    || ! SETUP_VERSION=$(jq -r '.setupVersion // empty' "$CONFIG_FILE" 2>/dev/null); then
    echo "ERROR: Existing OMC config is invalid JSON. Existing config was not modified."
    exit 1
  fi

  if [ -n "$SETUP_COMPLETED" ] && [ "$SETUP_COMPLETED" != "null" ]; then
    echo "OMC setup was already completed on: $SETUP_COMPLETED"
    [ -n "$SETUP_VERSION" ] && echo "Setup version: $SETUP_VERSION"
    ALREADY_CONFIGURED="true"
  fi
fi

If Already Configured (and no --force flag)

If ALREADY_CONFIGURED is true AND the user did NOT pass --force, --local, or --global flags:

Use AskUserQuestion to prompt:

Question: "OMC is already configured. What would you like to do?"

Options:

  1. Update CLAUDE.md and clear retired setup values - Install the active plugin's canonical CLAUDE.md and run Phase 2 Step 2.4 without re-running the full setup
  2. Run full setup again - Go through the complete setup wizard
  3. Cancel - Exit without changes

If user chooses "Update CLAUDE.md and clear retired setup values":

  • Detect if local (.claude/CLAUDE.md) or global (~/.claude/CLAUDE.md) config exists
  • If local exists, run: bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-claude-md.sh" local
  • If only global exists, run: bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-claude-md.sh" global
  • Run Phase 2 Step 2.4 to clear the retired defaultExecutionMode key
  • Skip all other steps after the cleanup
  • Report success and exit

If user chooses "Run full setup again":

  • Continue with Resume Detection below

If user chooses "Cancel":

  • Exit without any changes

Force Flag Override

If user passes --force flag, skip this check and proceed directly to setup.

Resume Detection

Before starting any phase, check for existing state:

bash
bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-progress.sh" resume

If state exists (output is not "fresh"), use AskUserQuestion to prompt:

Question: "Found a previous setup session. Would you like to resume or start fresh?"

Options:

  1. Resume from step $LAST_STEP - Continue where you left off
  2. Start fresh - Begin from the beginning (clears saved state)

If user chooses "Start fresh":

bash
bash "${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-progress.sh" clear

Phase Execution

For --local or --global flags:

Read the file at ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/omc-setup/phases/01-install-claude-md.md and follow its instructions. (The phase file handles early exit for flag mode.)

For full setup (default or --force):

Execute phases sequentially. For each phase, read the corresponding file and follow its instructions:

  1. Phase 1 - Install CLAUDE.md: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/omc-setup/phases/01-install-claude-md.md and follow its instructions.

  2. Phase 2 - Environment Configuration: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/omc-setup/phases/02-configure.md and follow its instructions. Phase 2 must delegate HUD/statusLine setup to the hud skill; do not generate or patch statusLine paths inline here.

  3. Phase 3 - Integration Setup: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/omc-setup/phases/03-integrations.md and follow its instructions.

  4. Phase 4 - Completion: Read ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/skills/omc-setup/phases/04-welcome.md and follow its instructions.

Graceful Interrupt Handling

IMPORTANT: This setup process saves progress after each phase via ${OMC_SETUP_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/setup-progress.sh. If interrupted (Ctrl+C or connection loss), the setup can resume from where it left off.

Keeping Up to Date

After installing oh-my-claudecode updates (via npm or plugin update):

Automatic: Just run /oh-my-claudecode:omc-setup - it will detect you've already configured and offer a quick "Update CLAUDE.md and clear retired setup values" option that skips the rest of the wizard.

The quick update path must still perform Phase 2 Step 2.4 so upgrades remove the retired defaultExecutionMode value; it must not write any replacement execution-mode setting.

Manual options:

  • /oh-my-claudecode:omc-setup --local to update project config only
  • /oh-my-claudecode:omc-setup --global to update global config only
  • /oh-my-claudecode:omc-setup --force to re-run the full wizard (reconfigure preferences)

This ensures you have the newest features and agent configurations without the token cost of repeating the full setup.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Omc Setup AI skill do?

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

Why use Omc Setup on TypingMind?

Because you install it once and use it with any model. Omc Setup is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Omc Setup in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Yeachan-Heo/oh-my-claudecode/tree/main/skills/omc-setup. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Omc Setup?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Omc Setup?

As many as you like. As long as a model supports skills, you can use Omc Setup with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Omc Setup AI skill free?

Yes. It is published on GitHub by Yeachan-Heo under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
