Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.
/plugin marketplace add Yeachan-Heo/oh-my-claudecode/plugin install oh-my-claudecodeWrote this? Show the measurements

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.09405 |
| Opus 5 | $0.00009 | $0.04702 |
| Sonnet 5 | $0.00003 | $0.01881 |
| Haiku 4.5 | $0.00002 | $0.00941 |
Grade A, and why
configure-notifications scanned grade A with 1 finding 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 13d ago.
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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 1,215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Configure Notifications
Set up OMC notification integrations so you're alerted when sessions end, need input, or complete background tasks.
Routing
Detect which provider the user wants based on their request or argument:
- If the trigger or argument contains "telegram" → follow the Telegram section
- If the trigger or argument contains "discord" → follow the Discord section
- If the trigger or argument contains "slack" → follow the Slack section
- If no provider is specified, use AskUserQuestion:
Question: "Which notification service would you like to configure?"
Options:
- Telegram - Bot token + chat ID. Works on mobile and desktop.
- Discord - Webhook or bot token + channel ID.
- Slack - Incoming webhook URL.
Telegram Setup
Set up Telegram notifications so OMC can message you when sessions end, need input, or complete background tasks.
How This Skill Works
This is an interactive, natural-language configuration skill. Walk the user through setup by asking questions with AskUserQuestion. Write the result to ${CLAUDE_CONFIG_DIR:-~/.claude}/.omc-config.json.
Step 1: Detect Existing Configuration
CONFIG_FILE="${CLAUDE_CONFIG_DIR:-$HOME/.claude}/.omc-config.json"
if [ -f "$CONFIG_FILE" ]; then
HAS_TELEGRAM=$(jq -r '.notifications.telegram.enabled // false' "$CONFIG_FILE" 2>/dev/null)
CHAT_ID=$(jq -r '.notifications.telegram.chatId // empty' "$CONFIG_FILE" 2>/dev/null)
PARSE_MODE=$(jq -r '.notifications.telegram.parseMode // "Markdown"' "$CONFIG_FILE" 2>/dev/null)
if [ "$HAS_TELEGRAM" = "true" ]; then
echo "EXISTING_CONFIG=true"
echo "CHAT_ID=$CHAT_ID"
echo "PARSE_MODE=$PARSE_MODE"
else
echo "EXISTING_CONFIG=false"
fi
else
echo "NO_CONFIG_FILE"
fi
If existing config is found, show the user what's currently configured and ask if they want to update or reconfigure.
Step 2: Create a Telegram Bot
Guide the user through creating a bot if they don't have one:
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.

configure-notifications is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (39,107 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 9,405 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
oh-my-opencode-slim
Configure and improve oh-my-opencode-slim for the current user. Use when users want to tune agents, models, prompts, custom agents, skills, MCPs, presets, or plugin behavior. Also use when recurring workflow friction suggests a safe config or prompt improvement.
clonedeps
Clone important project dependency source code into an ignored local workspace so OpenCode can inspect library internals. Use when the user asks to clone dependencies, inspect dependency/source internals, understand SDK/framework behavior from source, debug library implementation details, or make core dependency repos…
codemap
Generate comprehensive hierarchical codemaps for UNFAMILIAR repositories. Expensive operation - only use when explicitly asked for codebase documentation or initial repository mapping.
deepwork
High-cost orchestrator workflow for large, high-risk, multi-phase coding efforts with meaningful dependencies and review gates. Do not activate for routine multi-file changes.
worktrees
Manage Git worktrees as OMO safe isolated coding lanes for complex, risky, or parallel work.
simplify
Simplifies code for clarity without changing behavior. Use for readability, maintainability, and complexity reduction after behavior is understood.
