omo for Claude Code

The lazy way to run omo inside Claude Code. A native Claude Code plugin marketplace by Sisyphus Labs.

What it is

omo for Claude Code brings the omo experience — rule injection, comment checking, LSP intelligence, ultrawork orchestration, durable ultragoal tracking, and start-work continuation — into Claude Code through Claude Code's native plugin system.

This repository is the distribution surface: a native Claude Code plugin marketplace. The marketplace is named sisyphuslabs and ships a single plugin named omo. The repository name (lazyclaudecode) is the install alias and the home of this marketplace — it is not the marketplace name.

The marketplace name is sisyphuslabs. The plugin name is omo. You install the plugin as omo@sisyphuslabs.

Everything is self-contained: hooks, skills, subagents, and the bundled MCP servers all resolve from ${CLAUDE_PLUGIN_ROOT}, so the plugin runs correctly straight from the Claude Code plugin cache.

Install

Native (recommended)

Add this marketplace, then install the omo plugin:

/plugin marketplace add code-yeongyu/lazyclaudecode
/plugin install omo@sisyphuslabs

Via the omo CLI

# Claude Code platform (cc is the short alias for claudecode):
bunx omo install --platform=cc

# or via the dedicated alias (same compiled CLI, defaults to Claude Code):
bunx lazyclaudecode install

The omo CLI shells out to claude plugin marketplace add code-yeongyu/lazyclaudecode and claude plugin install omo@sisyphuslabs. If claude is not on your PATH, it prints the two /plugin commands above so you can run them inside a Claude Code session.

Components

omo is one plugin namespace; each capability stays isolated internally as a component.

Component What it does
rules Injects AGENTS.md / CLAUDE.md / .omo/rules/** into context via SessionStart, UserPromptSubmit, PostToolUse, and PostCompact.
comment-checker Runs comment-checker after Write / Edit / MultiEdit tool use to keep comments honest.
lsp Exposes Language Server Protocol diagnostics, navigation, symbols, and rename through MCP plus post-edit hooks.
ultrawork Detects ultrawork / ulw in a prompt and injects the full ultrawork orchestration directive.
ultragoal Durable, repo-native multi-goal orchestration with embedded success criteria and an observable evidence audit under .omo/ultragoal/, scoped per Claude Code session.
start-work-continuation A Stop / SubagentStop continuation hook that resumes .omo/boulder.json start-work plans, keyed per Claude Code session.
telemetry Anonymous, opt-out daily-active signal emitted on the plugin SessionStart hook.

MCP servers

omo bundles two MCP servers, wired through ${CLAUDE_PLUGIN_ROOT} so they spawn cleanly from the plugin cache:

Server Purpose
ast_grep Structural code search and rewrite via ast-grep.
lsp Language Server Protocol tools: diagnostics, definitions, references, symbols, rename.

Skills & subagents

Installing omo registers a library of skills (init-deep, planning, refactor, remove-ai-slops, review-work, start-work, and more) and a set of subagents for orchestrated work:

Subagent Role Model
reviewer Reviews ultrawork output against the directive. opus
metis Strategic planning and decomposition. opus
planner Turns objectives into executable plans. opus
momus Adversarial critique of plans and changes. opus
explorer Fast, read-only codebase reconnaissance. haiku
librarian Fast, read-only documentation and reference lookup. haiku

Skills carry a Claude Code Harness Tool Compatibility section so they speak in Claude Code's native verbs (Edit, Write, MultiEdit, Task).

Telemetry

omo for Claude Code sends an anonymous, at-most-once-per-UTC-day "still alive" signal so the project can gauge real-world usage. It uses the same PostHog project as the wider omo family but emits the distinct event omo_claude_daily_active. The signal is keyed to a SHA256-hashed installation identifier, person profiles are suppressed, and the daily dedup state is stored locally.

Opt out

# Claude Code only:
export OMO_CLAUDE_DISABLE_POSTHOG=1
export OMO_CLAUDE_SEND_ANONYMOUS_TELEMETRY=0

# Globally (also silences the rest of the omo family):
export OMO_DISABLE_POSTHOG=1
export OMO_SEND_ANONYMOUS_TELEMETRY=0

Setting OMO_DISABLE_POSTHOG disables omo for Claude Code telemetry too — the global flag is inherited.

Relationship to the omo family

omo ships in editions tuned to each agent harness. They all share the same core ideas and the same sisyphuslabs identity.

Edition Harness Distribution
Ultimate OpenCode omo OpenCode plugin
Light (Codex) OpenAI Codex lazycodex
Light (Claude Code) Claude Code this repo — lazyclaudecode

All editions descend from oh-my-openagent (omo).
