[!NOTE] **[OmO] 60K Stars: the terrifying token burner has arrived in LazyCodex.**

Sisyphus Labs' OmO is the quality-obsessed agent harness whose public lore says it loved Anthropic models hard enough to get third-party clients blocked. Now that same OmO quality bar is available for Codex through LazyCodex.

If you wanted OmO but did not want the setup ceremony, start here:

npx lazycodex-ai install

Context: [OmO 60K Stars on X](https://x.com/justsisyphus/status/2060210365338939452?s=20)

🚀 Install

One line. No global install, no `npm i -g`. Always use `npx`:

npx lazycodex-ai install

This is shorthand for `npx --yes --package oh-my-openagent omo install --platform=codex`. For a fully autonomous, no-TUI setup:

npx lazycodex-ai install --no-tui --codex-autonomous

Install from the Codex marketplace (experimental)

The npx installer above stays the primary path. As an additive, experimental alternative you can install from inside Codex itself: type `/plugins`, open the **Add Marketplace** tab ("Add a marketplace from a Git repo or local root."), and enter `https://github.com/code-yeongyu/lazycodex`, then install `omo` from the `sisyphuslabs` marketplace. Or from the CLI:
