# @oh-my-opencode/omo-codex

Codex harness adapter for **oh-my-openagent**. Brings the OMO experience (rules injection, comment checker, LSP MCP, ultrawork, ulw-loop, start-work continuation, telemetry) into [OpenAI Codex CLI](https://github.com/openai/codex) through Codex's native plugin system.

## Layout

| Path | Purpose |
|------|---------|
| `plugin/` | Vendored Codex plugin namespace `omo` with isolated components. Shipped to the user via `~/.codex/plugins/cache/`. |
| `marketplace.json` | Codex marketplace manifest. Identifies `omo` as the single installable plugin. |
| `scripts/` | Node ESM build scripts for Codex cache installation and marketplace config updates. |
| `src/` | TypeScript runtime: installer + telemetry consumed by the omodex CLI. |
| `MARKETPLACE.md` | Native Codex marketplace notes for `sisyphuslabs` / `omo`. |

## Components Vendored

- `rules` (TypeScript) - injects `AGENTS.md` / `CLAUDE.md` / `.omo/rules/**` into context via `SessionStart`, `UserPromptSubmit`, `PostToolUse`, `PostCompact`.
- `comment-checker` (TypeScript) - runs `@code-yeongyu/comment-checker` after `apply_patch` / `edit` / `write` tool use.
- `lsp` (TypeScript + LSP MCP) - exposes LSP diagnostics, navigation, symbols, rename via MCP + post-edit hooks.
- `git-bash` (TypeScript + Git Bash MCP) - exposes the Windows-only `git_bash` MCP and reminds Codex on the first shell-like call, including the first one after compaction.
- `ultrawork` (TypeScript) - keyword detector (`ulw` / `ultrawork`) that injects the full ultrawork directive; bundled agent TOML files are installed into `CODEX_HOME/agents`.
- `ulw-loop` (TypeScript) - durable multi-goal orchestration backed by `.omo/ulw-loop/` evidence audit.
- `start-work-continuation` (TypeScript) - `Stop` / `SubagentStop` continuation hook for `.omo/boulder.json` start-work plans.
- `telemetry` (TypeScript) - anonymous daily active telemetry hook.

## Install

End users invoke through the omodex CLI. This package is the **Light edition** of omo — install it directly with:

```bash
bunx omo install --platform=codex
# or via the shortcut alias (same compiled CLI, defaults --platform=codex):
bunx lazycodex install
# or the longer package names:
bunx oh-my-opencode install --platform=codex
bunx oh-my-openagent install --platform=codex
```

To install **both** the Ultimate edition (OpenCode plugin) and the Light edition (this package) at once, use `--platform=both`.

The installer copies the built plugin into `~/.codex/plugins/cache/sisyphuslabs/omo/<version>/`, writes stable agent TOML links through `~/.codex/.tmp/marketplaces/sisyphuslabs/plugins/omo/`, enables `omo@sisyphuslabs` in `~/.codex/config.toml`, and registers the `sisyphuslabs` marketplace from the local built cache. `lazycodex` is the repo/npm/bin alias; the marketplace identity remains `sisyphuslabs`.

Native Windows installs prepare Git Bash before the installer mutates `~/.codex/`. If `bash.exe` is not already discoverable, the installer first tries the same best-effort install command shown here, then resolves Git Bash again:

```powershell
winget install --id Git.Git -e --source winget
where bash
```

For a custom Git Bash location:

```cmd
setx OMO_CODEX_GIT_BASH_PATH "C:\Program Files\Git\bin\bash.exe"
```

```powershell
$env:OMO_CODEX_GIT_BASH_PATH = "C:\Program Files\Git\bin\bash.exe"
```

Set `OMO_CODEX_SKIP_GIT_BASH_AUTO_INSTALL=1` to skip the best-effort `winget install --id Git.Git -e --source winget` attempt and keep the explicit install guidance path.

The installer does not write a global Codex shell config. On Windows it enables the plugin MCP policy for `git_bash`; on non-Windows it keeps the manifest bundled but writes `enabled = false` for that MCP server. The Git Bash hook injects fixed guidance before the first Codex shell-like `Bash` hook call in a session, and again before the first shell-like call after `PostCompact`, recommending `git_bash` before built-in `exec_command`.

To install both editions in one command, use `--platform=both`.

## Telemetry

Anonymous telemetry uses the same PostHog project as oh-my-openagent but emits the distinct event `omo_codex_daily_active`. The event is sent at most once per UTC day per machine from two sources:

| Source | Reason | Trigger |
|--------|--------|---------|
| `install` | `install_completed` | `bunx omo install --platform=codex` or `--platform=both` finishes (handled by `src/cli/install-codex/install-codex.ts`) |
| `plugin` | `session_start` | Codex plugin `SessionStart` hook fires (handled by `plugin/components/telemetry/`) |

Both sources share the same SHA256-hashed installation identifier (`sha256("omo-codex:" + hostname)`), suppress PostHog person profiles, and write the daily dedup state to `~/.local/share/omo-codex/posthog-activity.json`.

Opt out with:

```bash
# Codex-only
export OMO_CODEX_DISABLE_POSTHOG=1
export OMO_CODEX_SEND_ANONYMOUS_TELEMETRY=0

# Globally (also disables oh-my-openagent telemetry)
export OMO_DISABLE_POSTHOG=1
export OMO_SEND_ANONYMOUS_TELEMETRY=0
```

The identity constants and opt-out behavior are pinned across both sources by `src/telemetry/cross-package-equivalence.test.ts`.
