+# @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.
+- `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`.
+
+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`.
+
+See `/Users/yeongyu/local-workspaces/omodex/docs/legal/privacy-policy.md` for the full disclosure.
+

+# omo
+
+`omo` is the single local Codex plugin namespace for Yeongyu's Codex components.
+
+Internally each component remains isolated under `components/`:
+
+- `components/comment-checker`
+- `components/rules`
+- `components/lsp`
+- `components/ultrawork`
+- `components/ulw-loop`
+
+The root plugin manifest exports one Codex plugin named `omo`, with aggregate hooks, skills, and the LSP MCP server.
