+# @oh-my-opencode/omo-codex
+
+Codex harness adapter for **oh-my-openagent**. Brings the OMO experience (rules injection, comment checker, LSP MCP, ultrawork, ultragoal) 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 5 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 (port of the original `codex-plugins/scripts/install-local.mjs`). |
+| `src/` | TypeScript runtime: installer + telemetry consumed by the omodex CLI. |
+| `MARKETPLACE.md` | Vendored upstream marketplace README. |
+
+## 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` (Python) - keyword detector (`ulw` / `ultrawork`) that injects the full ultrawork directive, plus a `SessionStart` hook that syncs bundled agent TOML files into `CODEX_HOME/agents`.
+- `ultragoal` (TypeScript) - durable multi-goal orchestration backed by `.omo/ultragoal/` evidence audit.
+
+## Install
+
+End users invoke through the omodex CLI:
+
+```bash
+bunx omo install --codex=yes
+# or, equivalently:
+bunx oh-my-opencode install --codex=yes
+bunx oh-my-openagent install --codex=yes
+```
+
+The installer copies the built plugin into `~/.codex/plugins/cache/code-yeongyu-codex-plugins/omo/<version>/`, enables it in `~/.codex/config.toml`, and links the per-component binaries into `~/.local/bin/` (or `CODEX_LOCAL_BIN_DIR`).
+
+## Telemetry
+
+Anonymous telemetry uses the same PostHog project as oh-my-openagent but emits the distinct event `omo_codex_daily_active`. Opt out with:
+
+```bash
+export OMO_CODEX_DISABLE_POSTHOG=1
+# or globally for every OMO product:
+export OMO_DISABLE_POSTHOG=1
+```
+
+See `/Users/yeongyu/local-workspaces/omodex/docs/legal/privacy-policy.md` for the full disclosure.
+
+## Provenance
+
+Vendored from [`code-yeongyu/codex-plugins`](https://github.com/code-yeongyu/codex-plugins) at the snapshot present in `/Users/yeongyu/local-workspaces/codex-plugins/` on 2026-05-25. Per-component upstream:
+
+- [code-yeongyu/codex-rules](https://github.com/code-yeongyu/codex-rules)
+- [code-yeongyu/codex-comment-checker](https://github.com/code-yeongyu/codex-comment-checker)
+- [code-yeongyu/codex-lsp](https://github.com/code-yeongyu/codex-lsp)
+- [code-yeongyu/codex-ultrawork](https://github.com/code-yeongyu/codex-ultrawork)
+- [code-yeongyu/codex-ultragoal](https://github.com/code-yeongyu/codex-ultragoal)
