@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 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:

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:

export OMO_CODEX_DISABLE_POSTHOG=1
# or globally for every OMO product:
export OMO_DISABLE_POSTHOG=1
