codex.ts

// Codex — driven through the official ACP bridge for the OpenAI Codex CLI
// (@agentclientprotocol/codex-acp, successor to @zed-industries/codex-acp).
// Suggested command: `npx -y @agentclientprotocol/codex-acp` (the `-y` keeps the
// first npx fetch non-interactive so one-click Connect can't hang on a prompt).
// The bridge auths via the user's ChatGPT login (codex CLI) or an OpenAI API
// key — which is why the key env vars are forwarded for this adapter only, and
// why `openAiApiKey` (from Omi's encrypted store) is injected as OPENAI_API_KEY.
