fix codex plugin disable env

 - **"no agents found on PATH"** — install one of: `claude`, `codex`, `gemini`, `opencode`, `cursor-agent`, `qwen`, `copilot`. Or switch to "Anthropic API · BYOK" in the top bar and paste a key in **Settings**.
 - **daemon 500 on /api/chat** — check the daemon terminal for the stderr tail; usually the CLI rejected its args. Different CLIs take different argv shapes; see `apps/daemon/src/agents.ts` `buildArgs` if you need to tweak.
+- **Codex loads too much plugin context** — start Open Design with `OD_CODEX_DISABLE_PLUGINS=1 pnpm tools-dev` to make daemon-spawned Codex processes run with `--disable plugins`.
 - **artifact never renders** — the model produced text without wrapping in `<artifact>`. Confirm the system prompt is going through (check daemon log) and consider switching to a more capable model or a stricter skill.
