+Common non-interactive setups:
+
+| Provider | Example command | Required auth | Tips |
+| --- | --- | --- | --- |
+| Claude CLI | `claude -p` (reads prompt from stdin) | `ANTHROPIC_API_KEY` or `claude login` | Add `--model claude-3-5-sonnet-20241022` or `--agent my-cascading-agent` to target a specific model or saved agent persona. |
+| Codex / OpenAI | `codex-cli --stdin --model gpt-4.1-mini` | `OPENAI_API_KEY` (+ `OPENAI_ORG_ID` if needed) | The stock `openai` CLI works via `openai api chat.completions.create -m gpt-4o-mini --input -`; wrap it if you prefer shorter aliases. |
+| Gemini | `gemini-cli --model=gemini-1.5-pro --stdin` | `GOOGLE_API_KEY`/`GEMINI_API_KEY` with Generative Language API enabled | Some CLIs default to streaming mode—add `--no-stream` or similar so stdout is plain text. |
+
+Update `config/ai.yml` to match the actual binary names or wrapper scripts on your machine.
