* `response_webhook_secret` — secret used to sign webhook payloads
* `llm_provider` — LLM provider (`openai`, `anthropic`, `replicate`, `openclaw`)
* `llm_api_key` — API key for the configured LLM provider
* `ollama_endpoint` — endpoint URL for a self-hosted Ollama instance
* `ollama_model` — model name when using Ollama
* `openclaw_gateway` — OpenClaw gateway URL for native integration
* `openclaw_token` — OpenClaw gateway token (encrypted at rest)
* `openclaw_agent_id` — OpenClaw agent ID (defaults to `"main"`)
* `role` — the agent's role description
* `personality` — the agent's personality prompt
