Its executable nodes use `chainLlm`, `chatTrigger`, `lmChatOllama`, `noOp`, `outputParserAutofixing`, `outputParserStructured`, `set`. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.\n\n## Setup\nImport inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.\n\n## Entry points\nWhen chat message received\n\n## Verification\nSanitized source candidate; not runtime-tested. This overview is generated from node metadata.
