Think & Act AI Agent Framework — Dual-Stage Reasoning Pipeline

Most AI automations react. This one thinks first, then acts.

Built an n8n workflow using a two-stage AI agent architecture a "Think" agent and an "Act" agent running in sequence, each powered by OpenRouter with structured output parsers enforcing clean JSON at every step. A configuration node sets the full context upfront, the Think agent reasons through the task using memory and tool access, its output gets parsed and passed to the Act agent which executes based on that reasoning, and the final structured result is returned ready for the next step in any connected workflow.

The result is a reusable, modular AI reasoning layer that can be dropped into any automation stack where decisions need to be made intelligently before actions are taken.
