The platform executes action agents through a defined runtime sequence in which a Temporal workflow invokes the execute_action_agent activity, PyranaHarness runs the agent, the LLM creates an initial plan on turn 0, native tool-calling iterates until completion, and the system finalizes by building and persisting an AgentOutputEnvelope.

Execution Flow:

— PYRANA_PLATFORM_ARCHITECTURE_REFERENCE.md

1. Temporal Workflow (entry point) → `execute_action_agent` activity

— PYRANA_PLATFORM_ARCHITECTURE_REFERENCE.md

2. PyranaHarness.execute(config, workflow_input)

— PYRANA_PLATFORM_ARCHITECTURE_REFERENCE.md

3. Turn 0: create initial plan via LLM

— PYRANA_PLATFORM_ARCHITECTURE_REFERENCE.md

4. Native tool calling loop: LLM emits tool_calls → execute tools → observe → repeat

— PYRANA_PLATFORM_ARCHITECTURE_REFERENCE.md

5. Finalize: build and persist AgentOutputEnvelope
