The PYRANA_PLATFORM example defines a platform specification in which PyranaHarness uses LiteLLM for native tool calling, starts with a Turn 0 plan, iterates through tool-calling loops, and ends by finalizing an AgentOutputEnvelope.

"The PyranaHarness implements native LLM tool calling via LiteLLM, executing a Turn 0 plan followed by iterative tool calling loops until the agent finalizes an AgentOutputEnvelope"
