Agent¶
An autonomous loop: input -> tool calls -> final answer.
The provider never sees tool-use APIs. The protocol renders tool
instructions into the system prompt and parses tool calls out of the
model's plain-text responses; results are fed back as observations until
the model emits a final_answer envelope.
from_state(state, provider, tools=(), **kwargs)
classmethod
¶
Build an agent that continues the conversation stored in state.
Provider, tools and hooks are code — pass them here, not in the state.
The next run() appends its input to the loaded conversation.
run(input, *, max_iterations=25, on_max=OnMax.RAISE, control=None, output_model=None)
async
¶
Run the loop until final_answer, max_iterations or a hook stops it.
If this agent was built with from_state (or has run before), the
new input continues the existing conversation instead of starting one.
to_state()
¶
Snapshot the current session (conversation + audit history).
