🛠️ Improvements

Section titled “🛠️ Improvements”
  • agents: add reason to a rule when using requirements
  • backend: auto fix malformed tool calls (preventing ChatModelError)
  • backend: handle double-escaped tool calls
  • middlewares: propagate updates from StreamToolCallMiddleware without streaming enabled
  • adapters: add nested trajectory support for AgentStack when using serve module
  • backend: handle incomplete Unicode chunks while streaming
  • middlewares: GlobalTrajectoryMiddleware now emits events

GlobalTrajectoryMiddleware

Section titled “GlobalTrajectoryMiddleware”
agent = RequirementAgent(
    llm="ollama:granite4:micro",
    tools=[ThinkTool(), OpenMeteoTool()],
)


tool_call_logger = GlobalTrajectoryMiddleware(included=[Tool], target=False)


@tool_call_logger.emitter.on("start")
async def on_tool_start(data: GlobalTrajectoryMiddlewareStartEvent, _: EventMeta) -> None:
    run_data, run_meta = data.origin
    print("Starting tool", run_meta.creator.instance.name, "with input", run_data.input)


response = await agent.run("What to do in Boston today?").middleware(tool_call_logger)
print(response.last_message.text)

Rules with explanations

Section titled “Rules with explanations”
agent = RequirementAgent(
    llm="ollama:granite4:micro",
    tools=[OpenMeteoTool(), DuckDuckGoSearchTool()],
    instructions="Plan activities for a given destination based on current weather and events.",
    requirements=[
        ConditionalRequirement(
            DuckDuckGoSearchTool,
            only_after=[OpenMeteoTool],
            min_invocations=1,
            max_invocations=2,
            reason="can be used only after retrieving the weather forecast",
        ),
    ],
)


response = await agent.run("What to do in Boston today?")
print(response.last_message.text)

🛠️️ Other improvements:

Section titled “🛠️️ Other improvements:”
  • middlewares: add custom message formatter to the GlobalTrajectoryMiddleware
  • tools: remove next_step from the ThinkTool
  • tools: correctly clone the HandoffTool
  • tools: improve OpenAPITool (#1284)
