Issue Content

AgentState currently has is_last_step and remaining_steps marked as required (inherently w/ typed dict). Please mark as NotRequired (from typing_extensions).

🤖 Plan Generated

I've generated a plan for this issue and will proceed to implement it since auto-accept is enabled.

Plan: Fix AgentState to use NotRequired for is_last_step and remaining_steps managed values

  • Task 1:
**Update imports in `/home/daytona/langgraph/libs/prebuilt/langgraph/prebuilt/chat_agent_executor.py`** to include `NotRequired` from `typing_extensions` (line 37) by changing `from typing_extensions import Annotated, TypedDict` to `from typing_extensions import Annotated, NotRequired, TypedDict`
  • Task 2:
**Modify the `AgentState` TypedDict class in `/home/daytona/langgraph/libs/prebuilt/langgraph/prebuilt/chat_agent_executor.py`** (lines 68-70) to mark `is_last_step` and `remaining_steps` as `NotRequired` by changing:
- `is_last_step: IsLastStep` to `is_last_step: NotRequired[IsLastStep]`
- `remaining_steps: RemainingSteps` to `remaining_steps: NotRequired[RemainingSteps]`
  • Task 3:
**Add the missing `is_last_step` field to `AgentStatePydantic` class in `/home/daytona/langgraph/libs/prebuilt/langgraph/prebuilt/chat_agent_executor.py`** (after line 78) as an optional field with a default value: `is_last_step: Optional[bool] = None`, and update the import to include `Optional` from typing
  • Task 4:
**Update the docstring and validation logic in `/home/daytona/langgraph/libs/prebuilt/langgraph/prebuilt/chat_agent_executor.py`**:
- Change the docstring on line 394 from "Must have `messages` and `remaining_steps` keys." to "Must have `messages` key. May optionally have `remaining_steps` and `is_last_step` keys."
- Remove `"remaining_steps"` from the `required_keys` set on line 485, leaving only `{"messages"}`
  • Task 5:
**Run formatting, linting, and tests in the prebuilt library directory** by executing:
- `cd /home/daytona/langgraph/libs/prebuilt`
- `make format`
- `make lint`
- `make test`

Proceeding to implementation...
