William FHandGitHub c5b118a672 Add admonitions about managed checkpointers (#4197) 
If you're deploying with langgraph API, you don't need to manually
define a checkpointer. For folks who already know they'll be developing
with the api server, I'd like to save everyone time by making this more
clear in the docs on checkpointing.

Allow the CLI to work with dict format for the graph specification.

```json
{
  "dependencies": ["./my_agent"],
  "graphs": {
    "agent": {
      "path": "./my_agent/agent.py:graph",
      "description": "this is my agent description"
    }
  },
  "env": ".env"
}
```

And backwards compatible with:

```json
{
  "dependencies": ["./my_agent"],
  "graphs": {
    "agent": "./my_agent/agent.py:graph",
  },
  "env": ".env"
}

Nuno Campos 7e08339335 mypy is dumb 2025-04-03 16:55:23 -07:00
Nuno Campos e1d4b5552d Add checkpoint_during arg 
- This provides a new mode of execution where only the last checkpoint is saved
- We save the last checkpoint no matter how the agent run is terminated (success, error, interrupt, etc)
- This cuts down on cpu time spent on checkpointing, while not losing any resilience benefits, given individual task writes are still saved
- If an error occurs and the run is retried, any tasks that completed successfully before will be skipped (as currently)
- checkpoint_during=True is useful when you want to time-travel to inner steps of a run
- The default value will remain the current behavior, ie. checkpoint_during=True
