DeepAgents Compatibility Example

Source:

• examples/langchain/deepagents_graph.py

This example is the maintained DeepAgents-facing showcase for langchain-acp.

It demonstrates:

• a Codex-backed ChatOpenAI model created through codex-auth-helper
• wiring a DeepAgents graph through langchain-acp
• DeepAgentsCompatibilityBridge
• DeepAgentsProjectionMap
• tool-based plan compatibility through write_todos
• approval-gated file writes

Install the optional dependency first:

uv add "langchain-acp[deepagents]"

pip install "langchain-acp[deepagents]"

Run it:

uv run python -m examples.langchain.deepagents_graph

Required local state:

~/.codex/auth.json

If you want the module-level compiled graph directly, the example exports graph when deepagents is installed:

acpkit run examples.langchain.deepagents_graph:graph

If deepagents is not installed, use the module as a recipe and keep main() or graph_from_session(...) as the entrypoint instead.
