Entire Adapter

Python adapter that lets LangGraph/LangChain and CrewAI agents participate in Entire checkpoint tracking.

It provides:

• EntireCallbackHandler for LangChain and LangGraph callback configs.
• EntireCrewAIListener for CrewAI's event bus.
• Three Entire external-agent binaries:
  • entire-agent-langgraph
  • entire-agent-crewai
  • entire-agent-entire-adapter for backward-compatible generic use.

Why

Custom Python agents often edit files through tools, but their prompt/tool context is easy to lose once the final Git diff lands. Entire Adapter maps framework lifecycle events to Entire hooks so commits can be linked to agent sessions, tool calls, and checkpoint history.

Install

For LangGraph/LangChain:

pip install "entire-adapter[langgraph]"
entire enable --agent langgraph --telemetry=false

For CrewAI:

pip install "entire-adapter[crewai]"
entire enable --agent crewai --telemetry=false

Generic compatibility mode:

entire enable --agent entire-adapter --telemetry=false

For local development from this repo:

pip install -e ".[langgraph,crewai,dev]"

The adapter does not auto-commit your work. Persistent checkpoint metadata is finalized by Entire's existing Git hooks when you commit.

LangGraph / LangChain

from entire_adapter import EntireCallbackHandler

entire = EntireCallbackHandler(agent_label="reviewer")

result = graph.invoke(
    {"prompt": "Refactor the parser"},
    config={"callbacks": [entire]},
)

print(entire.session_id)

EntireCallbackHandler defaults to Entire agent name langgraph. It maps top-level chain start/end, agent actions, LLM output, tool start/end, and tool errors into transcript records and Entire lifecycle hooks.

CrewAI

from entire_adapter import EntireCrewAIListener

entire_listener = EntireCrewAIListener(agent_label="research-crew")

EntireCrewAIListener defaults to Entire agent name crewai. It listens for crew kickoff, agent execution, and tool usage events. Tool completions trigger turn-end so file changes can become checkpoints.

Checkpoint Policies

Use per-tool policies when not every tool should create a checkpoint:

from entire_adapter import EntireCallbackHandler, ToolCheckpointContext

def checkpoint_writes(context: ToolCheckpointContext) -> bool:
    return context.tool_name == "write_file"

entire = EntireCallbackHandler(
    agent_label="repo-editor",
    checkpoint_policy={
        "read_file": "never",
        "write_file": checkpoint_writes,
    },
)

Supported policy names:

always
never
on_success
on_error

Mapping by tool name wins first, then a global policy, then the legacy checkpoint_on_tool_end flag.

Async Hook Dispatch

Synchronous hook dispatch remains the default:

EntireCallbackHandler(hook_dispatch="sync")

For high-volume agents, opt into a bounded background queue:

entire = EntireCallbackHandler(
    hook_dispatch="async",
    async_queue_size=1024,
    flush_timeout=10.0,
)

# Optional explicit drain at process shutdown.
entire.close()

If the async queue fills, non-strict mode warns and skips the hook. strict=True raises instead.

External-Agent Protocol

Entire discovers external agents from executables named:

entire-agent-{name}

This package installs:

entire-agent-langgraph
entire-agent-crewai
entire-agent-entire-adapter

Protocol commands include:

entire-agent-langgraph info
entire-agent-crewai info
entire-agent-entire-adapter info
entire-agent-langgraph parse-hook --hook turn-end < payload.json
entire-agent-langgraph read-transcript --session-ref .git/entire-adapter/sessions/demo.jsonl
entire-agent-langgraph compact-transcript --session-ref .git/entire-adapter/sessions/demo.jsonl

Metadata And Dashboard Labels

Each hook/transcript record includes richer labels for dashboards:

• framework
• agent_label
• display_name
• entire_agent_name
• run_id
• tool_name
• tool_use_id
• checkpoint_policy
• checkpoint_reason

The adapter writes append-only JSONL transcripts outside the worktree when possible:

.git/entire-adapter/sessions/SESSION_ID.jsonl

Entire reads this transcript through the external-agent protocol so reasoning and tool context can be displayed alongside file changes.

Examples

python usage_example.py
python examples/langgraph_repo_editor.py
python examples/langgraph_checkpoint_policies.py
python examples/crewai_multi_agent.py

The CrewAI example requires CrewAI and normal CrewAI LLM configuration.

Graceful Degradation

By default, the adapter never crashes your agent if Entire is unavailable. It logs one warning and continues when:

• entire is not installed or not on PATH
• the current directory is not an Entire-enabled Git repo
• an Entire hook command exits non-zero
• a hook call times out
• an async hook queue rejects work in non-strict mode

Use strict=True if you want those failures to raise.

Verification

Run unit tests:

python -m pytest -q

Run gated Entire integration tests when the Entire CLI is available:

ENTIRE_E2E=1 python -m pytest tests/e2e -q

Build and check the package:

python -m build
python -m twine check dist/*

After running an agent that edits files:

git status
git add .
git commit -m "test entire adapter"
entire checkpoint list --session "$SESSION_ID"

Manual live checkpoint commands are in adapter_live_test/README.md.

Development

python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e ".[langgraph,crewai,dev]"
python -m pytest -q
