Framework integration lock

Pinned third-party versions are enforced in CI via optional dependency installs. Import paths below must remain importable when those extras are installed.

CrewAI

• Packages: crewai (see pyproject.toml [project.optional-dependencies].crewai).
• Hook surface: crewai.hooks.before_tool_call — register a global hook for the duration of agentskeptic.verify().
• Trust boundary: before_tool_call (parameters visible before tool side effects).
• Rejected alternatives: crew-scoped decorators only (we use global registration scoped by context manager lifetime).

LangGraph (Python)

• Packages: langgraph, langchain-core (optional extra langgraph).
• Hook surface: Wrapped checkpointer — subclass/wrapper delegating to the user’s BaseCheckpointSaver and capturing (thread_id, checkpoint_ns, checkpoint_id) on put / put_writes when available.
• Trust boundary: after checkpoint materialization (same tuple as persisted checkpoint).
• Rejected alternatives: ToolNode monkeypatch; requiring users to edit every @tool body.

Version pins (minimum tested)

Package	Minimum
crewai	0.80.0
langgraph	0.2.0
langchain-core	0.3.0

AutoGen integration was removed in AgentSkeptic Python 2.0; a future release may reintroduce it with pinned upstream versions and tests.
