agent-contracts Tool Use / RAG

Use this skill when your nodes call external services (DB, search, HTTP APIs) or do retrieval-style work.

Core Ideas

• Declare dependencies in NodeContract.services (and requires_llm when needed).
• Inject dependencies via:
  • direct node construction (node_cls(llm=..., my_service=...)), or
  • dependency_provider in build_graph_from_registry(...).
• Keep LLM routing context small; rely on sanitization and context_builder only when needed.
