# langgraph - Doramagic AI Context Pack > Purpose: pre-work context for the user's host AI. This pack does not prove that the project has been installed, run, or validated. ## Project - canonical_name: `langchain-ai/langgraph` - capability: Build resilient agents. - expected_user_outcome: Build resilient agents. ## Operating Boundaries - Do not claim that the project has been installed, run, called through an API, or used on local files unless separate evidence proves it. - Project facts must come from repo evidence, Claim Graph, or explicit source references. - When a capability is not verified, mark it as unverified instead of completing it as fact. - publish_status: `publishable` - blocking_gaps: none --- ## Doramagic Context Augmentation The following sections strengthen the repository context for a host AI. Human Manual data is a reading route, and pitfall notes become operating constraints. ## Human Manual Outline Usage rule: this is only a reading route and salience signal, not factual authority. Concrete claims must still return to repo evidence or Claim Graph. Host AI hard rules: - Do not treat page titles, section order, summaries, or importance values as factual project evidence. - When explaining the Human Manual outline, state that it is only a reading route or salience signal. - Capability, installation, compatibility, runtime state, and risk claims must cite repo evidence, source paths, or Claim Graph. - **Core Graph Construction and Runtime**: importance `high` - source_paths: libs/langgraph/langgraph/graph/state.py, libs/langgraph/langgraph/pregel/main.py, libs/langgraph/langgraph/pregel/_algo.py, libs/langgraph/langgraph/channels/base.py, libs/langgraph/langgraph/graph/message.py - **Prebuilt Agents, Tools, and Common Errors**: importance `high` - source_paths: libs/prebuilt/README.md, libs/prebuilt/langgraph/prebuilt/chat_agent_executor.py, libs/prebuilt/langgraph/prebuilt/tool_node.py, libs/prebuilt/langgraph/prebuilt/tool_validator.py, libs/prebuilt/langgraph/prebuilt/interrupt.py - **Checkpointing, Serialization, and Stores**: importance `high` - source_paths: libs/checkpoint/README.md, libs/checkpoint/langgraph/checkpoint/base/__init__.py, libs/checkpoint/langgraph/checkpoint/serde/_msgpack.py, libs/checkpoint/langgraph/checkpoint/serde/jsonplus.py, libs/checkpoint-sqlite/README.md - **CLI, Python SDK, and Deployment Workflows**: importance `medium` - source_paths: libs/cli/README.md, libs/cli/langgraph_cli/cli.py, libs/cli/langgraph_cli/config.py, libs/sdk-py/README.md, libs/sdk-py/langgraph_sdk/__init__.py ## Repo Inspection Evidence - repo_clone_verified: true - repo_inspection_verified: true - repo_commit: `e05ba2965db5373c14ada7ddb3740d9b59a28206` - inspected_files: `README.md`, `docs/redirects.json`, `docs/generate_redirects.py`, `examples/README.md`, `examples/chatbot-simulation-evaluation/simulation_utils.py` Host AI hard rules: - Without repo_clone_verified=true, do not claim that the source code has been read. - Without repo_inspection_verified=true, do not write README, docs, or package-file conclusions as facts. - Without quick_start_verified=true, do not claim that the Quick Start path has run successfully. ## Doramagic Pitfall Constraints These rules come from Doramagic discovery, validation, or compilation findings. The host AI must treat them as operating constraints, not background notes. ### Constraint 1: Security or permission risk requires verification - Trigger: Project evidence flags a security or permission risk. Review the linked source before relying on this workflow. - Host AI rule: Reproduce the official install and quickstart path in an isolated environment. - Why it matters: May increase setup, validation, or first-run risk for the user. - Evidence: community_evidence:github | cevd_23c4b9aa6f6b4875a15c0b250353c3e2 | https://github.com/langchain-ai/langgraph/issues/6987 - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 2: Installation risk requires verification - Trigger: Project evidence flags a installation risk.
