# langgraphjs - 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/langgraphjs` - capability: LangGraph - expected_user_outcome: LangGraph ## 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 Framework: StateGraph, Channels & Pregel Runtime**: importance `high` - source_paths: libs/langgraph-core/src/graph/state.ts, libs/langgraph-core/src/graph/graph.ts, libs/langgraph-core/src/graph/annotation.ts, libs/langgraph-core/src/graph/messages_reducer.ts, libs/langgraph-core/src/channels/index.ts - **Persistence, Checkpointing & Long-Term Memory**: importance `high` - source_paths: libs/checkpoint/src/base.ts, libs/checkpoint/src/memory.ts, libs/checkpoint/src/store/base.ts, libs/checkpoint/src/serde/jsonplus.ts, libs/checkpoint/src/types.ts - **SDK, API Server, CLI & Frontend Framework Integrations**: importance `high` - source_paths: libs/langgraph-api/src/server.mts, libs/langgraph-api/src/api/runs.mts, libs/langgraph-api/src/api/threads.mts, libs/langgraph-api/src/api/assistants.mts, libs/langgraph-api/src/api/store.mts - **Streaming Protocols, Prebuilt Patterns & Multi-Agent Ecosystem**: importance `high` - source_paths: libs/langgraph-core/src/stream/index.ts, libs/langgraph-core/src/stream/stream-channel.ts, libs/langgraph-core/src/stream/transformers/index.ts, libs/langgraph-core/src/stream/run-stream.ts, libs/langgraph-core/src/stream/convert.ts ## Repo Inspection Evidence - repo_clone_verified: true - repo_inspection_verified: true - repo_commit: `e6082e05755797a92e9d24149496923e044319ee` - inspected_files: `README.md`, `package.json`, `pnpm-lock.yaml`, `docs/_scripts/copy_notebooks.py`, `docs/_scripts/generate_llms_text.py`, `docs/_scripts/notebook_convert.py`, `docs/_scripts/notebook_convert_templates/mdoutput/conf.json`, `docs/_scripts/notebook_hooks.py`, `docs/_scripts/third_party/__init__.py`, `docs/_scripts/third_party/create_third_party_page.py`, `docs/_scripts/third_party/get_download_stats.py`, `docs/_scripts/third_party/packages.yml`, `docs/docs/adopters.md`, `docs/docs/agents/agents.md`, `docs/docs/agents/context.md`, `docs/docs/agents/deployment.md`, `docs/docs/agents/evals.md`, `docs/docs/agents/human-in-the-loop.md`, `docs/docs/agents/mcp.md`, `docs/docs/agents/memory.md` 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: Identity risk requires verification - Trigger: Project evidence flags a identity 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: identity.distribution | https://www.npmjs.com/package/@langchain/langgraph - 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. 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 | https://github.com/langchain-ai/langgraphjs/issues/2496 - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 3: Capability evidence risk requires verification - Trigger: README/documentation is current enough for a first validation pass. - 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: capability.assumptions | https://www.npmjs.com/package/@langchain/langgraph - Hard boundary: Do not present this pitfall as solved, verified, or ignorable unless later evidence explicitly closes it. ### Constraint 4: Runtime risk requires verification - Trigger: Project evidence flags a runtime risk.
