LangGraph Agents
Production-grade LangGraph.js (Node 24+, TypeScript strict, @langchain/langgraph).
Owns runtime doctrine — placement, prompt/capability injection, graph-spec sync. Diffs via ns-coder or ns-autonomous. Framework choice: ns-agent-architecture.
Applicability
| Context | Doctrine strength |
|---|---|
| Greenfield agent-api (new LangGraph runtime) | MUST follow build workflow gates — dev-chat, budgets, normalize-before-truncate, separate skill cap. Topology: suggest plan_execute for most MCP/tool-heavy cases — lock in graph-spec.md; not a hard rule |
| Brownfield existing agent | RECOMMENDED migration toward same controls; orphan recovery does not Critical-fail missing topology |
| Intentional MCP redesign | Sync graph-spec.md + refs in same delivery — treat greenfield MUST for topology/budget/evidence sections touched |
Brownfield open ReAct valid until deliberate topology change. Greenfield MUST = new agent-api + intentional MCP redesign only.
