(NS) LangGraph.js agent-api — greenfield scaffold (bootstrap-agent-runtime), StateGraph, MCP tools, skill bind/inject, checkpointers, context-window trim, HITL/SSE, prompt/locale placement. Use for new agent-api from scratch, LangGraph graphs, MCP wiring, orphan layout, system-prompt compose, bind parity, graph-spec sync, or "fix my LangGraph agent" / "wire MCP tools" / "translations in the graph". Feature diffs via ns-coder; version features via ns-spec-driven; LangGraph vs CrewAI via ns-multi-agent-architect. Do NOT use for CrewAI crews, generic web apps, or SDD-only requirements with no agent-api.
Builds and improves Browserbase Agent API demos through an Autobrowse-style outer loop: run a fixed task, collect Agent messages and session logs, score the result, revise one system-prompt heuristic, and confirm convergence. Use when creating a Browserbase Agents demo or POC, optimizing an Agent system prompt, diagnosing flaky Agent runs, or applying auto-research/autobrowse to the Browserbase Agents API.
Use when an agent wants to access Alchemy APIs without an API key. This is the default path when $ALCHEMY_API_KEY is not set. Covers SIWE authentication, x402 payment flows, wallet setup, and gateway endpoints.
