Integrate A2A with agent frameworks — Google ADK, LangGraph, CrewAI, AutoGen, AWS Bedrock AgentCore, and Microsoft Azure AI Foundry. Use when connecting framework-built agents to the A2A protocol for inter-agent communication.
Implement the AP2 human-not-present transaction flow — autonomous agent shopping with Intent Mandate authorization, constraint enforcement, and merchant escalation. Use when building autonomous agent purchasing that works after the user has left.
Implement and consume the NLWeb /ask REST endpoint — request shape (GET/POST, query-string and v0.55 structured body), SSE streaming response, modes (list/summarize/generate), in-stream "message_type" headers, error envelopes, and client-side parsing. Use when building an NLWeb server route, calling /ask from a custom agent, or debugging /ask responses.
Configure NLWeb authentication and multi-tenant deployments — OAuth providers (GitHub, Google, Microsoft, Facebook), session storage, the `sites:` allowlist in `config_nlweb.yaml`, conversation persistence per authenticated user, and per-tenant data isolation. Use when adding login to an NLWeb instance, hosting multiple customers on one deployment, or persisting conversation history.
Integrate NLWeb with ChatGPT's Apps SDK — the Node.js MCP server in `openai-apps-sdk-integration/`, the `nlweb-list` tool, the React widget at `ui://widget/nlweb-list.html`, and the port-8100 AppSDK adapter that translates NLWeb's message list to OpenAI Apps SDK envelopes. Use when publishing an NLWeb site as a ChatGPT app or wiring NLWeb results into an Apps SDK widget.
Ingest site content into NLWeb's vector store using `db_load.py` — supports RSS/Atom feeds, Schema.org JSON-LD, sitemap-driven URL lists, and CSV. Covers chunking, embedding computation, site partitioning, batch sizing, delete-and-reload, and per-backend write_endpoint targeting. Use when bootstrapping a site's index, refreshing content, or migrating between retrieval backends.
Deploy NLWeb to production — Azure App Service (`deploy_azure_webapp.sh` + AI Search + Azure OpenAI), Snowflake Container Services, Cloudflare Worker + AutoRAG, Docker, and self-hosted. Covers env-var conventions, `mode: production` lockdown, scaling, TLS, OAuth, and CI for data reloads. Use when going from local dev to a hosted, internet-facing NLWeb instance.
NLWeb development patterns — the mixed-mode programming philosophy, FastTrack vs Analysis parallel paths, config file precedence and the `mode: development` override trap, in-stream NLWS headers vs HTTP headers, embedding/ingest determinism, debugging the LLM-call chain, neural scorer selection (NLWebScorer ModernBERT+GAM), and the A2A / AgentFinder / DataFinder / ModelRouter subsystems. Use when designing the internal architecture of an NLWeb deployment or solving cross-cutting concerns.
