| Package map for the web access capability family: the search/fetch service, its provider backends, and the model-facing tools that consume them. | package-group |
web/ — web access capability family
English | 中文
Summary
The web/ group gives the harness web access — searching the web and fetching URLs — through one provider-neutral service (ctx.web) and the backends and tools that use it. A deployment mounts one or more backends — Exa, Perplexity, or DeepSeek for search, anonymous HTTP(S) for fetch — and the service picks a usable provider per operation, so the model-facing tools stay stable while backends come and go. Six packages split the family: the web/ service that owns provider selection and errors, three search backends, one fetch backend, and tool-web/, which exposes web_search and web_fetch to the model. The group owns web access only: no browsing or extraction, no per-URL policy, and each backend keeps its own resource caps. Search and fetch deliberately share one service so selection, cancellation, errors, and configuration have a single owner.
