Tool guidance sections keep only what the tool definitions do not say. Apply review: reword interrupt_agent and list_agents, carry "a rejected escalation stays denied" in the rejection error, pin sandboxPermissionsDescription, and fix stale README and Agent Note statements. Record the tool-definition rules in agent-experience. Compaction threshold snapshots shift their context windows by the 370-token system-prompt estimate reduction; escalation-rejected moves to a v4 fixture for the new rejection text.

| 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/ packages let models search the public web and fetch HTTP(S) pages through the web_search and web_fetch tools. Deployments can choose Exa, Perplexity, or DeepSeek for search and anonymous HTTP(S) access for fetch; availability and resource limits depend on the configured provider. Use this family for search and page retrieval, not interactive browsing, content extraction, or per-URL policy enforcement. Models receive consistent tool behavior, cancellation, and error reporting when providers change.
