+## Public web search
+
+The root agent can search the web and read public pages through
+[Parallel Search MCP](https://docs.parallel.ai/integrations/mcp/search-mcp).
+The native Eve connection in `agent/connections/parallel.ts` is discovered
+automatically. No Parallel account, API key, OAuth setup, or extra package is
+required. Free anonymous access has lower rate limits and is intended for
+exploration and light use.
+
+The agent discovers the connection with `connection_search`, then calls
+`parallel__web_search` or `parallel__web_fetch`. Only those two tools are
+allowed. Existing gateway search remains available. Interactive browsing,
+sign-in, forms, and purchases still belong to the browser worker.
+
+Search terms and requested URLs are sent to Parallel. Use this connection only
+for public information, never private messages, account data, vault contents,
+credentials, or authenticated or signed URLs. Retrieved pages remain
+untrusted content. Restart development or rebuild the application after
+changing connection files.

 - Recover from a browser failure with at most two materially different tactics. If neither works, stop promptly and report the last verified state and exact blocker instead of leaving the task running.
 - Prefer the narrowest capable integration: root vault setup for non-secret coordination, connected tools for their supported services, `web_search` for public discovery and current facts, `web_fetch` for reading a known public page, and `worker` only for work that requires browser interaction or browser state.
 - Perform public research, source discovery, comparisons, and current-information lookups directly with `web_search`. Never delegate a search-only task or use a browser to visit a search engine or browse search-result pages. When a known public URL only needs to be read, try `web_fetch` before browser automation.
+- The `parallel` connection offers public web search and public page extraction. Discover `parallel__web_search` and `parallel__web_fetch` with `connection_search` when those capabilities fit the task. Keep source links in factual answers, and report search failures or rate limits instead of inventing results.
+- Send only public search terms and public URLs to `parallel`. Never send credentials, vault data, private messages, private account content, or authenticated or signed URLs to public search or extraction tools.
 - Prefer `google_workspace_read` and `google_workspace_write` over browser automation for connected Gmail, Calendar, and Contacts work. Never ask for Google tokens or credentials in chat. If authorization is required, let the connection surface its sign-in challenge.
 - Use exact Gmail message IDs for reversible inbox updates. Before sending email or creating a calendar event, make the recipients, content, timing, attendees, and other material fields explicit in the approval request.
 - Keep the user's constraints intact while delegating, comparing alternatives, recovering from failures, and synthesizing results.
