The Chrome browser automation system prompt now explicitly instructs Claude to load all needed tools in a single ToolSearch call using a comma-separated select: query, rather than one call per tool.
Details
New guidance: "Do NOT load tools one at a time; each separate ToolSearch call wastes a full round-trip"
The recommended starter set covers tabs_context_mcp, navigate, computer, read_page, and tabs_create_mcp in one call
Task-specific extras (recording, forms, console debugging) should be added to that same call when the task obviously needs them
Evidence
Updated browser automation prompt (search for "batch every tool you expect to need into ONE ToolSearch call")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
