Single tool 'chrome_call' has a reasonable schema with three typed parameters (namespace, method, args), but critical gaps undermine quality. Description is only 79 chars, below the 194-char baseline and lacks WHEN/WHY context. Parameters lack individual descriptions (namespace, method, args are named but not explained). No output schema documented. No error handling guidance. Tool name 'chrome_call' is generic and does not follow verb_noun convention (should be 'call_chrome_api' or similar). No indication of what the tool returns or how to chain results. Risk marked READ_ONLY but no idempotent/destructive hints in schema.

• Rename 'chrome_call' to 'invoke_chrome_extension_api' or 'call_chrome_api' to follow verb_noun convention and clarify intent.
• Expand tool description to 150 - 250 characters explaining: (1) what it does (invokes Chrome extension APIs), (2) when to use it (when you need to interact with browser tabs, windows, bookmarks, etc.), (3) what it returns (the result of the Chrome API call).
• Add descriptions to each parameter: namespace ('Chrome API namespace, e.g., "tabs", "windows", "bookmarks"'), method ('Method name within the namespace, e.g., "query", "create"'), args ('Array of arguments to pass to the Chrome API method').
• Document the output schema: describe the structure of the response (e.g., 'Returns the result of the Chrome API call as a JSON object, or an error object with message and code fields on failure').
• Add error handling guidance: 'If the Chrome extension is not installed or the API call fails, returns an error object. Verify the namespace and method are valid Chrome APIs before retrying.'
