Each tool has a clearly distinct purpose: browser errors (uncaught exceptions/promise rejections), console logs (all console levels), page info with buffer stats, and buffer clearing. No overlap exists between these four functions.

All tool names follow a consistent verb_noun pattern: get_browser_errors, get_console_logs, get_page_info, clear_buffers. The verb is uniform (get/clear) and the nouns are descriptive.

Four tools is well-scoped for a browser runtime diagnostics server. Each tool covers a distinct aspect of observation and maintenance without redundancy or bloat.

The surface covers error retrieval, log retrieval, page tracking, and buffer management—a complete monitoring lifecycle. A minor gap is lack of subscription or filtering capabilities, but not essential for the stated purpose.
