Tabrix exposes 18 browser automation tools with significant definition gaps. Most tools have descriptions (good), but parameter documentation is sparse and inconsistent. Many tools lack descriptions for their input parameters, critical for LLM understanding. Schemas are present but incomplete: parameters often lack type constraints, enums, and validation guidance. No output schemas are documented. Error handling is minimal. Tool naming follows verb_noun convention (chrome_click, chrome_navigate) but some names are generic (chrome_execute_javascript). The flow.* dynamic tools are inferred rather than explicitly registered, capping their scores at 50. Overall, the server provides functional automation but falls short of production-grade definition quality.

• Add descriptions to every input parameter. For chrome_click, document 'selector' as 'CSS selector of element to click (e.g. button.submit, #login-btn)' and 'x'/'y' as 'Pixel coordinates relative to viewport (0-based, optional if selector provided)'.
• Document output schemas for all tools. Example: chrome_read_page should return {content: string, visibleRegions?: Array<{selector, text, bounds}>, networkActivity?: Array<{url, status, duration}>}.
• Add numeric constraints to parameters. For chrome_click x/y, specify 'number, 0-9999 pixels'. For flow.* timeoutMs, specify 'number, minimum 0, default 30000'.
• Rename chrome_execute_javascript to chrome_execute_js_unsafe or add a prominent warning in the description: 'IRREVERSIBLE: Executes arbitrary JavaScript in the page context. Use only when other tools cannot accomplish the task. Cannot be undone.'
• Explicitly register flow.* tools in code with full schemas rather than inferring them. Include parameter definitions for all configurable variables, not just tabTarget/refresh/captureNetwork.
