The server defines 3 tools with complete input schemas and descriptions, but quality varies. All tools start with action verbs (read_, open_, list_) which is good. However, descriptions are functional but generic (10-100 chars), and lack LLM optimization details like when to use each tool, prerequisites, and dependencies between them. The read_article and open_article tools have nearly identical parameters and similar descriptions, creating confusion about their distinct use cases. Parameter descriptions are present but minimal. Output schemas are not documented anywhere in the visible code, which violates the 'documented return types' baseline (100% of A+ tools have this). Error handling is mentioned as a feature but not visible in the code sample provided.

• Clarify the distinction between read_article and open_article in their descriptions. E.g., 'read_article: Fully extract and return the article content (title, author, body, metadata). Slower but complete.' vs 'open_article: Open the article URL in the browser and return current page status without waiting for content extraction. Useful for verification or real-time page interaction.'
• Document complete output schemas for each tool. Show the exact fields returned, their types, and nesting. E.g., for read_article: { title: string, author: string, content: string, publish_date: ISO8601, ... }
• Expand parameter descriptions to 50-150 characters. Explain the impact of each choice. E.g., strategy: 'How to connect to the browser. auto=detect running instance; attach=use explicit cdp_url; launch=start new process; playwright=use Playwright managed browser. Most common: auto.'
• Add dependency hints to tool descriptions. E.g., 'Before calling this tool, ensure a browser is running or pass strategy=launch. If manual WeChat verification is needed, set wait_for_manual_verify > 0.'
• Document enum options in parameter descriptions. E.g., 'strategy (required): auto | attach | launch | playwright. auto attempts to find a running browser; launch starts a new one if none found.'
• Specify realistic ranges for numeric parameters. E.g., 'timeout (seconds): 1-300, recommended 30-60. If exceeded, returns timeout error with retry guidance.'
• Add explicit error guidance to tool descriptions. E.g., 'May fail if: browser not running (suggest retry with strategy=launch), WeChat blocks access (suggest wait_for_manual_verify=90), or network unavailable. See error message for next steps.'
