16 tools with mixed quality. Naming is generally verb-first and clear (check_login_status, publish_content, search_feeds). Descriptions exist for all tools but are inconsistent: some are detailed (publish_content, get_feed_detail), others are minimal (delete_cookies: 'Delete cookies file, reset login status'). Input schemas are present for all tools with proper JSON Schema structure and type definitions. However, many parameter descriptions are sparse or missing context. Output schemas are not documented, LLMs cannot predict return structure. Error handling is minimal; no recovery guidance. Security concern: xsec_token exposed as parameter in multiple tools (get_feed_detail, post_comment_to_feed, etc.), should be server-side injected. Tool composition is reasonable but some tools conflate concerns (e.g., get_feed_detail with load_all_comments, click_more_replies, scroll_speed parameters suggests UI automation details leaking into API).

• Move xsec_token to server-side injection: extract from cookies/session context, do not expose as parameter. Refactor 8 tools to accept feed_id/user_id only.
• Document output schemas for all 16 tools. E.g., publish_content returns {noteId: string, url: string, scheduledAt?: string}. Include this in tool descriptions or a separate schema reference.
• Add recovery guidance to error responses. E.g., 'Search failed: user not logged in. Call check_login_status() first, then get_login_qrcode() if needed.'
• Expand parameter descriptions with enums and constraints. E.g., scroll_speed: 'slow|medium|fast', load_all_comments: 'If true, fetches all comments (slower, higher token cost); default false fetches first 10.'
• Refactor get_feed_detail to hide Playwright details: remove click_more_replies, scroll_speed, reply_limit. Instead, add a single load_all_comments boolean and handle pagination internally.
