This server has moderate definition quality with significant gaps. All 10 tools are explicitly defined with descriptions and schemas visible in server.py. However, descriptions vary widely in quality, some are well-detailed (boss_search_candidates, boss_multi_search) while others are minimal. Parameter descriptions are generally present but inconsistent. Schema quality is uneven: some tools have rich input schemas (boss_search_candidates, boss_multi_search, boss_update_candidate) while others have empty or minimal schemas (boss_login, boss_get_stats). No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present despite clear risk profiles. Error handling is present but not comprehensive, some tools return verification screenshots on failure, but actionable recovery guidance is limited. The server operates in Chinese, which may complicate LLM understanding of intent without translation.

• Add tool annotations (readOnlyHint/destructiveHint/idempotentHint) to all tool definitions. Explicitly set readOnlyHint=true for read-only tools, destructiveHint=true for boss_clear_dedup, write operations for boss_login and boss_update_candidate.
• Document output schemas for all tools. Create explicit return_type or output_schema objects showing field names, types, and descriptions. For example, boss_search_candidates should return {candidates: [{expectId: string, name: string, ...}], _stats: {total_fetched: integer, new: integer, ...}}.
• Add min/max constraints to numeric parameters: count (1 - 500), count_per_keyword (1 - 200), limit (1 - 100), evaluation_score (0 - 100 via enum or min/max).
• Convert free-form enum parameters to formal enums: status in boss_clear_dedup and boss_update_candidate should list all valid values (new, legacy, interested, rejected, contacted, interview, offer, etc.) as JSON Schema enums.
• Add format: 'date' constraint to date parameters (before_date, date_from) and update schema to use type: 'string', pattern: '^\d{4}-\d{2}-\d{2}$' or format: 'date'.
• Add dry_run flag to boss_clear_dedup to prevent accidental data loss. Document reversibility or provide recovery guidance if dry_run is false.
• Enhance error handling with actionable recovery messages. When a search fails due to CAPTCHA, provide explicit next steps: 'Verification required. The browser is waiting for user interaction. Complete CAPTCHA in the browser window, then retry the search.'
• Add explicit prerequisite language to dependent tools. boss_view_by_index description should state: 'Prerequisites: Call boss_search_candidates() or boss_multi_search() first to populate the search result index.'
