This is a specialist domain tool server (Baileys/WhatsApp library documentation) with 20 tools. All tools have clear names starting with domain prefix 'whaileys_' and action verbs (extrair, buscar, listar, etc.). Descriptions are present for all tools and range 85-280 characters, meeting the 10-1024 baseline. Input schemas are consistently defined using Zod with proper type annotations. All tools are READ_ONLY and properly annotated with readOnlyHint. However, gaps exist: (1) Output schemas are not explicitly documented in the code, responses are free-form text rather than structured objects, violating the 'document output schema' pattern. (2) Parameter descriptions exist but some are vague (e.g., 'Limite de resultados (default: 20)' lacks explanation of why 20 is default or what 'results' means). (3) No error recovery guidance, tools return isError: true but provide no actionable next steps. (4) No pagination metadata, tools that list items (e.g., whaileys_examples, whaileys_socket_methods) accept limit but return no total_count or next_cursor. (5) Many tools accept optional filters but do not document what happens when both are omitted. Strengths: consistent naming, comprehensive parameter coverage for a documentation server, proper Zod schema usage, and clear categorization of tool families (ast-tools, content-tools, domain-tools, etc.).

• Document output schemas for all tools. Instead of free-form markdown, return structured JSON: e.g., whaileys_buscar_tipo should return { name: string, kind: string, signature: string, properties: { name: string, type: string }[], docs: string }. This enables LLMs to parse and chain results.
• Add total_count and next_cursor to paginated responses. Example: whaileys_buscar_fuzzy should return { results: [...], total_count: 42, limit: 20, offset: 0 } so agents know pagination boundaries.
• Enhance error recovery guidance. When whaileys_buscar_tipo fails, add explicit: 'Suggestion: call whaileys_buscar_fuzzy(query="<term>") for approximate matching.' This guides the agent's next step.
• Clarify optional parameter behavior in descriptions. E.g., whaileys_categorias modulo param: 'If omitted, lists all modules. If specified (e.g., "Socket"), filters to declarations in that module only.'
• Add numeric bounds and constraints to descriptions. E.g., limit parameter: 'Maximum results returned (1 - 100). Default 20. Larger values increase response size and token cost.'
• Define and expose output schema for each tool in inputSchema companion property (future-proofing for OpenAPI export). Use Zod to define return types alongside inputs.
• Add per-tool error examples. Document what happens when modulo is invalid (e.g., 'socket_typo' instead of 'Socket'). Current behavior unclear from description.
• Consider batch variants for tools called in loops. E.g., whaileys_buscar_tipo accepts one nome parameter. If agent needs to look up 5 types, it calls the tool 5 times. Offer whaileys_buscar_tipos_batch([nome1, nome2, ...]) to reduce round-trips.
