Loading ToolBench
The server implements 3 tools with basic functionality but suffers from significant gaps in naming clarity, parameter documentation, and error handling guidance. Tool names do not follow the verb_noun pattern (e.g., 'pronostico' instead of 'get_weather_forecast'). Two of three tools have minimal descriptions (19 and 4 characters respectively). Parameter descriptions are present but generic. Output schemas are implicit (returned as text content) rather than explicitly documented. No error recovery guidance is provided, errors return raw messages rather than actionable suggestions. The implementation is functional but falls well short of production quality baselines.

Tool naming does not follow verb_noun pattern. 'pronostico' (Spanish), 'echo', and 'ping' lack clear action verbs, violating Arcade pattern:tool baseline where 90% of A+ tools start with action verbs.
ping tool has zero-character description, triggering HARD CAP: description score MUST be 0. LLMs cannot determine when to call ping vs other tools.
echo tool description is 26 characters, below the 50-character baseline and triggering HARD CAP: description score CANNOT exceed 40. Lacks WHEN/WHY guidance.
Output schemas are undocumented. Tools return text content with no structured schema declaration, forcing LLMs to parse unstructured strings. Violates pattern:response-shaper and pattern:tool baselines (100% of A+ tools have documented return types).

Error messages provide no recovery guidance. 'Error al obtener el pronóstico para ciudad: <error>' does not tell the LLM what to do next (retry, fallback, ask user). Violates pattern:recovery-guide.
No pagination support despite potentially large results. pronostico fetches hourly forecast data that could exceed context limits. No limit, offset, or cursor parameters. Violates pattern:paginated-result.
ping tool should not be exposed as a user-facing tool. It is infrastructure-only and wastes agent reasoning cycles. Should be removed from the tool list or marked as internal.
Language inconsistency: tool descriptions are in Spanish while code is in English. If this is a Spanish-language server, all descriptions should be in Spanish AND English. Creates ambiguity for multilingual agents.
