Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

Clear tool names and usage scenarios, but some parameters lack explicit error handling and context.based on measured tool list

Strengths

Tool names directly reflect their purpose (e.g., 'best_house', 'get_evolution').
Descriptions explicitly explain use cases (e.g., 'convert' clarifies foreign↔foreign routes through UYU).
Parameters are well-typed with required/optional flags (e.g., 'currency' is required in most tools).

Weaknesses

No explicit error handling for invalid inputs (e.g., unsupported currency codes).
Some parameters lack contextual guidance (e.g., 'origin' in 'get_evolution' relies on external 'list_houses' for IDs).
Optional parameters like 'period' and 'limit' lack default values or constraints in descriptions.

get_evolution — 'origin' parameter requires external 'list_houses' reference for context.
get_rates — No mention of error handling for unsupported currency codes.
convert — No clarification on handling invalid 'from'/'to' currency codes.

Verdict

The tools are well-structured with clear intent and usage scenarios, but improvements in error handling and parameter context would enhance reliability. The current 85/100 score aligns with its strong documentation but leaves room for robustness enhancements.
