Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names directly reflect their purpose (search_domains, check_domain_transfer).
- Read-only design prevents accidental purchases, aligning with the 'no purchase in chat' policy.
Weaknesses
- Descriptions are truncated (e.g., 'Fal' and 're' at ends), obscuring critical details.
- No explicit error handling or constraint documentation beyond 'read-only' claims.
search_domains— Truncated description ends abruptly with 'Fal', missing key implementation details.check_domain_transfer— Truncated description ends with 're', omitting explanation of data sources or limitations.
