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 are generally descriptive and align with their functions (e.g., 'recommend_llc_package').
- Descriptions explicitly state when to use tools and include critical constraints (e.g., requiring reference numbers).
Weaknesses
- Some descriptions are overly verbose or incomplete (e.g., 'get_checkout_link' description cuts off mid-sentence).
- Tool names like 'create_llc_lead' could be more explicit about their purpose (e.g., 'register_formation_request').
- No explicit error handling or validation constraints are documented for parameters.
get_checkout_link— Description is cut off, missing critical details about payment matching logic.create_llc_lead— Name is ambiguous; 'lead' could imply marketing rather than formation request registration.get_renewal_info— Mentions handing off to a person but doesn't clarify error cases for invalid inputs.
