Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Most tool names clearly indicate their purpose (e.g., 'guestbook_sign', 'job_claim').
- Descriptions often explain usage context (e.g., 'deaddrop_leave' specifies note addressing).
Weaknesses
- Some tool names are vague (e.g., 'leave_your_mark' lacks specificity).
- Parameter types like 'table' in 'tournament_enter' are ambiguous without schema details.
- Error handling and constraints are inconsistently documented.
leave_your_mark— Name does not clearly indicate it stores names for 'who_else_is_here'.tournament_enter— Parameter 'table' is an object but lacks schema definition.
