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 (company_snapshot, cve_snapshot) directly indicate their purpose.
- Descriptions explicitly state what they return and avoid scope creep (e.g., 'not financial-statement extraction').
Weaknesses
- Redundant parameters (e.g., max_age_seconds vs max_age) create ambiguity.
- submit_fishnet_feedback has overly complex parameters with unclear usage (e.g., schema_version type 'null').
- Some parameters lack clear constraints or explanations (e.g., 'desired_fields' as both string/array).
company_snapshot— Redundant parameters: max_age_seconds and max_age.cve_snapshot— Redundant parameters: max_age_seconds and max_age.submit_fishnet_feedback— Unclear parameter: schema_version has type 'null'.
