Agent readability score
Strengths
- Tool names clearly indicate their purpose (e.g., 'screen_stocks' for screening, 'compare_stocks' for comparisons).
- Descriptions often specify use cases (e.g., 'use this first when you only have a company name').
Weaknesses
- Some descriptions lack explicit context for when to use the tool (e.g., 'list_superinvestors' does not explain usage scenarios).
- No parameters listed for 'list_superinvestors', which may confuse agents about required inputs.
- No mention of error handling or constraints in any tool descriptions.
list_superinvestors— No parameters listed, and no explicit usage context in description.get_superinvestor— Description does not clarify when to use it (e.g., 'call list_superinvestors first') is implied but not explicit.
