Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Some tools (e.g., 'validate-json', 'geo-hint') have clear, specific purposes.
- Diverse functionality covers URL validation, timezones, JSON checks, and more.
Weaknesses
- Tool names are generic and non-descriptive (e.g., 'cc-nr', 'utc-time').
- All parameters are optional with no guidance on relevance or expected values.
- High overlap between tools (e.g., 'browser-url-ok' vs. 'playwright-url-ok') creates ambiguity.
- No error handling or constraints documented in descriptions.
cc-nr— Name does not clearly indicate ISO 3166-1 country code retrieval.utc-time— Description lacks context for when/why to use this tool.timezone— Parameters (e.g., 'zone') are ambiguous without type constraints.web-fetch— Duplicates functionality with 'fetch-status' and 'normalize-url'.
