Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their purpose (e.g., lookup_quran_ayah vs search_quran).
- Descriptions explicitly guide usage scenarios (e.g., 'use list_tafsirs before a tafsir lookup').
Weaknesses
- Some parameters (e.g., 'sort', 'books') lack detailed constraints or examples.
- No explicit error handling or validation rules for inputs (e.g., invalid surah/ayah numbers).
search_quran— Parameter 'sort' lacks clarification on valid values.search_hadith— Parameter 'books' does not specify allowed alias formats or constraints.lookup_tafsir— No mention of default language behavior for optional 'language' parameter.
