Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

GST Validator tools are clear but lack explicit input schema details.based on measured tool list

Strengths

Tool names clearly indicate purpose
Descriptions explain usage contexts
Error handling and constraints are documented

Weaknesses

Input parameter types remain ambiguous without schema
extract_pan tool lacks check character validation

extract_pan — Does not verify GSTIN check character

Verdict

Tools are well-structured with clear purposes and error handling. However, input parameter definitions could be more explicit to avoid ambiguity. The extract_pan tool's limited validation scope requires careful pairing with validate_gstin.

Era history

Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
