Agent readability score

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

Agent readability score

Tools have clear purposes but lack detailed parameter definitions and error handling.based on measured tool list

Strengths

Some tool names clearly indicate their function (e.g., 'validateOrder', 'createOrder')
Comprehensive coverage of purchase workflow steps

Weaknesses

Ambiguous parameter definitions in multiple tools
Lack of explicit error handling documentation
Some tool names use non-standard terminology ('vias' in 'getPaymentViasWithCurrencies')

getPaymentViasWithCurrencies — Non-standard terminology 'vias' in name
listProductsForCountry — Unclear required/optional parameters in description
searchProducts — Overlaps with listProductsForCountry functionality
validateOrder — No explicit error condition documentation
purchaseElicitation — Session token management details missing

Verdict

Tools provide functional coverage for purchase workflows but suffer from inconsistent naming conventions, insufficient parameter documentation, and missing error handling details. The lack of clear input schema definitions and overlapping functionality between search/list tools creates potential ambiguity for agents.

Event narrative

Server transitioned to legacy era with full compliance (100 score) after auth-gated phase.

Risk: medium

2026-09-10T21:16:35.016Z — era changed from auth-gated to legacy · transition to legacy mode, compliance score initialized
2026-09-11T01:59:45.474Z — compliance score set to 100 · achieved full compliance, no smoke test issues

Advice

Monitor legacy era stability and ensure compliance score remains at 100. Investigate smokeOk null status if it affects system integrity.
