TDQS

A3.7/5.0

Scored across 5 tools

Disambiguation4/5

The core flow is clearly separable: calculate_tax_credit computes, verify_tax_credit_result checks a hash, list_rule_packs enumerates credits, and get_rule_pack fetches one pack. The only soft overlap is describe_agent, whose capability/pricing role is partly duplicated by the payment boilerplate embedded in calculate_tax_credit's description.

Naming Consistency5/5

All five names use a clean snake_case verb_noun pattern (calculate_, describe_, get_, list_, verify_), with plural/singular handled predictably (list_rule_packs vs get_rule_pack). No camelCase mixing or vague verbs.

Tool Count5/5

Five tools is well matched to a narrow computational engine: one compute tool, one verifier, two rule-pack lookups, and one metadata tool. Nothing feels padded or missing at the surface level.

Completeness4/5

The audit lifecycle is covered end to end: list rule packs, fetch a pack, calculate, then verify the result hash. Minor gaps remain—no batch calculation and no dedicated tool to surface the required fact schema per credit other than the rule packs themselves.
