Measured sandbox verdicts: 7-axis probe, signed pinned receipt. Cached $0.25, fresh $2.50.
Scored across 5 tools
The tools mostly target distinct operations: framework listing, gate evaluation, receipt verification, cached verdict lookup, and watch status. The main overlap is between sandbox_cached_verdict and sandbox_watch_status, since both surface cached verdict information, but their descriptions make the distinction reasonably clear.
All tools share the sandbox_ prefix and use snake_case, giving a predictable namespace. The suffix conventions are slightly mixed—some are noun-like (frameworks, gate, watch_status) while one is verb_noun (verify_receipt)—but the set remains readable and mostly consistent.
Five tools is well-scoped for a focused sandbox truth/probe server. Each tool appears to earn its place by covering discovery, evaluation, verification, lookup, and watch state without obvious padding.
The surface covers the core probe workflow: listing fixtures, evaluating gate conditions, verifying receipts, checking cached verdicts, and viewing watch status. Minor gaps may exist around actively submitting or refreshing a probe/watch, but the essential verification lifecycle is represented.
Look up whether a cached verdict exists (delivery is paid over x402 on the HTTP surface).
