replay_span | Fork-replay ONE recorded span from a failed agent run and return an attribution verdict (determinism vs tool drift vs env drift vs world-state vs model decision), without re-running the whole run. params: span, span_id, spans |
fork_safety_check | Examine ONE recorded span (or a run's span set) forensically — canonicalization, env binding, completeness, stub coverage — and return the fork-safety verdict (FORK-SAFE-LIVE / FORK-SAFE-STUBBED / FORK-DEGRADED / FORK-UNSAFE) WITHOUT executing the span or forking anything. $0.01 per span checked on the hosted surface. params: span, span_id, spans |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
