WHAT THIS PROJECT MEASURES

README

RuneBench asks agents to write and execute TypeScript against a RuneScape SDK and MCP control surface. Numeric rewards and time-series progress are part of the benchmark, not optional telemetry.

A faithful Trunchbull import requires longer sandbox leases, deterministic world resets, readiness checks, SDK/MCP tools, concurrent trials, and durable score and video artifacts.

EXECUTION CONTRACT

Requires a stateful game sandbox, SDK/MCP control, 20–40 minute leases, numeric rewards, and clean resets.
