Exposes an agent skill debugging lab over MCP, letting an agent record model calls at the proxy, find the step where successful and failed runs diverge, fork and resample that step, and A/B test skill wording edits with confidence intervals and significance tests. It also enables live breakpoints, workspace snapshots, end-to-end restart of a recorded run, and token-level analysis of which token decided a step.
