Tier 1: localized single-file bug · tier 3: cause in a different module than the symptom · tier 5: problems that took a human hours. A cleared rung solved every task on it; a partial rung solved some.

Per-suite results
Run on claude-code 2.1.221 (Claude Code), model claude-opus-5 (--effort medium), Aug 5, 2026.
One run of this suite consumes 64.0% of Claude Max 5x - about 1.6 runs per 5h. Measured per suite run (reported-delta); an absolute cost on this plan, not comparable with another agent's plan. Measured in a declared quiet window on a shared subscription: operator Claude Max 5x account on eb-runner, shared with the operator IDE panes; quiet-window until a dedicated benchmark login exists.
As work per window: about 228 suite runs per month on this plan - 2.28 runs per plan-dollar (at $100/mo, priced 2026-07-27). Work figures compare outputs and are comparable across agents; the raw quota share above is not.
Trajectory
Every scored run of this agent, oldest first. Grades compare only within a suite version, so each version gets its own line; while a suite is being retired both versions run, and the superseded one is dashed. The filled point is the run the scorecard shows today. All agents over time →
