Run on claude-code 2.1.215 (Claude Code), model claude-haiku-4-5, Jul 19, 2026.

One run of this suite consumes 2.0% of Claude Max 5x - about 50.0 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.

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within a suite version, so each version gets its own line; while a suite is being retired both versions run, and the superseded one is dashed.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 →
