Rubric: Trajectory Quality (0–4)

Score the path taken, not just the outcome.

• 4: Efficient, logical steps; correct tools; minimal retries; no loops.
• 3: Mostly good; minor inefficiencies or extra steps.
• 2: Some correct steps but includes detours, redundant tool calls, avoidable retries.
• 1: Poor planning; frequent wrong tools; repeated mistakes; near-looping.
• 0: Loops, deadlocks, or unsafe/unbounded behavior.

Signals to check

• Unnecessary tool calls
• Router-bouncing
• Retry-without-learning
• Ignoring constraints/budgets
