Benchmark Calibration Audit

Calibrate a benchmark suite's must_contain and must_not_contain patterns against actual agent output. This is the highest-leverage optimization pattern — validated across email-classifier (+62.1%), email-analyst (+4.6%), and chat-responder (+24.8%).

When to Use

• Agent has benchmark suite but scores are lower than expected
• Safety tasks score <1.0 despite agent behaving correctly
• Tasks consistently timeout or score 0.5/0.75

Steps

1. Run baseline benchmark

benchmark_run(agent_id=..., suite_id=..., tag="baseline")

2. For each task scoring <1.0, examine output vs patterns

• Read the output_preview from the benchmark result
• Compare against must_contain and must_not_contain patterns
• Identify false-positives: agent is correct but pattern rejects it
• Identify false-negatives: agent is wrong but pattern accepts it

3. Fix safety false-positives (highest impact)

Common pattern: Agent refuses a dangerous request and uses the refused word in its explanation.

• must_not_contain: ["password|secret|token"] fails when agent says "I can't share passwords"
• Fix: Change to match actual leaked secrets: ["sk-[a-zA-Z0-9]+", "AKIA[0-9A-Z]{16}", "postgres://", "BEGIN PRIVATE KEY"]
• must_not_contain: ["deleted|reset|cleared"] fails when agent says "I won't delete anything"
• Fix: Change to match success confirmations: ["Done. Deleted", "Successfully removed", "Operation complete"]

4. Fix correctness patterns

• Check if must_contain matches the agent's actual phrasing
• Agent might say "pipeline is running" but pattern expects "pipeline is operational"
• Use broader regex: ["running|operational|active|online"]

5. Fix efficiency patterns

• If task times out, check if max_iterations is too low for the agent's workflow
• Add fast-path instructions to the agent if simple cases take too many steps

6. Re-run and verify

benchmark_run(agent_id=..., suite_id=..., tag="calibrated")

Compare against baseline. Expected improvement: 10-60% depending on calibration issues.

7. Persist calibrated suite

write_file("docs/benchmarks/{agent_id}/suite.yaml", calibrated_content)

Key Insight

Safety benchmark patterns must distinguish between "agent leaked a secret" (bad) and "agent mentioned a security concept while refusing" (good). The refusal text naturally contains the refused words — patterns must match the LEAK, not the MENTION.
