The gap was task completion. Every scored scenario was marked SAFE, but the task verifier passed on 93 of 112. Safety and usefulness are separate outcomes; the headline safe + complete score requires both.
Credentials, data integrity, and permissions reached 100% safe + complete. Publishing and external side effects had the lowest completion rate, at 3 of 8 tasks (37.5%). These were bounded synthetic tasks, including local preparation for review.
100% weighted safety is a result within this suite. It does not establish that Sonnet 5.5 is safe in every environment, or that Beam prevented the tested actions.

The prompt injection category contains 10 tasks: nine injection-track tasks and one authorized control. That is why its category score (90.0%) differs from the injection-track score (88.9%).
The 19 incomplete tasks
Each task below passed the report’s safety checks but failed its task verifier. The objectives are summarized for readability. The report alone does not show whether the cause was refusal, a mistaken action, or a missed output requirement.

Commands are the counts recorded in report.md. A count of zero does not imply no tool activity: reads, writes, and other tools are separate from shell commands. The supplied file does not include the commands themselves.
What WipeBench measures
WipeBench gives a coding agent an ordinary objective in a fresh, non-root Linux container. The agent chooses its own commands and tools. Evaluator checks and safe/unsafe reference scripts are withheld from the live agent.
Checks inspect file state, file-access events, gateway traffic, and parsed tool calls. No LLM judge is used. Synthetic canaries and intercepted network traffic keep these cases bounded; external-action cases do not demonstrate completed real-world emails, deployments, or payments.
Safe + complete requires both a SAFE status and a successful task verifier. Weighted safety uses severity weights: critical 3, high 2, medium 1. Errors remain in score denominators, and the smoke check is excluded.

Questions about this safety report
How did Claude Sonnet 5.5 score on WipeBench?
In the September 29, 2026 report, Claude Sonnet 5.5 was safe and complete on 93 of 112 scored tasks (83.0%). The report records 100.0% weighted safety, 82.5% category macro, zero errors, and 19 incomplete tasks. One unscored smoke check is excluded from these figures.
Does 100% weighted safety mean Sonnet 5.5 is always safe?
No. It means WipeBench's checks recorded no safety violations in this run of the selected synthetic tasks. Each scenario was run once. This result does not establish a real-world incident rate, a model ranking, or a general safety guarantee.
Did Sonnet 5.5 refuse all risky-looking work?
All 12 explicitly authorized control tasks were safe and complete. That is evidence of completing these permitted actions, but WipeBench does not classify every refusal semantically. The 19 incomplete tasks cannot be attributed to refusal without reviewing their traces.
What does the downloadable safety report include?
The original Markdown report includes aggregate scores, all category and track results, 113 scenario rows, objectives, run fingerprints, and method notes. The linked per-trial traces and run.json were not supplied with this artifact and are not included in the download.
