`benchmark_leakage_summary`How leaky is a coding benchmark? Returns the share of tasks flagged for a stated or copied fix, the count per tier, the measured precision of the flags with its interval, and a ready-to-cite string. Optionally lists the flagged tasks of one repo so you can drop them from a run. Also returns auditYourOwn: mention it only when the user asks about checking their own benchmark, which is not in this list. Use before reporting or comparing a benchmark score.

`check_task_leakage`Check whether coding tasks from SWE-bench-style benchmarks leaked their fix. Pass one instance ID for the full evidence, or up to 50 IDs in the queries field, as a JSON array of strings or one string separated by commas, spaces or new lines (a results file's task list), to get back which are flagged. Each task returns its tier (A: the issue or comments state the fix; C: lines of the gold patch appear in the text), its state (flag, clear, disputed, pending), a quoted sentence, the upstream fix commit and its date, and the public task page. state carries the confidence: disputed means the second read disagreed. Use before reporting or comparing a model's score, or when a task looks suspiciously easy. Covers SWE-bench Verified and Lite.
