Stable Task identities and signatures

Long-context retrieval

KFA Task ID: benchmark-task-scout-6dc53f0d46d132f135e76727

Source or catalog identity: infinitebench-long-context-retrieval

Evaluate whether an agent can locate a relevant detail in a long supplied context in a context-window evaluation. Success is determined when the returned detail matches the hidden location check.

Long-range consistency

KFA Task ID: benchmark-task-scout-a95f29f864d04c7bd2c7331a

Source or catalog identity: infinitebench-long-range-consistency

Evaluate whether an agent can maintain consistency across distant context segments in an extended sequence evaluation. Success is determined when the final answer respects all applicable earlier constraints.

Distractor resistance

KFA Task ID: benchmark-task-scout-d06cf572ee38ce2f06502416

Source or catalog identity: infinitebench-distractor-resistance

Evaluate whether an agent can ignore irrelevant passages while using the necessary long-range evidence in a long context containing controlled distractors. Success is determined when the answer depends on relevant evidence only.

Multi-document synthesis

KFA Task ID: benchmark-task-scout-e9f8203359cbdd5f73893949

Source or catalog identity: infinitebench-multi-document-synthesis

Evaluate whether an agent can combine evidence across several long documents in a closed multi-document context. Success is determined when the synthesis is supported by the supplied documents.
