Stable Task identities and signatures

Tool selection

KFA Task ID: benchmark-task-scout-0d9969d9eecd01e85e4d4a25

Source or catalog identity: api-bank-tool-selection

Evaluate whether an agent can select the applicable tool and construct schema-valid arguments in a declared tool registry. Success is determined when the intended tool is called with valid arguments.

Tool abstention

KFA Task ID: benchmark-task-scout-345caa9fc9514269cd57e3df

Source or catalog identity: api-bank-tool-abstention

Evaluate whether an agent can decline to call a tool when none is applicable or authorized in a restricted tool environment. Success is determined when the agent avoids an invalid or unauthorized action.

Parallel tool judgment

KFA Task ID: benchmark-task-scout-b2a7570c319555b15312acec

Source or catalog identity: api-bank-parallel-tool-judgment

Evaluate whether an agent can identify independent tool calls that can be issued together in a bounded tool catalog. Success is determined when all necessary calls are valid and no unsupported call is invented.

Multi-step tool use

KFA Task ID: benchmark-task-scout-e94251e4122cb727cafb0569

Source or catalog identity: api-bank-multi-step-tool-use

Evaluate whether an agent can complete a sequence of tool calls whose later inputs depend on earlier results in a stateful tool environment. Success is determined when the final declared state is reached.
