Methodology

Cross-Functional 40 · August 2026

Scenario design

Each task starts from an exact, resettable seed containing the business records, policies, and provider tools a capable human would need. The seed supplies context, not procedural breadcrumbs: agents choose which tools to call and in what order.

Prompts and autonomy

Prompts describe the situation, the operator's role, and the safety boundary in human terms. They do not enumerate expected API operations or disclose the hidden verification path. The exact prompt used for every task is published above.

Grading

Deterministic graders require every critical business outcome and reject critical forbidden side effects. Correct provider state passes regardless of call order, retries, or response phrasing. Documentation lookups are recorded separately from business API calls.

Run protocol

The 40 scenarios ran with concurrency 10. Each received one Fable 5 High invocation and one clean teardown. Because this publication reports one trial per task, it is an observed suite result—not a confidence interval or a claim about repeat-level variance.

Make your agents more capablein the real world.

Spin up isolated environments with API twins, full traces, and production-data for apps and agents that need to act.
