Agreement Overview

Definition

An ASA Agreement is a standardized, executable contract defined by agent service providers for a specific business interaction slice.

Design Principles

• Minimal disclosure
• On-demand loading
• Deterministic interaction semantics
• Reusable abstraction for same-type operations across providers

Why Agreement Matters

When multiple providers expose the same business type under one agreement family, demand-side agents can keep cleaner context and avoid duplicated skill scripts. This improves execution determinism and reduces token overhead.

Lifecycle

1. Draft agreement
2. Validate and pre-post check
3. Publish via repository/process
4. Service providers implement endpoints
5. Agents consume and cache contract metadata
6. Evolve by version

Typical Composition

Different agreements can be composed in business flows, for example:

• shopping agreement
• payment agreement

The agent can load only needed agreements for current step.
