Implement A2A error handling — JSON-RPC errors, A2A-specific error codes, task failure states, retry strategies, and graceful degradation. Use when building robust error handling in A2A agents.

Implement A2A messages and parts — TextPart, FilePart, DataPart, message roles, metadata, and content negotiation. Use when building message construction, parsing, or content type handling in A2A agents.

Implement A2A SSE streaming — message/stream method, Server-Sent Events, TaskStatusUpdateEvent, TaskArtifactUpdateEvent, and re-subscription. Use when building real-time streaming responses in A2A agents.

Implement ACP affiliate attribution — privacy-preserving affiliate tracking without cookies using token-based first-touch and last-touch attribution. Use when building affiliate programs, referral tracking, or partnership attribution.

Author custom ACP extensions — composable protocol add-ons with JSONPath targeting, schema composition, and independent versioning. Use when building proprietary or domain-specific extensions beyond the built-in ones.

Implement A2A push notifications — callback URL registration, notification delivery, and management methods. Use when building async notification delivery for long-running A2A tasks.

Test A2A implementations — unit tests, integration tests, mock agents, protocol conformance, and end-to-end multi-agent testing. Use when building test suites for A2A servers, clients, or multi-agent systems.

Implement the ACP REST checkout API — create, update, retrieve, complete, and cancel checkout sessions. Use when building merchant-side checkout endpoints, handling the checkout session state machine, or integrating with AI agent checkout flows.

Validate an ACP implementation against the protocol specification — schema validation, flow testing, error handling, idempotency, security checks, and production readiness. Use when preparing for launch or certifying compliance.

Implement the ACP delegated payment flow and SharedPaymentToken (SPT) provisioning. Use when integrating with Stripe for payment tokenization, handling SPT lifecycle, or building the payment completion flow.

Implement ACP intent traces — structured cart abandonment signals with reason codes for analytics and automated recovery workflows. Use when building abandonment tracking, recovery automation, or conversion optimization.

Create and configure A2A Agent Cards — the discovery document describing an agent's capabilities, skills, authentication, and endpoint. Use when defining what your agent exposes to other agents.
