Cross-cutting ACP development patterns — idempotency, error handling, 3D Secure flows, request signing, rate limiting, monitoring, and security best practices. Use when designing architecture or solving production concerns.

Implement ACP fulfillment options — shipping, digital delivery, in-store pickup, and local delivery. Use when building fulfillment selection, rate calculation, delivery window management, or tracking integration.

Build an A2A client — the agent-side code that discovers other agents, sends tasks, handles responses, and manages multi-turn conversations. Use when implementing the client side that delegates work to A2A agents.

Implement the A2A JSON-RPC 2.0 transport layer — request/response format, method routing, batch requests, and HTTP details. Use when building custom A2A transport handling or debugging protocol-level issues.

Implement A2A multi-turn conversations — input-required state handling, context preservation, iterative refinement, and human-in-the-loop patterns. Use when building agents that need back-and-forth interaction.

Implement A2A task lifecycle management — task creation, state transitions, terminal states, history, and artifacts. Use when building task state machines, handling state transitions, or managing task persistence.

Implement ACP capability negotiation — dynamic discovery of mutually supported capabilities, extensions, payment handlers, and interventions. Use when building multi-feature merchant servers or agents that adapt to merchant capabilities.

Build bridges between A2A and MCP — wrap A2A agents as MCP tools, use MCP tools from A2A agents, and architect hybrid multi-agent systems. Use when integrating A2A agent-to-agent communication with MCP tool access.

Scaffold a new A2A project — install the SDK, create directory structure, configure the Agent Card, and set up a basic server/client. Use when starting a new A2A multi-agent project from scratch.

Implement the ACP discount extension — discount codes, applied discounts, rejected codes, and line-item allocations. Use when adding coupon/promo code support to checkout flows.

Implement the AP2 human-not-present transaction flow — autonomous agent shopping with Intent Mandate authorization, constraint enforcement, and merchant escalation. Use when building autonomous agent purchasing that works after the user has left.

Build an AP2 Credentials Provider — the agent that manages payment credentials, provides payment methods to users, handles tokenization (DPAN), and facilitates secure payment between Shopping Agent and Payment Processor. Use when implementing the Credentials Provider role.
