Designs and optimizes AI agent action spaces, tool definitions, observation formats, error recovery, and context for higher task completion rates.
Enables AI agents to execute x402 payments with per-task budgets, spending controls, and non-custodial wallets via MCP tools. Use when agents pay for APIs, services, or other agents.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.

Delivery reports are sent via Azure Event Grid. Configure an Event Grid subscription for your ACS resource.
// Event Grid webhook handler (in your endpoint)
public void handleDeliveryReport(String eventJson) {
// Parse Event Grid event
// Event type: Microsoft.Communication.SMSDeliveryReportReceived
// Event data contains:
// - messageId: correlates to SmsSendResult.getMessageId()
// - from: sender number
// - to: recipient number
// - deliveryStatus: "Delivered", "Failed", etc.
// - deliveryStatusDetails: detailed status
// - receivedTimestamp: when status was received
// - tag: your custom tag from SmsSendOptions
