It provides schema management (loading and validating A2UI message schemas), incremental parsing with automatic JSON repair, and integration with Google's Agent Development Kit (ADK) to send UI to clients via tool calls. The package includes a basic catalog of standard A2UI components and utilities for managing A2A (Agent-to-Agent) protocol extensions.\n\nThe SDK is designed for developers building multi-agent systems where agents need to render user interfaces or exchange structured information. It handles the low-level protocol details\u2014schema validation, payload repair, and streaming parsing\u2014so you can focus on agent logic. The package explicitly warns that external agent data and UI definitions must be treated as untrusted input and properly sanitized to prevent prompt injection, XSS, and spoofing attacks.","worth_installing":"Yes, if you are building agents that need to exchange UI or structured data via the A2UI/A2A protocols and are willing to verify the license status. The package is actively maintained, has low install friction, and provides essential protocol handling. However, do not install without clarifying the license terms and understanding the security warnings about untrusted agent data\u2014this is not a general-purpose UI library."},"id":"a2ui-agent-sdk","links":{"html":"https://skillfed.io/packages/a2ui-agent-sdk","md":"https://skillfed.io/packages/a2ui-agent-sdk.md","pypi":"https://pypi.org/project/a2ui-agent-sdk/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-31","license_spdx":null,"license_treatment":"unclear","name":"a2ui-agent-sdk","python_support":"supports_current","summary":"A2UI Agent SDK"},"popularity":{"monthly_downloads":184314,"position":10042,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.5.0"}
