It provides no framework dependencies itself\u2014instead, it exports constants, operation builders (like create_surface and update_components), prompt composition helpers, state walkers, and orchestration functions that framework-specific adapters (for LangGraph, ADK, Mastra, and others) can wrap with their own decorators and runtime bindings.\n\nThe package is designed to be composed into framework adapters rather than used directly in application code. It handles the semantic and structural work of building A2UI requests, envelopes, and prompts, leaving framework integration to the adapter layer. With no runtime dependencies and active maintenance, it serves as a shared foundation for multiple agent frameworks to build A2UI tooling on top of.","worth_installing":"Yes, if you are building a framework adapter for A2UI subagent tools or integrating A2UI operations into an agent system. No, if you are looking for a direct end-user agent framework\u2014this is a foundation library meant to be composed into adapters. Install it as a dependency of your framework adapter, not as a standalone tool."},"id":"ag-ui-a2ui-toolkit","links":{"html":"https://skillfed.io/packages/ag-ui-a2ui-toolkit","md":"https://skillfed.io/packages/ag-ui-a2ui-toolkit.md","pypi":"https://pypi.org/project/ag-ui-a2ui-toolkit/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-17","license_spdx":"MIT","license_treatment":"permissive","name":"ag-ui-a2ui-toolkit","python_support":"supports_current","summary":"Framework-agnostic helpers for building A2UI subagent tools \u2014 op builders, prompt assembly, history walkers, and request/envelope orchestration shared across framework adapters."},"popularity":{"monthly_downloads":667073,"position":5422,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.0.4"}
