Source code
Specification source, JSON schemas, 13 reference implementations, conformance test suite, and CLI tools.
What AAEP enables
Today, AI agents and assistive technology cannot talk to each other in a standardized way. A blind user running an AI coding assistant has no reliable way for their screen reader to announce what the agent is doing, when it needs confirmation, or whether a tool invocation succeeded.
AAEP defines a vendor-neutral protocol for AI agents to emit structured events about their lifecycle, reasoning, tool use, and human-in-the-loop interactions. Assistive technology subscribes to these events and presents them to users in their preferred modality and language.
The protocol is transport-agnostic, supports first-class multilingual operation (including Yoruba, Hausa, and Igbo at v1.0.0), and ships with three conformance levels so vendors can certify their implementations.
