## What a2acli does, in the publisher's words

A standalone, A2A Specification v1.0 compliant command-line client for discovering, messaging, and managing agents. Built on the a2a-go SDK with an interactive streaming TUI and a scriptable JSON mode.

A2A (Agent-to-Agent) is an open protocol for talking to AI agents over a network, discover what an agent can do, send it a message, and stream back results and artifacts, regardless of how the agent is built. Every agent publishes an AgentCard (its skills, security requirements, and transports); you send a message that creates a task; the task moves through states (working → completed) and may produce artifacts (text, data, files).

a2acli is the command-line client for that protocol. To learn the protocol itself, see the canonical site: a2a-protocol.org.

## Skills

- a2a-conformance: Evaluate an existing Agent-to-Agent (A2A) protocol service or agent for specification compliance, security best practices, and quality design. Uses static inspection, a2acli probes, and official TCK orchestration to produce a structured conformance report with stable check IDs. Use when asked to au…
- a2a-expose: Guide developers and coding agents in adding an A2A Protocol v1.0 exposure layer to an existing API, microservice, or codebase. Enforces a design-first workflow (intent-based skill modeling, task lifecycle, artifact delivery, and security mapping) before emitting Go or Python SDK code, followed by…
- a2acli: Interact with Agent-to-Agent (A2A) protocol services from the command line. Use when you need to discover agent capabilities, send tasks, poll status, stream results, manage tasks, or authenticate with OAuth 2.1-protected A2A agents.
