a2a-client SKILL.md skillA
a2a-client from orcaqubits/agentic-commerce-skills-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build an A2A client — the agent-side code that discovers other agents, sends tasks, handles responses, and manages multi-turn conversations. Use when implementing the client side that delegates work to A2A agents.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# A2A Client Implementation ## Before writing code **Fetch live docs**: 1. Fetch `https://a2a-protocol.org/latest/specification/` for client-side protocol requirements 2. Web-search `site:github.com a2aproject a2a-python client` or `a2aproject a2a-js client` for SDK client classes 3. Web-search `site:github.com a2aproject a2a-samples client` for reference client implementations 4. Fetch the target SDK README for client usage patterns ## Conceptual Architecture ### What an A2A Client Does An A2A client is the **requesting side** that: 1. Discovers agents via Agent Cards (fetch `/.well-known/agent-card.json`) 2. Sends messages to create or continue tasks 3. Handles synchronous responses or SSE streams 4. Manages multi-turn conversations (handles `input-required` states) 5. Optionally configures push notifications for long-running tasks ### Client Workflow ``` 1. Discover agent → Fetch Agent Card 2. Check capabilities → Verify the agent can handle the task 3. Authenticate → Satisfy the agent's auth requirements 4. Send message → POST JSON-RPC to agent URL 5. Handle response → Process task result or continue conversation 6. Monitor → Poll, stream, or receive push notifications …

How to install
mdr add orcaqubits/agentic-commerce-skills-plugins/a2a-client@sha256:d88772fef5a9fd69The line at the top of this page pins the label git:20260309.786511c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
