a2a-agent-card skillA

a2a-agent-card is agent-read markdown (skill) from orcaqubits/agentic-commerce-skills-plugins: Create and configure A2A Agent Cards — the discovery document describing an agent's capabilities, skills, authentication, and endpoint. Use when defining what your agent exposes to other agents..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add orcaqubits/agentic-commerce-skills-plugins/a2a-agent-card@git:20260309.786511c
Exact content
mdr add orcaqubits/agentic-commerce-skills-plugins/a2a-agent-card@sha256:bcccfdaeddc5758f

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
