Agents & MCPSkill
A behind-the-scenes rulebook that tells the AI how to write better instructions when it hands a coding or debugging task off to another AI model, so you get more reliable results from that handoff.
Your agent shows you the skill and checks it before adding it. Text instructions only.
Checked by Orbit: nothing risky found in what it runs or reads.
