The Krun agent skill teaches coding agents how to build with Krun: when a decision model fits and when it doesn’t, which primitive to use (choice, noul, score, multi), how to act on probabilities and abstention, how to batch questions for latency, and how to send images, documents and audio through assets. For version-dependent details, such as limits and SDK signatures, the skill sends the agent to these docs. The skill is instructions only. It doesn’t run code, call the Krun API or read your API key.

​
Installation

Add the Krun marketplace and install the plugin:
Claude loads the skill when a task involves Krun. You can also invoke it directly with /krun:krun.

​
Use it

Describe the outcome you want and mention Krun:
The agent needs an API key only to run the code it writes. Set KRUN_API_KEY in your server environment. See Authentication.

​
Update

​
Combine with the docs MCP server

The skill covers design; the docs MCP server lets the agent search these docs while it works. You can use both. See Use these docs with AI agents.
