Agent skills

Cosmos-Framework ships skills for coding agents such as Claude Code and Codex: step-by-step instructions to install, run, post-train and troubleshoot Cosmos3 models, and to work on this repository. Each skill is a folder with a SKILL.md file; see Agent Skills.

Load the skills

The skills refer to files in the repository, so work in a clone:

git clone https://github.com/NVIDIA/cosmos-framework.git
cd cosmos-framework
  • Codex loads the skills in .agents/skills/ when you start it in the clone.
  • Claude Code loads only the skills in .claude/skills/, a subset of the table below. To load them while working in another project, start it with claude --add-dir <path to the clone>.
  • For any skill your agent does not load, ask it to read the skill's SKILL.md.

Agents reading this site can start from llms.txt. It links the Markdown of every page and every skill below.
