Agents (cross-client default)

The cross-client interoperable default. Any AI agent product that reads from the .agents/ tree can consume skills and agents deployed under this client. Pick this one when you do not know (or do not care) which specific product will consume the artifact, or when you want to share a single skill or agent across multiple products. The default agent format is markdown-with-frontmatter because it is the format both Claude Code and Gemini CLI use and is the most widely supported by tooling.
