Agent Skills

Agent skills are installable SKILL.md guides (plus optional references) for coding agents in Cursor, Claude Code, and similar clients. Cartesia’s official pack is cartesia-ai/skills, and Claude Code can install the same pack as the cartesia-skills plugin. Not using skills? Paste this prompt into your editor rules instead:
