Build with AI
Skills
Package reusable instructions as skills. Lyna loads a skill when your request matches it, or you call it by name.
A skill is a set of instructions for one kind of task, such as adding a checkout or writing SEO copy. Unlike a rule, a skill stays out of the way until a request matches it.
What you can do
- Use Lyna's built-in and curated skills.
- Write a skill by hand, build one with the AI, import one from GitHub or a file.
- Share skills with your whole workspace through the Skills library.
- Choose which skills each project uses.
- Call a skill by name with
/skill-name.
How skills work
- Write or import a skill.
- Lyna picks it up: when a request matches the skill's description, Lyna loads it on its own.
- Call it by name: type
/skill-namein the chat to use it right away.
Where skills come from

Pick a method
- Write manually: write the SKILL.md yourself.
- Build with AI: describe it and let the assistant draft it.
- From GitHub: pull a SKILL.md from a public repository. You can also add it to the workspace library.
- Import from file: a
.md,.mdx,.zipor.skillfile.
Fill in the skill
- Skill Name: lowercase letters, numbers and hyphens. It becomes the permanent id.
- Description: start with "Use when" and name the trigger, the scope and the limit, so Lyna recalls it at the right time.
- Instructions: step-by-step instructions for the assistant.
- Use automatically: when on, Lyna uses the skill when your message matches its description. When off, the skill is Manual only.
Use trusted sources only
Skills from unknown sources may contain unsafe or harmful instructions. Read a skill before you add it.
The SKILL.md format
Each skill is a folder under .lyna_ai/skills/ with a SKILL.md file and optional extra files.
