AI Skill Builder
Create SKILL.md files for Claude Code, Cursor, GitHub Copilot, and other AI coding tools. Everything runs in your browser — nothing is sent to any server.
Metadata
Allow users to invoke this skill via slash command (e.g. /my-skill)
Tells the AI when this skill should be activated
Skill body
The main instructions and guidelines. Supports full markdown.
Additional sections
Break your skill into logical sections. Each gets its own ## Heading.
Save this file as SKILL.md inside a directory in your repo. SkillInvoke auto-discovers skills by scanning for directories containing a SKILL.md file.
Directory structure: category/skill-name/SKILL.md
How SKILL.md files work
Skills are markdown files with YAML frontmatter that tell AI coding assistants how to behave. They work with Claude Code, Cursor, GitHub Copilot, and other tools.
Write in markdown
Skills are plain markdown files. YAML frontmatter holds metadata like name, category, and tags. The body contains your instructions.
Store in your repo
Drop the SKILL.md file into a directory in your GitHub repository. Organise by category with nested folders or keep it flat.
Sync to every machine
Use the SkillInvoke CLI to sync skills to your team's machines. One command pulls every skill to the right directory.
Frontmatter reference
| Field | Type | Required | Description |
|---|---|---|---|
| name | string | Yes | Display name for the skill |
| description | string | No | Short description shown in listings |
| category | string | No | Grouping category (e.g. Frontend, Backend) |
| tags | string[] | No | Searchable tags for discovery |
| user_invocable | boolean | No | Allow invocation via slash command |
Manage skills across your team
SkillInvoke lets you bundle skills into packs, sync them via CLI, and govern what AI tools your team uses.
