SkillCreator is a macOS desktop app for creating agent skills, structured Markdown instruction files that teach AI coding agents how to perform specific tasks. Skills work across Claude Code, GitHub Copilot, Cursor, Codex, Gemini CLI, and more.

Quickstart

Build your first skill in under 5 minutes.

Installation

Download the desktop app for macOS.

What are skills?

Understand the skill format and how agents use them.

​
Why SkillCreator?

Most AI coding agents accept plain-text instructions, but there is no standard way to create, version, test, or share those instructions. SkillCreator gives you a dedicated workspace:
  • Studio. Generate skills from prompts, URLs, docs, or images using AI.
  • Editor. Full IDE with Monaco, file tree, frontmatter editing, and validation.
  • Library. SQLite-backed local index of all your skills with search, tags, and versioning.
  • Evals. Score skills on 6 quality dimensions and track regressions over time.
  • Graph. Visualize skill dependencies on an interactive canvas.
  • Terminal. Embedded PTY for running agents directly inside the app.

​
How it works

1

Capture

Paste a URL, drop files, or describe what you want the agent to do. The Studio ingests your sources and extracts structure.
2

Generate

AI synthesizes a structured SKILL.md with metadata, instructions, constraints, and verification steps.
3

Evaluate

Run quality evals that score structure, content, evidence, usage, toolchain, and freshness.
4

Install

Export to any agent runtime (Claude Code, Cursor, Copilot, Codex, Amp, and more) with a transactional install that previews diffs and supports rollback.

​
Architecture

SkillCreator stores all data locally in a SQLite database. Skill generation requires an API connection; the app itself stores all data locally and does not send skill content to any server. An optional MCP server exposes your skill library to AI agents for live introspection.
