One source, every tool.
Install the same skill or agent into Claude Code, Codex, Cursor, Copilot, Gemini, Junie, opencode, or any folder-based destination. No copies, no drift.
Build reusable AI workflows from files you own.
Skillful turns prompts, agents, screenshots, scripts, and notes into a filesystem library you can inspect and maintain. Edit folders directly, preview markdown, import public skill repos, and install the same item into every AI tool that needs it.
- Free
- Works offline
- Filesystem-first
- Source-available FSL license
Everything in one place.
Prompts, screenshots, scripts, and supporting notes live next to the skill that uses them.
Skills and agents together.
Keep SKILL.md and AGENT.md workflows in one library, with
filters and badges that make the difference clear without splitting your workspace.
Break-proof installs.
Spot broken symlinks, repair them in a click, and remove cleanly when a skill has outlived its use.
Share libraries over git.
Point Skillful at a git repository and it keeps that library in sync next to your own. Pull-only, two-way, or read-only for a team playbook nobody edits by accident.
Tune every tool.
Edit CLAUDE.md, AGENTS.md, and GEMINI.md in
place, right where each tool reads them, and back them up with your library.
Before & after
Built for workflows that change as you work.
Before Skillful
-
Your agents live inside one tool. Your prompts are scattered across
~/notes/,~/dotfiles/, and four Obsidian vaults. - Codex has its own copy of half of them.
- Two of those copies are out of date. You don't remember which.
- Screenshots and helper scripts are three folders away from the prompt that uses them.
After Skillful
- One library. Every skill or agent is a readable folder plus whatever it needs.
- You link each item into the tools that should see it.
- Tweak the source in Skillful, and linked installs automatically update.
- Broken links surface in the sidebar and repair in a click.
Your library, your disk.
Skillful is source-available and free. Your skills, agents, and notes stay on your machine, or in a git repository you choose: no account, no telemetry, no servers. You own the folder, and if Skillful ever disappears your library still works, because it's all local.
FAQ
Questions people ask before downloading.
Is it really free?
Yes. The source is available under the Functional Source License 1.1 with an MIT future license. Personal, internal, education, research, and professional-services use are allowed; competing commercial products or services are not.
Do my skills ever leave my machine?
Only if you ask. Everything stays on your local filesystem and Skillful has no backend and no analytics. Update checks and GitHub imports talk to GitHub, and git backup and git libraries talk to the git remotes you configure yourself. See the Privacy section for the full list.
Which tools does it install into?
Skillful ships one-click installers for Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Junie, and opencode. You can also add your own custom install targets: point Skillful at any folder on disk and it'll treat it like the built-in ones. As many as you like, per skill or per collection.
Which downloads are available?
Skillful publishes Windows, macOS, and Linux builds on GitHub Releases. Linux releases include AppImage, deb, rpm, pacman, Snap, and Flatpak artifacts so you can pick the install style that matches your system.
Can Github repositories link straight into Skillful imports?
Yes. Skillful supports direct import links, so a repository README can open the app with a GitHub repository already filled into the import dialog. That makes public skill libraries much easier to try without copying URLs around by hand.

How do I back up my library?
Turn on git backup in settings and point it at a private repository. Skillful commits your settings, your library, and optionally your tools' instruction files, pushes them on an interval if you like, and restores everything on a new machine.
Your library is still just a folder, so your usual backup tool works too. There's nothing proprietary to export and nothing to migrate when you switch machines.
Can I edit CLAUDE.md and AGENTS.md too?
Yes. Select a tool in the sidebar and open its instructions: Skillful edits the
tool's own file in place, such as ~/.claude/CLAUDE.md or
~/.codex/AGENTS.md, plus Claude Code's rule files. If the tool changed
the file while you were editing, Skillful asks before overwriting it.
Privacy
What leaves your machine.
Skillful is local-first. There is no Skillful account, no Skillful server, and no analytics or telemetry of any kind. The app makes a small, predictable set of outbound network requests, only when you ask for them or to keep the app up to date:
-
Update checks. The desktop app checks
github.com/Mastermindzh/skillful/releasesfor new versions when you open the Updates tab or on launch. No identifying information is sent beyond what GitHub already logs for any HTTPS request. -
GitHub imports. When you import a public repository, Skillful
downloads the repository's source archive directly from
codeload.github.com. Nothing is uploaded. -
Deep links. Opening a
skillful://import?...link only prefills the import dialog locally. No request is made until you click Import. - Git backup (opt-in). When you turn it on, Skillful pushes your settings, library, and (if you choose) your tools' instruction files to the git remote you configured, and pulls them back when you restore.
- Git libraries (opt-in). Each git library you add is cloned and synced from its remote; two-way libraries also push your changes back to it.
That's the entire list. Git operations use your system git and ssh keys; Skillful never reads or stores credentials. Beyond the remotes you set up yourself, your skill folders, drafts, settings, and library paths never leave your disk. You can verify this by reading the source or by watching network traffic with your tool of choice.
