skillfile

One AI setup, everywhere. Pin it. Patch it. Deploy everywhere.

Use the same skills and agents on your work laptop, personal machine, servers, and whichever AI tools you use. Put the setup in a repo when you want to share it with a team. skillfile locks upstream versions, preserves your edits on update, and installs to Claude Code, Codex, Cursor, Antigravity, custom filesystem paths, and more. No runtime or framework required.

Add a skill once, deploy it to your configured tools, and carry your local edits forward when the upstream skill changes.

Stop manually downloading and copying AI instructions across tools and machines

Without a manager, skills and agents end up as copied markdown files: different versions on every machine, separate copies for every AI tool, and local improvements lost during updates.

Manage them like dependencies:

• Define skills and agents in one Skillfile
• Lock exact upstream revisions in Skillfile.lock
• Deploy the same setup to the AI tools you already use
• Preserve local improvements as patches when upstream content changes
• Fetch skills and agents from GitHub, GitLab, local files, or URLs

Share skills and agents without sharing install targets. Each machine can keep its platform choices in user config; skillfile init can set them. Add install lines when the project should use the same targets.

For individuals

Keep your preferred skills consistent across Claude Code, Codex, Cursor, and other supported tools without manually copying files.

For engineering teams

Commit a Skillfile to a project to share skills and agents. Developers can install them into whichever tools they prefer. If everyone should use the same targets, commit install lines too.

Install

curl -fsSL https://github.com/eljulians/skillfile/releases/latest/download/install.sh | sh

Or:

cargo install skillfile

Prebuilt binaries are published on GitHub Releases.

Quick start

skillfile init
skillfile add github skill anthropics/skills skills/
skillfile install

For GitLab:

skillfile add gitlab skill my-group/my-project skills/
skillfile install

Skillfile.lock pins upstream content to exact SHAs or refs so another machine gets the same files.

Update without losing local edits

Edit an installed file, then pin it:

skillfile pin browser
skillfile install --update

Pinned changes are stored in .skillfile/patches/. If upstream changes conflict, use skillfile diff to review the conflict and skillfile resolve to choose the result.

What it manages

Sources:

• github
• gitlab
• local
• url

Entities:

• skill
• agent

Install targets:

• Built-in AI tool directories with install
• Any filesystem directory with install-path

GitLab project paths may include subgroups. Self-hosted GitLab is supported through GITLAB_HOST.

Example Skillfile

install  claude-code  global
install  codex        global
install-path  openclaw  skill  ~/.openclaw/skills

github  skill  anthropics/skills  skills/slack-gif-creator
gitlab  skill  my-group/platform-skills  skills/release
local   skill  skills/team/reviewer/SKILL.md
url     agent  triager  https://example.com/agents/triager.md

The install-path line sends all three skill entries above to ~/.openclaw/skills in addition to the compatible built-in targets. openclaw is only the target’s display label. See Custom install paths for layouts and a complete example.

Format details live in SPEC.md.

Common commands

skillfile init
skillfile add
skillfile list
skillfile install
skillfile install --update
skillfile status
skillfile diff 
skillfile pin 
skillfile resolve 

Run skillfile add with no arguments for the interactive picker, or use explicit subcommands such as:

skillfile add github skill owner/repo skills/SKILL.md
skillfile add gitlab skill group/project skills/SKILL.md
skillfile add local skill skills/my-skill/SKILL.md
skillfile add url agent https://example.com/agent.md --name my-agent

Auth

GitHub:

• GITHUB_TOKEN
• GH_TOKEN

GitLab:

• GITLAB_TOKEN
• GITLAB_PRIVATE_TOKEN
• GITLAB_HOST for self-hosted instances - a bare hostname such as gitlab.example.com (a https:// prefix or trailing slash is accepted and normalized away)

skillfile init can also save token settings in user config.

Platforms

Supported install targets:

• claude-code
• codex
• cursor
• copilot
• factory
• gemini-cli
• junie
• opencode
• windsurf
• antigravity

Some platforms support skills only; see skillfile init or skillfile --help for the exact target behavior.

Custom install paths

Use install-path when a tool is not built in or reads skills or agents from a nonstandard directory. This creates an install target; it does not add a skill or agent by itself.

For example, this Skillfile declares one custom skill target and two skills:

install-path  openclaw  skill  ~/.openclaw/skills

github  skill  reviewer       acme/skills  reviewer/SKILL.md
local   skill  release-notes  skills/release-notes/SKILL.md

Running skillfile install installs both skill entries into the target:

~/.openclaw/skills/reviewer/SKILL.md
~/.openclaw/skills/release-notes/SKILL.md

In other words, every entry matching the target’s entity type is installed there. If the Skillfile also contained agents, they would not be installed into this skill-only target. Add another target for them:

install-path  openclaw-agents  agent  ~/.openclaw/agents

The label (openclaw or openclaw-agents above) is only a name shown in command output. It does not enable an OpenClaw integration or choose which entries to install. Each target uses these layouts:

Relative paths are resolved from the repository root. ~ and paths beginning with ~/ use your home directory. Custom targets can be mixed with built-in install targets; matching entries are installed to every configured target that supports their entity type.

skillfile validate rejects duplicate destinations for the same entity type. Install and read operations also refuse to traverse user-controlled symlinked path components so a declared target cannot escape through a symlink.

Notes

[!IMPORTANT] skillfile downloads markdown and installs it where your AI tools expect it. It does not sandbox or verify the content.
