Ready-to-use skills for Builder.io that extend what the AI can do in your projects.

Skills are folders containing a SKILL.md file that teach the AI new capabilities — workflows, conventions, knowledge, and tools specific to your project. They live at .builder/skills/ in your project directory.

You can install skills by asking Builder to run npx builder-doctor which will give you an option to install a skill. You can also quickly add a specific skill by asking:

• npx builder-doctor install-skill skill-creator
• npx builder-doctor install-skill fusion-to-publish
• npx builder-doctor install-skill rules-reviewer
• npx builder-doctor install-skill import-prototype

Create new skills, improve existing skills, and understand skill best practices for Builder.io

Ask Builder to run npx builder-doctor install-skill skill-creator and it will be installed in your project. Or you can run locally with:

npx builder-doctor install-skill skill-creator

1. Install the skill-creator skill into your Builder.io project (see Installation above)
2. Open your project in Builder and say "I want to create a skill that does X"
3. The skill-creator will guide you through the process

Review, fix, and create Builder.io Fusion rules files (.builderrules, .mdc, agents.md).

Ask Builder to run npx builder-doctor install-skill rules-reviewer and it will be installed in your project. Or you can run locally with:

npx builder-doctor install-skill rules-reviewer

Ask Builder to Review my rules after installing this skill. You can also ask run npx builder-doctor rules which will check for common issues with rule files.

Import a Builder.io prototype into the current project using the Builder dev-tools CLI.

Ask Builder to run npx builder-doctor install-skill import-prototype and it will be installed in your project.

Or you can run locally into GitHub CoPilot with:

run npx --yes builder-doctor install-skill import-prototype --agent github

Or you can run locally into Claude Code with:

run npx --yes builder-doctor install-skill import-prototype --agent claude

Share a https://builder.io/app/projects/... URL with Builder and say what you want to import (e.g. "import the hero section" or "import the full page design"). The skill will run the Builder dev-tools CLI to pull the prototype into your project.

Copy any skill directory into your project's .builder/skills/ folder:

# Clone the repo
git clone https://github.com/BuilderIO/builder-agent-skills.git /tmp/builder-agent-skills

# Copy the skill you want (example: skill-creator)
mkdir -p .builder/skills
cp -r /tmp/builder-agent-skills/skill-creator .builder/skills/skill-creator

# Clean up
rm -rf /tmp/builder-agent-skills

Or copy a single skill directly:

mkdir -p .builder/skills/skill-creator
curl -sL https://raw.githubusercontent.com/BuilderIO/builder-agent-skills/main/skill-creator/SKILL.md \
  -o .builder/skills/skill-creator/SKILL.md

After installing, start a new session for the skill to load.

1. Create a directory with your skill name (lowercase, hyphenated)
2. Add a SKILL.md with valid frontmatter (name and description)
3. Follow the skill writing best practices
4. Keep SKILL.md under 500 lines; use references/ for detailed docs
