Claude Skill Importer

This skill provides utilities to import skills defined for "Claude Code" (e.g., from any-forward/skills or loose .md files) and convert them into the structured format required by Antigravity Agents.

Capabilities

1. Import: Copies skills from a source directory.
2. Normalize:
   • Ensures valid YAML Frontmatter (name, description) exists.
   • Converts flat .md files into valid Skill Directories (folder/SKILL.md).
3. Completeness:
   • Generates metadata.json automatically.
   • Generates SKILL.ja.md (Japanse placeholder) automatically to satisfy strict format requirements.

Usage

You can invoke this skill by running the bundled script via run_command.

Command Syntax

node .gemini/antigravity/skills/ai-tools/claude-skill-importer/scripts/importer.js <SOURCE_DIRECTORY> [TARGET_CATEGORY_NAME]

• SOURCE_DIRECTORY: The absolute path to the folder containing Claude skills. This can be:
  • A flat folder of .md files.
  • A standard plugins/ structure (Trail of Bits style).
• TARGET_CATEGORY_NAME (Optional): The name of the subdirectory within .gemini/antigravity/skills/ where these will be placed. Defaults to imported-skills.

Example

# Import skills from a flat folder into "my-new-skills"
node .gemini/antigravity/skills/ai-tools/claude-skill-importer/scripts/importer.js /Users/me/downloads/claude-skills my-new-skills

Supported Source Formats

• Flat Markdown: folder/my-skill.md -> skills/imported/my-skill/SKILL.md
• Plugin Structure: folder/plugins/my-plugin/skills/my-skill/SKILL.md -> skills/imported/my-skill/SKILL.md

Localization Process (Post-Import)

The importer script generates SKILL.ja.md as a placeholder. You MUST complete the translation process manually or by instructing the agent.

1. Verify: Check the generated SKILL.ja.md. It will contain a > Note: This is a placeholder block.
2. Translate:
   • Read the content of the English SKILL.md.
   • Translate the Title, Description, and Body content into Japanese.
   • Important: Keep the YAML Frontmatter keys (like name, description) in English format, but translate their values if appropriate (or append (JP)). Ensure language: ja is present.
3. Overwrite: Replace the placeholder content in SKILL.ja.md with the full Japanese translation.
