Specialized skill for creating new Antigravity agent skills. Follows a Research -> Create -> Deploy workflow where the Agent directly creates the necessary files.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Create New Skill

This skill guides the agent in creating a new Antigravity skill. It uses an Agent-Native workflow where the Agent directly researches the topic and creates the files, rather than relying on external scripts.

When to use this skill

  • The user explicitly asks to "create a skill", "make a new skill", or "add a skill".
  • The user asks how to create a skill and wants you to do it for them.

How to use it

Creating a New Skill

  1. Gather Information:

    • Ask for the Skill Name (must be lowercase with hyphens, e.g., code-review, postgres-helper).
    • Ask for the Scope (Local Repo vs Global). Default is Local Repo.

  2. Research Phase:

    • Search: Perform a web search (search_web) using the skill topic to find:
      • Official documentation and key concepts.
      • Primary libraries, tools, or APIs involved.
      • Standard patterns, best practices, or existing solutions.
    • Synthesize: Note down key URLs and concepts to include in the skill's reference documentation.

  3. Create Skill Files:

    • Method: Use your write_to_file tool to directly create the necessary files.
    • Location: <workspace-root>/.agent/skills/<skill-name>/

    a. Create SKILL.md: - Format: Must start with YAML frontmatter followed by Markdown. - Frontmatter Rules (Strict Compliance): - name: Required. Must match directory name. Lowercase a-z, 0-9, - only. Max 64 chars. No consecutive hyphens. - description: Required. Max 1024 chars. Describe what it does and when to use it. - license: Optional (Recommended). e.g., Apache-2.0 or MIT. - metadata: Optional. Key-value pairs for versioning/authorship. yaml --- name: <skill-name> description: <summary from research> license: MIT metadata: author: agent version: "1.0" --- - Content Rules: - Keep simple (< 500 lines). - Use references/ for long documentation (Progressive Disclosure). - Include "Overview", "Methodology", "When to use", and "Examples".

    b. Create references/research.md: - Create the references/ directory. - Write the research notes, key concepts, and URLs found during the research phase.

  4. Finalize:

    • No Scripts Needed: You do NOT need to run any python scripts.
    • Notify: Inform the user the skill has been created in the repository.

Validating a Skill

  1. Manual Specification Check:

    • Action: Verify the skill against the Agent Skills Specification.
    • Checklist:
      • name: lowercase, hyphens only, matches directory name, 1-64 chars.
      • description: 1-1024 chars, describes "what" AND "when to use".
      • license: Present (optional but recommended).
    • Fix Loop: If any field is invalid, FIX the file and RE-VERIFY.

  2. Manual Reality Check:

    • Read Back: view_file the SKILL.md.
    • Does the description accurately reflect the content?
    • Is the license: MIT present?

Packaging a Skill

Not required for local development.

Rules

  • Safe Creation: Check if the skill directory (.agent/skills/<name>) exists before creating. If it exists, STOP and ask the user if they want to overwrite.
  • Do NOT use uv, ruff, or python scripts. This is an agent-native skill.
  • Do NOT create files in ~/.gemini/antigravity/skills directly. Always work in the repository.
  • Ensure the name in the frontmatter matches the folder name (lowercase, hyphens).
