We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Every skill must have a root SKILL.md with standard YAML frontmatter with name and description.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Antigravity Customization System

This skill explains how customizations work within Antigravity (AGY), their discovery mechanisms, loading priorities, and best practices for creating skills, rules, plugins, and MCP servers.

When to Use

  • Writing new custom skills for Antigravity workspaces.
  • Adding repository rules (.agent/rules/*.md or AGENTS.md).
  • Configuring Model Context Protocol (MCP) servers (~/.gemini/antigravity-cli/mcp/).
  • Building lifecycle hooks and terminal integration extensions.

Discovery & Loading Priority

Customizations are discovered and merged in the following order of precedence (highest to lowest):

  1. Workspace Local: <workspace_root>/.agent/skills/
  2. Global User: ~/.gemini/antigravity-cli/skills/
  3. Built-in System: antigravity-cli/builtin/skills/

Authoring Canonical SKILL.md

Every skill must have a root SKILL.md with standard YAML frontmatter with name and description.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
