Add native Antigravity CLI plugin packaging

[nehal-a2z]

What changed

• Add the repository-root plugin.json manifest required by Antigravity CLI.
• Document direct installation with agy plugin install https://github.com/coderabbitai/skills and verification with agy plugin list.
• Correct Antigravity's workspace and global skill paths, and record the native distribution channel in the changelog and maintainer inventory.

Before → After

Before: the repository was available through generic skill installers but had no native Antigravity plugin manifest, and its Antigravity paths were stale.

After: Antigravity CLI can install the repository as a native plugin and discover its two skills, code-review subagent, and review command.

Validation

• Antigravity CLI 1.1.4: agy plugin validate .
  • 2 skills processed
  • 1 agent processed
  • 1 command processed and converted to a skill
• git diff --check

Related

• DX-937
• Runtime detection: coderabbitai/mono#19563

Summary by CodeRabbit

• New Features

  • Documented the plugin’s included skills, review command, and code-review subagent.

• Documentation

  • Updated supported installation paths, plugin components, resources, and distribution-channel records.
  • Added maintenance guidance for validating the plugin manifest when packaging requirements change.

79-90: 🎯 Functional Correctness

Verify the commands/ conversion contract before merge.

The official plugin documentation lists skills, agents, rules, hooks, and MCP as native components, and says skills become slash commands; it does not document a commands/ directory or automatic commands/... → skill conversion. Confirm that Antigravity CLI 1.1.4 actually performs this conversion and that agy plugin validate . passes; otherwise, move the review command into a supported skills/ location and update these descriptions. (antigravity.google)

Also applies to: 106-109, 240-245

---

143-143: 🎯 Functional Correctness

Reconcile the global Antigravity skills path.

Official Antigravity pages currently document different paths: ~/.gemini/config/skills/ and ~/.gemini/antigravity-cli/skills/. Verify which path Antigravity CLI 1.1.4 actually scans and document the version-specific path or both supported locations. (antigravity.google)

📝 Walkthrough

Walkthrough

The documentation now describes native Antigravity CLI plugin packaging through the root plugin.json manifest. README instructions cover installation, listing, component conversion, supported paths, and documentation links. Distribution records add the Antigravity plugin channel, update verification metadata, and require agy plugin validate . after manifest or schema changes. The changelog records the new packaging support.

Poem

I’m a rabbit with plugins tucked neat,
Hopping through manifests crisp and complete.
agy plugin install, then list what you’ve grown,
Skills and commands now travel well-known.
A carrot for docs, validation too—
Antigravity hops right through!
