Feature Request: Add Google Antigravity Support to Project CodeGuard - #71

[Parveen-Birthaliya]

Summary

Add native support for Google Antigravity workflows, enabling CodeGuard security rules to be triggered on-demand in the Antigravity IDE using /codeguard-* commands.

• Followed Same structure as other IDEs
• Maintain consistency with existing IDE integrations

Architecture

Following the established BaseFormat pattern used by Cursor, Windsurf, and other IDE integrations:

class AntigravityFormat(BaseFormat):
    - Output directory: `.agent/rules/`
    - File extension: `.md`
    - Frontmatter: description + tags (minimal, per Antigravity spec)

Files to Create

1. src/formats/antigravity.py - AntigravityFormat class

Files to Modify

1. src/formats/__init__.py - Register AntigravityFormat
2. src/convert_to_ide_formats.py - Add to conversion pipeline
3. README.md - Update supported IDEs list
4. docs/getting-started.md - Updated supported IDEs list ,Add documentation link

Test

• Unit tests for AntigravityFormat class
• Integration tests for rule conversion
• Manual validation in Antigravity IDE

Below is the Secreen shot from atigravity IDE that shows proper working of rules :

Thanks for adding Antigravity support! The implementation looks good but needs a few fixes:

Main Issue - Missing Frontmatter: The antigravity.py implementation doesn't generate the required trigger and globs fields needed for proper activation. Currently it only outputs description and tags (tags aren't needed: they're just for CLI filtering, not rule output).

What's needed: Like Windsurf's implementation, it should generate:

• trigger: always_on (for rules with always_apply: true)
• trigger: glob + globs: [patterns] (for language-specific rules)
• version field (for consistency)

Also: The PR description mentions /codeguard-* commands, but those are for Workflows, not Rules. Rules use activation types instead: Always On and Glob are the important ones for CodeGuard.

Quick Fixes:

• Update generate() method to add trigger, globs, and version fields (see windsurf.py for reference)
• Remove tags from output (not needed in rule files)
• Update comments to explain Rules activation (not slash commands)
• Fix doc link to https://antigravity.google/docs/rules-workflows
• Standardize: "Antigravity" + add space: "Claude Code, Antigravity)"

Happy to help if you have questions!

@thomas-bartlett can you check now , if there is more need to change in the features code

Thanks for the updates! The implementation is working correctly.

A few items to address:

Text fixes:

• README.md line 57: Claude Code,antigravity → Claude Code, Antigravity (add space, capitalize)
• docs/getting-started.md lines 34, 35, 37: AntiGravity → Antigravity (lowercase 'g')

Other:

• Please resolve the Copilot review comments

The CI workflow updates (validate + release zips) can be done in a follow-up PR.
