Feature Request: Add Google Antigravity Support to Project CodeGuard - #71 #74

Parveen-Birthaliya · 2025-11-29T05:24:23Z

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

src/formats/antigravity.py - AntigravityFormat class

Files to Modify

src/formats/__init__.py - Register AntigravityFormat
src/convert_to_ide_formats.py - Add to conversion pipeline
README.md - Update supported IDEs list
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 :

+    Workflows are stored in .agent/workflows/ and can be triggered
+    on-demand with /workflow-name in the Antigravity interface.


The documentation comments refer to "workflows" but the code uses "rules". According to the get_output_subpath() method (line 35), files are stored in .agent/rules/, not .agent/workflows/. The comment should be updated to say "Rules are stored in .agent/rules/ and can be triggered on-demand with /rule-name in the Antigravity interface" or similar.

+            for tag in rule.tags:
+                yaml_lines.append(f"- {tag}")
+


The comment says "tags for categorization (if Antigravity supports it)" which suggests uncertainty about the feature support. Either verify that Antigravity supports tags and remove the conditional comment, or remove the tags implementation if support is unverified. Compare with other format implementations like ClaudeCodeFormat which don't include tags.

Suggested change

# Optional: Add tags for categorization (if Antigravity supports it)

if rule.tags:

yaml_lines.append("tags:")

for tag in rule.tags:

yaml_lines.append(f"- {tag}")

# (No tags: Antigravity does not support tags in frontmatter)

Missing version field in the YAML frontmatter. All other IDE format implementations (CursorFormat, WindsurfFormat, CopilotFormat, ClaudeCodeFormat) include a version field using self.version. Consider adding yaml_lines.append(f"version: {self.version}") for consistency, unless Antigravity specifically doesn't support version metadata.

Incomplete frontmatter documentation. The docstring lists only description in the frontmatter (lines 18-20), but the implementation also includes tags (lines 60-64). Update the docstring to document all fields that may be included in the YAML frontmatter.

Suggested change

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!
