antigravity-exporter

name	antigravity-exporter
description	Export Cursor rules and skills to Antigravity format. Use when migrating rules from .cursor/rules/*.mdc to .agent/rules/*.md or copying skills from .cursor/skills/ to .agent/skills/. This skill operates from Cursor's perspective.

Antigravity Exporter

Export rules and skills from Cursor to Antigravity workspace.

Overview

This skill provides Python scripts to export Cursor content to Antigravity format:

• Rules: Convert .cursor/rules/*.mdc → .agent/rules/*.md
• Skills: Copy .cursor/skills/ → .agent/skills/

All scripts run from Cursor's perspective (located in .cursor/skills/antigravity-exporter/scripts/).

Quick Start

Export All Rules

python .cursor\skills\antigravity-exporter\scripts\export_rules.py

Export All Skills

python .cursor\skills\antigravity-exporter\scripts\export_skills.py

Preview Before Exporting (Dry Run)

python .cursor\skills\antigravity-exporter\scripts\export_rules.py --dry-run
python .cursor\skills\antigravity-exporter\scripts\export_skills.py --dry-run

Exporting Rules

What It Does

Converts Cursor rule files to Antigravity format:

• Reads .mdc files from .cursor/rules/
• Converts alwaysApply to trigger field
• Adds globs pattern for file-specific rules
• Writes .md files to .agent/rules/
• Normalizes line endings and formatting

Frontmatter Conversion

Cursor Format	Antigravity Format
alwaysApply: true	trigger: always_on
alwaysApply: false	trigger: glob or trigger: manual (auto-detected)
(no field)	trigger: manual

Smart Trigger Detection

The script analyzes content to determine the best trigger mode:

• React/TypeScript keywords (tsx, component, props) → trigger: glob, globs: *.tsx
• MUI keywords (@mui/material, mui) → trigger: glob, globs: *.tsx
• i18n keywords (i18n, translation, useTranslation) → trigger: glob, globs: *.tsx
• SVG keywords → trigger: glob, globs: *.tsx
• Default → trigger: manual

Usage Examples

Export all rules:

python .cursor\skills\antigravity-exporter\scripts\export_rules.py

Export single rule:

python .cursor\skills\antigravity-exporter\scripts\export_rules.py --single core.mdc

Preview changes:

python .cursor\skills\antigravity-exporter\scripts\export_rules.py --dry-run

Custom paths:

python .cursor\skills\antigravity-exporter\scripts\export_rules.py --source .cursor/rules --target .agent/rules

Example Output

[INFO] Exporting 5 rule(s)...

[SUCCESS] core.mdc -> core.md
[SUCCESS] mui.mdc -> mui.md
[SUCCESS] i18n.mdc -> i18n.md
[SUCCESS] svg.mdc -> svg.md
[SUCCESS] skeleton-query.mdc -> skeleton-query.md

Exported rules:

   - mui.mdc -> mui.md (trigger: glob, globs: *.tsx)
   - i18n.mdc -> i18n.md (trigger: glob, globs: *.tsx)
   - svg.mdc -> svg.md (trigger: glob, globs: *.tsx)
   - skeleton-query.mdc -> skeleton-query.md (trigger: glob, globs: *.tsx)

Exporting Skills

What It Does

Copies entire skill directories from Cursor to Antigravity:

• Reads skill folders from .cursor/skills/
• Excludes antigravity-exporter itself (prevents recursion)
• Preserves complete folder structure
• Copies all files (SKILL.md, scripts/, references/, assets/)
• Overwrites existing skills if names match
• Creates .agent/skills/ if needed

Usage Examples

Export all skills:

python .cursor\skills\antigravity-exporter\scripts\export_skills.py

Preview changes:

python .cursor\skills\antigravity-exporter\scripts\export_skills.py --dry-run

List available skills:

python .cursor\skills\antigravity-exporter\scripts\export_skills.py --list

Custom paths:

python .cursor\skills\antigravity-exporter\scripts\export_skills.py --source .cursor/skills --target .agent/skills

Example Output

[INFO] Exporting 5 skill(s)...

[SUCCESS] handle-api-service/ (create)
[SUCCESS] mui-docs/ (overwrite)
[SUCCESS] mui-mcp/ (create)
[SUCCESS] react-eslint/ (create)
[SUCCESS] skill-creator/ (overwrite)

Complete Workflow

To export everything from Cursor to Antigravity:

# 1. Export all rules
python .cursor\skills\antigravity-exporter\scripts\export_rules.py

# 2. Export all skills
python .cursor\skills\antigravity-exporter\scripts\export_skills.py

Or preview first:

# Preview rules export
python .cursor\skills\antigravity-exporter\scripts\export_rules.py --dry-run

# Preview skills export
python .cursor\skills\antigravity-exporter\scripts\export_skills.py --dry-run

# If satisfied, run without --dry-run
python .cursor\skills\antigravity-exporter\scripts\export_rules.py
python .cursor\skills\antigravity-exporter\scripts\export_skills.py

Command Reference

export_rules.py

python export_rules.py [options]

Options:
  --source DIR      Source directory (default: .cursor/rules)
  --target DIR      Target directory (default: .agent/rules)
  --single FILE     Export single file only (e.g., core.mdc)
  --dry-run         Preview without writing
  -h, --help        Show help message

export_skills.py

python export_skills.py [options]

Options:
  --source DIR      Source directory (default: .cursor/skills)
  --target DIR      Target directory (default: .agent/skills)
  --dry-run         Preview without exporting
  --list            List all skills in source directory
  -h, --help        Show help message

Notes

• Operating from Cursor: Scripts are located in .cursor/skills/antigravity-exporter/scripts/
• Safe operation: Source files in .cursor/ are never modified
• Automatic overwrite: Existing files/folders in .agent/ are overwritten without confirmation
• Self-exclusion: antigravity-exporter skill itself is excluded from skills export
• Directory creation: Target directories are created automatically if they don't exist
• Line endings: Rules are normalized to Unix line endings (\n)

Use Cases

Initial migration: Export all Cursor rules and skills to Antigravity when first setting up.

Incremental updates: After modifying rules or skills in Cursor, export them to sync with Antigravity.

Backup/sync: Keep Antigravity workspace in sync with Cursor workspace.

Testing: Use --dry-run to preview changes before applying them.

Troubleshooting

Issue: Script not found

Solution: Ensure you're running from project root and path includes .cursor\skills\antigravity-exporter\scripts\

---

Issue: Permission denied

Solution: Check file permissions, ensure .agent/ directory is writable

---

Issue: Files not triggering in Antigravity

Solution: Check frontmatter syntax, verify trigger: field is correct, test glob patterns

---

Issue: Content formatting broken

Solution: Check for special characters, ensure markdown is valid
