Claude2anti

Claude to Antigravity (claude2anti)

Synchronize user-created Claude Code skills into Antigravity.

Scope

• Source: Claude user skills folder, auto-discovered from the local Claude environment
• Default source fallback: %USERPROFILE%\.claude\skills
• Target: %USERPROFILE%\.gemini\antigravity\skills

The sync logic should treat both SKILL.md and skill.md as valid skill entry files. When copying to Antigravity, normalize to SKILL.md so skill discovery is more reliable across environments.

When To Use

Use this skill when the user asks to:

• sync Claude skills to Antigravity
• update Antigravity skills from Claude
• replace an Antigravity skill with the Claude version
• copy one specific skill from Claude to Antigravity

Modes

Full Sync

For requests like:

• "sync all Claude skills to Antigravity"
• "update Antigravity skills from Claude"

Run:

powershell -ExecutionPolicy Bypass -File "<SKILL_ROOT>\scripts\sync-skills.ps1" -Mode full

Behavior:

• Creates a backup of existing Antigravity user skills
• Removes all Antigravity skills
• Copies all skills from Claude source folder into Antigravity
• Resolves junction/source links by copying real contents
• Normalizes skill.md to SKILL.md when needed
• Verifies sync result before cleaning up backup

Single Skill Sync

For requests like:

• "sync github-trending to Antigravity"
• "update md2tex skill to Antigravity"

Run:

powershell -ExecutionPolicy Bypass -File "<SKILL_ROOT>\scripts\sync-skills.ps1" -Mode single -SkillName github-trending

Behavior:

• Backs up the current Antigravity copy of that skill if it exists
• Replaces only that one target skill
• Normalizes skill.md to SKILL.md when needed
• Verifies sync result before cleaning up backup

Output Handling

The script prints a JSON summary. Report to the user:

• mode used
• source and target paths
• backup path
• synced skills
• skipped items
• any errors

Notes

• First try to detect Claude via where claude, then use the matching user Claude data directory
• Treat the discovered Claude skills directory as the source of truth for user skills
• If a skill exists in Claude as a junction/link, copy the real target contents into Antigravity
• skill.md and SKILL.md should both be accepted as source files
• Prefer writing SKILL.md in Antigravity targets
