bug(target): antigravity target fails to load skills on Windows due to wrong default path and sync mode

Environment

• OS: Windows 11
• Target: antigravity

---

Symptoms

Skills installed by skillshare for the antigravity target do not appear in Antigravity. The agent cannot load or execute any synced skill.

---

Root Cause

The default target configuration for antigravity contains two errors:

1. Incorrect Target Path

   • Default configured path: ~/.gemini/skills/
   • Actual path read by Antigravity: ~/.gemini/config/skills/

2. Incompatible Default Sync Mode on Windows

   • Default sync mode: merge (creates symlinks)
   • Behavior: Antigravity cannot traverse Windows directory symlinks and returns an Incorrect function error. Antigravity requires real directories.

---

Workaround for Users

1. Edit %APPDATA%\skillshare\config.yaml (or ~/.config/skillshare/config.yaml):

   targets:
     antigravity:
       mode: copy
       skills:
         path: C:\Users\<username>\.gemini\config\skills

2. Run the commands to apply the mode and sync files:

   skillshare target antigravity --mode copy
   skillshare sync --force

3. Open a new session in Antigravity to load the copied skills.

---

Proposed Fix for skillshare

Update the built-in target definition for antigravity in skillshare:

1. Change the default skills path for antigravity from ~/.gemini/skills to ~/.gemini/config/skills.
2. Change the default sync mode for antigravity on Windows from merge to copy.
