Two critical issues for power users: system prompt bloat + premature auto-compression

Spending tens of hours weekly in Antigravity. Two issues killing productivity:

1. ~1200 lines of hardcoded system instructions that override my custom rules and can’t be removed. User rules should be supreme — let us disable system prompt sections we don’t need.

2. Auto-compression at 100-200k tokens on models with 1M context. No toggle, no threshold setting. Long sessions lose all accumulated context. Let users control this.

These compound — bloated system prompt eats tokens faster, triggering compression sooner. Both need user-facing controls.
