Antigravity Flush

A VSCode extension that adds a simple "Flush Context" button to clear Antigravity conversation data to fix Opus model crashes caused by token checkpoint truncation.

Features

Status Bar Button: One-click "🗑️ Flush Context" button in the status bar
Keyboard Shortcut: Ctrl+Shift+Alt+F (or Cmd+Shift+Alt+F on Mac)
Confirmation Dialog: Prevents accidental data loss
Clears All Context: Removes conversations, context_state, and brain session data

Why You Need This

The Antigravity IDE has a hardcoded 7500 token "Summarization Threshold" for checkpoint summaries. This is particularly problematic for the Opus model. When conversations get long (92+ messages), the IDE tries to summarize everything which can cause:

Truncation errors
Malformed JSON requests
400 Bad Request errors

This extension lets you quickly flush the context and start fresh, resolving the crash immediately.

New Features (v1.1.0)

MCP Warning: Automatically warns if you have too many MCP commands (>20) registered, which can affect performance.
Auto-Reload: Option to reload the window immediately after flushing for a clean state.
