"""Bridge protocol — communication between Discord bot and Antigravity.

|
|
Bridge directory: ~/.gemini/antigravity/bridge/
|
|
Structure:
|
|
bridge/
|
|
pending/ ← Bot writes approval requests for Discord
|
|
response/ ← Bot writes user responses from Discord
|
|
commands/ ← Bot writes user text input from Discord
|
|
|
|
Protocol:
|
|
1. VS Code Extension detects pending approval → writes JSON to pending/
|
|
2. Bot reads pending/ → sends Discord message with ✅/❌ buttons
|
|
3. User clicks button → Bot writes JSON to response/
|
|
4. VS Code Extension reads response/ → executes action
