⚡ Antigravity Proxy v1.2.0 — Context Compactor, Live Google Search & Windows 1-Click Installers

We are excited to release Antigravity Proxy v1.2.0! This major update introduces our intelligent Context Compactor Engine, official Claude Code /compact interception, native Google Grounding live web search, 1-click installers for Windows, and comprehensive standalone package builds for all major platforms.

🌟 What's New in v1.2.0

🗜 1. Context Compactor & Auto-Summarization Engine

  • 80% to 98% Token Reduction: Automatically monitors session token counts and compresses large conversation histories down into a clean ~1,500-token structured context, allowing coding sessions to run indefinitely without hitting Google's hard limit of 1,048,576 tokens (Error 400 Context Overflow).
  • Official Claude Code /compact Interception: Intercepts Claude Code's manual /compact and /autocompact commands, routing summarization to gemini-3.1-flash-lite using the official 9-section summarization schema while preserving 100% of your primary model quota.
  • Dynamic Dashboard Controls: Interactive threshold slider (30k–200k tokens) and configurable uncompressed message preservation (Preserve Last Messages: 4–16 msgs) directly from the Web UI.

🌐 2. Live Web Search & Google Grounding (Vertex AI)

  • Native Google Search: Empowers coding assistants (like Claude Code) with real-time web search capabilities via Google Grounding without requiring paid third-party search API keys.
  • Concurrent Multi-Engine Fallback: Automatically queries DuckDuckGo, Bing, and Brave in parallel with domain filtering (site:), URL deduplication, and citation generation.

⚡ 3. Intelligent Background Task Optimization

  • Quota Preservation: Automatically detects non-interactive background tasks (title generation, context compaction, checkpoints) and transparently routes them to gemini-3.1-flash-lite with a 0-thinking budget, saving your primary reasoning model quota.

🛡 4. Zero-Delay Recovery (Retry-After: 2)

  • Prevents Claude Code from locking up in 4-minute exponential backoff retry loops during transient upstream errors by injecting standard Retry-After: 2 headers for instantaneous 2-second failovers across pool accounts.

💻 5. One-Click Installers & Cross-Platform Binaries

  • Added instant 1-click installer scripts for Windows PowerShell (install.ps1) and Windows Command Prompt (install.cmd), automatically setting up the executable in the user's system PATH.
  • Full matrix build support: Windows x64, Linux x64/ARM64, macOS ARM64 (Apple Silicon), and macOS Intel (x86_64).
  • Standalone Python Wheels (.whl) and Source Distributions (.tar.gz) published alongside every release.

🧹 6. Minimalist Logging & Protocol 1.1.23

  • Updated User-Agent to the official Antigravity CLI 1.1.23 protocol (cl=974125021).
  • Stripped console clutter and emojis from standard user logs; refined the --debug flag for full technical developer tracing.
  • Updated Cloudflare Edge Worker (cloudflare/worker.js) to support the 1.1.23 protocol and fast error recovery.
