As context windows swell past tens of thousands of tokens with terminal traces, compiler diagnostics, and speculative file edits, an agent’s attention mechanism degrades. Critical system constraints, architectural decision records (ADRs), and testing invariants drift into the periphery, leading to hallucinations, ignored instructions, and silent error suppression.</p> <p>To solve this in Google Antigravity, we built the <strong><a href="https://github.com/vinhthang/antigravity-attention-guard-plugin">Antigravity Attention Guard Plugin</a></strong>—a deterministic runtime firewall that enforces subagent delegation, sandboxed tool execution, and cryptographic ledger tracking.</p>
