Keep a Tamper-Evident Audit Log of Your Autonomous Agent's Actions
To record the decisions and actions an Antigravity agent takes autonomously in a form you can trace and verify later, design an append-only audit log whose hash chain detects tampering. Includes the implementation.
Pass Your Agent's Structured Output Downstream With Schema Validation and Bounded Repair
Before the JSON an Antigravity agent returns flows straight into downstream automation and causes an incident, build a safe boundary with JSON Schema validation and a turn-limited repair loop. Includes the implementation.
Pin Your Agent's Output With Golden Snapshots Before Switching Models
When Antigravity's engine moves to Gemini 3.5 Flash, an agent's output can drift silently. This walks through a golden-snapshot regression gate that catches the drift, with the actual test code and a migration-day checklist.
Turning a throwaway prompt into a reusable sub-agent
When a one-off prompt to an Antigravity 2.0 dynamic sub-agent works beautifully, it usually vanishes into your chat history. Here is how to capture it as a reusable definition, with the actual file layout and the distillation steps.
Spending Less on Failure Without Swallowing It: A Retry Budget for Agents Built Around Gemini 3.5 Flash
A design that separates an agent's retries from quietly swallowing errors: classify the failure first, then retry within a budget. Grounded in the speed and price of Gemini 3.5 Flash, with per-task caps, logging, and a weekly tightening routine.
Treating the Managed Agent as a Cost-Capped Throwaway Worker: Isolating Untrusted Input from Production
How to use the Managed Antigravity Agent, now in Gemini API public preview, as a throwaway worker that is born and discarded per request. Cost caps, isolation, and idempotency with implementation steps.
Matching Antigravity 2.0's Three Layers to Development Phases: Explore, Iterate, Operate
How I assign Antigravity 2.0's desktop, CLI, and SDK to development phases instead of features, with concrete handoff patterns between layers and the production pitfalls I hit.
Running Multiple Repositories in Parallel with Antigravity 2.0 Projects and Worktrees
Combining Antigravity 2.0 projects with git worktrees to run several repositories in parallel safely. From isolating agent workspaces to avoiding conflicts and connecting to scheduled execution, organized from real work.
Calling a Managed Antigravity Agent from the Gemini API: Design Notes on the Preview Model
antigravity-preview-05-2026, now in public preview on the Gemini API, is a Managed Agent that plans, runs code, edits files, and browses the web autonomously inside a sandbox. Here is how it differs from rolling your own orchestration, and where to draw the line.
