It Did Things I Never Asked For — Binding an Agent's Task Scope With a Contract
Ask it to fix a button color and you get a refactor, renames, and a dependency bump too. This is a scope problem, not a permission one. Here is a contract that stops at the scope boundary and asks.
Antigravity and Gemini CLI — Why the June 2026 Sunset Changed the Comparison
Gemini CLI's consumer offering ended on June 18, 2026, and its terminal role passed to the Go-based Antigravity CLI. With the premise changed, here is how the two design philosophies differ and what to check before you migrate.
When Streaming Works Locally but Arrives All at Once in Production — Field Notes on Proxy Buffering and Silent Stalls
Stream Gemini through Antigravity over SSE and it flows token-by-token on localhost, then freezes for seconds and dumps the whole answer in production. Field notes on measuring the stall first, then killing proxy buffering, idle disconnects, and reconnect-driven double generation.
Confirm Your Unattended Runs Survived a Point Release in 30 Seconds
As Antigravity ships point releases at a fast clip, how do you stop scheduled runs from quietly breaking after an update? Here is a lightweight smoke test that detects regressions against a golden output and rolls back automatically when it diverges.
Where to Start Reading an Unattended Agent's Changes — A Digest for Re-Entry
How do you review the pile of changes an unattended agent left overnight? Not the full diff, not the chat log — a re-entry digest grouped by risk class.
Turning Faster Substring Search into Solid Grounding for Agents in Large Repos
Antigravity's substring search got faster. Rather than stopping at perceived speed, here is how to wire it into a search design that hands agents exactly the right context in a huge codebase, with concrete steps and pitfalls.
Hearing the Audio an Agent Made, Right Inside the Conversation
A recent Antigravity point release added inline audio rendering in the conversation view. Here is how playing agent-made audio in place changes the way I audition sound assets for my apps.
The Day My Own Skill Stopped Firing — When the Built-in Guide Skill Collides With Yours
Since the built-in Guide skill arrived, custom skills started getting skipped or double-fired. Here is how to observe which skill is chosen, and how to settle the conflict through descriptions and naming.
Treating Built-in Guide Skills as Design Assets, Not Throwaway Prompts
Antigravity v2.2.1 added built-in Guide skills. Here is a concrete structure and set of judgment calls for running them as version-controlled, shared design assets instead of one-off instructions.
Prune an Antigravity plan before you approve it
Instead of approving a Planning-mode plan wholesale, cut the one risky step and keep the rest. A field-tested look at partial plan editing from a solo developer's desk.
The Day the Article I Asked It to Format Became the Agent's Instructions
When you run an unattended content-formatting pipeline with Antigravity CLI, instruction-like text buried in the file you are processing can hijack the agent. Here is how I separate the instruction channel from the data channel and add an output-scope acceptance gate to reject anything out of bounds.
Before AI Studio's Gradle and AGP Versions Quietly Break Your Existing App
When you drop an AI Studio-generated Kotlin/Compose screen into an existing Android app, the AGP, Kotlin, and library versions drift and the build breaks silently. Here is how to pin a single source of truth with a version catalog and add a gate that inspects the generated declarations at the import boundary, with measurements and code.
