When Apps Script Time-Driven Triggers Quietly Run Out: Consolidating Gemini Automations into One Dispatcher
Apps Script caps you at 20 triggers per user and a daily total trigger-runtime budget. Here is how to stop your Gemini automations from silently dying as you add more, using a single dispatcher, a schedule table, and an external heartbeat.
Stop Losing Silently-Failed Jobs in Your Unattended Gemini API Pipeline
When an unattended Gemini API batch drops a single job in silence, you may not notice for days. Here is a minimal dead-letter store and a safe replay flow — with copy-paste code and the operational judgment that makes it work.
Audit Your Gemini API Key Restrictions Before the Unrestricted-Key Block Stops Your Automation
Since June 19, 2026, requests from unrestricted Gemini API keys are blocked. Here is how to check whether your key is affected and add restrictions without taking your production automation down.
When Gemini Computer Use Acts on a Stale Screen and Fails Quietly — Field Notes on Guarding the Loop
A Computer Use agent will click based on a screenshot taken moments ago, miss the real target, and throw no error. These are field notes on measuring those silent misclicks and stopping them with an observe-act-verify loop.
Stopping Runaway Costs Twice: Project Spend Caps Plus an App-Side Soft Limit
Pairing Gemini API Project Spend Caps (a monthly USD ceiling) with an app-side soft circuit breaker that trips before the hard cap. Includes a working Python and sqlite daily cost ledger.
The Morning a Preview Image Model Went Dark — Migrating to GA Gemini Image Models and Building a Deprecation-Resilient Pipeline
With gemini-3.1-flash-image-preview and gemini-3-pro-image-preview retired, here is how to migrate to the GA models and design an image pipeline that no longer gets caught off guard by deprecation dates — with code and cost math, plus video-to-image thumbnail automation.
Should You Move Your Agent Loop to Gemini's Managed Agents? Three Questions That Decide What Migrates
With Gemini API's Managed Agents in public preview, deciding between a self-hosted agent loop and a Google-hosted sandbox is now a real question. Three questions — execution environment, state ownership, and failure recovery — decide what migrates and what stays.
Routing Gemini by Pipeline Stage: Draft on Flash, Finish on the Top Tier
A record of reworking which Gemini model handles which stage of an automation pipeline, prompted by the general availability of Gemini 3.5 Flash and the rollout of 3.1 Flash-Lite. Includes a small router that splits work into draft, classify, and finalize stages, how the cost picture changes, and the guardrails I settled on.
Your Managed Agents Bill Has a Second Axis: Drawing a Budget Boundary Around Sandbox Runtime
Managed Agents in public preview bills for tokens and for how long its Google-hosted sandbox stays alive. A single hung run quietly drains your budget on that second axis. Here is a working Python design for wall-clock caps, idle teardown, and a concurrency ceiling.
Keeping Nightly Batches Alive After the Gemini CLI Stops Responding: A google-genai SDK Fallback
On June 18 the Gemini CLI stops answering requests. Here is a small fallback harness that probes whether the CLI can still respond and quietly reroutes unattended batch jobs to the google-genai SDK, built from my own automation.
Moving My Automation Off the Gemini CLI Before the June 18 Shutdown
On June 18, the Gemini CLI stops responding for hosted plans. Here is how I moved unattended scripts that called gemini from the shell over to the google-genai SDK, with structured output, retries, and cost measurement built in.
Watching the 'Voice' of Generated Text: Catching a Silent Default-Model Swap Through Style Drift
When the default model changes over your head, the output can stay factually correct while its voice quietly shifts. This walks through fingerprinting the style of generated text and detecting drift statistically, with a dependency-free implementation you can drop into your pipeline.
