The thirty-day retention everyone quotes for Grounding with Google Search went stale last February. It's up to 3 days of debug logs now. The old thirty days moved to Maps grounding—same provider, opposite posture: caseywest.com/governed-gro...

Governed Growth, Part 2: The Retention Window That Quietly Shrank

On February 23, 2026, Google quietly made the retention terms for Grounding with Google Search better: the window dropped from thirty days to up to three, and what's kept narrowed from your prompts an...

Your agent can't really search the web. It guesses from training, or scrapes a snippet. gemini-search-mcp gives it one tool: a real Google search, run through Gemini, answered with the sources it used. One install, one static binary: https://github.com/cwest/gemini-search-mcp

Picked the small Gemini model for my search tool. Two newer models shipped, so I re-ran the eval—four models, one run. The small one still wins. The biggest came last on everything, at ~140x the cost. caseywest.com/building-gem...

"We approved the model" and "we approved the model's web search" are two different decisions. Most platforms treat them as one—so one line in a PR opens a data path nobody chose. Part 1 of a 5-piece run. Follow along: caseywest.com/governed-gro...

They swapped the model mid-experiment. The café failed the same way. So the model wasn't the problem. It shipped with no spend cap and no approval gate—the seatbelts you install on day one. The proof and the five fixes: www.linkedin.com/pulse/ai-did...
