A Risk-Tiered Approval Gate for Gemini Function Calling
Handing full autonomy to an agent is unnerving. This walks through a Gemini function-calling loop that routes tool calls into auto-run and hold-for-approval by risk tier, then feeds the result back to the model after a human signs off.
When Your Gemini Agent Has Three Tool Routes and Quietly Picks the Wrong One
Put Function Calling, Code Execution, and Grounding into one agent and the model will sometimes choose the wrong route, while the output still looks perfectly plausible. Here is how I instrument route selection and correct it with phase separation and verification gates, with working code.
Stopping Gemini API Function Calling Loops: Why They Happen and How to Break Them
Your tool-calling agent keeps invoking the same function and never finishes. Here is how to diagnose the loop and bake stop conditions into your prompt, code, and tool responses — including catching regressions when the default model changes and detecting result-based stalls.
Restarting a Long Agent Run From Where It Broke — A Step-Ledger Design for Gemini 3.5 Flash Long-Horizon Tasks
Gemini 3.5 Flash is good at long-horizon tasks, but when a 40-step run dies on step 29, you usually start over. An append-only step ledger gives you resume, idempotency, and audit in one place. Here is the design with working Python and measured results.
