The query count in our snapshot drawer went blank, and the unit test for that request kept passing. When we went looking in recorded traffic, the API gateway had rejected that request 210 times in a single recording. Every one of those rejections came back as 200 OK. So we searched the rest. We record our own API gateway with Speedscale, and two recording windows from November 3 to 5 (about 38 hours between them) held 1,238 responses with gRPC status INVALID_ARGUMENT. All 1,238 returned HTTP 200.

Explore how AI coding assistant approvals can create security risks, and learn why content-bound trust, signed configurations, and approval reviews matter. This is part two in a series. What you actually bind to when you click “yes” and why the binding outlives the thing you trusted.

Our internal AI applications repeatedly send the same system instructions, tool definitions, and conversation history to large language models (LLMs). Prompt caching lets models reuse this data from previously processed input, reducing the cost of handling repeated content. But while investigating our LLM costs, we found applications that weren’t benefiting from caching, even when it appeared to be enabled.
