What is the 100th tool call problem in CI agents?

It's when AI agents exceed 100 tool invocations—like code runs or API hits—in production CI/CD, looping endlessly without completing tasks, due to missing stop conditions.

Why do CI agents fail in production but not demos?

Demos use simple, capped tasks; prod involves messy repos, flakey externals, and infinite recursion on errors—pushing calls past budgets.

How to prevent the 100th tool call problem?

Enforce step/tool/time budgets and no-progress termination: cap at 50-100 calls, timeout at 10 mins, kill on repeated states.

The 100th Tool Call Trap: Why CI Agents Implode in Production

Everyone thought AI agents would own CI/CD pipelines. Nope—they hit the 100th tool call wall, looping into oblivion and wasting dev cycles.
