agentSonar runs two detections. The first stops runaway agents mid-run — loops, retries, subagent explosions — before they hit your bill. The second kicks in after each task: it analyzes what was spent, names the waste, and recommends the exact fix for the next run. Together they cut most agent bills by 20 to 40 percent.
Email founders@agent-sonar.com with your stack and your rough monthly agent spend.
Watches agent traffic as it happens. Detects loops, retry storms, subagent explosions — and halts the agent before the next call fires. Nothing to configure after install.
After each task completes, agentSonar analyzes spend by pattern — caching misses, redundant calls, oversized models — and surfaces the fix for the next run.

| agent step | calls | cache hits | cost | flag |
|---|---|---|---|---|
| Writer → drafting | 1,180 | 12% | $11,300 | low cache hits |

The Reviewer keeps bouncing work back to the Researcher. 312 round trips, $2,840 this month.
✓ auto-stop already catching thisSimple labeling tasks run on your most expensive model. A smaller model gets the same results on this task.
See the cheaper swapThe Writer's prompt changes on every call, so caching never kicks in. Only 12% of its calls hit the cache, against 84% everywhere else.
Keep the prompt opening the sameThe same file was read 1,240 times with nothing changed in between.
Reuse the first resultAfter each task completes, agentSonar analyzes what was spent and surfaces the exact patterns costing you money — with the fix ready for the next run. These are the ones we catch today, with more on the way.
Detected in real time. Auto-stop halts the agent before the next call fires — no code changes needed.
auto-stop · liveA prompt that runs every hour at $15/call costs $360/day. Cached, it's $24. We flag it and show the fix.
post-run analysisThe same tool called with identical inputs, over and over. We count the repeats and price the waste.
post-run analysisSimple tasks running on your most expensive model. We flag the step and suggest a cheaper swap that gets the same result.
post-run analysisSteps writing five times more than the next step reads. Shorter outputs, same quality, lower cost.
post-run analysisEvery agent codebase we instrument surfaces waste we hadn't named yet. New detections ship continuously. If you see something we don't catch, tell us.
growingA tool-call loop cost $437 overnight in one incident. A redundant-work storm fired 14,000 identical calls. One multi-agent loop ran 11 days and cost $47,000. The failures that break agents are the same failures that burn budget.
