Developers just unlocked the next level of clean code in 2025. Agentic AI’s bug detection no longer waits for crashes; it predicts, reasons, and blocks errors before they ever reach users. At AWS re:Invent, Sentry CEO Milin Desai revealed how his company’s new “Seer” reasoning engine turns mountains of production data into proactive shields that catch hundreds of thousands of bugs pre-launch.
Sentry started as an error-monitoring tool, but Seer flips the script. The system watches real user sessions, traces, logs, and performance data. Then it reasons like a senior engineer: it spots the root cause with 95% accuracy and either writes the fix automatically or stops risky code from merging.
How Agentic AI’s Bug Detection Actually Works Today
Sentry’s Seer layer delivers game-changing prevention. Here’s what teams gain right now:
- 95% accurate root-cause analysis in seconds instead of hours
- Automatically blocks bad commits before they hit production
- Writes fix suggestions or full PRs through in-house coding agents
- Prevents hundreds of thousands of real bugs from shipping monthly
- Uses live telemetry (traces, logs, replays) across web, mobile, and backend
- Integrates directly into existing developer workflows and tools
Desai told theCUBE: “We are catching hundreds of thousands of bugs right now – preventing them, not catching them. Preventing them from getting shipped is a whole different value play.”
The shift from observability to reasoning by Agent AI’s bug detection marks a turning point. Traditional tools only screamed when something broke. Agentic AI’s bug detection now thinks ahead: it flags dangerous patterns, understands context, and acts autonomously.

Developers still write the features, but AI handles the safety net. Desai predicts every coder will soon work AI-assisted, delivering faster releases with dramatically higher quality.
As companies race to ship more code than ever, tools like Seer prove agentic AI’s bug detection isn’t coming, it’s already here, quietly stopping tomorrow’s outages today.
