Positive Developments

TGIF! Thank god it's features, here's what we shipped this week:

The headliner: classifier labels now have polarity, so when a signal trends up, you can finally tell whether to celebrate or panic. The outlook is decidedly positive—let's get into it.

Added

• Classifier Label Polarity - Classifier labels can now be marked as positive, negative, or neutral, giving every trend the context it was missing. A spike in successful resolutions and a spike in safety violations may both point up, but your Signals can finally tell which direction is actually good. No more guessing whether up and to the right deserves applause or an alarm. Positive identification.
• Async AI Connections - AI Connections no longer have to sit on the line while long-running agents finish the job. Asynchronous responses let agents keep working beyond a single request window, then return their results when they're ready—without timeouts cutting the conversation short. Good things come to agents that await.
• Zero-Config Signals & Online Evals - New projects can go straight from sending traces to seeing Signals and online evals work out of the box. Sensible defaults are ready from the first trace, so there is nothing to configure before production quality starts showing up. Send first, set up never. Signal and deliver.
• Cost Insights by Feature - Cost Insights can now break project spend down by feature, showing exactly which parts of your product are running up the tab. Follow the money from the project total to the feature responsible and optimize where it actually counts. Every token leaves a paper trace.
• Annotation Date Filters - Annotations can now be filtered by date, making it easy to focus on a specific review window, compare periods, or find the label you know someone added last Tuesday. Your annotation history just became a lot less timeless. Date your data.
• Metric Collection Sample Rates - Metric collections can now sample incoming traffic at the rate you choose, keeping online evaluation representative without evaluating every trace. Turn the volume down without losing the tune. Sample and hold.
• Report Template Page Breaks - Report template sections can now start on a new page, giving every major section the clean entrance it deserves in exported reports. No more headings stranded at the bottom of the previous page. Time to turn over a new leaf.
• Trace Detail Icons - Provider and integration icons now appear on trace details, so you can spot the services behind a span at a glance. Yes, icons made the changelog. They're small, they're obvious, and somehow we all survived without them until now. Tiny feature, big icon energy.

That's the drop for this week—see you next Friday.
