Most agents today break for reasons that have nothing to do with logic errors. They break because they are operating blind inside an environment that never stays stable long enough for static routing to survive.

Model behavior changes. Provider latency swings. Tools degrade silently. Rate limits appear out of nowhere. JSON parsing behaves differently under load. Every variable in this world is a moving target, and developers are expected to debug the fallout with logs that only capture a fraction of the real behavior.

The larger the system, the worse the blindness gets. Human optimization becomes retroactive and obsolete the moment a complex agentic system hits real production variability.

This is the bottleneck that is killing agent adoption. We built Kalibr to remove it.

Kalibr captures step-level telemetry on every agentic run. It aggregates that data into real system intelligence. It gives an agent a simple API to choose the safest, cheapest or fastest execution path based on what is actually working right now across the entire system.

One line of code. Agents stop failing for reasons you cannot control.

Why Agents Break

Modern multi agent systems generate thousands of branching LLM calls across GPT, Claude, Gemini, internal tools and random external APIs. None of these components are stable. All of them drift.

Developers have no way to answer basic questions: • Why did cost jump 300 percent this morning • Why did latency triple on the same workflow • Why is GPT hallucinating in a branch that worked yesterday • Why does the same agent behave differently on the same input • Where is the actual bottleneck in this chain of calls

Dashboards show you the body after it dies. They cannot stop the next death.

Human debugging is always late. By the time you notice the issue, optimization is already obsolete.

This category needs real-time, runtime intelligence, not postmortems.

What Kalibr Does

1. Automatic Telemetry Capture

Every OpenAI, Anthropic, Google and local model call is intercepted without changing your workflow. Kalibr captures: • duration • token usage • cost • success or failure • model and provider • parent/child relationships • timestamps

Your agent code stays the same. The SDK wraps the calls. This is the base layer that makes everything else possible.

2. Distributed Tracing for Multi Agent Systems

Kalibr reconstructs the full execution graph for every workflow. If a branch collapses, you see: • where it collapsed • why it collapsed • which upstream decisions led to it • what downstream effects it triggered

Datadog-style tracing, but built for agentic workloads instead of microservices.

3. Intelligence API

This is the core.

Before an agent executes a step, it can ask Kalibr one question: What is working right now.

Not last week. Not whatever routing file you committed months ago. Right now.

Kalibr returns model recommendations based on: • real time success rate • p50 and p95 latency • cost drift • volatility • error patterns • recent failures across the entire system

Routing becomes a data driven decision instead of guesswork.

4. TraceCapsules for Handoffs

When Agent A hands off to Agent B, B inherits the full history of the execution: • which models were used • how much was spent • what failed • what succeeded

The capsule travels with the workflow until completion. Each hop extends the record. You get end to end transparency by default.

*5. Shared Learning Across Agents * One agent fails. Kalibr logs it. The next agent avoids the same mistake.

No retraining pipeline. No shared code. No manual intervention.

The intelligence layer updates continuously as the system runs. This is how you stop pathological failures from repeating forever.

Why This Layer Is Not Optional

Agents operate inside unstable environments: • model performance fluctuates • costs shift • rate limits spike • external tools degrade • inputs are chaotic • outputs vary across runs

All of this happens faster than any human can react, and all of it affects reliability, correctness and cost.

Static routing dies on contact with reality. Manual debugging does not scale. Model vendors will never expose cross-provider insights. Dashboards cannot optimize future decisions.

If agents are going to survive real workloads, they need a shared brain. Kalibr is that brain.

The Outcome

Without Kalibr • agents run blind • failures repeat endlessly • cost spikes appear without warning • drift is unexplained • every agent learns in isolation • scale collapses reliability

With Kalibr • agents choose optimal paths automatically • failures turn into system wide learning • real time visibility replaces guesswork • routing becomes adaptive and stable • cost and latency flatten • reliability improves as the system runs ** We are building the intelligence substrate agentic systems need to function at scale.**

Install the SDK. Wrap your LLM calls. Let your system learn from itself.

Agents have never had foresight. Now they do.
