Replay a bad run instead of reconstructing it.

When an agent does something wrong, the question is always the same: what actually happened. Without traces the answer is reconstruction from logs and memory. We instrument the whole run, every model call, every tool invocation, every retry, with cost and latency attached to each step, so a bad run is something you open and watch rather than argue about.

Built for production, not the demo.

01 / OBSERVABILITY

Tracing and monitoring for LLM and agent systems, for teams who cannot explain what happened.

For teams who cannot explain what happened. Full execution traces, tool-call success rates, cost and latency per step, and drift over time.

Usually shipped with

  • Production AI engineering
  • LLM evaluation
  • Model routing and cost control

Not a bundle to buy. Whichever you start from, the engagement covers what the build actually needs.

02 / Scope

What we build.

  • Full execution traces across model calls, tools and retries
  • Tool-call success rates, so a failing integration is visible
  • Cost and latency attributed per step, not per request
  • Drift and quality tracking over time, not only at release
  • Alerting tuned to the failures that matter rather than every anomaly
  • Traces in Langfuse, LangSmith or your existing OpenTelemetry backend, not a dashboard you cannot export from

03 / Outcomes

What you can ship.

  • Any run replayable end to end
  • Cost attributable to the step that spends it
  • Failures caught by monitoring instead of by a customer

04 / Deliverables

Artefacts, not activities.

  • Instrumented runsFull traces across models, tools and retries, in your own observability stack.
  • Cost and latency attributionPer-step breakdown, so spend is traceable to a cause.
  • AlertingThresholds on the failure modes that matter, wired to where your team already looks.

06 / Why us

Traces, not logs

A log tells you something happened. A trace lets you watch it happen again. On Skionis the validation loop is inspectable step by step, which is why engineers trusted it against a live AWS account.

Cost attributed to the step that spends it

Per-request cost is an average that hides the one tool call responsible for most of the bill. Step attribution is what makes routing decisions possible later.

Failed runs become test cases

The traces feed the eval set, so every production failure is a regression test rather than a story someone remembers.

A path from your problem to production.

  1. Week 1

    Instrument the whole run

    Every model call, tool invocation and retry, with the inputs and outputs that make a run replayable rather than merely counted.

  2. Week 1-2

    Attribute cost and latency per step

    Per-request totals hide the step that spends the money. Attribution is what turns a bill into a decision.

  3. Week 2-3

    Alert on what matters

    Tool-call failure rates and quality drift, not every anomaly. An alert nobody acts on trains everyone to ignore alerts.

  4. Week 3-5

    Close the loop with evals

    Traces feed the evaluation set: the runs that went wrong become the cases you test against.

Production-proven

Built by engineers who've already shipped this in production.

The questions buyers actually ask.

Can this use the observability stack we already have?

Usually yes. We emit OpenTelemetry where your tooling accepts it, rather than adding another dashboard nobody opens.

What does it cost to store all this?

Sampling handles it. Full traces on failures and a sample of successes gives you the debugging value without the volume.

Is this different from normal APM?

Yes, in what it records. A request duration tells you nothing about why an agent chose the wrong tool. The unit of interest is the decision, not the HTTP call.

Do we need this before we have traffic?

Instrument early, alert later. Retrofitting traces onto a system already in production is significantly more work than building them in.
