# Beyond Observability

> Observability dashboards show you what happened. Coolhand goes further: it diagnoses the problem, proposes the
> fix as a pull request, and closes the loop with feedback and ROI reporting.

## The gap

Observability platforms are good at their job: traces, latency, token counts, error rates. What they don't do is
tell you what to change — someone still has to read the dashboard, form a hypothesis, write the fix, and validate
it. That interpretation-and-engineering step is the expensive, scarce part.

Coolhand is not an observability tool and isn't trying to become one. It watches production agents, and when
something's wrong, it proposes the fix as a pull request in your repo. You still decide — Coolhand just skips the
part where a human has to do the diagnosis from scratch.

## What "beyond observability" means

1. Observe
2. Diagnose
3. Propose fix (PR)
4. Collect feedback
5. Report ROI

## Who does the work, at each step

| Step | Observability platforms (Langfuse, Datadog) | Eval platforms (Braintrust) | Coolhand |
|---|---|---|---|
| See what happened | Platform (traces, logs, dashboards) | Platform (eval runs, scores) | Coolhand |
| Diagnose why | You, reading the dashboard | You, reading eval results | Coolhand |
| Collect human feedback | Usually not built-in | Manual annotation queues | Coolhand — passive capture from existing work |
| Write the fix | You | You | Coolhand proposes a PR; you review |
| Prove ROI to the business | You build the reporting | You build the reporting | Coolhand |

## When to use Coolhand alongside your stack — and when it stands alone

Many teams run Coolhand next to Langfuse, Braintrust, or Datadog: the observability tool stays the system of
record for traces and logs, and Coolhand watches the same production data to propose fixes and collect feedback.

If you don't have an observability tool yet, Coolhand can stand alone: enough visibility to know what's happening,
plus the fix and feedback loop most teams have to build themselves on top of a dashboard anyway.
