The method
Reliability without becoming an evals team.
Connect once. Unviber keeps testing as your skill, its dependencies, and the models underneath it evolve.
02
We build the pressure test
Unviber generates realistic scenarios, awkward edge cases, and failure conditions tailored to what the skill promises.
03
Wake up to the signal
Runs happen autonomously. You get clear regressions, replayable traces, and the exact change that caused each drift.
Example output
One honest view of every skill.
Signal over dashboards. See what changed, why it matters, and where to look next.

Designed for change
The ground moves. Your quality bar shouldn't.
Models update, tools fail, and instructions drift. Unviber turns those moving parts into a stable release signal your whole team can understand.

FAQ
The useful questions.
What exactly is a skill?
Any packaged instruction set, agent capability, or tool-driven workflow with behavior you want to keep reliable as models and dependencies change.
Do I need to write my own evals?
No. Unviber starts from the skill's stated contract and generates a useful baseline. You can add your own scenarios whenever domain expertise matters.
Does it run in pull requests?
That is the goal for the Team plan. Scheduled runs watch for model drift; pull-request runs catch regressions before a skill change reaches users.
Is the pricing final?
Not yet. This is proposed early-access pricing and will evolve with the beta. Early users will get notice before anything changes.
