// tested
Tested, not just written
Every release runs its full test suite against real tooling before it ships.
123 promtool timing scenarios: 100% errors pages within the predicted minutes at 99.9% and 99.5%
A sustained 2x burn opens a ticket and never pages; healthy traffic fires nothing for a full day
Every rule file passes promtool check rules; every PrometheusRule passes kubeconform -strict
Live run on Prometheus 3.14 + Grafana 13.2: every rule group healthy, every panel query checked
Report budget consumption matches the injected error ratio exactly, and replays from a fixture
108 unit tests for the parser, validation errors, decimal math and every template

Questions
+How is this different from Sloth or Pyrra?
Those turn a spec into rules, and this kit reads their specs so you can move over in one command. What it adds is the content: 21 SLI templates for real stacks, promtool tests proving the page fires at the predicted minute, dashboards, an error budget report, a policy template and the reasoning in writing.
+Does it overlap the Prometheus Alert Rules Pack?
No. That pack alerts on infrastructure symptoms and ships generic HTTP SLO alerts; this is the per-service SLO layer with your objectives, dashboards and reports. The series names differ, so both can run in the same Prometheus.
+What do I have to write per service?
About ten lines of YAML: service, objective, window, SLI template and its parameters. The generator writes the rules, alerts, CRDs, dashboard and report inputs.
+Can I use it for client work?
Starter and Pro are licensed for your own organization. Client and agency use requires Studio.
+Refunds?
If the kit doesn't work with a supported Prometheus and the troubleshooting guide doesn't fix it, contact us within 14 days for a refund.
