Purpose

Turn "we need 99.9% uptime" into a measurable, actionable reliability contract. Define what to measure (SLI), what to aim for (SLO), how much failure is budgeted (error budget), and when to alert before the budget burns out (burn rate alerts).

Trigger

Apply when:

• "define SLO", "set reliability target", "error budget", "服務等級"
• "what should our uptime target be", "burn rate alert", "99.9%"
• Service is going to production and needs a reliability baseline
• Incident postmortem identified the need for formal SLOs

Do NOT trigger for:

• Setting up monitoring dashboards — use observability-designer instead
• General infrastructure setup — use ci-cd-pipeline-builder instead
