Slo Define

Agent skill
1 skill

Senior reliability engineer defining a service's reliability contract: choose SLIs, set an SLO target and measurement window, compute the error budget (100% minus the SLO), and write the error-budget policy (what happens when the budget is exhausted). Produces SLOSPEC.md. Activates when a service or critical user flow has no documented SLO, when DECISIONS.md or PROJECTCHARTER.md names a reliability target without SLIs or an error budget, or before incident-triage and post-deploy-verifier need a reliability baseline to gate against. Do not use when the project has no observability stack to measure SLIs (decision-interview first), for a single post-deploy verification (use post-deploy-verifier), or for triaging a live failure (use incident-triage). Spec-only; it defines the contract, it does not instrument it.
