The body is lean and assumes Claude's competence — it does not explain what SLOs or error budgets are, and each SRE-workbook quote is brief and earns its place as an authoritative anchor.

Concrete Python test functions with specific assertions and numeric thresholds are provided, but they call undefined helpers (compute_sli, burn_rate_alert, BudgetTracker, release_gate, multi_window_alert, weekly_budget_report) whose implementations are not given, so the code is not fully copy-paste ready.

An explicit 8-step sequence runs from SLI/SLO definition through to stakeholder reporting, with each step's test assertions serving as validation checkpoints and bidirectional test guidance ("Test both directions", "Both must trigger").

The self-contained ~180-line body is organized into clear sections (When to use, Steps 1–8, Anti-patterns, Limitations, References) with single-level, clearly signaled references and no bundle files requiring deeper navigation.

Lists multiple concrete actions — "SLO + error-budget calculation", "burn-rate alerting", "monthly-budget exhaustion test", "freeze-trigger when budget consumed" — matching the comprehensive-actions anchor rather than merely naming a domain.

Explicitly answers both what (build error-budget gate tests with named sub-tasks) and when ("Use when an SLO and error budget are written down but nothing verifies that burn-rate alerts fire..."), so the when is explicit rather than merely implied.

Covers the natural SRE vocabulary a user would say ("SLO", "error budget", "burn-rate", "release freeze") with an explicit scenario trigger, matching the good-coverage anchor; it is not the level below because common variations of the niche terms are present.

Occupies a clear niche — error-budget/SLO enforcement testing — with triggers distinct from general monitoring or testing skills, making wrong-skill conflicts unlikely.
