Service Level Indicators (SLIs)</h3>\n<p>Compute each SLI from <code>GET /api/analytics</code> / <code>GET /api/stats</code>:</p>\n<ul>\n<li><strong>Completion rate</strong> = completed sessions / total sessions (from <code>sessions_by_status</code>; count <code>active</code>/<code>running</code> as in-flight, exclude them from the denominator if still open).</li>\n<li><strong>Tool success rate</strong> = <code>PostToolUse / PreToolUse</code> (capped at 100%).</li>\n<li><strong>Error rate</strong> = <code>APIError / total_events</code>.\nWithin a window, derive the numerators/denominators from <code>daily_events</code> / <code>daily_sessions</code>.</li>\n</ul>\n<h3>2. SLO Scorecard</h3>\n<p>For each SLI, compare to its target and mark MET ✅ or BREACHED ❌.</p>\n<h3>3. Error Budget</h3>\n<p>For each objective, report the <strong>error budget</strong> and how much remains:</p>\n<ul>\n<li>Budget = <code>1 − target</code> (e.g., 1% for a 99% target).</li>\n<li>For \"higher-is-better\" SLOs (completion, success): remaining = <code>(observed − target) / (1 − target)</code>.</li>\n<li>For \"lower-is-better\" SLOs (error rate): remaining = <code>(target − observed) / target</code>.</li>\n<li>A negative result means the budget is exhausted — report how far over (e.g., \"2.7× over budget\").</li>\n</ul>\n<h3>4. Breach Drill-Down</h3>\n<p>For any breached SLO, list the sessions contributing most to the breach (most failed tools or most APIErrors) via <code>GET /api/events?session_id=X</code>.</p>\n<h2>Output</h2>\n<ul>\n<li>A Markdown scorecard table: SLI | observed | target | status | error budget remaining.</li>\n<li>Rates as percentages to 2 decimals; any currency in USD to 4 decimals.</li>\n<li>Cite exact counts and <code>session_id</code> values — never fabricate numerators or denominators.</li>\n<li>End with the SLO most at risk and the single action that would recover the most budget.</li>\n<li>Read-only: only report what the API returns.
