執行需求
以遠端 streamable HTTP 端點形式執行於 utility-matrix.com;未宣告任何套件、帳號、API 金鑰或環境變數。需要能連線至該端點的網路。
安裝前請注意
結果為依固定輸入與公開價格或基準區間所做的模型估算,並非即時帳單或漏洞資料;已知漏洞檢查器僅使用歷史整理的範例,無法證明某個套件目前安全或存在漏洞。金鑰掃描會把貼上的文字傳送到第三方端點,請勿提交真實憑證。

輸入參數slo_pct必填window_daysconsumed_minuteswindow_elapsed_days

slo-burn-rate-calculator

SLO Burn Rate Calculator

Use this when a user asks how fast they are burning their error budget, or whether their current error rate will exhaust their SLO window. Takes error count, total requests, SLO target, and observation window. Returns burn rate and budget consumption per hour.

incident-cost-calculator

Incident Cost Calculator

Use this when a user asks what an outage or incident cost, or wants to calculate the financial impact of downtime. Takes hourly revenue, downtime duration, and affected percentage. Returns revenue impact, engineering cost, and total incident cost in dollars.

reserved-instance-breakeven

Reserved Instance Breakeven Calculator

Use this when a user asks whether to buy Reserved Instances or stay on On-Demand, or how long an RI takes to pay for itself. Takes On-Demand and RI monthly costs plus optional upfront fees (0 when omitted). Judges the 1-year and 3-year terms separately and returns each break-even month and net saving. It recommends a term only when that term saves money over its own length, and prefers 3 years only when it beats three 1-year terms over 36 months at current prices.

availability-sla-calculator

Availability SLA Downtime Calculator

Use this when a user asks what a specific availability percentage (like 99.9% or 99.99%) means in downtime minutes per month or year. Converts availability SLA percentage to exact downtime budgets: annual, monthly, weekly, and daily.

輸入參數availability_pct必填

apdex-score-calculator

Apdex Score Calculator

Use this when a user asks about their Apdex score or wants to measure user satisfaction with response times. Takes satisfied, tolerating, and total request counts; satisfied plus tolerating may not exceed total. Returns the Apdex score (0–1) and its rating on the published five-band scale: excellent, good, fair, poor or unacceptable.

輸入參數total必填satisfied必填tolerating必填

dora-metrics-calculator

DORA Metrics Calculator

Use this when a user wants to benchmark an engineering team against DORA metrics. Takes deploys per month, lead time in hours, change failure rate in percent and, optionally, time to restore in hours. Classifies each metric as elite, high, medium or low against fixed benchmark bands; an omitted restore time is reported as unknown and the overall profile is marked partial rather than assumed.

pipeline-cost-calculator

CI/CD Pipeline Cost Calculator

Use this when a user asks how much their GitHub Actions CI/CD pipeline costs per month.

Uses GitHub list prices for standard hosted runners effective 1 Jan 2026 and GitHub Free's 2,000 included minutes for private repositories, drawn at list price. Self-hosted minutes carry no GitHub charge.
