Use this when a user asks about their SLO error budget, remaining error budget, or burn rate. Given SLO percentage and window, returns budget minutes remaining, burn rate multiplier, and status (Under…

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 observatio…

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 imp…

reserved-instance-breakeven

Use this when a user asks whether to buy Reserved Instances or stay on On-Demand, or how long until an RI pays for itself. Takes On-Demand and RI monthly costs plus upfront fee. Returns break-even mon…

availability-sla-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: an…

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. Returns Apdex score (0–1) and perfor…

dora-metrics-calculator

Use this when a user wants to benchmark their engineering team against DORA metrics, or classify their deployment frequency and lead time. Takes deploy frequency, lead time hours, change failure rate,…

pipeline-cost-calculator

Use this when a user asks how much their GitHub Actions CI/CD pipeline costs per month, or wants to compare runner costs. Takes average job duration, jobs per run, monthly run count, and runner type. …

Use this when a user asks how many database connections to configure. Uses the same max_connections, app server count, database cores, average query duration, and peak RPS model as the browser calcula…

cluster-capacity-calculator

Use this when a user asks for Kubernetes cluster capacity. Uses the same node vCPU, node memory, node count, system reserve, and target utilization model as the browser calculator.

precision-recall-f1-calculator

Use this when a user asks about their ML model precision, recall, F1 score, or F-beta score. Takes precision, recall, and optional beta weight. Returns F1, F-beta, and interpretation of the precision-…

egress-cost-calculator

Use this when a user asks about monthly internet egress cost from daily request volume, average response size, provider, and CDN offload. Uses the same model as the browser calculator.

detect-secrets-scanner

Scan text (config, code, env files) for leaked API keys, tokens, passwords, and private keys, plus static code-risk findings such as dynamic code execution, wildcard CORS, unsafe HTML sinks, process s…

known-vulnerability-checker

Check a package name against a database of known CVEs. Returns vulnerability status, CVE ID, and severity for common packages (log4j, lodash, moment, axios, django, flask, pillow, etc.).

certificate-expiry-checker

Assess certificate expiry risk given a domain and days remaining. Returns risk level (OK, WARNING at <30 days, CRITICAL at <7 days, EXPIRED at <0).

kubernetes-manifest-linter

Lint a Kubernetes manifest (YAML) for common issues: missing resource limits, missing health checks, :latest tag usage, privileged containers. Returns issue list and severity.

dockerfile-linter

Lint a Dockerfile for common issues: :latest tag on FROM, interactive installs without -y, running as root. Returns issues with suggestions per instruction.

query-cost-estimator

Estimate PostgreSQL sequential-scan and index-scan cost from table rows, table pages, selectivity, and storage type. Uses the same four-input model as the browser calculator.

canonical-url-auditor

Audit a page URL against its canonical tag. Detects missing canonical, self-referencing canonical, and relative URL issues.

rate-limit-utilization-calculator

Calculate API rate limit utilization given current request count and limit. Returns utilization percentage, buffer, safety status, and risk level (OK at <80%, WARNING at 80-95%, CRITICAL at >95%).

alert-fatigue-calculator

Use when a user asks about alert noise, alert fatigue, or on-call burden from non-actionable alerts. Given weekly alert volume, actionable %, engineer count, and avg resolution time, returns noise rat…

change-failure-rate-calculator

Use when a user asks about change failure rate or DORA CFR. Given total and failed deployments, returns failure rate percentage and DORA tier.

cloud-waste-calculator
