Utility Matrix

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).

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

Use when a user asks about cloud waste, idle resources, or unattached storage. Given monthly cloud bill and idle/oversized percentages, returns waste estimate and tier.

Use this when a user asks whether their Kubernetes cluster has enough capacity, or how many more pods they can schedule. Takes node count (`nodes`), CPU cores per node (`node_cpu`), memory per node in GB (`node_memory_gb`), pod count (`pods`), and resource requests. Returns cluster utilization and headroom.

Use this when a user asks how many database connections to configure in their connection pool, or is troubleshooting PostgreSQL connection exhaustion. Takes CPU cores, app instances, and max_connections. Returns recommended pool size per instance with utilization ratio.

Use when a user asks about deployment frequency or DORA deploy cadence.

Scan text (config, code, env files) for leaked API keys, tokens, passwords, and private keys. Returns findings with redacted matches and severity classification.

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

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, and restore time. Returns Elite/High/Medium/Low tier classification per metric.

Use when a user asks about EC2 cost. Given instance type and hours, returns monthly cost and DO-equivalent savings estimate.

Use this when a user asks how much AWS data transfer or egress costs, or wants to estimate their monthly data transfer bill. Takes monthly transfer volume in GB. Returns estimated monthly egress cost using AWS tiered pricing.

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 budget / Elevated / ALERTING).

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.

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.).

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

Use when a user asks about MTTR or DORA recovery time. Takes incident timestamps (string lines "start,detected,resolved" or array of {start,detected,resolved}).

Use when a user asks about on-call load or burnout risk.

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. Returns monthly billing cost with runner multiplier breakdown.

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-recall tradeoff.

Estimate the relative cost of a SQL query based on heuristic analysis: SELECT *, JOIN count, missing WHERE/LIMIT, leading wildcards, unbounded sorts. Returns cost score and level.

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%).

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 month and net savings over 1yr and 3yr terms.

Use when a user asks about instance rightsizing or overprovisioned compute.

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 and total requests over a period, returns burn rate multiple and time-to-exhaustion signal.

Use when a user asks about risk of a software purchase or SaaS commitment.

Use when a user asks to estimate monthly cost of a Terraform plan.

Use when a user asks about TCO or multi-year SaaS cost.
