Model technical capacity, unit cost, and budget constraints connected to demand, performance, and reliability decisions. Use when projecting capacity from growth forecasts, sizing for peak events, designing cost-aware scaling policies, defining budget thresholds or quota/rate-limit enforcement, running or planning load/soak tests as capacity evidence, resolving SLO-cost tradeoffs, or modeling multi-tenant demand distributions, hot-tenant skew, pooled or siloed headroom, fairness evidence, and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Capacity and Cost Engineering Connect demand, performance, reliability, and spend into defensible capacity and cost decisions. This skill models technical capacity, calculates unit cost at the infrastructure level, defines budget and quota controls, requires load/soak evidence for capacity claims, and makes cost-performance tradeoffs explicit — producing evidence that feeds [production-readiness](../production-readiness/SKILL.md) launch decisions and constrains or supports [site-reliability-engineering](../site-reliability-engineering/SKILL.md) SLO choices. ## Connected dimensions Demand (traffic and growth), performance (latency and throughput), reliability (SLOs and error budgets), and spend (cost) are treated as **connected dimensions** — a change in any one dimension affects the others. The skill's core method is tracing the connection: | Dimension | Capacity impact | Cost impact | |-----------|----------------|-------------| | Demand (traffic, growth rate) | Drives compute, storage, network requirements | Drives baseline and projected spend | | Performance (latency, throughput target) | Constrains resource headroom per request | Tighter targets increase unit cost | …

How to install
mdr add magnus919/agent-skills/capacity-and-cost-engineering@sha256:1fad42b0c4f9f27bThe line at the top of this page pins the label git:20261103.4f03205, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
