capacity-estimation skillA

capacity-estimation is agent-read markdown (skill) from aethrox/doctrine: Turn a vague performance requirement into arithmetic before the architecture is chosen, size concurrency with Little's Law, and label every input as measured, derived, or assumed. Use when a design calls itself "scalable" or "fast" without a number, when choosing between one machine and a distributed system, when sizing a thread pool, connection pool, queue, or instance count, or when someone asks how much traffic, storage, or bandwidth a system will need..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add aethrox/doctrine/capacity-estimation@git:20260910.79ff911
Exact content
mdr add aethrox/doctrine/capacity-estimation@sha256:b66c7afbccd03065

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
