gke-rightsizing-checks SKILL.md skillA
gke-rightsizing-checks from gke-labs/kube-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add gke-labs/kube-agents/gke-rightsizing-checks@git:20261027.675114dPins git:20261027.675114d in mdr.lock. Pin the fingerprint instead.

Five required checks, and the arithmetic, before any proposal to lower a workload's CPU or memory requests or limits, or to change a node pool's machine type or size, and before any claim of capacity freed. Read-only. For "lower the requests of X", "right-size this deployment", "can this pool use a smaller machine type", and any answer that claims nodes, CPU, memory or a percentage freed.
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
# GKE Rightsizing Checks Use this skill before you propose a lower request or limit, a machine type or a node count, and before you claim capacity freed. Raising a limit to stop an OOMKill is a fix, not a rightsizing proposal, and this skill does not apply to it. A request is rarely just a number: an HPA scales on it, a limit may be tied to it, a budget or a claim may share its pods, and the file that declares it may render other clusters too. A proposal that skips those reads looks right and changes something nobody asked to change. The skill is read-only. It produces checks and arithmetic, and a proposal the person applies through the Platform Agent. ## The rule Run all five checks for each workload or pool you propose to change, and show each one in the answer: what you checked, the command, and what it returned. A check you could not run is reported as not run, with the reason, and you propose no number for the dimension it governs. Every effect claim (nodes freed, CPU or memory freed, a percentage, "fits without scale-up") carries its calculation, with the inputs it used. Give no prices: this deployment has no price data, and a dollar figure here is a guess. …

How to install
mdr add gke-labs/kube-agents/gke-rightsizing-checks@sha256:de00a47d714646f4The line at the top of this page pins the label git:20261027.675114d, 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.
