tool:k8s
Right-size Kubernetes pod CPU/memory requests from real Prometheus usage data (per-pod p95 CPU, p98 memory over 7 days), compute how many nodes the cluster needs, and tune KEDA queue-based autoscaling. Use when the user asks to rightsize workloads, fix over/under-provisioned requests, cut node count or cloud cost, size Celery or background workers, tune KEDA listLength or HPA settings, or answer "how many nodes do we need". Works for any namespace with kube-prometheus and cAdvisor metrics.

From the source SKILL.md

Right-size CPU/memory requests for workloads in a namespace using real 7-day usage from Prometheus, then compute how many nodes the cluster needs. Built for queue-worker fleets (Celery and similar) plus web/API pods, but works for any namespace.

What this skill does

K8s Rightsize is a community-contributed Claude Code skill in the devops sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/k8s-rightsize/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user asks to rightsize workloads, fix over/under-provisioned requests, cut node count or cloud cost, size Celery or background workers, tune KEDA listLength or HPA settings, or answer "how many nodes do we need". Works for any namespace with kube-prometheus and cAdvisor metrics.

Who uses this skill

The K8s Rightsize Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 184,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
