Cluster Tuning

Category: Engineering  ·  Sub-category: performance  ·  Last updated:
Use whenever editing the Scala cluster-tuning module under `src/main/scala/com/db/serna/orchestration/cluster_tuning/` — `single/` (the per-date tuner), `auto/` (multi-date AutoTuner), `diff/`, and the loader-side of `log_analytics/`. Triggers when the user mentions the tuner, ClusterMachineAndRecipeTuner, AutoTuner, machine selection, executor sizing, autoscaling policy, cost calculation (b20/b21/b22/b23), PriceCatalog, ClusterSummary, ClusterPlan, RecipeMetrics, GenerationSummary, TuningStrategy / BiasMode / ExecutorTopologyPreset, MachineCatalog, the Csv parser, parseInstant, or any of the `_clusters-*.csv` outputs. Apply even when the user doesn't name the module — if they're modifying a `bNN.csv` loader, debugging an `estimated_cost_eur` value, or adjusting how clusters are scored, this skill applies.

What this skill does

Cluster Tuning is a community-contributed Claude Code skill in the performance sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cluster-tuning/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever editing the Scala cluster-tuning module under `src/main/scala/com/db/serna/orchestration/cluster_tuning/` — `single/` (the per-date tuner), `auto/` (multi-date AutoTuner), `diff/`, and the loader-side of `log_analytics/`. Triggers when the user mentions the tuner, ClusterMachineAndRecipeTuner, AutoTuner, machine selection, executor sizing, autoscaling policy, cost calculation (b20/b21/b22/b23), PriceCatalog, ClusterSummary, ClusterPlan, RecipeMetrics, GenerationSummary, TuningStrategy / BiasMode / ExecutorTopologyPreset, MachineCatalog, the Csv parser, parseInstant, or any of the `_clusters-*.

Who uses this skill

The Cluster Tuning 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 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Cluster Tuning Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/cluster-tuning/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Cluster Tuning skill do?
Use whenever editing the Scala cluster-tuning module under `src/main/scala/com/db/serna/orchestration/cluster_tuning/` — `single/` (the per-date tuner), `auto/` (multi-date AutoTuner), `diff/`, and the loader-side of `log_analytics/`. Triggers when the user mentions the tuner, ClusterMachineAndRecipeTuner, AutoTuner, machine selection, executor sizing, autoscaling policy, cost calculation (b20/b21/b22/b23), PriceCatalog, ClusterSummary, ClusterPlan, RecipeMetrics, GenerationSummary, TuningStrategy / BiasMode / ExecutorTopologyPreset, MachineCatalog, the Csv parser, parseInstant, or any of the `_clusters-*.csv` outputs. Apply even when the user doesn't name the module — if they're modifying a `bNN.csv` loader, debugging an `estimated_cost_eur` value, or adjusting how clusters are scored, this skill applies.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Cluster Tuning skill?
Use Cluster Tuning when your Claude Code task falls under the Engineering category — specifically in the performance area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Cluster Tuning" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Cluster Tuning skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Cluster Tuning is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
