managing-cluster-capacity

managing-cluster-capacity is a skill for Cursor from cockroachdb/cursor-plugin. It costs 95 tokens per session (3,420 once invoked), scanned A, a copy of managing-cluster-capacity, Apache-2.0.

A guide to changing how much work a CockroachDB cluster can handle. The steps differ between self-hosted clusters, CockroachDB Cloud plans, and serverless deployments.

In plain words
What is it for?
Use it to add, remove, replace, or resize cluster nodes, adjust provisioned computing power, manage storage pressure, or control costs on a serverless cluster.
Why use it?
It helps you add or remove database capacity without confusing permanent node changes with temporary maintenance. It also clarifies how capacity changes affect storage, hardware, and costs.

About the project

CockroachDB Plugin for Cursor connects the Cursor coding agent to CockroachDB clusters for database work such as exploring schemas, writing SQL, debugging queries, and managing distributed clusters. It supports self-hosted and CockroachDB Cloud connections, and its catalogue add-ons provide database-focused agents, skills, rules, and instructions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

managing-cluster-capacity scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Managing Cluster Capacity

Manages cluster capacity across all CockroachDB deployment tiers. What "capacity" means varies by tier — Self-Hosted manages individual nodes, Advanced/BYOC manage node count and machine size, Standard manages provisioned vCPUs, and Basic auto-scales with cost controls.

When to Use This Skill

  • Permanently removing a node from a cluster (Self-Hosted)
  • Adding nodes to increase capacity (Self-Hosted)
  • Scaling cluster node count or machine size (Advanced, BYOC)
  • Adjusting provisioned compute (Standard)
  • Managing costs on a serverless cluster (Basic)
  • Replacing hardware or migrating infrastructure (Self-Hosted, BYOC)
  • Replacing a failed or dead node (Self-Hosted)
  • Managing storage utilization and disk pressure (Self-Hosted)

For temporary maintenance (not capacity changes): Use performing-cluster-maintenance. For pre-operation health check: Use reviewing-cluster-health.

Step 1: Gather Context

Required Context

Question Options Why It Matters
Deployment tier? Self-Hosted, Advanced, BYOC, Standard, Basic Different capacity model per tier
Direction? Scale up (add capacity), Scale down (reduce capacity) Determines procedure

Additional Context (by tier)

If Self-Hosted (scaling down):

Question Options Why It Matters
How many nodes to remove? 1, multiple Multi-node decommission should be done simultaneously
Target node IDs? Node IDs from cockroach node status Required for CLI commands
Is the node alive or dead? Alive, Dead Dead nodes use a different procedure
Deployment platform? Bare metal, VMs, Kubernetes Changes CLI and cleanup steps
Current replication factor? 3, 5, custom Must have enough nodes remaining
Current node count? Number Validates remaining capacity
Storage utilization? Low (<60%), Medium (60-80%), High (>80%) Determines urgency and whether storage maintenance is needed

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
