Couchbase sizing & capacity planning

A skill for numerical planning of Couchbase deployments. Companion to couchbase-mcp (which operates clusters) and couchbase-data-modeling (which designs the data shape) — this skill answers "how much" and "how many."

When this skill applies

Use this skill whenever the conversation involves estimating resources or capacity:

• "How much RAM do I need?"
• "How many nodes for X documents?"
• "Which Capella tier should I use?"
• "Will this fit in 32 GB?"
• "Should I scale up or scale out?"
• "How big will the index be?"
• "What replica count?"
• "Sizing for vector search"
• "How much XDCR bandwidth"
• "Capacity for next year's growth"
