Assesses whether a CSM's portfolio is manageable by computing the weighted workload across all accounts. Raw account count is a poor measure of capacity -- a CSM with 30 enterprise at-risk accounts is more loaded than a CSM with 80 healthy SMB accounts. This skill computes the actual demand.
Capacity Calculator is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/capacity-calculator/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to assess workload, evaluate book capacity, determine if a CSM is overloaded, justify additional headcount, plan account distribution, or when a CSM or manager needs to understand whether the portfolio is sustainable. Also triggers for questions about CSM capacity, workload management, account-to-CSM ratios, book balance, portfolio sizing, or when to hire.
The Capacity Calculator Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 70,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
