Why It Matters

For platform engineers and AI agent builders, this quantifies a hidden tax on context windows from bloated skill/agent descriptions, directly impacting effective context budget for actual work in LLM-powered coding assistants.

Key Takeaways

Audit your Claude Code config descriptions with the provided script and prune or compress the heaviest ones to reclaim context window capacity.

My Claude Code config costs 9,857 tokens before I type anything

Summary

A developer measured that their Claude Code configuration of 107 skills, 38 agents, and 15 commands consumes 9,857 tokens (5% of a 200k context window) before any input, because every skill's description loads into context permanently as 'rent' rather than on-demand. The heaviest descriptions, like loop-design-check (244 tokens) and token-budget-advisor (209 tokens), contribute disproportionately to this fixed overhead. The author provides a Python script using character-count token estimation (chars/4) to audit any Claude Code config's description token cost.
