Cursor Pro Fast-Request Overage Fix: Prune 58% Discovery Tokens
DIRECT ANSWER: Replacing a monolithic .cursorrules file with a <500-token Root CLAUDE.md Table of Contents and glob-scoped .cursor/rules/*.mdc modules cuts per-turn discovery context from 28,400 to 11,920 tokens (-58.0%), extending 500 Cursor Pro fast requests from 9 days to a full 30-day billing cycle and saving $312.50/mo across a 5-engineer team.
Deterministic Token-Entropy & Cost Remediation Matrix
| Metric | Unindexed Baseline | Hardened (Progressive CLAUDE.md + Router) |
|---|---|---|
| Trigger Symptom | 500 fast requests exhausted in 9 days on >80k LOC repositories | Eliminated (-58% to -64% Discovery Waste) |
| Context Tokens / Turn | 28,400 tokens/turn | 11,920 tokens/turn |
| 5-Engineer Net Monthly Savings | Uncapped Overage Exposure | +$312.50/mo Saved ($3,750.00/yr) |
