When an AI Agent builds a dashboard summary or writes a financial report, it shouldn't guess how to format 10000 as $10,000.00 or 2560000 as 2.5MB. LLMs frequently hallucinate locale-specific separators, currency symbols, and decimal precision.

The Superpowers

  • Pixel-Perfect Formatting: Uses Numeral.js (6M+ weekly downloads) for strict, deterministic number display.
  • Every Format Covered: Currencies ($0,0.00), bytes (0.0b), percentages (0%), abbreviations (0.0a), and custom patterns.
