Vesper Compass 3 - Instant Token Cost Estimator
================================================

A production-grade CLI tool to estimate token counts and operational costs
for LLM prompts across multiple files. Built for efficiency and precision.

Features:
- Recursive directory scanning for .txt, .md, .json.
- Robust heuristic tokenization (GPT-2 style regex approximation) for zero-config usage.
- Optional exact tokenization via OpenAI API if API key is provided.
- Real-time cost calculation for major models (GPT-4o, Claude 3.5, etc.).
- Live watch mode for iterative prompt engineering.
- Multi-format output (Markdown table, JSON, CSV).

Usage Examples:
    # Basic estimation for a directory using GPT-4o pricing
    python prompt_cost_analyzer.py ./prompts/ --model gpt-4o

    # Watch a file for changes and calculate costs for Claude 3 Sonnet
    python prompt_cost_analyzer.py prompt.txt --model claude-3-5-sonnet-20240620 --watch

    # Export results to JSON with API key verification for exact counts
    export OPENAI_API_KEY="sk-..."
