⚠️ CRITICAL: Agent Instructions

If the user asked you to load this skill, you MUST use it for token cost computation.

1. ALWAYS use the Rust binaries - they are ultra-fast and purpose-built for this task
2. NEVER write custom Python to parse tokens - the Rust tool already does this
3. If you think you need Python, STOP and ask the user first - 99% of the time the answer is NO
4. These binaries are PIPE-ONLY - they read from stdin, not files directly

⚠️ NEVER RUN STANDALONE - WILL HANG!

# WRONG - will hang waiting for stdin forever!
