Get Pi Cost

Use this skill when the user asks about Pi session costs, spending, or token usage.

Usage

Run the Python script at pi-cost.py (resolve relative to this skill directory):

# Today's costs
python3 <skill-dir>/pi-cost.py today

# Yesterday's costs
python3 <skill-dir>/pi-cost.py yesterday

# Specific date
python3 <skill-dir>/pi-cost.py 2026-04-03

# JSON output for programmatic use
python3 <skill-dir>/pi-cost.py today --json

The script reads session files from ~/.pi/agent/sessions/ and reports:

• Cost by model — with input, output, and cache-read token counts
• Cost by project — derived from the session directory name
• Top sessions — the 10 most expensive sessions that day
