pi-cost

A utility skill to parse and estimate costs for the active Pi coding agent session, including any subagents called during the run.

Setup

The Python helper script is pre-installed in the skill folder: scripts/pi_cost.py

No extra dependencies are required.

Usage

When triggered, execute the helper script using the bash tool:

python3 .claude/skills/pi-cost/scripts/pi_cost.py

This will output:

1. Active session file name and path.
2. Main session stats: total turns, tokens (input/output/cacheRead/cacheWrite), and estimated cost based on standard model pricing.
3. Nested subagent runs: breakdown of subagent name, model, turns, token details, and estimated cost.
4. Total consolidated session summary.
