Every PR, priced: AI session costs on your pull requests

The ShellTime GitHub App comments on pull requests your Claude Code or Codex sessions open: their cost, tokens, time, models and an AI summary.

October 10, 20264 min read

Coding agents open a lot of pull requests now. The diff shows what changed, but not what it took to get there: how long the agent ran, which models it used, and what the session would have cost.

ShellTime now puts that right next to the code. When a Claude Code or Codex session on your machine opens a pull request, the ShellTime GitHub App comments on it with the session's cost, tokens, time and models, plus an AI summary of what happened, and keeps the numbers up to date. It's free, and once the app is installed there's nothing to do per pull request.

What you'll see on the pull request

A couple of minutes after your agent opens the pull request, shelltime[bot] comments on it. This is the real comment from one of our own pull requests:
