121121* **Free runs**: the three Pro and Max runs are a one-time allotment per account and don't refresh.
122122* **Cost per review**: after you use the free runs, typically \$5 to \$25 in usage credits depending on the size of the change, matching the estimate the launch dialog shows before each run.

164164Progress messages and the live session URL go to stderr so stdout stays parseable. Use these flags to control the output, the timeout, and whether to post the findings:
165165
166| Flag | Description |
167| --------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
168| `--json` | Print the raw `bugs.json` payload instead of the formatted findings |
169| `--timeout <minutes>` | Maximum minutes to wait for the review to finish. Defaults to 45 |
170| `--post` | [Post the finished findings](#post-findings-to-the-pull-request) to the pull request as one plain comment from your GitHub account. Works on `github.com` pull request targets; on other targets, Claude Code ignores the flag and says so. Requires Claude Code v2.1.227 or later |
171| `--no-post` | Don't post the findings. This is the default, and if you pass both flags, Claude Code doesn't post. Requires Claude Code v2.1.227 or later |
