Watch one library brief run end to end
A coding agent read the 89-word subagents brief, built a read-only code reviewer, and the reviewer reported nine findings it could not edit. The page shows the session log, the files, the time and the cost; the brief is now free.
Download the sample project and the two prompts, run them in your own Claude Code, and compare your log with ours.

The working-check starter states that its Python checker validates handoff structure and declared status. A passing record alone cannot prove the task ran.
Run the negative fixtures and inspect the evidence. Verify hook execution in your own host before relying on it.
