Verification skill: reproducible agent control

Lauren's first pstack guide treats a verification skill as shared engineering infrastructure: an agent-facing CLI plus a maintained feature map that lets agents exercise and inspect an application. Why it matters: More agents only increase useful throughput when they can test their own changes and return evidence; otherwise review becomes the bottleneck.

Try this: Run one representative change through a small control CLI, then require a trace, screenshot, or diff as the verification artifact before review.
