Lauren Tan just published part 1 of a written guide to pstack. This is not the Maven recording. This is how she actually uses it.
Part 1 is verification. The agent has to check its own work so you are not the bottleneck. She treats that skill like infrastructure. Install pstack, run /create-verification-skill, and give the agent a small CLI it can drive, not just markdown.
She has been doing this as the gardener on Grok Bot while the team lands hundreds of PRs a day. Volume only matters if the quality holds.
