21 principles · 17 playbooks · 19 skills
Engineering skills that turn a coding agent into a careful crew. You describe a task, and pstack matches it to a playbook.
Type /poteto-mode and describe a task. pstack matches it to a playbook and runs the skills as the steps fire. Twenty-one principles apply across every playbook, biasing the work toward small diffs and real verification.
This is the whole idea behind /poteto-mode. Type a task, or tap an example, and watch the matching playbook light up below.
/poteto-mode → match a playbook → skills fire as steps → clean reply
A playbook is a step-by-step recipe for one kind of task. There are seventeen. /poteto-mode copies the matched one in full before any work starts.
Skills are the individual moves. Reach for one directly when you want a specific result instead of the full route.
Twenty-one rules in five families. Tap any one to see when it applies and what it says.
pstack can use a different model for each role. Some roles run several models in parallel so the reviews come from different angles.
Run /setup-pstack to detect your models and write the rule. Skills read it and fall back to their own defaults when a line is missing, so you override only what you want.
