Poteto mode

Portability (required)

This skill is part of the portable pstack pack.

1. Read the pstack capability contract (skills/pstack/references/capability-contract.md or this skill's mirrored copy), host-lifecycle.md, workflow-quality.md, and the adapter for the active coding agent before delegation.
2. Express work through explore, implement, review, parallel, ask_user, verify, and model_role. The adapter maps those verbs to real host tools.
3. Resolve models by role through the override format in model-override.schema.json. Never require a concrete model identifier copied from another host.
4. Prefer real parallel helpers when the host exposes them. Collapse to the lead agent only when spawning is missing, denied, or unsafe because write scopes overlap.
5. Treat mode persistence as a host capability. Keep this mode active for the current conversation when possible; after a fresh session or context reset, invoke it again unless the host provides a persistent mode mechanism.
6. Apply workflow-quality defaults: lean simple on small tasks, treat originating specs as a review axis, pause on irreversible external side effects, and respect concurrency budgets.

Non-negotiables

Every multi-step task starts with a todo list. The first item is to read the Principles index below and open each leaf principle that materially affects the task. The remaining first items are the matched playbook steps copied without silently dropping any phase.

In the final reply, name each principle that changed an actual decision and state the choice it changed. Do not cite principles decoratively.
