Portability (required)

This skill is part of the portable pstack pack.

1. Read the pstack capability contract and the adapter for the active coding agent before delegation.
2. Use explore for grounding, parallel through arena for competing sketches, implement for bounded code work, review for independent pressure, and verify for the resulting contract.
3. Resolve workers through model_role; never require a vendor-specific model identifier or helper type.
4. Keep implementation write scopes disjoint. When helpers are unavailable, perform the same phases on the lead agent rather than skipping design work.

Goal

Design before implementing. Start with caller usage, derive types and interfaces, compare structurally different solutions, and implement against the selected sketch. When implementation repeatedly fights the design, discard the sketch and redesign instead of adding escape hatches.

Start

Create a todo list with one item per phase:
