Setup pstack

Before resolving models or delegating, read T3 execution. It defines global configuration, capacity selection, and transport constraints.

Write pstack-models.md, a file that sets pstack's model selection per role. Default to ~/.agents/pstack-models.md; use the project root only for a requested project override. Read model selection for candidate-pool syntax, update behavior and Fleet persistence. Preserve existing choices. For this user's automatic setup, use open capacity and retain the skill's reasoning requirements; do not make them choose a fixed roster to start. Keep existing preferences. Ordinary fallback can use qualifying alternatives without rewriting them; honor actual strict prohibitions.

Steps

1. Detect available models

Call orchestrator_capabilities. It lists the providers and models you can pass to delegate_task in this session, custom models included, with each one's provider instance ID and any reasoning options. That is the only source. Use enabled providers that can run child tasks. If none qualify, report the limitation. Never add a fixed model or pool entry absent from that catalog. inherit-parent and capacity are policies, not model IDs. Read t3-capacity for current account availability, but persist no usage snapshots.
