Setup pstack

On Codex, read the platform mapping, including its per-skill notes, before following this skill.

On another runtime, read Other runtimes below for where the sheet lives and how it loads; the steps are the same.

Write the current runtime's per-role model override sheet, using the path in Other runtimes. Each pstack skill names a default model inline; the override sheet adapts those defaults to the models you actually have access to.

Claude Code has no auto-applied "rules" mechanism like Cursor's .mdc. Inclusion is explicit: the user adds a line to ~/.claude/CLAUDE.md (or their project CLAUDE.md) such as:

@~/.claude/pstack-models.md

so the file is loaded as context for every session.

1. Detect available models
