Setup pstack

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

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

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

On GitHub Copilot, follow the Copilot setup in place of steps 1, 3, 4, and 7 and step 6's header.

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. The Claude Code config directory is $CLAUDE_CONFIG_DIR when that variable is set and ~/.claude otherwise. This skill calls it <config>. Inclusion is explicit: the user adds a line to <config>/CLAUDE.md (or their project CLAUDE.md) such as:

@<config>/pstack-models.md
