What problem does it solve? It removes the guesswork of choosing which model each pstack role should run on by detecting your available models and recording validated per-role overrides in a single configuration file. ## Core Features & Use Cases - Model Detection: Enumerates the model slugs available in the current session so only confirmed models are written. - Role Map Generation: Writes ~/.codex/pstack-models.md with one line per pstack role, supporting single models, panel lists, and the inherit-parent/auto aliases. - Validation and Idempotency: Rejects unavailable slugs before writing and overwrites the whole file so re-runs stay consistent. - Use Case: After gaining access to a new model, run the skill to reassign critics, arena runners, or swarm workers to that model while leaving other roles on their defaults. ## Quick Start Ask the assistant to run $setup-pstack to detect your available models and configure which model each pstack role uses.
