What problem does it solve? Pstack skills delegate work to subagents across different Claude model tiers, but the default role-to-model mapping may not match the models your account actually has. This Skill detects your available models and writes a single override file so every pstack skill uses models you can actually run. ## Core Features & Use Cases - Model Detection: Probes candidate model slugs (haiku, sonnet, opus, fable) via test subagents or user confirmation, never writing an unverified slug. - Override File Generation: Writes ~/.claude/pstack-models.md with one line per role and imports it into every session via ~/.claude/CLAUDE.md. - Validation and Idempotency: Rejects unavailable slugs, supports inherit-parent and auto aliases, and re-runs cleanly by overwriting the whole file. - Use Case: After installing pstack, run the setup to map roles like critics, arena runners, and swarm workers to the Claude tiers your account exposes, so multi-agent workflows never fail on an unavailable model. ## Quick Start Ask the assistant to run /setup-pstack to detect your available models and configure pstack's model assignments.
