Pick Workflow

Authoring-time judge for a skill/agent's execution topology. Sibling to /pick-model: it picks the model+effort for one step; this picks how steps run (linear vs fan-out, sub-agents vs Workflow, the seam) and calls /pick-model per step for the model. Emits a design — never runs the task.

CLAUDE.md contract: this skill is the single source of truth for the execution-topology call (linear vs fan-out, fresh sub-agent vs fork vs Workflow, the seam). CLAUDE.md "Execution defaults" carries no sub-agent rules — it defers here by capability (auto-discovery on the description). Don't re-derive the mechanism table or sharding rules elsewhere; if topology guidance changes, it changes here.

When: authoring or challenging a skill/agent · deciding parallel-vs-linear · sub-agents-vs-Workflow.

Steps

1. Decompose — fill the table FIRST (it IS the analysis; no recommending before it exists)
