Draft Shells

Decompose a specification file into shells at .turbo/shells/<spec-slug>-NN-<title>.md. Each shell represents one unit of work for a separate Claude Code session.

Task Tracking

At the start, use TaskCreate to create a task for each step:

Determine which spec to decompose using these rules in order:
