Reads a site feature specification file and converts it into a structured, actionable development task list saved to the project memory bank. Use when you need to break down requirements into developer tasks, plan project work from a PRD or spec, convert feature specifications into tickets with acceptance criteria, or create a task breakdown from site-setup documentation. Produces per-task acceptance criteria, file references, and technical stack notes drawn exclusively from the specification — no scope creep or unspecified features added.
