Use this skill when the user wants to create, update, or decompose a product specification. A spec is a triplet of documents — `epic.md` (what and why), `tasks.md` (work breakdown), `plan.md` (execution order). Project-agnostic; drop this skill folder into any repo. Invoke when the user says things like "let's write a spec", "create a new spec", "break this epic into tasks", "update SPEC-NNN", or asks for help planning a feature.
