spec-structure

The 4-file spec structure (1-description, 2-analysis, 3-solution, 4-status): what belongs in each file, the required sections, and the Tracking info fields. Use when: creating, analyzing, reviewing, implementing or archiving a spec; deciding which of the four files a piece of content belongs in. Do NOT use for: general documentation formatting (use the documentation skill), the workflow around the files (use the workflows skill).
