Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description carries the full burden. It compensates well: title is marked as required, description is explained as a one-line goal, and project_rules is given concrete meaning as markdown covering stack/conventions/tone inherited by tasks. It does not elaborate on nullability or format constraints, but the schema already displays defaults.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
