The body is mostly efficient structured tables and copy-paste templates, but the Scrum Guide definition is quoted twice (Overview and Per-organization sections) and the lightweight Review cadence / Anti-patterns sections pad slightly, so it could be tightened.

It provides fully copy-paste-ready artifacts — a complete starter DoD markdown block and a full PR template — with concrete gates (`smoke-suite-gate`, coverage ≥80%, axe/pa11y/Lighthouse), matching the 'fully executable, copy-paste ready' anchor.

As a single-purpose reference/checklist skill with no destructive multi-step operation, its maintenance process (DoD evolution, review cadence, anti-patterns with fixes) is unambiguous and clearly sequenced, satisfying the simple-skill allowance.

It is a single well-organized SKILL.md with clear section headers and no nested references; the only pointers are one-level (the Scrum Guide URL and `smoke-suite-gate`), and the inline templates are appropriately the core deliverable rather than separate-file material.

The description lists multiple concrete actions ('explains the Scrum Guide's DoD definition', 'proposes a starter DoD with the 7-10 lines', 'emits a per-PR checklist a reviewer enforces') with an enumerated set of specific DoD lines, matching the 'lists multiple specific concrete actions' anchor.

It explicitly answers both what the skill does and when to use it via the 'Use when the team doesn't have a DoD or wants to revise theirs' trigger clause, satisfying the 'clearly answers both what AND when' anchor.

It covers natural terms a user would say — 'Definition of Done', 'DoD', 'team doesn't have a DoD', 'revise theirs' — giving good coverage of the phrases teams actually use.

'Definition of Done (DoD)' is a clearly distinct niche with specific triggers unlikely to overlap with unrelated skills, matching the 'clear niche with distinct triggers' anchor.
