The body avoids concept over-explanation and delegates detail to a reference file, but the 'What is covered in this Skill?' list restates the workflow and 'When to use' duplicates the frontmatter triggers, so it could be tightened.

Provides concrete, quantified guidance ('Identify 3-6 functional or workflow layers', 'generate 4-5 implementation or quality options ordered from the simplest acceptable choice to richer choices') plus explicit MUST/MUST NOT constraints, which is fully actionable for an instruction-only skill.

A clear 6-step sequenced workflow culminates in an explicit self-check checklist (value, size, testability, deliverability, issue-tracking suitability); no error-recovery loop is required for a low-risk planning skill per the scoring notes.

The body is an overview that points to a single, clearly signaled, one-level-deep reference (references/052-design-hamburger-method.md, which exists) with well-organized sections, matching the clear-navigation anchor.

Lists multiple concrete actions such as 'split into small vertical slices', 'Find the smallest useful slice', and 'Break this feature into vertical slices', matching the comprehensive-actions anchor rather than the partial score-2 anchor.

Explicitly states what the skill does ('split into small vertical slices with the Hamburger Method') and when to use it ('Use when a large feature, story, plan, or spec idea needs to be split' plus a trigger list), satisfying both what and when.

Includes natural user phrasings verbatim ('Split this oversized story', 'Apply the Hamburger Method', 'Turn this broad plan into tracked slices'), giving good coverage of terms users would actually say.

The named 'Hamburger Method' gives a niche, but generic triggers like 'Split this oversized story' and 'Find the smallest useful slice' overlap with the toolkit's other planning skills, so it could still trigger the wrong skill.
