Conciseness

The body is mostly lean and well-organized with bullet points and a numbered workflow, assuming Claude's competence; a few 'What is covered' bullets restate constraints already captured in the Constraints and Workflow sections and could be trimmed.

Actionability

It gives concrete, specific guidance (3-6 layers, 4-5 options ordered simplest to richest, the smallest-useful-version question) and names the routing skills, though it relies on a reference file for the worked mechanics rather than including inline examples.

Workflow Clarity

A clear six-step sequence with explicit self-check checkpoints ('value, size, testability, deliverability, and issue-tracking suitability') and a feedback-style scope-challenge step before composing the first slice.

Progressive Disclosure

The SKILL.md is a concise overview with a single, clearly signaled one-level-deep reference (references/052-design-hamburger-method.md) that exists in the bundle, and routing links to sibling skills are explicit and navigable.

Specificity

The description lists several concrete actions (split into vertical slices, find smallest useful slice, break feature into slices) tied to a named method, though coverage is more about triggering than enumerating the method's full mechanics.

Completeness

It explicitly answers both 'what' (split oversized work into small vertical slices via the Hamburger Method) and 'when' (with a clear 'Use when...' clause and concrete trigger phrases).

Trigger Term Quality

It embeds a comprehensive set of natural trigger phrases users would actually say ('Split this oversized story', 'Find the smallest useful slice', 'Apply the Hamburger Method'), giving strong keyword coverage with synonyms.

Distinctiveness Conflict Risk

The Hamburger Method framing is a fairly distinct niche with specific triggers, but the broad 'large feature, story, plan, or spec' language could overlap with general planning/slicing skills.
