Conciseness

Two lean sentences with zero padding — every token earns its place and nothing explains what Claude already knows. This matches the "lean and efficient; assumes Claude's competence" anchor exactly.

Actionability

The guidance is concrete for an instruction-only skill: "Go up a layer of abstraction. Give me a map of all the relevant modules and callers, using the project's domain glossary vocabulary" specifies an exact deliverable. It falls short of fully executable only because it assumes a domain glossary exists without offering a fallback.

Workflow Clarity

This is a simple, single-purpose skill (a single prompt with one unambiguous action), which the scoring notes say can score 5 when the action is unambiguous. No destructive or batch operations are involved, so no validation cap applies.

Progressive Disclosure

The skill is under 50 lines with no need for external references — a two-sentence prompt has nothing to split or disclose progressively, and no bundle files exist to reference. This fits the simple-skill exception for a clean top score.

Specificity

The description names the domain (code comprehension) but the actions are generic — "zoom out and give broader context or a higher-level perspective" names no concrete deliverable (the concrete "map of modules and callers" guidance lives only in the body). The second-person clause "Use when you're unfamiliar" further costs 1 point per the voice guideline.

Completeness

Both parts are present: a what ("Tell the agent to zoom out and give broader context or a higher-level perspective") and an explicit "Use when you're unfamiliar with a section of code or need to understand how it fits into the bigger picture" clause. The what is explicit but not fully concrete, so it sits between the 4 and 5 anchors.

Trigger Term Quality

Natural trigger phrases are present — "zoom out", "broader context", "higher-level perspective", "unfamiliar with a section of code", "bigger picture" — giving good keyword coverage, though a few natural synonyms ("overview", "architecture", "how does this fit together") are missing.

Distinctiveness Conflict Risk

"Zoom out" / "bigger picture" framing carves a reasonably distinct niche, with only minor overlap risk against closely related skills like code-explanation or architecture-review skills.
