Conciseness

The body avoids explaining known concepts and every rule is skill-specific, but it is noticeably repetitive: "actual gaps between independent modules" appears roughly eight times, the 1600×900 canvas is restated in nearly every section, and §1 step 3, §5, and §7 all re-cover over-density summarization with overlapping wording. This matches 'mostly efficient but could be tightened' better than the level-4 anchor, whose over-explanation is only minor.

Actionability

Guidance is fully concrete and executable: exact pixel floors (18px body, 24px headings, 12px auxiliary), specific Tailwind classes (`grid-rows-[auto_1fr_auto]`, `min-w-0`, `gap-4`), chart height ranges (380–560/280–360/220–280px), the required marker `@ppt-chart-height=N`, and a named pattern lookup table. Per the rubric's scoring note, absence of inline code in an instruction-only skill is not penalized when the guidance is this actionable, so it fits the top anchor.

Workflow Clarity

§1 gives a numbered decision path (0–7) ending in an explicit validation checkpoint — "Before calling the write tool, estimate the final layout... If either dimension exceeds the canvas, redesign the composition and check again" — and §10 provides an ordered failure-repair strategy with a mirror case for under-fill. Combined with the P0/P1/P2 checklist reference, this matches the anchor for clear sequence, explicit validation, feedback loops, and checklists; the operation is also not destructive/batch, so no cap applies.

Progressive Disclosure

The body opens with a clearly signaled, one-level-deep map of the three reference files (all verified to exist in the bundle: catalog.md, layout.md, checklist.md), each with a one-line purpose statement, and points to them inline at the exact sections where they matter. References cross-point sideways (layout.md → catalog.md) rather than nesting downward, matching the top anchor for a clear overview with well-signaled one-level-deep references.

Specificity

The description enumerates six concrete capabilities — "the per-page decision path, the named layout pattern catalog, canvas budgeting, collision avoidance, chart overpack guardrails, and title readability rules" — which comprehensively covers the skill's actual scope. It matches the anchor for multiple specific concrete items with comprehensive coverage, and is not the level below because the actions are not merely 'several with gaps' but a full inventory of what the body delivers.

Completeness

"Must be read before creating, relaying out, or repairing Oh My PPT slide layouts" explicitly answers 'when' with concrete trigger phrases (an equivalent of a 'Use when...' clause), and "Defines the per-page decision path..." explicitly answers 'what'. Both halves are concrete, so it clearly fits the top anchor rather than the level-4 anchor where the 'when' is present but could be more explicit.

Trigger Term Quality

Natural trigger terms are present — "creating", "relaying out", "repairing", "slide layouts", "PPT" — phrasing a user would plausibly say. It is not a 5 because common synonyms like "presentation", "slide deck", "slide design", or "overflow" are missing, matching the anchor for good keyword coverage with a few natural terms absent.

Distinctiveness Conflict Risk

"Oh My PPT slide layouts" carves out a clear niche tied to a specific tool family and layout concern, so it is mostly distinct. It is not a 5 because the skill suite contains closely related siblings (style, chart, animation skills referenced in §11), and layout-adjacent terms could pull triggers for those — matching the anchor for minor overlap risk with closely related skills.
