Conciseness

The body is mostly tight (tables, terse rules, compact snippets), but several rules are stated verbatim twice — the runtime-only easing/repeat/direction ban appears in "Preview-only boundary" and again in "Hard rules", the no-manual-hidden-state rule appears in "Hard rules" and again in "Failure repair strategy", and the stagger and "with" patterns each get duplicated old/new-syntax example pairs. This matches "mostly efficient but includes some unnecessary explanation or could be tightened"; not 4 because the duplication is systematic rather than a couple of trimmable lines.

Actionability

Guidance is fully executable: complete copy-paste HTML snippets for every trigger pattern, an exhaustive supported-types list, a full attribute table with value domains, a concrete `PPT.animate(targets, params)` example, and a directional-examples block. The repair strategy gives exact checks ("replace `anime(...)` with `PPT.animate(...)`"), matching "copy-paste ready ... specific examples cover the common cases".

Workflow Clarity

The "30-second decision checklist" gives an explicit pre-work sequence (reading path → trigger → type → duration) and the "Failure repair strategy" is a numbered 1-4 diagnostic loop with concrete fixes, which is a genuine feedback loop. Not 5 because the add-animation path has no verification step (e.g., confirm the animation plays in preview before considering the slide done); not 3 because checkpoints are explicit in both the checklist and repair sections.

Progressive Disclosure

The pointer to `references/data-anim.md` is clear and well-signaled at the top, but the bundle also contains `references/animation-prompt-cookbook.md` (~15KB of per-type prompt recipes) which is never mentioned in SKILL.md, making it undiscoverable; additionally the inline supported-types list overlaps the mapping table already in the reference. This matches "some structure but could be better organized"; not 4 because an entire bundle file being orphaned from the index is more than a minor gap.

Specificity

"Defines exportable data-anim usage, trigger decisions, and how to replace unsupported scripted/anime.js animation" names the domain and three concrete functional areas, matching the anchor for several specific actions with minor gaps. Not 5 because "Defines ... usage" describes documentation content rather than comprehensively stating capabilities; not 3 because it goes beyond 1-2 actions.

Completeness

"Must be read before adding or modifying Oh My PPT slide animations" is explicit trigger guidance (equivalent to a 'Use when' clause), and the "Defines exportable data-anim usage..." clause states what it does. Not 5 because the when-clause lacks concrete trigger phrases (e.g., "use when the user asks for staggered reveals"); not 3 because both what and when are explicitly present.

Trigger Term Quality

"Oh My PPT slide animations", "data-anim", and "anime.js animation" are relevant keywords, but common natural phrasings users would say — "entrance/emphasis effects", "motion", "transitions", "staggered reveal" — are absent. Matches "some relevant keywords but missing common variations"; not 4 because the natural-term coverage beyond the word "animation" is thin.

Distinctiveness Conflict Risk

"Oh My PPT slide animations" with the specific "data-anim" contract carves out a clear niche with distinct triggers and minimal conflict risk against generic skills. The tool-specific scope makes triggering for the wrong skill unlikely.
