Conciseness

The body is dense with genuinely non-obvious, project-specific facts (the authoritative marker regex, rect semantics on the 1920x1080 canvas, reverse-line-order rationale) and wastes few tokens on general knowledge. A few sentences could still be trimmed — e.g. the 'shouldn't happen — the inspector won't write one' aside and slight overlap between step 5's marker-removal caveats and step 6's verification — so it sits just below the lean-every-token-earns-its-place anchor.

Actionability

It provides a copy-paste-ready detection regex ('use exactly this'), an executable base64url decode helper, and concrete commands and tools for each step (Edit tool, node -e, /s/<id>/preview?p=N, package-manager typecheck/lint). The guidance is fully executable and covers the common cases (element targets, dragged rects, stacked markers), with no gaps found.

Workflow Clarity

The 7-step procedure is clearly sequenced with an explicit verification step (re-read for leftover markers, typecheck/lint, screenshot) and a feedback loop ('Fix any errors you introduced'), plus a dedicated edge-cases section with skip/report rules. Since this is a batch, partially destructive operation, the present validation loop satisfies the cap and matches the top anchor.

Progressive Disclosure

There are no bundle files; the single SKILL.md is well-organized into Marker format / Procedure / helper / Edge cases / Do not, and it delegates slide-structure detail to the clearly signaled slide-authoring skill one level deep rather than duplicating it. Nothing that belongs in a separate file is inlined, so navigation is easy and structure is appropriate.

Specificity

The description names its domain ('@slide-comment markers written by the open-slide inspector tool') and one concrete action ('Apply pending @slide-comment markers'), matching the 1-2-concrete-actions anchor. It does not list several specific actions, so it falls below the score-4 anchor; the decode/edit/delete-marker sub-steps exist only in the body.

Completeness

It explicitly answers both what ('Apply pending @slide-comment markers written by the open-slide inspector tool') and when (a 'Use when...' clause with multiple quoted trigger phrases), matching the top anchor. The 'when' is already maximally explicit with concrete trigger phrases, so 4 does not fit.

Trigger Term Quality

It quotes several natural user phrases ('apply comments', 'process slide comments', 'apply the inspector comments') and adds a concrete file-path trigger ('references markers left inside slides/<id>/index.tsx'), giving good coverage. It misses common phrasings like 'resolve the comments', 'review the comments', or 'clear the markers', so it is not comprehensive enough for a 5.

Distinctiveness Conflict Risk

The triggers are tightly scoped to slide-comment markers, the inspector tool, and slides/<id>/index.tsx — a clear niche with minimal overlap risk against generic editing or presentation skills. Even the related slide-authoring skill would not be wrongly triggered by these phrases.
