Conciseness

Nearly every token earns its place: complete package.json, Makefile, slides.md template, layout lists, colour-token table, and keyboard-shortcut table are all actionable, not filler. Minor trimmable spots keep it below 5 - e.g., the editorializing in 'if they then scroll past some styling, so be it' and the keyboard edit/save section repeating the table's content in prose ('Press E, edit text inline, Cmd+S to download the updated HTML').

Actionability

Fully executable, copy-paste-ready guidance: complete 'package.json' and 'Makefile' blocks, a starter slides.md template, exact commands ('make dev serves presentation.html on http://localhost:2663'), precise markup conventions ('<section class="slide <type>" data-name="<unique-id>>'), and concrete colour hex tokens. Specific examples cover the common cases for both modes.

Workflow Clarity

Both modes have clearly sequenced numbered setup flows with concrete commands and preview feedback ('Suggest make slides to preview changes'), matching the 'clear sequence with most checkpoints' anchor. It is below score 5 because validation checkpoints are largely absent - e.g., no verify step after scaffolding, after regenerating notes.html, or after the gh-pages deploy ('Each pushes a single commit') - and above score 3 because the sequences themselves are specific and complete rather than merely listed.

Progressive Disclosure

Reference links are well-signaled and one level deep, and all four resolve ('references/qblabs-example-slide.html', 'references/dwmkerr-com-timeline-slide.html', 'references/conference-example.html', 'references/dwmkerr-com-timeline-slide.png'). However, scoring against the actual bundle, the core paths 'themes/conference/template/' and 'themes/qblabs/' do not exist - conference setup step 2 ('Copy everything under themes/conference/template/ into the target folder verbatim') depends on a missing directory. Additionally, ~150 lines of theme and conference-mode detail are inlined in SKILL.md where they could be separate files, matching the 'some structure; content that should be separate is inline' anchor rather than the 'minor organization gaps' of score 4.

Specificity

The description names the domain ('Create and manage presentation decks') and the two modes ('Slidev markdown (default) and "conference" hand-built HTML'), but the only actions offered are the generic verbs 'create' and 'manage' - no scaffold/generate/deploy-level concrete actions, matching the 'names domain and 1-2 concrete actions' anchor. It is below the score-4 anchor, which requires several specific actions (e.g., scaffolding folders, generating content, deploying to GitHub Pages), and above score 2 because the two named modes keep it from being purely generic.

Completeness

Explicitly answers both questions: the 'what' ('Create and manage presentation decks. Two modes - Slidev markdown (default) and "conference" hand-built HTML') and the 'when' ('Use when user asks to... or mentions...') with concrete trigger phrases. This matches the top anchor exactly; not score 4 because the 'when' clause is fully explicit rather than merely adequate.

Trigger Term Quality

Comprehensive natural trigger phrases including synonyms and project-level variants: '"create slides", "make a presentation", "add slides to this project", "set up a slide deck"' plus '"slidev", "pitch deck", "conference talk", "conference deck", or "slides folder"'. These are exactly the phrases a user would naturally say, matching the comprehensive-coverage anchor.

Distinctiveness Conflict Risk

Clear niche (presentation decks) with distinct, unlikely-to-collide triggers such as '"slidev"', '"pitch deck"', and '"conference talk"'. Minimal overlap risk with other skills, matching the 'clear niche with distinct triggers' anchor.
