Conciseness

The body never explains concepts Claude already knows and is information-dense throughout, but it includes avoidable duplication: the resources list appears nearly verbatim in both 'Dependencies' and 'References', the 'Expected outputs' bullets are restated as a YAML outputs block, and inline minutiae like the full MCP config-file path enumeration ("~/.gemini/antigravity-cli/mcp_config.json (agy global)") belong in canva-integration.md. This fits 'mostly efficient but... could be tightened' — not a 4 because the duplication is more than minor trimming, not a 2 because there is no padded explanation or filler prose.

Actionability

The 'Canonical command path' gives copy-paste-ready CLI invocations with real flags (e.g. "oma slide validate --workspace \"$DECK_DIR\" --output json", "oma slide export png --workspace \"$DECK_DIR\" [--resolution 720p|1080p|1440p|2160p|4k]") plus env-var overrides, exact artifact paths, doctor preconditions, and guardrails phrased as concrete rules ("Wrap all CSS animations in @media (prefers-reduced-motion: no-preference)"). This matches 'Fully executable; copy-paste ready code or commands' — not a 4 because there are no missing key details for the common cases.

Workflow Clarity

The Structural Flow gives a clear Entry sequence, explicit Transitions, an enumerated 'Failure and recovery' section, and defined Exit criteria, with an explicit validation feedback loop: "Validate (after writing slides)" → "max 3 auto-fix iterations, then surfaces diff to user" plus a referenced pre-delivery checklist. This matches 'Clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes' — not a 4 because validation checkpoints are explicit at every stage rather than having minor gaps.

Progressive Disclosure

The body is an overview that defers detail to one-level-deep, well-signaled references: a References section maps each resources/*.md file to its purpose ("Stage rules + embed instructions: resources/fixed-stage.md", "Pre-delivery gate: resources/checklist.md"), and no reference chains deeper than one level. Not a 5 because the reference list is duplicated from Dependencies (weaker navigation), and some content that belongs in the referenced files — the MCP config path enumeration and the 16-item guardrails list — is inlined in SKILL.md; not a 3 because references are clearly signaled and the split is otherwise appropriate.

Specificity

The description lists several concrete actions — "Create, import, revise, or export presentation decks through the OMA slide CLI" — plus concrete output formats ("HTML slides and PDF, PNG, or PPTX"), matching the anchor 'Lists several specific actions; minor gaps in coverage'. Not a 5 because real capabilities from the body (Canva import/export, style presets, importing .pptx files) are omitted from the action list; not a 3 because four distinct verbs plus named formats go beyond '1-2 concrete actions'.

Completeness

Both parts are present: the 'what' is explicit ("Create, import, revise, or export presentation decks through the OMA slide CLI") and the 'when' uses an explicit trigger clause ("Use for HTML slides and PDF, PNG, or PPTX deck delivery"), so the missing-'Use when' cap of 3 does not apply. Not a 5 because the 'when' clause is format-focused rather than scenario-oriented — it lacks concrete user-scenario triggers like 'when the user asks to create a presentation or mentions slides/decks'; not a 3 because the 'when' is explicit, not merely implied.

Trigger Term Quality

It includes natural terms users would say — "presentation decks", "HTML slides", "PDF, PNG, or PPTX", "deck delivery" — giving good keyword coverage with a few natural terms missing. Not a 5 because common synonyms like "PowerPoint", "keynote", "slide show", and the file extension ".pptx" are absent; not a 3 because coverage goes well beyond 'some relevant keywords' with multiple natural phrasings and format names.

Distinctiveness Conflict Risk

The pairing of "OMA slide CLI" with HTML-slide authoring and PDF/PNG/PPTX export carves a mostly distinct niche with only minor overlap risk against generic presentation/pptx skills. Not a 5 because 'create/revise/export presentation decks' alone would collide with a general .pptx skill — the disambiguator is the CLI and HTML-stage framing rather than the triggers themselves; not a 3 because it is well beyond 'somewhat specific but could still overlap'.
