Conciseness

The body is lean and assumes competence — no explanations of concepts Claude already knows, and tight imperatives like 'Tighten copy before shrinking fonts.' A few bullets are wordy and jargon-heavy (e.g., 'Support self-contained portable-builder reports whose native charts and builder-generated semantic chart-data representations remain available...'), which keeps it just below the every-token-earns-its-place anchor.

Actionability

Guidance is fully executable: a copy-paste bash command with the real script path (scripts/report_to_google_slides.py, verified to exist) and arguments, the concrete output files to inspect (deck.pptx, manifest.json, deck_plan.json, preflight_checks.json, assets/), named MCP import tool with the exact parameter (mcp__codex_apps__google_drive._import_presentation, upload_mode="native_google_slides"), and a concrete verification command (unzip -t <out-dir>/deck.pptx).

Workflow Clarity

The six-step workflow is clearly sequenced with explicit validation gates and a feedback loop: 'Do not import the PPTX until preflight_checks.json has status: "passed"', zip-integrity check before import, thumbnail verification of specific slide types, and step 5's repair-then-regenerate loop before handoff. This matches the anchor with explicit validation steps and error-recovery loops.

Progressive Disclosure

The body is a well-organized overview (intro, Workflow, Standards, Visual System) with the heavy lifting correctly delegated to the one-level-deep script reference, which exists in the bundle (scripts/report_to_google_slides.py). No buried or nested references, no content that belongs in a separate file, and easy navigation.

Specificity

The description names the domain ("convert an existing HTML analytics report into a native Google Slides deck") and one concrete action — conversion. It does not enumerate multiple specific capabilities (e.g., chart rendering, table conversion, preflight checks, import), so it matches the 'names domain and 1-2 concrete actions' anchor rather than the 'lists several specific actions' anchor above.

Completeness

Both parts are present: the 'what' ("Narrow conversion skill" converting an HTML analytics report into a native Google Slides deck) and a very explicit 'when' ("Invoke only when the user explicitly asks to convert..."). The 'when' meets the top anchor, but the 'what' is terse — it does not state concrete trigger phrases for the capability side nor what the deliverable includes, keeping it at the 'both present, could be more explicit' level rather than 5.

Trigger Term Quality

Natural trigger phrases are present — "convert", "HTML analytics report", "Google Slides", "deck" — which map well to what a user would say. A few natural variants are missing ("presentation", "PowerPoint", ".pptx", "slides"), so it falls just short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The description carves out a clear niche (HTML analytics report → native Google Slides deck) with an 'only when the user explicitly asks' guard, minimizing overlap with generic presentation or document skills. The trigger is highly specific and unlikely to fire for the wrong skill.
