Conciseness

Largely imperative with no conceptual padding (no 'what is Google Slides' explanations), but several principles are restated across sections: the exemplar-fit/typography rules repeat the same guidance in consecutive paragraphs (e.g., the 12 pt floor and 'choose a better exemplar' appear in both lines 143 and 145, and again at 157), and read-once/reuse rules appear in both 'Work Efficiently' and the parse/render sections. Matches anchor 3 — mostly efficient but could be meaningfully tightened; not 4 because the repetition is more than minor.

Actionability

Provides copy-paste-ready commands with exact flags ('$NODE $SKILL_DIR/scripts/parse_template_design_system.mjs --input ... --output ...'), concrete thresholds (dpi: 120, 12 pt floor, max two repair passes), and full executable JS blocks. Not 5 because the two JS blocks load 'host/read-template-to-file.mjs' and 'host/export-and-render-slides.mjs' via a cat-and-eval pattern that are not present in the bundle, and 'the workspace dependency loader' is invoked without any pointer to where it lives.

Workflow Clarity

A clearly sequenced pipeline (route → parse template → render → build from exemplars → consolidated QA) with explicit validation checkpoints: the issue checker must pass before rendering ('Repair every error before rendering'), one structural readback to confirm delivered slide IDs before reordering, page-count mismatch causes a hard failure, and bounded feedback loops ('Do not perform more than two repair passes', re-render after structural rebuilds). Exemplifies the anchor-5 validation-and-recovery pattern; not 4 because no checkpoint is implicit.

Progressive Disclosure

The two bundled scripts are well-signaled with their exact CLI invocations, but the ~150-line Build section is a dense wall of procedural rules (typography, exemplar selection, media handling) that would naturally live in a separate reference file, and the body references 'host/*.mjs' helper files that do not exist in the bundle, while the bundled assets/ images are never mentioned. Anchor 3: some structure, but content that should be separate is inline and navigation to parts of the bundle is broken.

Specificity

Names several concrete actions — 'Route Google Slides authoring requests', 'derive a design system from a native template or reference deck', and 'edit, update, repair, restyle, or clean up an existing native Google Slides deck' — with only minor coverage gaps (e.g., template-driven slide construction itself is only implied). It sits between anchor 4 (several specific actions, minor gaps) and anchor 5 (comprehensive); not 5 because the core authoring activity is described via routing rather than enumerated capabilities.

Completeness

Explicitly answers both: what ('Route Google Slides authoring requests and derive a design system from a native template or reference deck') and when ('Use this skill when the user provides an existing native Google Slides deck as a template, reference, or prior-period source, or asks to edit, update, repair, restyle, or clean up...'), plus an explicit negative trigger for the sister skill. Matches the anchor-5 example structure exactly; not 4 because the 'when' clause is fully explicit rather than merely adequate.

Trigger Term Quality

Includes natural user phrases such as 'Google Slides', 'template', 'reference deck', 'prior-period', and the strong verb list 'edit, update, repair, restyle, or clean up an existing native Google Slides deck'. Below 5 because common synonyms like 'presentation', 'slides', or 'deck' as standalone triggers only appear indirectly ('deck' always qualified as 'native Google Slides deck').

Distinctiveness Conflict Risk

Clear niche — working from an existing *native* Google Slides deck — and it explicitly disambiguates against the nearest competitor: 'Use the Presentations skill instead for net-new presentation creation when no existing native Google Slides deck must be followed.' Minimal conflict risk; nothing pushes it off anchor 5.
