Conciseness

The body is information-dense and assumes Claude's competence (no "what is a pptx" padding), but the same gotchas are restated repeatedly: the `\$` / `\n` shell-escaping rules appear in "Shell & Execution Discipline", again under "No `\$` literals in slide text" in the visual delivery floor, and a third time in the Pitfalls table; the `.data.results[]` JSON-schema note appears in both "Reading & Analysis" and recipe (c); contrast floors are specified twice. That is more than minor duplication — matches "mostly efficient but could be tightened", not anchor 4's "minor instances", and well above anchor 2 since nothing explains concepts Claude already knows.

Actionability

Everything is executable and copy-paste ready: the Quick Start builds a real minimal deck, recipes (a)–(f) give exact commands with pre-computed cm coordinates and hex colors, the QA gates are runnable shell scripts, and the Pitfalls table pairs each trap with its concrete fix. Not 4: no gaps — the common cases (cover, data slide, flowchart, KPI grid, decision tree) each have a complete runnable block.

Workflow Clarity

A numbered Common Workflow (1–7) enforces incremental validation ("One command → check exit code → continue", "get --depth 1" after structural ops), and the QA section is exactly the anchor-5 feedback loop: Gates 1/2/2b/3 with REJECT-and-exit semantics, a mandatory fix-verify loop capped at 3 cycles with a convergence criterion, and an escalation protocol when it doesn't converge. Batch/deck operations have emphatic, explicit validation.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ all absent), so everything is inline in a ~587-line single file. Section structure and headers are clear, and detailed prop schemas are delegated to `officecli help` (a well-signaled external reference), but large blocks that clearly belong in separate reference files are inlined — the 8-row font-pairing table, 10 full color palettes, and 6 complete recipes — matching anchor 3's "content that should be separate is inline". Not 2: structure is strong, not minimal; not 4: the split opportunity is more than a minor organization gap at this file size.

Specificity

Enumerates multiple concrete actions — "creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file; editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments" — covering creation, extraction, editing, merge/split, and metadata features with no meaningful gaps. Not 4: coverage is comprehensive rather than having only minor gaps.

Completeness

Explicitly answers both questions: what ("This includes: creating... reading, parsing, or extracting... editing, modifying, or updating...") and when ("Trigger whenever the user mentions 'deck', 'slides', 'presentation', 'pitch', or references a .pptx filename") with concrete trigger phrases. Not 4: the 'when' clause is fully explicit, not merely present.

Trigger Term Quality

Natural triggers are present and varied — "'deck', 'slides', 'presentation', 'pitch', or references a .pptx filename" — including synonyms and the file extension. Not 5: it omits "PowerPoint", the single most common term users would say when needing this skill.

Distinctiveness Conflict Risk

Firmly anchored to a clear niche (.pptx manipulation) with distinct, specific triggers — comparable to the anchor-5 PDF example. Not 4: only the broad word "presentation" carries any overlap risk, and the .pptx scoping and enumerated capabilities keep conflict minimal.
