Conciseness

Mostly information-dense (no explanations of concepts Claude already knows), but noticeably tightened-by-editing residue: the brief-only boundary is restated at least four times ('never copies a downstream skill's template... and never post-processes rendered HTML or PPTX' appears in Positioning, the OPC P block, invariant 1, and rule 4's postMessage clause), version noise ('v0.6.4' in two headings and five invariants contradicts the frontmatter's 'version: 1.1.1', and 'formerly the QA loop, CLI flag still --qa-from') is history, not instruction, and rule 12's dense WorkBuddy packaging paragraph duplicates references/workbuddy-team-packaging-and-video-materials.md. It could be tightened but is not padded — fits anchor 3 rather than 2.

Actionability

Concrete, executable surface throughout: an 18-artifact output contract with exact filenames and JSON shapes ('slide_plan.json... per-page media: {image, diagram, video} decision and layout_hint'), named CLI flags (--qa-from, --style-gallery, --renderer ppt-master, --out with a precise auto-wipe/refusal rule and --force), and named scripts. The gap keeping it below 5: not a single complete example invocation appears in the body, and the pointer for them ('Full CLI examples... live in docs/local-demo.md') targets a file that does not exist in this bundle.

Workflow Clarity

The O→P→Q→C workflow is a clear end-to-end sequence with explicit validation checkpoints and a bounded feedback loop: two human review gates before rendering (outline preview, style gallery), QA iterations that 'write qa_report.md, fix_prompt.md, and qa_iteration.json', a hard cap ('The presentation checkup caps at 3 iterations. Round 4 with remaining fail findings is needs-human'), and a destructive-output safeguard (--out refuses to wipe unless it is empty, missing, or a prior Humanize run, else requires --force). This matches the 5 anchor: explicit validation, error-recovery loop, and escalation to a human.

Progressive Disclosure

The 'Operational references' section is well-signaled with one-line annotations and the references/ files it cites all exist, but five paths the body points to are absent from the bundle: 'adapters/ppt-master-bridge-notes.md', 'registry/renderer_registry.json' (cited as the machine-readable source of truth for support levels), 'SPEC.md', 'docs/index.md' ('Full annotated index of all references'), and 'docs/local-demo.md' (which holds all CLI examples). Combined with inline content that duplicates an existing reference (rule 12), navigation is partly broken — fits anchor 3 ('references present but... content that should be separate is inline') better than 4's 'minor organization gaps'.

Specificity

The description enumerates concrete pipeline actions — 'turns raw material into an AST (audience-state-transfer) outline with per-page visual-enhancement decisions (image / SVG diagram / video), hands a production brief to a downstream renderer..., then runs a capped 3-round presentation checkup' — which is comprehensive coverage matching the 5 anchor. However, it slips into second person ('If all you want is one beautiful template page... a rendering skill alone is enough'), which the judging guidelines penalize by reducing specificity by 1.

Completeness

Both what and when are explicit: the what is the full outline/brief/checkup pipeline ('It never renders slides itself'), and the when gives concrete trigger phrases ('Use before generating PPT/HTML slides from raw material, and after rendering when the user says things like...') — this matches the 5 anchor example's structure exactly.

Trigger Term Quality

Comprehensive natural-term coverage with synonyms and extensions: 'PPT', 'PPTs', 'slides', 'HTML slides', 'deck', 'native PPTX', plus concrete user-utterance triggers in both English and Chinese ('给这份 deck 做演讲体检', 'PPT 渲染质检'). A user asking to make a presentation or check a rendered deck would naturally use these phrases.

Distinctiveness Conflict Risk

It carves out a clear niche (brief orchestrator + post-render checkup) and explicitly disambiguates from rendering skills ('It never renders slides itself... a rendering skill alone is enough'), giving minimal conflict risk with the downstream renderer skills it names.
