Conciseness

The body is dense, imperative, and free of explanations of concepts Claude already knows — nearly every line is a contract, command, or gate. Minor trimming opportunities remain, e.g., the migration-framing lines "Treat self-containment as a path/import/entrypoint migration, not a redesign of reconstruction behavior" and "Never re-author an accepted baseline page merely to prove runtime independence" restate one policy point twice, which keeps it at anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Every step is a copy-paste-ready command with concrete flags: `cli.py doctor --json`, `prepare ... --out-root output/image2ppt --image-backend builtin-imagegen`, `run next <run-dir> --json`, `run dispatch ... --prompt-file <absolute-prompt>`, `page build <page-dir>`, `run_image2ppt_qa.py <page-dir> --visual-review-status reviewed --visual-review-evidence ...`. Placeholders like `<run-dir>` and `<page-id>` are genuine parameters, not pseudocode, and the two-pass visual-review-evidence workflow is spelled out concretely, matching anchor 5.

Workflow Clarity

The five-phase sequence (preflight/OCR → prepare → advance/claim → reconstruct-and-gate → finalize) is explicit and numbered, with validation checkpoints at every stage: "Do not continue after a failed doctor", record "only after standard validation and the Image2PPT region, arrow, and rendered gates pass", and "Do not call the deck complete while any page/final gate is pending or failed". Error-recovery feedback loops are present ("install only the reported missing dependency, then rerun it"; "repair if needed"; the `run reset` → dispatch → record repair lifecycle), satisfying the batch-operation validation requirement and matching anchor 5.

Progressive Disclosure

The body is a navigable overview with conditionally-scoped, one-level-deep references: "Always read `references/workflow.md`", "read `references/runtime-dependencies.md` only for setup or `doctor` failures", "read `references/ocr-text-hints-contract.md` only when choosing or troubleshooting OCR", plus per-page-type references and a pre-delivery `references/qa-contract.md` gate. All referenced files exist in `references/` and all cited scripts exist in `scripts/`, and nothing is nested two levels deep — matching anchor 5.

Specificity

The description names two concrete actions — "Reconstruct slide images, screenshots, scanned PDFs, or image-only PPTX files as object-level editable PowerPoint" and "diagram reconstruction" — with precisely enumerated input types and a specific output format. It falls just short of anchor 5 because the actions reduce to a single reconstruction family rather than multiple distinct concrete actions, and it exceeds anchor 3 because input coverage is comprehensive and the transformation is precisely characterized.

Completeness

It explicitly answers both questions: "what" via "Reconstruct ... as object-level editable PowerPoint" and "when" via "Use for 图片转可编辑PPT、截图还原PPT and diagram reconstruction", with concrete trigger phrases and an explicit negative boundary ("not authoring a new deck from research notes"). This matches the anchor 5 example pattern exactly and cannot be score 4 since the "when" clause is already fully explicit with specific triggers.

Trigger Term Quality

Good keyword coverage including "slide images", "screenshots", "scanned PDFs", "image-only PPTX", "editable PowerPoint", "diagram reconstruction", plus natural Chinese trigger phrases ("图片转可编辑PPT、截图还原PPT") and the PPTX extension. A few natural English variants users would say (e.g., "image to PowerPoint", "convert screenshot to slides") are missing, so it fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

It occupies a clear niche (image/screenshot-to-editable-PPT reconstruction) with distinct triggers, and the exclusion clause "not authoring a new deck from research notes" actively prevents overlap with presentation-authoring skills. Minimal conflict risk, matching anchor 5 rather than anchor 4 which would require some overlap with closely related skills.
