Mostly lean without concept-padding, but the checklist, flowchart, and 流程详解 sections restate the same sequence, and the 可视化伴侣 section is lengthy enough that the body could be tightened.

Provides concrete, executable guidance for an instruction-only skill: numbered ordered checklist, specific output path docs/specs/YYYY-MM-DD-<主题>-design.md, one-question-per-message rule, a 4-point spec self-review, and quoted user-facing prompts.

Clear sequenced process with a flowchart and explicit validation checkpoints (规格自审 -> fix in place -> user review gate -> revise loop), matching the clear-sequence-with-feedback-loops anchor.

References to spec-document-reviewer-prompt.md and visual-companion.md are signalled ("在本 skill 目录中") but those referenced markdown files are absent from the skill directory, so the disclosure structure is partly broken.

Lists concrete actions ("Explore user intent, requirements, and design options", "collaborative dialogue before implementation") rather than vague language, matching the multiple-specific-actions anchor.

Explicitly answers what (explore intent/requirements/design options via collaborative dialogue) and when ("Use before building new features..." with an explicit Triggers list and a "Not for..." clause).

Natural user phrases like "brainstorm", "help me design", "think through the requirements" plus Chinese variants give good coverage of terms users would actually say.

Clear pre-implementation design niche with distinct triggers and explicit negative guidance ("Not for bug fixes, config changes, or tasks with an obvious implementation path") that prevents mis-triggering.
