Conciseness

The body is lean and directive throughout — exact ratios ("one `interactive` or `quiz` page for every two pages"), required widgetOutline fields per widget type, and copy-paste example phrases, with no explanation of concepts Claude already knows. Brief framing lines ("This is where the style is heard, so it is the part to get right") are one-sentence emphasis, not padding. Not 4: virtually every token carries a rule or an example.

Actionability

Fully executable guidance for an instruction-only skill: per-widgetType widgetOutline field lists (e.g. "`game`: `concept`, `gameType`, `challenge`, `playerControls`"), roster composition with exact persona phrases to place (「short turns, question-first, encouraging」), where to put narration directives ("`generate_scene.materialFacts`" with sample text), and good/bad scene-title pairs. Not 4: the guidance is copy-paste ready and covers the common cases with no gaps.

Workflow Clarity

The sequence is clear — plan the outline in conversation, then "call `create_stage` and one `generate_scene` per page with an explicit brief", roster via `set_roster`, then per-page content and narration — and there are checkable rules ("If two explanatory pages ever sit next to each other, one of them is unnecessary"). Not 5: no explicit end-of-work validation pass (e.g., a final re-check of the cadence ratio, widgetType variety, and closing project after generation); the checkpoints are stated as invariants rather than as a verify-and-fix step. Not 3: the sequence and most checkpoints are present and unambiguous.

Progressive Disclosure

This is a single-file skill (~115 lines) with no bundle files; content is well-organized under clear section headers (The shape, Slides are task briefs, widgetOutline, Narration is facilitation, The roster, Carrying the style into the generators, Scene naming) with no nested references and nothing inlined that belongs in a separate file. Nothing needs splitting at this size.

Specificity

The description enumerates multiple concrete design behaviors — "an exercise or a check every couple of pages", "short slides that only set up the next task", "guiding narration that asks more than it tells", "a closing page where the pieces come together in one small project" — with comprehensive coverage of what the skill does. Not 4: there are no meaningful gaps; every clause states a specific capability rather than a generic one.

Completeness

The first sentence explicitly answers 'what' (hands-on workshop with exercise cadence, task-brief slides, facilitation narration, integrating closing project) and the second sentence provides an explicit "Use when..." clause with concrete trigger phrases. Both halves are clearly and concretely stated, matching the 5 anchor exactly.

Trigger Term Quality

Triggers are comprehensive and natural, in both English ("workshop", "a bootcamp session", "a skill the learner is meant to leave holding", "the user names this style") and Chinese (「动手」「实操」「练中学」「边做边学」). Not 4: it is hard to name a natural phrasing a user would actually say for this style that is missing in either language.

Distinctiveness Conflict Risk

Explicit negative boundaries — "Not for a systematic explanatory course (that is `lecture-style`) and not for occupational procedure training with tools and safety gates (that is `vocational`)" — carve out a clear niche with minimal conflict risk against the named sibling skills.
