Lean ~50-line body with every line earning its place; it assumes Claude's competence and never explains concepts Claude already knows (no definitions of skills, mashups, or HTML). Matches the level-3 'lean and efficient' anchor; not level 2 because there is no unnecessary explanation to tighten.

As an instruction-only creative skill it gives concrete, specific guidance: a 1-to-3-skill selection rule, enumerated combination principles and theme ideas, three explicit fallback options ('Search today's news... then create a beautifully designed HTML artifact'), and good/bad reveal examples. Per the rubric's instruction-only note, absence of code is not penalized when guidance is this actionable; matches level 3.

A clear five-step sequence (Discover, Plan, Fallback, Execute, Reveal) with an explicit branching fallback at Step 3. The rubric's validation cap applies to destructive/batch operations, which this creative skill does not perform, so the absence of validate-fix-retry loops does not cap the score; the sequence is unambiguous and matches level 3.

The skill is under 50 lines, needs no external references (no references/scripts/assets bundle exists), and is organized into clear Workflow and numbered Step sections. Per the rubric's simple-skills note, well-organized sections alone qualify for level 3 here.

Names the domain and a couple of actions ('dynamically discovering and creatively combining other enabled skills') but only ~2 abstract actions, and pads with fluff ('delightful, unexpected "wow" experience') rather than listing multiple concrete capabilities. Not level 3 because it lacks several specific concrete actions like the anchor's extract/fill/merge; not level 1 because it does state concrete actions rather than pure abstractions.

Clearly answers both what ('Create a delightful... experience by dynamically discovering and creatively combining other enabled skills') and when with explicit trigger guidance ('Triggers when the user says "surprise me"...'). Meets the 'explicit trigger guidance' bar that would otherwise cap completeness at 2.

Good coverage of natural phrases users would actually say: 'surprise me', 'bored', 'wants inspiration', and 'something interesting'. Matches the level-3 anchor's breadth of natural terms; not below because it is not missing common variations.

A clear niche (unexpected creative mashup of other skills) anchored by the distinctive 'surprise me' trigger, unlikely to fire for the wrong skill. Not level 2 because the primary trigger is distinct rather than broadly overlapping; minor overlap risk with general 'inspiration' skills keeps it from being a perfect fit but still meets the level-3 anchor.
