Conciseness

The core process, phases, and output template are tight and earn their tokens, but three sections repeat the same points nearly verbatim: "5-8 well-considered variations beat 20 shallow ones. Quality over quantity" appears in both Anti-patterns and the Common Rationalizations table, as do "A yes-machine produces weak ideas", "Untested assumptions are the #1 killer", and "The Not Doing list is arguably the most valuable part", with Red Flags restating them a third time. Mostly efficient, but a clear tightening opportunity — fits the 3 anchor; not 2 because the process guidance itself is not padded.

Actionability

Strong concrete guidance exists — specific counts ("Ask 3-5 sharpening questions", "Generate 5-8 idea variations"), named tools (AskUserQuestion, Glob/Grep/Read), a full copy-paste output template, and a save path. But it instructs "Read `frameworks.md`", "Read `refinement-criteria.md` for the full evaluation rubric", and "Read `examples.md`" — none of these files exist in the bundle, so key details (especially the full Phase 2 rubric) are missing. Concrete but incomplete matches the 3 anchor better than 4.

Workflow Clarity

Three phases are clearly sequenced with explicit checkpoints and gating: "Do NOT proceed until you understand who this is for and what success looks like", Phase 2 only "After the user reacts to Phase 1", "Only save if they confirm", and a final Verification checklist. This matches the 5 anchor (clear sequence, explicit validation steps, checklist for a complex process); this is a conversational, non-destructive skill so the destructive-operation cap does not apply.

Progressive Disclosure

The body is well-structured with sections, and detail is deferred via clearly signaled one-level-deep references ("Read `frameworks.md` in this skill directory", "Read `refinement-criteria.md`", "Read `examples.md`"). However, none of those three files exist in the bundle — only scripts/idea-refine.sh is present — so the navigation is broken and the deferred content is unavailable. Not 4/5 because the references point to nonexistent files; not 2 because the in-body structure and signaling themselves are good.

Specificity

The description lists several concrete actions — "Refines raw ideas into sharp, actionable concepts", "stress-test assumptions before committing to a plan", "expand options before converging on one" — matching the 'several specific actions with minor gaps' anchor. It falls short of 5 because "structured divergent and convergent thinking" is process jargon and no concrete artifact or outcome is named; it is above 3 because more than 1-2 actions are specific.

Completeness

Explicitly answers both: what ("Refines raw ideas into sharp, actionable concepts through structured divergent and convergent thinking") and when ("Use when an idea is still vague, when you need to stress-test assumptions before committing to a plan, or when you want to expand options before converging on one. Triggers on..."). The 'Use when' clause with concrete trigger phrases matches the 5 anchor exactly.

Trigger Term Quality

Natural phrases users would actually say are present: "ideate", "refine this idea", "stress-test my plan", "an idea is still vague". Not 5 because common synonyms like "brainstorm", "flesh out this idea", or "pressure-test" are missing; clearly above 3 since multiple natural trigger phrases are covered.

Distinctiveness Conflict Risk

The ideation/refinement niche ("Refines raw ideas... stress-test assumptions") is mostly distinct with a clear identity, but there is minor overlap risk with brainstorming or planning skills since broad terms like "plan" and "assumptions" appear, and no boundary against adjacent skills is stated in the description itself. Fits the 4 anchor better than 5.
