Conciseness

Mostly efficient — no explanations of concepts Claude already knows — but the "When to Use"/"When NOT to Use" bullet lists duplicate the frontmatter description, and the Integration section re-states "run all three sequentially. Each builds on the previous." These could be trimmed for a tighter body.

Actionability

Fully followable for an instruction-only skill: explicit stepwise procedures (C1–C4, E1–E4, T1–T4) with fill-in templates, enumerated transformation types ("Inversion | Relaxation | Substitution | Elimination"), a concrete ranking formula ("Rank passing solutions by (Utility × Novelty)"), and a complete worked example (single-lane bridge) demonstrating all three paradigms.

Workflow Clarity

Clear sequence (Phase 0 → paradigm selection → paradigms → tiered portfolio) with checkpoints ("Select top 2 solutions" after each paradigm; feasibility pass/fail gate). Not 5 because there is no feedback loop telling Claude what to do when solutions fail the feasibility gate.

Progressive Disclosure

Good section headers make the ~250-line body navigable, but everything is inline with no reference files; the per-paradigm templates are prime candidates for one-level-deep reference files (e.g., references/combinational.md), keeping SKILL.md as an overview with the selection table and integration pipeline.

Specificity

Lists several concrete capabilities — "Implements three paradigms — combinational (novel combinations of familiar ideas), exploratory (expand solution space boundaries), transformative (alter fundamental constraints)" — each with a clear definition. Not 5 because it omits deliverables (e.g., a tiered portfolio of solutions) and output specifics, leaving minor coverage gaps.

Completeness

Explicitly answers "what" (a creative reasoning framework implementing three named paradigms with definitions) and "when" ("Use when the problem has ambiguous goals, vast solution space, no single correct answer, or requires innovation"), plus a negative trigger list ("Do not use for well-defined problems, mathematical puzzles, or tasks requiring convergent reasoning"). Both halves are concrete and explicit.

Trigger Term Quality

Includes some relevant natural phrases ("ambiguous goals", "no single correct answer", "requires innovation") but misses common variations users would actually say such as "brainstorm", "ideation", "out-of-the-box", or "novel ideas". Coverage is moderate rather than good, matching anchor 3.

Distinctiveness Conflict Risk

The niche is distinct (creative reasoning for ill-defined problems) and the explicit exclusion list reduces mis-triggering, but "creative reasoning" and "innovation" still overlap broadly with generic brainstorming/ideation skills. Mostly distinct with minor overlap risk.
