Conciseness

The body is dense and assumes competence — no concept padding, tables used effectively — but the 'Receipts' quotes duplicate content already in references/quotes.md, and play details overlap references/frameworks.md, so a meaningful amount could be trimmed or moved. Efficient with minor instances of removable content rather than over-explanation.

Actionability

Fully executable instruction-only guidance: exact diagnostic questions to ask, step-by-step play procedures with worked examples (LevelJump so-what ladder, Square Stand H1), a copy-paste-ready markdown deliverable template, and a 1/3/5 grading rubric with a specified output format.

Workflow Clarity

Clear Step 1 (diagnose, capped at 4 questions) → Step 2 (routing table) → Step 3 (run the play) sequence with explicit validation checkpoints: a 'Done when' criterion, the Bar Test and swappable test, category readiness factors, prospect testing with lean-in logging, and abandon-if-not-adopted feedback loops.

Progressive Disclosure

Two real, one-level-deep references (references/frameworks.md, references/quotes.md — both verified present) are clearly signaled under 'Go deeper' with descriptions. However, the body is more than an overview: play detail overlaps frameworks.md and the receipts section duplicates quotes.md, so the split is not fully clean.

Specificity

Lists multiple concrete actions — 'Builds a positioning canvas (competitive alternatives, differentiated value, best-fit customer, category) plus a strategic narrative and sales-pitch storyboard, and grades existing positioning or messaging' — covering the skill's full functionality with specifics, not vague domain labels.

Completeness

Explicitly answers both 'what' (builds a canvas, strategic narrative, storyboard; grades existing positioning) and 'when' via a concrete 'Use for...' clause listing trigger phrases, matching the anchor example's structure.

Trigger Term Quality

The trigger list combines formal terms ('positioning', 'category', 'differentiation', 'value prop') with natural user phrasings ('how do we describe our product', 'our pitch isn't landing', 'one-liner', 'old game new game'), giving comprehensive natural-keyword coverage for this domain.

Distinctiveness Conflict Risk

The positioning/messaging niche is clear with distinct triggers, but broad terms like 'messaging', 'one-liner' and 'value prop' carry minor overlap risk with closely related marketing, launch and pricing skills (which the skill itself lists as neighbors).
