The body is four sentences with no padding and no explanation of concepts Claude already knows — every token ('Walk down each branch of the design tree, resolving dependencies between decisions one-by-one', 'For each question, provide your recommended answer') earns its place; not the 2 anchor because there is no unnecessary explanation to tighten.

Concrete, specific guidance: 'Walk down each branch of the design tree, resolving dependencies between decisions one-by-one', 'provide your recommended answer', and 'explore the codebase instead' tell Claude exactly what to do; as an instruction-only skill the absence of code is not penalized, and the guidance is actionable, matching the 3 anchor; not the 2 anchor because the direction is complete and specific rather than vague or pseudocode-like.

For this simple single-purpose skill the iterative sequence — interview, traverse each branch, resolve dependencies one-by-one, give a recommended answer per question — is clear and unambiguous, and no destructive/batch validation checkpoint is required; the simple-skills note allows 3 for clear single-task content; not the 2 anchor because the sequence is explicit rather than implicit.

The body is two ungrouped paragraphs with no section headers or navigation, and while a 4-sentence skill needs no external references, it lacks the 'well-organized sections' the 3 anchor (and the simple-skills carve-out) calls for; not the 1 anchor because there is no monolithic wall of text or nested references, and not the 3 anchor because there are no organized sections.

Quotes 'Interview the user relentlessly about a plan or design', 'resolving each branch of the decision tree', and 'reaching shared understanding' — three concrete, distinct actions rather than vague language, matching the 'lists multiple specific concrete actions' anchor; it is not the 2 anchor because the actions are concrete and comprehensive for this domain rather than partial.

Explicitly answers what ('Interview the user relentlessly... resolving each branch of the decision tree') and when ('Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me"'), with an explicit 'Use when...' trigger clause; not the 2 anchor because 'when' is stated explicitly, not merely implied.

Quotes 'stress-test a plan', 'get grilled on their design', and 'grill me' — natural phrases a user would actually say, giving good coverage; it is not the 2 anchor because common variations are present rather than missing.

The niche — adversarial plan/design interviewing — is distinct, with unique triggers like 'grill me' and 'stress-test a plan' that are unlikely to fire for unrelated skills; not the 2 anchor because it does not overlap meaningfully with similar skills.
