Conciseness

Lean throughout: it jumps straight into inputs, formulas, and thresholds without explaining CSVs, inventory concepts, or libraries Claude already knows, so every token earns its place.

Actionability

Concrete formulas ('safety_stock = 1.5 × avg_daily_sales × lead_time_days'), exact file paths, numeric thresholds, and copy-paste JSON output shapes make the guidance fully executable.

Workflow Clarity

Decision rules are numbered 1–4 with an explicit confidence guard ('if confidence < 0.6, do not place a PO automatically') acting as a validation checkpoint and escalation feedback loop before any side effect.

Progressive Disclosure

A single self-contained file organized into clearly headed sections (Inputs, Decision rules, Worked example, Prioritization, Transfer vs reorder, Compliance, Output) with no nested references or wall-of-text problem.

Specificity

Names the domain ('reorder a SKU') and two decisions ('whether and how much') but does not enumerate multiple concrete actions, so it stops short of the multi-action anchor.

Completeness

'How to decide whether and how much to reorder a SKU' states what, and 'Load this whenever a task involves...' gives an explicit when-trigger, satisfying both halves.

Trigger Term Quality

'reorder recommendations, purchase orders, or "should we restock" questions' gives natural phrasings a user would actually say, including a quoted vernacular trigger.

Distinctiveness Conflict Risk

The reorder/purchase-order niche with 'should we restock' triggers is distinct and unlikely to fire for unrelated skills (it even defers to separate supplier/forecasting skills).
