Conciseness

The body is lean bullets across four short sections with no explanation of concepts Claude already knows and no padding; every section (Capabilities, Workflow, Signals, Output Format) earns its place. Matches the anchor-5 'lean and efficient' example.

Actionability

Guidance stays high-level: "Analyze which platforms/campaigns deliver best returns", "Recommend budget shifts with expected impact" — no data sources, no calculation method, no example allocation table, and no mechanism for implementing changes. It sits at anchor 2 (high-level hints missing specific steps) rather than 1 because a sequenced workflow and a defined output format are present, but nothing is concretely executable.

Workflow Clarity

The five-step workflow is clearly sequenced and includes one checkpoint ("Implement changes after user approval"), but implementing spend shifts across live campaigns is a batch operation with no validation or post-implementation verification step, which caps this dimension at 3 per the rubric guideline. Not 4 because the implementation step itself is undefined and checkpoints beyond approval are absent.

Progressive Disclosure

The skill is under 50 lines with no bundle files and no content that warrants external references; sections are well-organized and self-contained, which satisfies the rubric's simple-skill exception for a top score. Nothing is buried or nested.

Specificity

"Optimize budget allocation across ad platforms and campaigns" names the domain and a single core action, but omits the concrete operations the body actually covers (media plan creation, persona-based allocation, rebalancing recommendations). It matches anchor 3 (domain plus 1-2 concrete actions) rather than 4, which requires several specific listed actions.

Completeness

It has a clear 'what' and an explicit "Use when the user asks about..." clause with four concrete triggers. Not 5 because the 'what' is a single action rather than the comprehensive multi-action list in the anchor-5 example; clearly above 3 since both what and when are explicit.

Trigger Term Quality

"budget distribution, media planning, funnel-stage budgeting, or wants spend reallocation" gives good natural-phrase coverage a user would plausibly say. Not 5 because common variants like "ad spend", "advertising budget", or "ROAS" are missing; well above 3's 'some relevant keywords'.

Distinctiveness Conflict Risk

The niche (ad budget allocation, media planning, funnel-stage budgeting, spend reallocation) is mostly distinct with trigger terms unlikely to fire for unrelated skills. Not 5 due to minor overlap risk with generic marketing-analytics or media-buying skills.
