Conciseness

The body is short and does not explain concepts Claude already knows, but the exact phrase 'aws development with infrastructure automation and cloud architecture patterns' is repeated verbatim in the Overview, When to Use, and Instructions sections — duplicated padding that adds no information. This matches anchor 3 ('mostly efficient but... could be tightened'); it is not anchor 5 because those repeated tokens earn nothing, and not anchor 2 because there is no over-explanation and the total budget wasted is small.

Actionability

The Instructions section states only 'This skill provides guidance and patterns for aws development...' — it describes rather than instructs, with no code, commands, examples, or specific steps anywhere in the body. This exactly matches anchor 1 ('entirely vague or abstract; no concrete code or commands; only describes rather than instructs').

Workflow Clarity

There are no steps or sequence of any kind — the body is three restatements of the description plus a repository link. This matches anchor 1 ('steps missing or incoherent; no sequence; no validation for risky operations'); it cannot score higher because even a rough sequence is absent.

Progressive Disclosure

The skill is under 50 lines, has no bundle files (references/, scripts/, assets/ do not exist), and needs no external references as written; per the simple-skill scoring note it can score 5 with well-organized sections alone. The body has a clean, standard section structure (Overview, When to Use, Instructions) plus a clearly signaled one-level-deep source link, making it trivially navigable.

Specificity

The description names the domain ('AWS development') and sub-areas ('infrastructure automation', 'cloud architecture patterns') but contains no concrete actions or verbs at all. It sits between anchor 1 (no concrete actions, pure abstraction) and anchor 2 (domain named, actions minimal/generic) — the named sub-domains lift it just above pure abstraction, but not to anchor 3, which requires 1-2 concrete actions.

Completeness

The 'what' is only a vague topic list ('AWS development with infrastructure automation and cloud architecture patterns') and there is no 'Use when...' clause or equivalent trigger guidance, exactly matching anchor 2 ('has a vague what and no when'). Per the guideline, the missing 'Use when' clause caps completeness at 3, and the vague 'what' pushes it below that to 2.

Trigger Term Quality

'AWS' is a strong natural keyword and 'infrastructure automation' and 'cloud architecture' are phrases users would plausibly say, matching anchor 3 ('some relevant keywords but missing common variations or synonyms'). It falls short of anchor 4 because common natural terms are absent — no service names (EC2, S3, Lambda), no IaC tools (Terraform, CloudFormation), no 'serverless', 'deploy', or file extensions.

Distinctiveness Conflict Risk

The AWS qualifier gives it some specificity, but 'AWS development' is an extremely broad claim that would overlap with any AWS-service-specific, DevOps, or infrastructure-as-code skill, matching anchor 3 ('somewhat specific but could still overlap with similar skills'). It is not anchor 4 because no distinct niche or trigger is carved out.
