Conciseness

The body is lean with no concept explanations Claude already knows (no 'what Dropbox is', no library-recommendation padding); every section — Tools, Workflow, Confirmation, Output, Safety, triggers — earns its place. It clearly matches the 'lean and efficient; every token earns its place' anchor rather than 4, where trimmable over-explanation would remain.

Actionability

Concrete tool names are given, conditions are executable ("continue while the response indicates has_more or returns a cursor"), and required output fields are enumerated. Per the instruction-only guideline, absence of code is not penalized; the 'Good Triggers' examples cover the common cases, matching the top anchor.

Workflow Clarity

The 8-step sequence is clear with strong checkpoints — target confirmed via get_file_metadata, pagination completeness tracked, and explicit confirmation before create — matching 'clear sequence with most checkpoints present'. It falls short of 5 because there is no error-recovery feedback loop beyond reporting warnings/partial failures (e.g., what to do if creation fails or settings cannot be applied).

Progressive Disclosure

This is a short, single-purpose skill with well-organized sections and no external references needed (and none are referenced — no bundle files exist). Per the under-50-lines guideline, well-organized sections alone warrant the top score.

Specificity

The description lists three concrete actions ("creating shared links, inspecting existing shared links, or explaining current shared-link state") in a named domain, matching the 'several specific actions; minor gaps' anchor. It falls short of 5 because coverage is not fully comprehensive — e.g., reporting the resulting URL/access settings after creation is not mentioned.

Completeness

It explicitly answers both 'what' (create, inspect, and explain shared-link state) and 'when' ("Use only when the user explicitly asks to create a shared link, check access, or inspect a Dropbox shared link") with concrete trigger phrases. This clearly matches the top anchor rather than 4, where the 'when' would be less explicit.

Trigger Term Quality

Phrases like "create a shared link", "check access", "inspect", and "Dropbox" are terms users would naturally say, giving good keyword coverage. It misses a few natural variations such as "send me a link" or "share this file with someone", keeping it below the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The Dropbox shared-link niche plus the restrictive "Use only when the user explicitly asks" clause give it distinct triggers and minimal conflict risk with adjacent skills (finding files, inspecting metadata). It clearly fits the 'clear niche with distinct triggers' anchor.
