Conciseness

The body is efficient — every section (Tools, Workflow, Output, Safety, boundaries) is purposeful with no concept explanations Claude already knows. It is not a 5 because the 'Good Triggers' section largely restates trigger phrasing already present in the always-loaded frontmatter description, a minor instance that could be trimmed.

Actionability

The guidance is fully concrete for an instruction-only skill: exact MCP tool names (get_file_metadata, list_shared_links, get_shared_link_metadata, fetch, search, list_folder), per-condition routing for each user intent, explicit pagination handling ("continue while the response indicates has_more or returns a cursor"), and explicit statements of unavailable capabilities. Per the scoring notes, absence of code is not penalized when guidance is this actionable, and common cases are covered.

Workflow Clarity

The 7-step workflow is clearly numbered and sequenced with conditional routing for ambiguity, content requests, sharing questions, and link-specific queries, plus an explicit validation checkpoint ("continue while the response indicates has_more or returns a cursor before claiming the shared-link listing is complete"). The skill is read-only with no destructive or batch operations, so the validation cap does not apply.

Progressive Disclosure

The skill is under 50 lines with no need for external references (no references/, scripts/, or assets/ directories exist, and the body references no bundle files), and it is cleanly organized into well-labeled sections (Tools, Workflow, Output, Safety, Good Triggers, Do Not Use When). Per the rubric's simple-skill exception, well-organized sections alone score 5 here.

Specificity

The description names the domain ("Dropbox file or folder") and three concrete actions — "checking metadata, shared links, and file content" — matching the anchor for several specific actions with minor gaps. It is not a 5 because coverage is not comprehensive (no mention of folder listing or search-based disambiguation), and not a 3 because it lists more than 1-2 actions.

Completeness

It explicitly answers both "what" ("Inspect a Dropbox file or folder by checking metadata, shared links, and file content when needed") and "when" ("Use when the user asks what a file is, whether it is shared, when it changed, what access links exist, or asks to read/analyze a Dropbox file") with concrete trigger phrases, matching the anchor-5 example structure. A clear "Use when" clause is present, so the completeness cap does not apply.

Trigger Term Quality

Trigger phrases like "what a file is", "whether it is shared", "when it changed", and "read/analyze a Dropbox file" are natural user phrasings, giving good keyword coverage. It falls short of 5 because common synonyms and variations (e.g., "view file details", "file info", "open a Dropbox file") are missing.

Distinctiveness Conflict Risk

"Inspect a Dropbox file or folder" carves out a clear inspection niche with distinct triggers, but closely related sibling skills (search/browse, sharing) exist and the description does not delineate boundaries against them — e.g., "whether it is shared" could plausibly route to a sharing-inspection skill. This is mostly distinct with minor overlap risk, not a 5 with minimal conflict risk.
