Conciseness

The body is lean and assumes Vue competence: a complete setup snippet, terse Wrong/Correct mistake pairs, and one-line source citations, with no concept padding. The only near-redundant token is the opening 'This skill builds on...' line that duplicates frontmatter requires, which is not enough to drop below anchor 5.

Actionability

The Setup block is complete, executable code (useTable with key/features, useTanStackTableDevtools(table)) and API Discovery names exact .d.ts files to inspect, but the pivotal plugin registration ('Mount the Vue TanStackDevtools host once with tableDevtoolsPlugin({})') is prose only — never shown in code, leaving a minor gap between anchor 4 and the copy-paste-ready coverage of 5.

Workflow Clarity

A clear sequence is discernible (create table → attach hook → mount host once), and the Common Mistakes section doubles as error-recovery guidance (ref unwrapping, duplicate keys, dev-only gating). It is not a 5 because the placement of the plugin mount (app setup vs component) and the hook/plugin ordering are implicit rather than explicitly sequenced; the task is non-destructive so no validation loop is required.

Progressive Disclosure

A compact single-purpose skill (~45 non-blank body lines) with no bundle files and no need for external references: content is appropriately inline, sections are well-organized (Setup, Hooks and Components, Common Mistakes, API Discovery), and there is no reference nesting. Fits the simple-skill case with clean structure.

Specificity

Names concrete APIs ('tableDevtoolsPlugin', 'useTanStackTableDevtools') and specific operations ('Connect Vue Table v9 refs or instances to Devtools'), listing several specific actions with only minor gaps (setup and mounting detail is left to the body). It is well above the '1-2 concrete actions' of a 3 but not the comprehensive action coverage of a 5.

Completeness

Explicitly answers both: the 'what' ('Connect Vue Table v9 refs or instances to Devtools with tableDevtoolsPlugin and useTanStackTableDevtools') and the 'when' via an explicit trigger clause ('Load for missing targets, reactive table replacement, required options.key, enabled state, cleanup, or development gating') with concrete trigger phrases.

Trigger Term Quality

'missing targets', 'reactive table replacement', 'required options.key', 'enabled state', 'cleanup', 'development gating', and 'Devtools' are natural phrases a user would report when hitting these problems. A few common variations (e.g., 'panel not showing', 'devtools blank in production') are missing, matching anchor 4 rather than 5.

Distinctiveness Conflict Risk

Pins an exact niche (library 'vue-table-devtools', framework Vue, version v9, two named APIs), so it is clearly distinguishable from other table or devtools skills with minimal conflict risk. The voice is third-person imperative with no first/second-person penalty.
