Conciseness

Every line is an instruction, a constraint, or a pointer ('The route file owns `chat()`', 'Do not add BYOK files by default') with zero padding and no explanation of concepts Claude already knows. It assumes competence throughout and matches the 'lean and efficient; every token earns its place' anchor rather than the 4 anchor, which would require trimmable over-explanation.

Actionability

Guidance is copy-paste ready throughout: the exact generator command ('pnpm nx g @tanstack/workspace-plugin:react-app <slug>'), exact paths ('examples/react/<slug>/', 'src/routes/api.chat.ts'), the sandbox comment template, the config child ('framework/react/examples/<slug>'), and the GitHub link format. It matches the 5 anchor — executable commands covering the common cases; a 4 would imply missing key details, and none are evident.

Workflow Clarity

The sequence is explicit and well-ordered (shape the app → file layout → tutorial page → nav and pointers → PRs) with an upfront 'End state' checklist, a 'Common mistakes' diagnosis table, and one honesty gate ('Do not tick test:pr if it was not run'). It falls short of 5 because there is no explicit build/run validation checkpoint before opening the PR (e.g., verifying the example builds or the tutorial page renders), leaving verification implicit rather than a feedback loop.

Progressive Disclosure

The skill is a single well-organized file with clear section headers, an end-state checklist, and a mistakes table; no bundle files exist (references/, scripts/, assets/ are absent), and detail is appropriately delegated to named sibling skills ('Load `docs`, `simple-english`, and `i-have-adhd`') which are one level deep and clearly signaled. Navigation is easy and nothing that belongs in a separate file is inlined, so it sits at the 5 anchor rather than 4's 'minor organization gaps'.

Specificity

The description names its domain ('adding a public teaching example or a docs tutorial') but offers no breakdown of the concrete actions involved (generating the app, slimming it, writing the tutorial page, wiring nav/config), placing it at 'domain plus 1-2 actions, not comprehensive'. It is above a 2 because 'adding a public teaching example' is a concrete, specific action rather than a generic one, but below a 4 because no multi-action capability list is present.

Completeness

It explicitly answers what ('adding a public teaching example or a docs tutorial') and when ('Use when adding a public teaching example or a docs tutorial'), with concrete trigger phrasing plus explicit negative triggers ('Don't use for an internal Nx playground..., a package API change with no walkthrough, or a docs-only copy edit'). This matches the 5 anchor on both explicit what and when with concrete triggers; a 4 would require the when to be less specific than it is.

Trigger Term Quality

Natural user phrases like 'adding a public teaching example', 'docs tutorial', and 'walkthrough' are present and would match how a user asks for this. A 5 would require broader synonym/extension coverage (e.g., 'guide', 'how-to', 'sample app'), and it is clearly above 3 because several common natural terms are already covered.

Distinctiveness Conflict Risk

The description actively disambiguates against three named sibling scenarios (internal Nx playground → new-react-playground, package API change without walkthrough, docs-only copy edit), giving it a clear niche with minimal conflict risk. It is not a 4 because no overlap risk remains unspecified — the exclusions cover the plausible confusions directly.
