Conciseness

Every line is an instruction or a repo-specific fact ('Inline the model id', 'Do not add `@tanstack/ai-client` (framework packages re-export the client)'), with zero concept explanations or padding — a direct match to anchor 5, 'every token earns its place'. Not 4 because there are no over-explanatory passages to trim.

Actionability

Guidance is copy-paste ready: the generator command (`pnpm nx g @tanstack/workspace-plugin:react-app <slug>`), exact file paths, config keys, the sandbox comment literal, and the GitHub link URL pattern. Anchor 5's 'specific examples cover the common cases' is met by the End state list and install-line spec; only trivial placeholders (<slug>) remain, which is appropriate.

Workflow Clarity

A clear, well-ordered sequence (shape the app → file layout → tutorial page → nav and pointers → PRs) is capped by an explicit 'End state' checklist, and the Common mistakes table acts as error-recovery guidance. It falls short of anchor 5 only because there is no interim validation step (e.g., build or run the example and verify tutorial code matches before opening the PR) — anchor 4's 'minor validation gaps'.

Progressive Disclosure

A single self-contained file with clear section headers, numbered steps, and a mistakes table — no nested references and nothing that clearly belongs in a separate file. It matches anchor 4 ('good structure, appropriately placed content') rather than 5 because at ~90 lines it exceeds the under-50-line single-file ideal and slightly overlaps sections (PR rules appear both in 'End state' and a separate 'PRs' section).

Specificity

The description names a specific domain ('adding a public teaching example or a docs tutorial') with one generic action ('adding'), but states none of the concrete capability actions the skill performs (generating the app, writing the tutorial, wiring nav, opening a PR). It matches anchor 3 — domain plus 1-2 concrete actions, not comprehensive — rather than 4, which requires several specific actions.

Completeness

The 'when' is explicit and specific ('Use when adding a public teaching example or a docs tutorial'), and a 'what' is present but thin — the task context implies the work without stating the capability actions. Both exist with one weaker side, matching anchor 4; it is not 5 because the 'what' lacks concrete capability phrases.

Trigger Term Quality

Natural phrases a user would say are present ('adding a public teaching example', 'docs tutorial', 'Nx playground', 'package API change', 'copy edit'), and the negative triggers double as disambiguating keywords. A few natural synonyms ('walkthrough', 'how-to', 'sample app') are missing, so it fits anchor 4 rather than 5.

Distinctiveness Conflict Risk

Explicit carve-outs name the sibling skill and excluded cases ('an internal Nx playground (that is new-react-playground)', 'a package API change with no walkthrough', 'a docs-only copy edit'), giving a clear niche with minimal conflict risk — a direct match to anchor 5.
