Conciseness

The body is dense with project-specific facts (file paths, commands, naming rules, mistake tables) and never explains generic i18n concepts Claude already knows. Minor redundancy keeps it from a 5: the 'read i18n-config.json first / never assume a fixed number of languages' instruction is repeated in the intro, Step 1, Key Facts, the checklist, and the mistakes table.

Actionability

Fully executable throughout: concrete `cat`/`grep` commands, ordered `bun run i18n:types` then `node scripts/check-i18n.js` validation, copy-paste-ready TSX and JSON examples, and bad/good code pairs. The only trivial blemish is inconsistent path prefixes (`src/common/config/...` vs `packages/desktop/src/...`), which does not undermine executability.

Workflow Clarity

The 'Adding New Text' workflow is a clearly sequenced 6-step process with an explicit validation checkpoint (Step 6), error-recovery feedback ('If check-i18n.js exits with errors (❌), fix them before proceeding'), a hard gate ('Never commit with a stale i18n-keys.d.ts'), and a final checklist; the batch operation of adding keys to every locale is backed by a CI-validating script. This matches the anchor-5 example's validate-fix-retry pattern.

Progressive Disclosure

The skill is a single self-contained file with clear, well-ordered sections and no nested or buried references, and nearly all content is operationally relevant to the workflow rather than bulk reference material. It falls short of anchor 5 because at ~240 lines everything is inlined — reference-style content such as the zh-TW term-conversion table could live in a separate reference file with a well-signaled link.

Specificity

The description names the domain ("Internationalization (i18n) workflow and standards") but the only stated action is the generic "managing translations" — no concrete capabilities like adding keys to all locales, regenerating type definitions, or validating translations are listed. It matches anchor 2 ('names the domain but actions are minimal or generic') rather than 3, which requires 1-2 concrete actions.

Completeness

Both parts are present: a 'what' ("workflow and standards for managing translations") and an explicit numbered "Use when:" list with four triggers. Falls short of anchor 5 because the 'what' is high-level and lacks concrete capability statements.

Trigger Term Quality

Includes natural terms users would say: "Internationalization", "i18n", "translations", "user-facing text", and "i18n compliance". Not a 5 because common synonyms such as "localization", "locales", or "languages" are missing.

Distinctiveness Conflict Risk

The i18n/translation niche is clearly distinct with specific triggers ("Reviewing code for i18n compliance", "Adding a new translation module"). Minor overlap risk remains because "Creating new components with user-facing text" is broad enough to fire during general UI-component work.
