Conciseness

The body is largely lean bullet-style guidance with no tutorials on concepts Claude already knows, but there is noticeable redundancy: the "Core Capabilities" section overlaps the workflow steps, and placeholder/plural guidance appears in both step 7 ("Keep placeholders consistent") and "Architecture Guidance" ("preserve {name}/{{name}} exactly"). This fits the efficient-with-minor-trimmable-instances anchor, not the every-token-earns-its-place anchor.

Actionability

Mostly executable: the audit invocation (`python scripts/i18n_audit.py --src ... --locale ...`), the two `rg` search commands, and `python -m json.tool` validation are concrete, with specific library picks and key patterns. Minor gaps remain — steps like "Wire the provider at the app root" and "Install packages" give direction without commands or snippets, keeping it below fully copy-paste-ready coverage.

Workflow Clarity

The Audit -> Fix -> Validate workflow is an explicitly sequenced 8-step process with a real feedback loop: step 8 says "Re-run the audit until missing/parity issues are zero", plus JSON validation and test updates. Validation checkpoints are explicit and the failure modes/checklist sections reinforce recovery, matching the top anchor — the batch string-replacement work is validated, so the destructive/batch cap does not apply.

Progressive Disclosure

Good structure: a well-organized single-file overview with the one bundle file (`scripts/i18n_audit.py`, verified to exist) referenced both in the workflow and in a Resources section, one level deep. It falls short of the top anchor because there are no reference files for the substantial inline guidance (architecture notes, search patterns), and a couple of sub-bullets are inconsistently indented (lines 43 and 123), slightly marring navigation.

Specificity

The description lists multiple concrete actions — "installing/configuring the i18n framework, replacing hard-coded strings, ensuring en-US/zh-CN coverage, mapping error codes to localized messages, and validating key parity, pluralization, and formatting" — giving comprehensive coverage of the domain. It matches the anchor for multiple specific concrete actions rather than the anchor 4 case, which would require noticeable coverage gaps.

Completeness

It explicitly answers both questions: the what is the concrete action list, and the when is the explicit trigger clause "This skill should be used when setting up, auditing, or enforcing internationalization/localization in UI codebases". Both are present with concrete trigger phrases, matching the top anchor rather than anchor 4 where the 'when' is only loosely specified.

Trigger Term Quality

Good keyword coverage: "internationalization/localization", "React/TS", "i18next", "JSON locales", "hard-coded strings", "en-US/zh-CN", "pluralization" are natural phrases a user would say. A few common variations are missing — the standalone abbreviation "i18n", "translations"/"translate", and generic "locale files" — so it falls just short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The i18n/localization niche is well defined with distinct triggers (locale parity, pluralization, hard-coded string replacement) and named technologies (i18next, JSON locales), so it is unlikely to fire for unrelated skills. Minimal conflict risk, matching the clear-niche anchor.
