Conciseness

Code-first and lean throughout: every section is a compact executable snippet or a terse bullet list ('Never concatenate translated strings'), with only intent-clarifying comments ('// "yesterday"'). No explanations of concepts Claude already knows, matching anchor 5's 'every token earns its place'.

Actionability

Mostly executable, copy-paste-ready guidance: complete i18next init with inline resources, pluralization keys with usage, Intl.DateTimeFormat/NumberFormat/RelativeTimeFormat, and logical CSS properties. Minor gaps keep it at anchor 4 rather than 5: no install commands and the i18next usage snippet mixes module-level init with component-level useTranslation().

Workflow Clarity

A cookbook-style skill with self-contained, unambiguous sections and no destructive/batch operations requiring validation. It fits anchor 4 rather than 5 because it offers no decision guidance for choosing among the three named frameworks (i18next vs gettext vs Intl) and has no overarching process flow.

Progressive Disclosure

The main file holds getting-started recipes while bulk advanced content is split into one clearly signaled, one-level-deep reference; the bullet list under 'See references/frameworks.md' accurately describes the file's actual sections (React-Intl, Python gettext with Flask/Babel, RTL patterns, ICU Message Format) and the reference contains no nested links, matching anchor 5.

Specificity

Names concrete tools ('i18next, gettext, or Intl API') and several capability areas ('translation workflows and RTL support', 'date/currency formatting'), matching anchor 4's 'several specific actions; minor gaps'. Not 5 because 'Implements multi-language support' is broader and less enumerated than anchor 5's list of concrete actions; not 3 because coverage exceeds 1-2 actions.

Completeness

Explicitly answers both: what ('Implements multi-language support using i18next, gettext, or Intl API with translation workflows and RTL support') and when ('Use when building multilingual applications, handling date/currency formatting, or supporting right-to-left languages') with concrete trigger phrases, matching the anchor 5 example pattern.

Trigger Term Quality

Includes natural phrases users would say: 'multi-language', 'multilingual applications', 'translation', 'date/currency formatting', 'right-to-left languages'. Good coverage but missing common synonyms like 'localization', 'l10n', 'i18n', or 'translate strings', so it fits anchor 4 rather than 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Clear i18n niche with distinct triggers (translation, RTL, multilingual), but 'date/currency formatting' is a broadly shared trigger that could overlap with formatting-related skills, fitting anchor 4 ('mostly distinct; minor overlap risk') rather than 5's minimal conflict risk.
