i18n-expert

This skill should be used when setting up, auditing, or enforcing internationalization/localization in UI codebases (React/TS, i18next or similar, JSON locales), including 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.

Content

62%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a well-structured skill with a strong workflow that follows the audit-fix-validate pattern with clear feedback loops. Its main weaknesses are the lack of executable code examples for core setup tasks (config files, provider wiring, locale file templates) and some verbosity in sections that describe concepts Claude already understands. The referenced audit script is not provided in the bundle, reducing the actionability of the audit steps.

Suggestions

Add a concrete, executable code example for i18n setup (e.g., a complete react-i18next config file and provider wiring snippet) to make step 2 actionable rather than descriptive.

Provide the referenced `scripts/i18n_audit.py` as a bundle file, or remove the reference and replace with an inline validation approach.

Include a sample locale file template (en-US.json / zh-CN.json) showing the expected key structure, plural forms, and placeholder conventions.

Trim or consolidate 'Core Capabilities', 'Architecture Guidance', 'Failure Modes', and 'Performance Notes' — much of this is general knowledge Claude already has; keep only project-specific conventions.

DimensionReasoningScore

Conciseness

The skill is reasonably efficient but includes some sections that over-explain things Claude already knows (e.g., 'Core Capabilities' listing generic concepts, 'Architecture Guidance' covering basics like namespace structure). Some sections like 'Failure Modes' and 'Performance Notes' add marginal value. The 'Scope Inputs' section is useful but could be tighter.

2 / 3

Actionability

The skill provides some concrete commands (ripgrep patterns, json validation, audit script invocation) but lacks executable code examples for the core setup tasks (no actual i18n config file example, no provider wiring code, no locale file template). The setup steps in section 2 are descriptive rather than executable. The referenced `scripts/i18n_audit.py` is mentioned but not provided in the bundle.

2 / 3

Workflow Clarity

The 8-step workflow is clearly sequenced with an explicit audit-fix-validate loop. Step 8 re-runs the audit until issues are zero, providing a clear feedback loop. Validation checkpoints are explicit (JSON validation, re-running audit, updating tests). The workflow handles the destructive operation of replacing strings with appropriate verification steps.

3 / 3

Progressive Disclosure

The skill references `scripts/i18n_audit.py` but no bundle files are provided, so the reference is unverifiable. The content is somewhat monolithic — sections like 'Architecture Guidance', 'Failure Modes', 'Performance Notes', and 'Validation Checklist' could be split into separate reference files. However, the overall organization with clear section headers is reasonable for the content volume.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a strong skill description that clearly defines its scope, lists concrete actions, and provides explicit trigger conditions. It covers both the 'what' and 'when' effectively, uses natural keywords that users would employ, and occupies a distinct niche that minimizes conflict risk with other skills.

DimensionReasoningScore

Specificity

Lists multiple specific concrete actions: installing/configuring i18n framework, replacing hard-coded strings, ensuring en-US/zh-CN coverage, mapping error codes to localized messages, validating key parity, pluralization, and formatting.

3 / 3

Completeness

Clearly answers both 'what' (installing/configuring i18n, replacing hard-coded strings, ensuring locale coverage, mapping error codes, validating key parity) and 'when' ('when setting up, auditing, or enforcing internationalization/localization in UI codebases') with explicit trigger guidance.

3 / 3

Trigger Term Quality

Includes strong natural keywords users would say: 'internationalization', 'localization', 'i18n', 'i18next', 'hard-coded strings', 'JSON locales', 'React/TS', 'en-US', 'zh-CN', 'pluralization', 'error codes'. Good coverage of both abbreviations and full terms.

3 / 3

Distinctiveness Conflict Risk

Highly distinctive niche focused on i18n/localization in React/TS codebases with i18next. The combination of specific technologies, locale pairs, and i18n-specific tasks makes it very unlikely to conflict with other skills.
