i18n-localization
i18n-localization is a skill in alirezarezvani/claude-skills, last changed 2 Nov 2026. It can run shell commands, name web addresses and bundle scripts.
Use when adding UI text, adding or shipping a language, reviewing translation files, or building i18n into an app. Checks missing keys, placeholders and CLDR plural forms with locale_sync.py, finds hardcoded strings with hardcoded_strings.py, and builds a pseudo-locale with pseudo_localize.py.

Pattern check
Pattern check: 1 item to review · commit 7f92eda · 3 Nov 2026
We checked every text file in this skill, at commit 7f92eda on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specPasses with warnings
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.
- Warning
Fields outside the spec: argument-hint (read by Claude Code and VS Code). Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1
Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.
- Warning
- Claude CodePasses
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
Upload and packaging fail on fields outside the spec: argument-hint. O1
Fix: Delete them, and keep your own data under metadata as text values.
- Note
The description is 294 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Error
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
Fields outside the spec: argument-hint. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1
Fix: Delete them, or move your own data under metadata as text values.
- Warning
- VS Code & CopilotPasses
