What it does
Pluralization is an agent skill from thedaviddias/Front-End-Checklist. Use when reviewing string concatenation involving counts, translation key lookups, or i18n library configurations to check whether plural forms are handled correctly for all target locales.
Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).
It sits in Frontend & Design, covering Translation and Internationalization. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.
When your agent uses it
- Reviewing string concatenation involving counts
- Translation key lookups
- I18n library configurations to check whether plural forms are handled correctly for all target locales
Example prompts
- “/pluralization”
What it can do on your machine
Read from SKILL.md and the folder at commit e8d14d0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
frontendchecklist.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Pluralization loads about 553 tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 51 tokens; SKILL.md has 242 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Handle plural forms with Intl.PluralRules or ICU MessageFormat
Pluralization rules vary dramatically across languages — what works as a simple singular/plural branch in English produces grammatically wrong output in Arabic, Russian, Polish, and dozens of other languages. Shipping incorrect plurals signals low translation quality and breaks trust with native speakers in target markets.
Quick Reference
- English has 2 plural forms but Arabic has 6 and Russian has 3
- Never concatenate a count with a string like '"You have " + count + " items"'
- Use Intl.PluralRules to select the right message key per locale
- ICU MessageFormat in react-intl or i18next handles plural selection automatically
Check
Find all places in this codebase where a count value is concatenated with a string or where only singular/plural branching is used, without Intl.PluralRules or ICU plural syntax.
Fix
Replace count string concatenation and binary singular/plural logic with Intl.PluralRules-based key selection or ICU MessageFormat plural syntax so that all CLDR plural categories are covered for every target locale.
Explain
Explain why languages have different numbers of plural forms, what CLDR plural categories are, and how Intl.PluralRules and ICU MessageFormat solve pluralization correctly across locales.
Code Review
Review translation files and components that render counts. Flag any strings that concatenate a number with text, any ternary that picks only between "singular" and "plural", and any i18next or react-intl message that is missing plural keys required by the target locale.
