Frappe Core Translation

What it does

When your agent uses it

• Implementing translations/i18n in Frappe v14-v16 apps
• Tasks that involve Translation
• Tasks that involve Internationalization

Example prompts

• “/frappe-core-translation”

Requirements

• Python 3
• Compatibility (from SKILL.md): Claude Code, Claude.ai Projects, Claude API. Frappe v14-v16.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Write translatable strings using _() / __() with positional placeholders
2. 2Extract untranslated strings
3. 3Translate the extracted strings (manually or via PO editor)
4. 4Place translations
5. 5Compile (v15+ PO only): bench compile-po-to-mo --app {app}
6. 6Clear cache: bench --site {site} clear-cache

What it can do on your machine

Read from SKILL.md and the folder at commit 36cfa80. 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 (its code samples are csv, bash, python and javascript).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  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.

• Compatibility

  Claude Code, Claude.ai Projects, Claude API. Frappe v14-v16.

  From compatibility in the SKILL.md frontmatter.

Context cost

Frappe Core Translation loads about 1.9k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 148 tokens; SKILL.md has 536 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~148

When it runs · the whole SKILL.md, loaded when a task matches

~1.9k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~7.8k

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

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.

description

Use when implementing translations/i18n in Frappe v14-v16 apps. Covers _() in Python, __() in JavaScript, CSV translation files, bench commands, string extraction rules, lazy translation _lt(), PO/MO files [v15+], RTL support, and custom app translations. Prevents common mistakes with f-strings, concatenation, and template literals that break string extraction. Keywords: translation, i18n, _(), __(), _lt(), CSV, PO, gettext,, translate my app, multi-language, text not translated, wrong language, how to add translation. bench get-untranslated, RTL, localization.

Need to translate a string?
├── In Python (.py)?
│   ├── Inside a function/method → _("text {0}").format(val)
│   ├── Module-level constant [v15+] → _lt("text")
│   └── Module-level constant [v14] → define inside function or use lazy
├── In JavaScript (.js)?
│   └── ALWAYS → __("text {0}", [val])

Where do translations live?
├── v14 → apps/{app}/{app}/translations/{lang}.csv
├── v15+ → apps/{app}/{app}/locale/{lang}/LC_MESSAGES/{app}.po
└── User overrides → Translation DocType (highest priority)

Need to extract untranslated strings?
├── v14 → bench --site {site} get-untranslated {lang} {output}
└── v15+ → bench generate-pot-file --app {app}
