What it does
Localization is an agent skill from yqlay/flclash-tui. Use when changing FlClash UI text, scanning for hardcoded Chinese strings, updating ARB localization, or fixing generated locale output in this repository.
Its SKILL.md is about 440 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design, covering Internationalization. It works with Dart. The repository describes itself as: Linux/SSH/headless Mihomo TUI. Default silent: only flc COMMAND uses the proxy. The licence is GPL-3.0.
When your agent uses it
- Changing FlClash UI text
- Scanning for hardcoded Chinese strings
- Updating ARB localization
- Fixing generated locale output in this repository
Example prompts
- “/localization”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- Confirm pubspec.yaml still uses flutter_intl, source ARBs under arb/, and generated output under lib/l10n/.
- Scan user-facing Dart text before opening many files
- Inspect the smallest relevant call sites and nearby ARB keys.
- Add or update every source ARB
- Replace inline strings with existing project accessors
- Regenerate
- Verify changed Dart files with flutter analyze when practical.
- Re-run the Han-text scan for targeted strings.
What it can do on your machine
Read from SKILL.md and the folder at commit 89df3cf. 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
Shell commands in SKILL.md call:
rgdartflutter
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.
Context cost
Localization loads about 440 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 176 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.

Localization
When To Use
Use this for localization work inside /Users/Shared/follow/FlClash, especially hardcoded UI text in lib/, ARB updates, missing translations, or generated lib/l10n/ output that does not match source ARB values.
Do not use this for README translation sync or manual edits to generated localization Dart.
Workflow
Confirm
pubspec.yamlstill usesflutter_intl, source ARBs underarb/, and generated output underlib/l10n/.Scan user-facing Dart text before opening many files:
bash rg -n "[\\p{Han}]" lib -g '!lib/l10n/intl/**' -g '!lib/**/generated/**'Inspect the smallest relevant call sites and nearby ARB keys.
Add or update every source ARB:
arb/intl_en.arbarb/intl_zh_CN.arbarb/intl_ja.arbarb/intl_ru.arb
Replace inline strings with existing project accessors:
- Widgets with
BuildContext:context.appLocalizations.keyfromcommon.dart. - Controllers/providers/non-widget code:
currentAppLocalizations.keyfromapp_localizations.dart.
- Widgets with
Regenerate:
bash dart run intl_utils:generateVerify changed Dart files with
flutter analyzewhen practical.Re-run the Han-text scan for targeted strings.
Pitfalls
- If ja/ru still show English, fix ja/ru source ARB values and regenerate. Do not edit generated Dart.
- Ignore
lib/l10n/intl/**andlib/**/generated/**during text scans. - If generator or analyzer hits local cache permission friction, rerun serially before treating it as a code issue.

Questions about Localization
What does Localization do?
A skill your agent uses when changing FlClash UI text, scanning for hardcoded Chinese strings, updating ARB localization, or fixing generated locale output in this repository. Localization is an agent skill from yqlay/flclash-tui. Use when changing FlClash UI text, scanning for hardcoded Chinese strings, updating ARB localization, or fixing generated locale output in this repository.
When should I use Localization?
Localization fits situations like: changing FlClash UI text; scanning for hardcoded Chinese strings; updating ARB localization; fixing generated locale output in this repository.
How do I install Localization in Claude Code?
Run `npx skills add yqlay/flclash-tui --skill localization -a claude-code`. Or copy the skill folder (.agents/skills/localization in yqlay/flclash-tui) into .claude/skills/localization in your project. Claude Code loads it when a task matches its description.
How do I install Localization in Codex?
Run `npx skills add yqlay/flclash-tui --skill localization -a codex`. Or copy the skill folder (.agents/skills/localization in yqlay/flclash-tui) into .agents/skills/localization in your project. Codex loads it when a task matches its description.
Can I use Localization in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add yqlay/flclash-tui --skill localization -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/localization, .gemini/skills/localization, .github/skills/localization and .opencode/skills/localization in your project.
What does Localization need to run?
Going by SKILL.md and its folder, Localization needs the command-line tools its instructions call (rg, dart and flutter).
Does Localization access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Localization safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Localization use?
Localization is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Localization use?
About 440 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Localization?
