I18n Lang Files

What it does

When your agent uses it

• Adding UI strings
• A merge conflicts in the lang files
• Deciding where a translation belongs

Example prompts

• “/i18n-lang-files”

Requirements

• Python 3

Workflow steps

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

1. 1Append in one block, at the end, in one commit. Cheap and immediate. It does
2. 2Sort the files alphabetically, once. This is the real fix: insertions scatter

What it can do on your machine

Read from SKILL.md and the folder at commit 6048fac. 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

  Ships script files (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python3
  • git

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

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  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

I18n Lang Files loads about 1.1k tokens when it runs. Until then it costs about 81 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

~81

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

~1.1k

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

Editing or merging backend/lang/en.json and pl.json. Use when adding UI strings, when a merge conflicts in the lang files, or when deciding where a translation belongs. Covers why these files conflict on every merge and how to resolve one without silently resurrecting a deleted key or breaking en/pl parity.

# from the repository root, while the merge is conflicted
python3 .claude/skills/i18n-lang-files/resolve-lang-conflict.py --check   # dry run
python3 .claude/skills/i18n-lang-files/resolve-lang-conflict.py           # write
git add backend/lang/*.json

python3 - <<'PY'
import json
en = json.load(open('backend/lang/en.json', encoding='utf-8'))
pl = json.load(open('backend/lang/pl.json', encoding='utf-8'))
print('en', len(en), 'pl', len(pl))
print('missing from pl:', sorted(set(en) - set(pl))[:10])
print('missing from en:', sorted(set(pl) - set(en))[:10])
print('untranslated:', [k for k, v in pl.items() if v == k][:10])
