Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00141 | $0.01848 |
| Opus 5 | $0.00071 | $0.00924 |
| Sonnet 5 | $0.00028 | $0.00370 |
| Haiku 4.5 | $0.00014 | $0.00185 |
Grade A, and why
i18n-studio scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
i18n Studio
Purpose
i18n Studio edits Astro-style i18n string files safely: files shaped like
export default { en: {...}, ru: {...} } where leaves are UI strings. It writes
one string literal at a time through a ts-morph AST, so every save is a minimal
one-line diff with all surrounding formatting preserved, and a running dev server
hot-reloads. It also produces Claude translation candidates that preserve HTML
tags and tone.
Use it instead of hand-editing .ts string files with Edit/sed: manual edits
risk formatting churn, broken quoting/escaping, and desynced languages. The AST
layer avoids all three.
When to use
- Filling in missing translations for a language (e.g. "translate the new hero copy to Russian", "fill the German gaps").
- Auditing coverage ("which strings are untranslated?").
- Editing UI microcopy in one or more languages.
- Getting translation candidates for a specific string.
- Opening a visual editor for a human to translate interactively ("open the translation editor").
Applies to any repo whose translations follow the export default { <lang>: {...} }
convention, not one specific project.
Locate the strings directory first
The tool defaults to <cwd>/src/i18n/strings. Confirm the real location before
starting (it may differ):
ls src/i18n/strings 2>/dev/null || find . -path '*/i18n/strings' -type d -not -path '*/node_modules/*' | head
Use that path as --dir below. Ensure the tool is installed once:
cd ~/ai_projects/i18n-studio && npm install.
Start the server (required for the API and the UI)
Start it in the background, pointed at the target strings dir, and wait until it is reachable:
node ~/ai_projects/i18n-studio/server.mjs --dir "$PWD/src/i18n/strings" --port 4331 &
until curl -sf http://localhost:4331/api/strings >/dev/null; do sleep 0.5; done
Pass --langs en,ru,de if the corpus has languages beyond the en,ru default,
and --voice "<one-line tone brief>" to steer suggestion style. Stop it with
kill %1 (or the printed PID) when finished.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

i18n-studio is a skill published in the GitHub repository glebis/claude-skills (375 stars, last pushed 9d ago), licensed MIT. It adds 141 tokens to every session and 1,848 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
