What it does

Library Sync is an agent skill from glebis/claude-skills. Sync and manage bilingual (EN/RU) library content for agency-docs. Use when adding, updating, or reviewing library articles. Handles translation, sync checks, and Russian stylistic review.

Its SKILL.md is about 800 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 Writing & Content, covering Translation. It works with Git. The repository describes itself as: Collection of Claude Code skills for enhanced AI workflows. The licence is MIT.

When your agent uses it

  • Reviewing library articles
  • Tasks that involve Translation

Example prompts

  • “/library-sync”

Workflow steps

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

  1. Create the article in English first at content/docs/library/en/.mdx
  2. Translate to Russian at content/docs/library/ru/.mdx
  3. Add to both meta.json files in the appropriate section
  4. Run Russian stylistic review
  5. Verify both render correctly

What it can do on your machine

Read from SKILL.md and the folder at commit 7524dff. 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

    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

Library Sync loads about 798 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 319 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~798

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.

Library Sync Skill

Manages the bilingual library at ~/Sites/agency-docs/content/docs/library/ with English (en/) and Russian (ru/) versions.

Commands

add <slug> — Add a new article to both languages
  1. Create the article in English first at content/docs/library/en/<slug>.mdx
  2. Translate to Russian at content/docs/library/ru/<slug>.mdx
  3. Add to both meta.json files in the appropriate section
  4. Run Russian stylistic review
  5. Verify both render correctly
sync — Check sync status between EN and RU
  1. List all files in en/ and ru/
  2. Report files missing in either language
  3. Compare frontmatter titles (ensure they match conceptually)
  4. Flag articles updated in one language but not the other (compare git timestamps)
translate <slug> <from> <to> — Translate an article
  1. Read the source article
  2. Translate to target language
  3. Adapt examples and links for the target audience
  4. Run stylistic review if target is Russian
  5. Update meta.json
review-ru — Russian stylistic review

Run on all Russian library articles. Check for:

  • Consistency: same terms used throughout (not mixing Агент/Эйджент)
  • Natural Russian: not word-for-word translation from English
  • Technical terms: keep English terms where standard (Git, MCP, API, CLAUDE.md)
  • Links: internal links use /library/ru/ paths
  • Tone: educational but not condescending, informal "ты" address
update <slug> — Update an existing article in both languages
  1. Read the current version
  2. Apply changes to the primary language
  3. Sync changes to the other language
  4. Run Russian review if Russian was changed

Russian Style Guide

  • Use "ты" (informal), not "вы" (formal)
  • Keep technical terms in English: Git, API, MCP, CLAUDE.md, CLI, LLM, token
  • Transliterate only when a Russian term is well-established: агент, промт, токен
  • Don't translate code examples or command-line output
  • Adapt cultural references (e.g., currency examples: use both $ and ₽)
  • Cross-link to English version at the bottom: [English version](/library/en/<slug>)
  • Cross-link from English to Russian: [Русская версия](/library/ru/<slug>)

Meta.json Sections

Use ---SectionName--- separators in meta.json for nav grouping:

  • Modes / Режимы
  • Core Concepts / Ключевые концепции
  • Features / Возможности
  • Tools / Инструменты
  • Reference / Справочник
