Crowdin Skills

Crowdin Skills are instruction packages that teach an AI coding agent how to work with Crowdin. Once they are installed, the agent knows the Crowdin CLI commands, the configuration file format, the API client, and the query languages, so you can describe a localization task in plain language instead of looking up the syntax yourself.

Skills do not connect the agent to your Crowdin account. They work inside your development environment, next to your source code, unlike the Crowdin MCP Server.

Available Skills

Syncing content

• crowdin-cli – Syncing source files and translations between your project and Crowdin with Crowdin CLI v5.
• github-action – Setting up and debugging the crowdin/github-action step in a GitHub workflow.

Adding context to source strings

• context-extraction – Writing context for the source strings that need it.
• crowdin-context-cli – Working with the crowdin context commands and the JSONL format they use.

Working with project data

• crowdin-api-client – Using the JavaScript and TypeScript API client, including pagination, uploads, and error handling.
• croql – Writing and optimizing CroQL expressions for strings, translations, TM segments, and glossary terms.
• graphql – Writing and debugging Crowdin GraphQL queries against the actual schema.

Building apps

• create-app – Scaffolding, developing, and publishing a Crowdin app.

Installation

Skills work with Claude Code, Cursor, OpenAI Codex, Gemini CLI, GitHub Copilot, OpenCode, Cline, Windsurf, and other AI coding agents. Each client adds them in its own way, so follow the installation instructions in the repository.

Install Crowdin Skills

Once installed, the skills become available on their own when you work in a project that uses Crowdin or mention something they cover. You can also point your agent at them directly in a request.

Skills and the MCP Server

Skills and the Crowdin MCP Server both help an AI agent work with Crowdin, in different places.

• Crowdin Skills teach the agent how Crowdin’s developer tools work. The agent applies that knowledge locally, against your source code and your crowdin.yml.
• Crowdin MCP Server connects the agent to your Crowdin account, so it can read and change project data directly.

You can use both: Skills to run the right command in your repository, and the MCP Server to check the result in your project.
