What it does

Crowdin API Client is an agent skill from crowdin/crowdin-cli. Use when implementing, refactoring, or reviewing @crowdin/crowdin-api-client usage in any JavaScript or TypeScript project, especially for endpoint selection, request/response typing, pagination, uploads, retries, timeouts, or CrowdinError handling.

Its SKILL.md is about 1.1k 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 Development, covering Third-party API integration and Refactoring. It works with JavaScript and TypeScript. The repository describes itself as: A command-line client for the Crowdin API. The licence is MIT.

When your agent uses it

Reviewing @crowdin/crowdin-api-client usage in any JavaScript
TypeScript project
Especially for endpoint selection
Request/response typing

Example prompts

“/crowdin-api-client”

Requirements

A credential in CROWDIN_TOKEN

Workflow steps

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

Check local declarations first: node_modules/@crowdin/crowdin-api-client/out//index.d.ts.
Confirm exact API class and method name in use.
Confirm request model type and required fields.
Confirm response envelope: ResponseList or ResponseObject.

What it can do on your machine

Read from SKILL.md and the folder at commit 22a296c. 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 (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- crowdin.github.io
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- CROWDIN_TOKEN
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Crowdin API Client loads about 1.1k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 360 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
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

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.

Crowdin API Client

Overview

Use this skill when touching Crowdin API integration code in any project that depends on @crowdin/crowdin-api-client. Core principle: verify local client typings first, then implement with strict model types and correct response envelope handling.

When to Use

New or changed calls to @crowdin/crowdin-api-client.
Compile/type errors after API-client upgrades.
Confusion about method names, request fields, or ResponseList vs ResponseObject.
Refactors involving uploads, file translations, screenshots, tasks, comments, strings, or projects.
Reviews where behavior works at runtime but types/mapping look suspicious.

Do not use this skill for unrelated infra-only changes.

Required Preflight (Before Editing)

Check local declarations first: node_modules/@crowdin/crowdin-api-client/out/<module>/index.d.ts.
Confirm exact API class and method name in use.
Confirm request model type and required fields.
Confirm response envelope: ResponseList<T> or ResponseObject<T>.

Do not code from memory when typings and docs disagree.

Quick Reference

Scenario	Preferred Pattern
Multi-module flow	`new Client(credentials, options)` and destructure needed APIs
Single narrow flow	Direct module API class is acceptable
Full collection reads	`.withFetchAll()`
Transient failures	`retryConfig`
Bounded request duration	`{ httpRequestTimeout: 60_000 }`
Uploads	`uploadStorageApi.addStorage` -> `sourceFilesApi.createFile`
Error branching	`CrowdinValidationError` before `CrowdinError`

Core Patterns

Bootstrap

import { Client, Credentials } from '@crowdin/crowdin-api-client';

const credentials: Credentials = {
  token: process.env.CROWDIN_TOKEN!,
  organization: process.env.CROWDIN_ORG,
};

const client = new Client(credentials);

Response Envelope Handling

const listResponse = await client.tasksApi.withFetchAll().listTasks(projectId, options);
const tasks = listResponse.data.map((entry) => entry.data); // ResponseList<T>

const createResponse = await client.tasksApi.addTask(projectId, request);
const task = createResponse.data; // ResponseObject<T>

Typed Request Models

const request: TasksModel.CreateTaskRequest = {
  title: 'My Task',
  languageId: 'de',
  type: 0,
  fileIds: [12],
};

Error Handling

import { CrowdinError, CrowdinValidationError } from '@crowdin/crowdin-api-client';

try {
  // API call
} catch (error) {
  if (error instanceof CrowdinValidationError) throw error;
  if (error instanceof CrowdinError) throw error;
  throw error;
}

Common Mistakes

Mistake	Fix
Guessing endpoint methods from memory	Validate in local `index.d.ts` first
Treating list response as object response	Check `ResponseList<T>` vs `ResponseObject<T>` and map accordingly
Weakening or bypassing model typing	Use client `*Model` types in service signatures and fixtures
Manual pagination loops by default	Prefer `.withFetchAll()` unless custom batching is required
Uploading file directly to `createFile`	Create storage first, then pass `storageId`
Catching all errors as generic	Branch `CrowdinValidationError` and `CrowdinError` explicitly

Verification Gate

After changing API-client usage:

Run lint/type checks in the current project.
Run at least one targeted test for the modified API flow.
If tests fail on strict typing, fix fixture/model typing instead of loosening production types.

Review Checklist

Correct API module and method for the task.
Request models are explicit and include required fields.
Response mapping matches envelope shape.
Type safety is preserved without bypassing model contracts.
Pagination strategy matches expected volume.
Retry/timeout/runtime options fit environment.
Error handling distinguishes validation from generic API errors.
