What it does

API Endpoint Scaffolder is an agent skill from OneWave-AI/claude-skills. Generate REST API endpoints with proper structure, validation, error handling, and types. Use when creating new API routes, endpoints, or backend services.

Its SKILL.md is about 640 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 Backend & APIs, covering REST APIs. The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.

When your agent uses it

  • Creating new API routes
  • Backend services

Example prompts

  • “/api-endpoint-scaffolder”

Workflow steps

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

  1. Identify the framework (Express, Next.js, FastAPI, etc.)
  2. Determine HTTP method (GET, POST, PUT, PATCH, DELETE)
  3. Define request/response types
  4. Implement with best practices

What it can do on your machine

Read from SKILL.md and the folder at commit fc5b785. 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

    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

API Endpoint Scaffolder loads about 640 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 104 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~640

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.

API Endpoint Scaffolder

Instructions

When creating a new API endpoint:

  1. Identify the framework (Express, Next.js, FastAPI, etc.)
  2. Determine HTTP method (GET, POST, PUT, PATCH, DELETE)
  3. Define request/response types
  4. Implement with best practices

Templates

Next.js App Router (TypeScript)
typescript
// app/api/[resource]/route.ts
import { NextRequest, NextResponse } from 'next/server';
import { z } from 'zod';

const RequestSchema = z.object({
  // Define your schema
});

export async function GET(request: NextRequest) {
  try {
    const { searchParams } = new URL(request.url);
    // Implementation
    return NextResponse.json({ data }, { status: 200 });
  } catch (error) {
    console.error('[API] Error:', error);
    return NextResponse.json(
      { error: 'Internal server error' },
      { status: 500 }
    );
  }
}

export async function POST(request: NextRequest) {
  try {
    const body = await request.json();
    const validated = RequestSchema.parse(body);
    // Implementation
    return NextResponse.json({ data }, { status: 201 });
  } catch (error) {
    if (error instanceof z.ZodError) {
      return NextResponse.json(
        { error: 'Validation failed', details: error.errors },
        { status: 400 }
      );
    }
    return NextResponse.json(
      { error: 'Internal server error' },
      { status: 500 }
    );
  }
}
Express (TypeScript)
typescript
import { Router, Request, Response, NextFunction } from 'express';
import { z } from 'zod';

const router = Router();

const CreateSchema = z.object({
  // Define schema
});

router.post('/', async (req: Request, res: Response, next: NextFunction) => {
  try {
    const data = CreateSchema.parse(req.body);
    // Implementation
    res.status(201).json({ success: true, data });
  } catch (error) {
    next(error);
  }
});

export default router;

Best Practices

  1. Always validate input using Zod, Yup, or similar
  2. Use proper HTTP status codes:
    • 200: Success
    • 201: Created
    • 400: Bad Request
    • 401: Unauthorized
    • 403: Forbidden
    • 404: Not Found
    • 500: Server Error
  3. Log errors but don't expose internals to clients
  4. Use consistent response format
  5. Add rate limiting for public endpoints
  6. Document with OpenAPI/Swagger when possible
