generate_api_tests_from_swagger

A workflow that reads a Swagger or OpenAPI document, which describes an API's available endpoints and data rules, and creates API test cases. It can also produce automation scripts.

In plain words
What is it for?
Use it to create documented API test cases and test-data matrices, or generate the corresponding automation code.
Why use it?
It saves time when checking many API endpoints and avoids inventing endpoints or request formats that are not in the specification.

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.

Token cost

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.

Security

Grade A, and why

generate_api_tests_from_swagger scanned grade A with 0 findings 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 3d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Command: Sinh API Tests từ Swagger/OpenAPI

BẮT BUỘC (MANDATORY SKILL): Bạn PHẢI nạp và đọc kỹ nội dung của skill skills-qa-automation-engineer (tại .claude/skills/skills-qa-automation-engineer/SKILL.md) trước khi bắt đầu. Ngoài ra, tham khảo thêm skill skills-test-data-generator để sinh test data đúng chuẩn.

Command này giúp agent phân tích Swagger/OpenAPI specification, xác định các endpoints, sinh API test cases có cấu trúc, và (tùy mode) tự động sinh automation scripts hoàn chỉnh.

⚠️ Nguyên tắc thực thi

  • Tất cả output bằng Tiếng Việt
  • KHÔNG đoán schema/endpoint — phải đọc spec thực tế (JSON/YAML)
  • Phải chờ user xác nhận scope tại Bước 2 trước khi sinh chi tiết
  • Nếu user chưa cung cấp Swagger URL/file → hỏi trước khi bắt đầu
  • ⚠️ Rule E3: Khi test FAIL → tự đọc log → phân tích → sửa → chạy lại. KHÔNG hỏi user trong quá trình fix lỗi

2 Chế độ (Mode)

Mode Khi nào sử dụng Output
SPEC (mặc định) User cần API test cases dưới dạng tài liệu API Test Cases (Markdown) + Test Data Matrix
FULL User yêu cầu cả automation scripts Như SPEC + Automation Scripts + Project Structure

Nếu user nói "generate automation", "viết code test API", hoặc yêu cầu scripts → tự động chuyển sang Mode FULL.

Các bước thực hiện

Bước 1: Tiếp nhận & Phân tích Spec (Parse & Analyze)

  1. Thu thập Swagger/OpenAPI spec từ user:
    • URL trực tiếp (VD: https://api.example.com/swagger.json) → dùng WebFetch để fetch
    • File local (JSON/YAML) → dùng Read để đọc
    • Swagger UI URL → trích xuất URL spec gốc (thường là /v2/api-docs hoặc /v3/api-docs)
    • Scalar API Reference URL → inspect HTML để tìm data-configuration chứa URL spec (thường là /swagger/json, /reference/json, hoặc relative path trong attribute url). VD: https://book.anhtester.com/swagger → spec tại https://book.anhtester.com/swagger/json
    • Các dạng API Doc khác (Redoc, Stoplight, RapiDoc) → tìm URL spec trong page source hoặc network requests
  2. Parse spec và trích xuất thông tin:
    • Base URL, API version, authentication scheme (Bearer, API Key, OAuth2, Basic)
    • Danh sách tất cả endpoints: method + path
    • Request parameters: path, query, header, body (schema + required fields)
    • Response schemas: status codes, response body structure
    • Models/Definitions: reusable data models
  3. Phân loại endpoints theo nhóm:
    • CRUD operations — Create, Read, Update, Delete
    • Authentication — Login, Register, Token refresh
    • Business Logic — Các API xử lý nghiệp vụ phức tạp
    • Utility — Health check, config, metadata

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.
