[erunion]

🧰 Changes

Adds a new ai target and prompt client for generating copy-and-pastable prompts for any AI model (ChatGPT, Claude, etc.) that asks the model to write code that makes the described HTTP request.

🧬 QA & Testing

This is what it looks like:

Write code that makes the HTTP request described below. Use my preferred programming language and HTTP client library — if I haven't told you what those are, ask me before writing any code.

Method: POST
URL: https://httpbin.org/anything?foo=bar

Headers:
  content-type: application/json

Body (application/json):
{"foo":"bar"}

The request the code makes must match the method, URL, headers, and body exactly as described above.

And when the client target is supplied a markdownURL:

Write code that makes the HTTP request described below. Use my preferred programming language and HTTP client library — if I haven't told you what those are, ask me before writing any code.

Method: GET
URL: https://httpbin.org/anything

The request the code makes must match the method, URL, headers, and body exactly as described above.
