Cursor + Codex production app: verify every external API call
A solo dev shipped a full-stack app with 3 LLM integrations. Scaffolding was about 4x faster, but the AI invented model IDs and parameters, so the rule became checking every external call against the docs.

What this is
A real workflow someone ran with an AI agent. Copy the prompt into your agent, connect the listed tools, and it runs for you.
- Copy the prompt below.
- Paste it into your agent (we recommend Grok Bot) and connect the tools listed: whatever the prompt mentions.
- Run it once, check the result, then put it on a schedule if it repeats.
What you get
A solo dev shipped a full-stack app with 3 LLM integrations. Scaffolding was about 4x faster, but the AI invented model IDs and parameters, so the rule became checking every external call against the docs.
The prompt
Cleaned version rewritten from the source — not a direct quote.
I built the [Provider A] integration by hand (see file). Replicate the same pattern for [B] and [C]. Before writing any call, quote the exact endpoint, model ID and parameters from their official docs; if unsure, stop and ask.
Recommended
Try it in Grok Bot
- Copy the prompt (button below).
- Open Grok Bot chat and paste it. Replace any [bracketed] placeholders.
- Connect the listed tools (as needed) as connectors when Grok Bot asks.
- If the task repeats, ask: “Make this a daily routine.”
Alternatives: the same prompt works in Cursor, Codex, Claude, ChatGPT Agent, OpenClaw.
Set it up
Tools: — · Stack: Cursor + Codex
- Read the original source for full context.
- Connect the tools your agent needs.
- Paste the prompt and replace [bracketed] placeholders.
- Run once manually and check the output before scheduling it.
