Produce a GPT prompt that, when pasted into a chat model, generates a polished architecture or workflow diagram image. Write the prompt to a file. Keep chat output to the file path only.

Output Discipline

When this skill fires:

1. Write the full prompt to ~/diagram-prompts/<slug>.md. Create the directory if missing. <slug> is short kebab-case inferred from the topic.
2. The file content must be the prompt and nothing else.
3. The chat reply must be exactly:

Prompt -> /home/arthur/diagram-prompts/<slug>.md
Open the file, copy all, paste into GPT.

4. Do not echo the prompt body back into chat after writing it.
