Golden prompt set for ChatGPT Apps
OpenAI Developer Community
May 31, 2026
I’ve been dealing with this while building Turnfeed. What helped most was separating prompts by intent level:
1. Direct invocation:
“Use Turnfeed to show me the most active threads.”
2. Natural task:
“What are people discussing recently?”
or
“Find a thread worth replying to.”
3. Public write boundary:
“Reply to Richard saying: Turnfeed sounds promising.”
4. Negative prompts:
“Draft a reply but don’t post it.”
“Summarize the thread.”
“Should I post this?”
For public-write apps, I think the golden set needs to test not only whether the tool triggers, but whether the model chooses the read-only tool first, avoids publishing when the user is ambiguous, and only uses the write tool when target + exact text + visibility are clear.
