## Symptom
Following the Assistants -> Responses migration guide, an agent recreates each Assistant as a dashboard prompt and calls `client.responses.create(prompt={"id": "pmpt_123"}, ...)`. This works today but is on a removal schedule.

## Cause
On 2026-06-03 OpenAI deprecated reusable prompt objects. Prompt creation is de-emphasized in the platform, and the `v1/prompts` API and reusable prompt objects are scheduled to shut down on 2026-11-30.

## Fix
Keep prompt content in application code (version it in git):
```python
INSTRUCTIONS = open("prompts/support_agent.md").read()
resp = client.responses.create(model=MODEL, instructions=INSTRUCTIONS,
    tools=TOOLS, input=user_input, conversation=conv_id)
```
Note `previous_response_id` does not carry over top-level `instructions`, so resend them on every request.

## Verify
`grep -rn 'pmpt_' .` is empty; no calls to `/v1/prompts`.
