There's no built-in bulk update for system prompts currently, but here's a breakdown of your questions:

1. Official bulk update? — No, RAGFlow doesn't have a native bulk update endpoint for chat assistant prompts.

2. Global/default system prompt? — There is a default system prompt applied to newly created chats, but it's hardcoded in the source code (_DEFAULT_PROMPT_CONFIG) rather than exposed as a configurable setting [1]. There's no admin panel or config file to change it globally.

3. API-based workaround? — Yes, this is the recommended approach. You can use:

• GET /api/v1/chats to list all chats [2]
• PATCH /api/v1/chats/<chat_id> to update each one [3]

The PATCH endpoint does a merge, so you only need to send the fields you want to change — existing prompt_config fields are preserved [4]:

# Example using the REST API
import requests

API_KEY = "your-api-key"
BASE_URL = "http://your-ragflow-host/api/v1"
headers = {"Authorization": f"Bearer {API_KEY}"}

# List all chats
chats = requests.get(f"{BASE_URL}/chats", headers=headers).json()["data"]["chats"]

# Bulk update
new_prompt = "Your new system prompt here. {knowledge}"
for chat in chats:
    requests.patch(
        f"{BASE_URL}/chats/{chat['id']}",
        headers=headers,
        json={"prompt_config": {"system": new_prompt}}
    )

4. Future plans? — I didn't find any active feature requests or roadmap items for batch prompt updates. Opening a feature request for this seems reasonable — there's clear demand based on similar user discussions [5].

One thing to note: make sure your new system prompt includes the {knowledge} placeholder if you want retrieval-augmented answers, as it's used to inject knowledge base context.
