custom-first-control-prompt

What it solves

• Allows inserting custom system prompt fragments in DSH, rendered in specified order before the deployment persona
• Supports injecting reference conversation history (alternating user/assistant messages) into every ordinary conversation request
• Maintains prefix cache reuse with byte-identical static content on every request

Who it’s for

• Developers who need to customize DSH system prompt structure
• Users who want to inject reference conversation history to influence model behavior
• Advanced DSH users who need fine-grained control over prompt assembly order
