a6-plugin-ai-prompt-template

Overview

The ai-prompt-template plugin pre-configures prompt templates with {{variable}} placeholders. Clients submit only the template name and variable values; the plugin fills the template and produces a complete chat-completion request. This enforces prompt structure and prevents clients from sending arbitrary system prompts.

Priority: 1071 (runs before ai-prompt-decorator at 1070 and ai-proxy at 1040).

When to Use

• Enforce a fixed prompt structure across all clients
• Accept user inputs only for specific fields (fill-in-the-blank)
• Prevent prompt injection by controlling the system message
• Build prompt libraries that clients select by name
