a6-plugin-ai-prompt-decorator

Overview

The ai-prompt-decorator plugin prepends and/or appends messages to the client's messages array before forwarding to the LLM provider. Use it to inject system instructions, safety guidelines, or output format requirements without modifying client code.

Priority: 1070 (runs after ai-prompt-template at 1071, before ai-proxy at 1040).

When to Use

• Inject a system prompt on every request (e.g. safety guidelines)
• Append output format instructions (e.g. "respond in JSON")
• Add conversation context that clients should not control
• Combine with ai-prompt-template for structured + decorated prompts
