Overview

The Prompt System manages dynamic prompt templates that control AI instructions and behavior. It supports protocol-based prompts, prompt composition, and various prompt types for different use cases.

---

Key Features

• Database-Stored Templates - Dynamic prompt management
• Protocol-Based Prompts - Context-aware prompts
• Prompt Composition - Multi-part prompt assembly
• Analyze Layer Prompts - Specialized analysis prompts
• Tool Calling Prompts - Tool execution prompts
• Identity Pack Layering - Stable core identity + protocol-safe expression rules

Identity Pack v1 (Runtime Contract)

Identity behavior is now a first-class prompt layer and is not delegated to ad-hoc protocol prose.

• Canonical identity source: backend/src/config/identityPack.ts
• Runtime assembly location: backend/src/services/aso/promptBuilder.service.ts
• Layering order:
  • SYSTEM CORE
  • PROTOCOL RULES
  • RUNTIME DIRECTIVES (includes Identity Contract block)
  • RUNTIME CONTEXT
  • AVAILABLE TOOLS
• Scope controls:
  • identity:off / identity:on
  • identity:allow_generic_self_reference
  • identity:chinatsu_anchor_on / identity:chinatsu_anchor_off

For production routing protocols, treat identity scope flags as policy configuration (via protocol scope) rather than code edits.
