Relocate Input Guardrail Before Tool Classifier

[nuwangeek]

Description

Currently, the LLM Module has input guardrails only for the RAG workflow. Since we are adding a pre-step before all workflows (tool classifier), it is better to relocate the input guardrail to execute before the tool classifier.

Current Flow

User Query → Tool Classifier → [Service | Context | RAG] → Input Guardrails (RAG only)

Proposed Flow

User Query → Input Guardrails → Tool Classifier → [Service | Context | RAG]

Technical Requirements

8.1 Move Guardrail Execution

Current Location: Inside RAG workflow execution
New Location: Before tool classifier in main orchestration pipeline

Acceptance Criteria

• Move input guardrail check before tool classifier in orchestration service
• Remove duplicate input guardrail checks from individual workflows
• Verify all workflows now protected by early guardrail check
• Test input guardrail blocking at new location
• Update cost tracking (input guardrails now tracked before routing)
• Update specification document with new flow diagram
• Integration tests for input guardrail blocking
