Pre-processing Hook for Skills/Workflows Trigger Detection

This module implements the backend-side trigger detection that was previously described in the prompt. By moving this logic to code:

• Eliminates ambiguity in pattern matching
• Provides deterministic behavior
• Reduces prompt token cost (~100 lines removed from prompt)
• Enables easier testing and debugging

Dynamic Trigger Loading

Triggers are now loaded dynamically from skill files’ trigger field, instead of being hardcoded. This allows skills to define their own trigger patterns without modifying this code.

Auto-loading Skills

When a skill is triggered, the system can optionally auto-load the skill content, saving an extra round-trip.

Structs

PreProcessHook

Pre-processing hook for trigger detection

SkillPattern

Skill trigger pattern

WorkflowTrigger

Workflow trigger configuration

Enums

ProcessResult

Trigger type detection result

TriggerType

Type of trigger detected

Functions

global_preprocessor

Get the global preprocessor

preprocess

Process message with global preprocessor (without skills) Use preprocess_with_skills for dynamic trigger loading.

preprocess_with_skills

Process message with skills for dynamic trigger loading. This is the preferred function when skills are available.
