Skill Trigger Detector

Automatically detects when a user's message indicates they want to use a specific skill, then triggers that skill without requiring explicit menu navigation.

Purpose

Enable natural, conversational interaction with skills by detecting intent from user messages and automatically invoking the appropriate skill. Special handling for mother-brain with ASCII branding.

Operating Principles

  • •Intent detection: Analyze user messages for keywords and patterns that match skill capabilities
  • •Automatic invocation: Trigger skills seamlessly when intent is clear
  • •Skill metadata: Read trigger phrases from each skill's YAML frontmatter
  • •Mother-brain branding: Display ASCII alien brain art when mother-brain is triggered
  • •Fallback gracefully: If no clear intent, proceed with normal conversation
  • •No false positives: Only trigger when confidence is high

Steps

  1. •

    Gather Context via Wizard

    • •Use ask_user to understand what the user wants to configure
    • •Ask: "What would you like to set up?"
      • •Add trigger phrases to mother-brain skill
      • •View all skills and their current triggers
      • •Test trigger detection with sample messages
  2. •

    Execute Based on Choice

    If adding triggers to mother-brain:

    • •Display current mother-brain triggers (if any)
    • •Ask user: "What keywords or phrases should trigger mother-brain?"
    • •Update mother-brain SKILL.md metadata section with triggers
    • •Add ASCII alien brain art to mother-brain's branding

    If viewing skills:

    • •Scan all skills in .github/skills/
    • •Extract trigger phrases from metadata
    • •Display skill names with their triggers

    If testing triggers:

    • •Ask for sample user message
    • •Run detection logic
    • •Show which skill would be triggered (if any)
  3. •

    Update Mother-Brain Branding

    • •Add ASCII alien brain art at top of mother-brain SKILL.md
    • •Configure mother-brain to display branding on activation
    • •Ensure branding appears before wizard starts
  4. •

    Configure Trigger Detection Logic

    • •Create detection rules for mother-brain keywords:
      • •"create project", "start project", "build project"
      • •"new app", "make an app"
      • •"I want to create", "I want to build"
    • •Skills can define custom triggers in metadata:
      yaml
      metadata:
  triggers:
    - "format markdown"
    - "fix markdown"
    • •Detection priority: Exact match > Partial match > Semantic match
  5. •

    Validate

    • •Test trigger detection with various phrasings
    • •Ensure mother-brain ASCII art displays correctly
    • •Verify no false positives on unrelated messages
    • •Confirm skill invocation works seamlessly

Example Trigger Phrases

Mother-Brain:

  • •"I want to create a project"
  • •"Start a new project"
  • •"Build an application"
  • •"Make something new"

Other Skills (examples):

  • •"Format my markdown" → markdown-formatter
  • •"Create a skill" → skill-creator
  • •"Fix this bug" → debugger-helper

Notes

  • •Trigger detection runs BEFORE normal processing if user message starts with clear intent keyword
  • •Skills without defined triggers won't auto-activate
  • •User can always explicitly invoke skills with /skill-name or via menu
  • •Mother-brain is the primary beneficiary—other skills can opt-in via metadata
