Decision Logic Framework

Quick Reference (30 seconds)

Core Principle: Clear separation between Agents (orchestrators) and Skills (capabilities).

Decision Tree:

Need external Python packages? → UV Script (.py)
Need system commands?          → UV Script (.py)
Reference/documentation?       → Single-File MD (.md)
Simple data/rules?             → Single-File MD (.md)

Naming (Mandatory Prefixes):

• Scripts: {skill}_{action}.py (underscore)
• Modules: {category}-{topic}.md (hyphen)

Architecture Overview

Agents = Orchestrators with Workflows

.claude/agents/{category}/{agent-name}/
├── {agent-name}.md              # Agent definition
└── workflows/                    # Agent-owned workflows
    └── {workflow-name}/
        ├── WORKFLOW.toon        # Structure (TOON tabular)
        ├── instructions.md      # Overall guidance
        ├── checklist.md         # Validation (tier-2+)
        └── steps/
            └── step-NN-{action}.md

Skills = Capabilities with Scripts OR Modules

.claude/skills/{skill-name}/
├── SKILL.md                     # Main entry (REQUIRED)
├── scripts/                     # For complex automation (OPTIONAL)
│   └── {skill}_{action}.py      # UV scripts with prefix
└── modules/                     # For simple reference MDs (OPTIONAL)
    └── {category}-{topic}.md    # Single-file MDs with prefix

When to Use This Skill

Use this skill when:

• Creating a new skill and deciding between scripts vs modules
• Choosing workflow complexity tier (0-3)
• Naming new files (scripts or modules)
• Understanding the architecture separation
• Reverse-engineering third-party apps

Load Order: This skill should be loaded FIRST when creating any new skill, agent, or workflow.

Prefix Naming Quick Reference

Scripts (UV Python)

Pattern: {skill-name}_{action}.py
Separator: underscore (_)

Examples:
  kalshi_get-market.py
  kalshi_search-events.py
  system_analyze-cpu.py
  builder_generate-skill.py

Modules (Single-File MDs)

Pattern: {category}-{topic}.md
Separator: hyphen (-)

Categories: api, pattern, rule, guide, schema, example

Examples:
  api-endpoints.md
  pattern-authentication.md
  rule-naming-convention.md
  guide-quick-start.md

Works Well With

Agents:

• builder-skill - Skill creation with tier system
• builder-workflow - TOON + MD workflow generation
• builder-agent - Agent with workflows/ generation

Skills:

• moai-library-toon - TOON format reference
• moai-foundation-core - Core execution rules
• builder-skill-uvscript - UV script examples

Commands:

• /moai:1-plan - SPEC generation with decision framework
• /builder:generate-skill - Skill creation workflow
