Implementation Guide
1. TRUST 5 Framework - Quality Assurance System
Purpose: Automated quality gates ensuring code quality, security, and maintainability.
Five Pillars:
Tested Pillar: Maintain comprehensive test coverage with characterization tests ensuring behavior preservation. Execute pytest with coverage reporting. Block merge and generate missing tests on failure. Characterization tests capture current behavior for legacy code, while specification tests validate domain requirements for new code. High coverage ensures code reliability and reduces production defects. Preserves behavior during refactoring and reduces debugging time by 60-70 percent.
Readable Pillar: Use clear and descriptive naming conventions. Execute ruff linter checks. Issue warning and suggest refactoring improvements on failure. Clear naming improves code comprehension and team collaboration. Reduces onboarding time by 40 percent and improves maintenance velocity.
Unified Pillar: Apply consistent formatting and import patterns. Execute black formatter and isort checks. Auto-format code or issue warning on failure. Consistency eliminates style debates and merge conflicts. Reduces code review time by 30 percent and improves readability.
Secured Pillar: Comply with OWASP security standards. Execute security-expert agent analysis. Block merge and require security review on failure. Security vulnerabilities create critical business and legal risks. Prevents 95+ percent of common security vulnerabilities.
Trackable Pillar: Write clear and structured commit messages. Match Git commit message regex patterns. Suggest proper commit message format on failure. Clear history enables debugging, auditing, and collaboration. Reduces issue investigation time by 50 percent.
Integration Points: Pre-commit hooks for automated validation, CI/CD pipelines for quality gate enforcement, Agent workflows for core-quality validation, Documentation for quality metrics.
Detailed Reference: modules/trust-5-framework.md
2. SPEC-First DDD - Development Workflow
Purpose: Specification-driven development ensuring clear requirements before implementation.
Three-Phase Workflow:
Phase 1 SPEC (/moai:1-plan): workflow-spec generates EARS format. Output is .moai/specs/SPEC-XXX/spec.md. Execute /clear to save 45-50K tokens.
Phase 2 DDD (/moai:2-run): ANALYZE for requirements, PRESERVE for existing behavior, IMPROVE for enhancement. Validate with at least 85% coverage.
Phase 3 Docs (/moai:3-sync): API documentation, architecture diagrams, project reports.
EARS Format: Ubiquitous for system-wide always active requirements. Event-driven for trigger-based when X do Y requirements. State-driven for conditional while X do Y requirements. Unwanted for prohibited shall not do X requirements. Optional for nice-to-have where possible do X requirements.
Token Budget: SPEC takes 30K, DDD takes 180K, Docs takes 40K, Total is 250K.
Key Practice: Execute /clear after Phase 1 to initialize context.
Detailed Reference: modules/spec-first-ddd.md
3. Delegation Patterns - Agent Orchestration
Purpose: Task delegation to specialized agents, avoiding direct execution.
Core Principle: MoAI must delegate all work through Task() to specialized agents. Direct execution bypasses specialization, quality gates, and token optimization. Proper delegation improves task success rate by 40 percent and enables parallel execution.
Delegation Syntax: Call Task with subagent_type parameter for specialized agent, prompt parameter for clear specific task, and context parameter with relevant data dictionary.
Three Patterns:
Sequential for dependencies: Call Task to api-designer for design, then Task to backend-expert for implementation with design context.
Parallel for independent work: Call Promise.all with Task to backend-expert and Task to frontend-expert simultaneously.
Conditional for analysis-based: Call Task to debug-helper for analysis, then based on analysis.type, call Task to security-expert or other appropriate agent.
Agent Selection: Simple tasks with 1 file use 1-2 agents sequential. Medium tasks with 3-5 files use 2-3 agents sequential. Complex tasks with 10+ files use 5+ agents mixed.
Purpose: Efficient 200K token budget through strategic context management.
Budget Allocation:
SPEC Phase takes 30K tokens. Strategy is to load requirements only and execute /clear after completion. Specification phase requires minimal context for requirement analysis. Saves 45-50K tokens for implementation phase.
DDD Phase takes 180K tokens. Strategy is selective file loading, load only implementation-relevant files. Implementation requires deep context but not full codebase. Enables 70 percent larger implementations within budget.
Docs Phase takes 40K tokens. Strategy is result caching and template reuse. Documentation builds on completed work artifacts. Reduces redundant file reads by 60 percent.
Total Budget is 250K tokens across all phases. Phase separation with context reset between phases provides clean context boundaries and prevents token bloat. Enables 2-3x larger projects within same budget.
Token Saving Strategies:
Phase Separation: Execute /clear between phases, after /moai:1-plan to save 45-50K, when context exceeds 150K, after 50+ messages.
Selective Loading: Load only necessary files.
Context Optimization: Target 20-30K tokens.
Model Selection: Sonnet for quality, Haiku for speed and cost with 70% cheaper rates for 60-70% total savings.

5. Progressive Disclosure - Content Architecture
Purpose: Three-tier knowledge delivery balancing value with depth.
Three Levels:
Quick Reference Level: 30 seconds time investment, core principles and essential concepts, approximately 1,000 tokens. Rapid value delivery for time-constrained users. Users gain 80 percent understanding in 5 percent of time.
Implementation Level: 5 minutes time investment, workflows, practical examples, integration patterns, approximately 3,000 tokens. Bridges concept to execution with actionable guidance. Enables immediate productive work without deep expertise.
Advanced Level: 10+ minutes time investment, deep technical dives, edge cases, optimization techniques, approximately 5,000 tokens. Provides mastery-level knowledge for complex scenarios. Reduces escalations by 70 percent through comprehensive coverage.
