Development Workflow: Real-World Examples

Practical demonstrations of Development Workflow methodology and Memory Bank principles in action

Introduction

This document provides concrete examples of how the Development Workflow methodology is applied in real AIRS ecosystem development. Each example demonstrates different aspects of the 6-phase development loop, confidence-driven strategy adaptation, and memory bank integration.

These examples are drawn from actual AIRS development tasks and show authentic implementations of the methodological frameworks documented in the main Development Workflow guide.

Example 1: Task-Driven Development with Memory Bank Integration

Scenario: Implementing file system navigation functionality for AIRS-MemSpec while maintaining complete context across AI collaboration sessions.

impl MemoryBankNavigator {
    /// Discover memory bank structure from any starting path
    pub fn discover_structure(start_path: &Path) -> FsResult<MemoryBankStructure> {
        // Memory Bank pattern: Always start with context understanding
        let memory_bank_root = Self::find_memory_bank_root(start_path)?;
        
        // Apply discovered pattern: Comprehensive discovery
        let workspace = Self::discover_workspace_files(&memory_bank_root)?;
        let current_context = Self::find_current_context(&memory_bank_root);
        let sub_projects = Self::discover_sub_projects(&memory_bank_root)?;
        
        // Validation integration (learned from previous memory bank projects)
        let structure = MemoryBankStructure {
            root_path: memory_bank_root,
            workspace,
