v0.5.0: Prompt Chaining System

DocGenAI v0.5.0: Prompt Chaining System

This major release introduces a comprehensive prompt chaining framework that enables multi-step AI generation workflows while maintaining 100% backward compatibility.

🚀 Major Features

Prompt Chaining Framework

• Multi-step AI workflows: Break complex documentation tasks into focused steps
• Three pre-built strategies:
  • Simple: Single-step generation (default, backward compatible)
  • Enhanced: 3-step analyze → document → enhance workflow
  • Architecture: 4-step architecture analysis with diagram specifications
• Dependency resolution: Automatic step ordering and data flow management
• Error handling: Robust error handling with configurable fail-fast behavior

CLI Integration

• --chain/--no-chain flags for enabling/disabling chaining
• --chain-strategy option to select specific chain types
• Full backward compatibility - existing commands work unchanged
• Configuration override support

Index and Summary Separation

• index.md: Always generated navigational index of all documentation files
• summary.md: Generated only with chaining enabled for comprehensive architectural overview
• Fixed sequencing issue where index was generated before individual files

🔧 Technical Improvements

Architecture

• ChainContext: Manages state and results between steps
• PromptStep: Individual chain steps with dependencies and transformations
• PromptChain: Orchestrates execution with dependency resolution
• ChainBuilder: Pre-built chain configurations for common patterns

Testing

• 33 new tests for all chaining components
• 104 total tests with 100% pass rate
• Comprehensive coverage of chain execution, error handling, and integration

Bug Fixes

• Fixed cached result handling to properly regenerate files in target output directory
• Resolved index.md sequencing issue with cached results
• Enhanced error handling and logging throughout the system

📚 Documentation

Fresh Sample Output

• Complete regeneration using enhanced chaining strategy
• Showcases improved documentation quality with multi-step generation
• Demonstrates new index.md and summary.md functionality

Comprehensive Guides

• Updated README with detailed chaining strategy explanations
• Enhanced developer documentation with implementation examples
• Performance comparisons and usage recommendations

⚡ Performance

Strategy	Steps	Quality	Speed (macOS)	Use Case
Simple	1	Good	~17s	Quick docs, CI/CD
Enhanced	3	Better	~50s	Production docs
Architecture	4	Best	~70s	Complex systems

🔄 Backward Compatibility

• Chaining disabled by default - existing workflows unchanged
• All existing CLI commands work exactly as before
• Configuration remains optional and backward compatible
• No breaking changes to existing APIs

🛠️ Configuration

Enable chaining in config.yaml:

chaining:
  enabled: true
  default_strategy: "enhanced"
  max_steps: 10
  timeout_per_step: 300
  fail_fast: true

📈 What's Next

This release provides the foundation for future enhancements:

• Architecture diagram generation
• Multi-perspective documentation
• Quality enhancement workflows
• Parallel step execution
• Custom transformation functions

🔗 Differences from v0.4.0

• New: Complete prompt chaining system with 3 pre-built strategies
• New: Index/summary separation for better navigation
• New: 33 comprehensive tests for chaining functionality
• Enhanced: Fresh sample output showcasing improved quality
• Fixed: Cached result handling and index sequencing issues
• Improved: Documentation with comprehensive chaining guides
