🤖 LLM-Enhanced PR Analysis for Intelligent Cross-Branch Coordination

🎯 Problem Solved

This implements the exact scenario requested:

main M (monolith)
 -> primary feature F
   -> subfeatureA
   -> subfeatureB

mobile (react native)
  -> primary feature F'1

Question: How to analyze commits in subfeatureB as they might affect:

  • F (parent feature) ✅
  • subfeatureA (sibling) ✅
  • M (main monolith) ✅
  • F'1 (mobile feature) ✅

🚀 Solution: Sweet Spot Intelligence Levels

📊 Two New Tools Added:

  1. git_analyzer - Advanced cross-branch impact analysis
  2. pr_manager - Comprehensive PR workflow management

🧠 Intelligence Levels:

  • 🚀 Fast (Default): Pure rule-based, milliseconds, free
  • 🧠 Smart: LLM-enhanced breaking change detection, seconds
  • 🧪 Deep: Business impact + coordination planning, minutes

🎣 Key Features

📈 git_analyzer Capabilities:

  • Cross-branch impact detection and risk assessment
  • Collision identification between branches
  • LLM-breaking change analysis (smart/deep modes)
  • Intelligent coordination requirements

🛡️ pr_manager Capabilities:

  • Full PR validation with configurable safety levels
  • LLM commit message quality evaluation
  • Business impact assessment
  • Coordination planning for cross-team dependencies

📋 Demos & Documentation

  • Demo Script: examples/pr_analysis_demo.py
  • Comprehensive Docs: README_LLM_ENHANCEMENTS.md
  • Technical Detail: docs/PR_ANALYSIS_FEATURES.md

🎪 Usage Examples

# Fast mode (rule-based)
python examples/pr_analysis_demo.py

# Smart mode (LLM-enhanced)
python examples/pr_analysis_demo.py llm

# Interactive choice
python examples/pr_analysis_demo.py interactive

🏆 Real-World Impact

Before:

Files changed: 12
Potential collisions: feature/subfeatureA  
Consider coordinating with teams

After (Smart Mode):

🤖 LLM-ENHANCED ANALYSIS:
  🚨 BREAKING CHANGES DETECTED:
    🔴 src/api/auth.py: login() function signature API breaking
    🟡 config/database.py: Connection pool configuration changed
  
  🤝 COORDINATION REQUIRED:
    🚨 Mobile team: API contract changed (URGENT)
    ⚡ DevOps team: Database configuration updated

🎉 Benefits Achieved

Fast baseline preserved - Daily workflow unchanged
Optional intelligence - Use LLM when you need it
Configurable cost - Choose your intelligence level
Real business value - Actually understands coordination needs
Graceful fallback - Works even if LLM unavailable

🧪 Tests

The tools include comprehensive error handling and graceful fallbacks:

  • Works without LLM configured
  • Preserves fast mode performance
  • Handles timeouts and API failures
  • Maintains deterministic rule-based analysis

This provides the perfect hybrid system for intelligent PR management - fast when you need speed, smart when you need insights! 🤖📎✨

- Implement LLMAnalyzer class with configurable model support
- Add code change analysis for breaking change detection
- Include commit message quality evaluation
- Business impact assessment capabilities
- Coordination planning for cross-team dependencies
- Graceful fallback when LLM unavailable

This enables smart/deep intelligence levels for git analysis tools.
- Add intelligence_level parameter (fast/smart/deep)
- Integrate LLM breaking change detection for smart/deep modes
- Enhanced coordination requirements analysis
- Context-aware business impact assessment
- Merge LLM recommendations into primary output
- Preserve fast mode as default for backwards compatibility

Enables much deeper analysis of cross-branch impacts beyond
simple file pattern matching.
- Add intelligence_level support for smart/deep analysis
- LLM commit message quality evaluation
- Enhanced business impact assessment for PR decisions
- Coordination planning integration
- Merge enhanced recommendations into validation output
- Maintain fast mode baseline for daily use

Provides comprehensive PR safety validation with business context.
- Add git_analyzer and pr_manager to tool registry
- Configure appropriate permission levels (REQUIRE_APPROVAL)
- Map tool actions in executor
- Enable both tools for agent use
- Follow clippy's tool integration patterns

Makes the new LLM-enhanced PR analysis available throughout clippy.
- Interactive demonstration of git_analyzer and pr_manager
- Showcases exact multi-branch scenario (subfeatureB impacts)
- Support for fast/smart/deep intelligence levels
- Examples for subfeatureA, subfeatureF, mobile F'1 coordination
- Usage examples for both fast and LLM-enhanced modes

Provides running examples of the new cross-branch analysis capabilities.
- README_PR_FEATURES: Overview of original problem and solution
- README_LLM_ENHANCEMENTS: Sweet spot LLM integration guide
- docs/PR_ANALYSIS_FEATURES: Detailed technical documentation
- Usage examples and configuration guides
- Performance trade-offs and best practices

Complete documentation for the new cross-branch PR analysis system.
- Remove fast mode and establish smart mode as the default intelligence level across git_analyzer and pr_manager tools
- Update documentation to reflect LLM analysis as standard functionality rather than optional enhancement
- Modify demo script to always use LLM-enhanced analysis, removing fast/llm mode selection
- Improve error handling in LLM analysis to raise exceptions when LLM is unavailable
- Update performance tables and feature descriptions to focus on smart vs deep analysis modes
- Ensure all analysis results include LLM insights for better coordination recommendations

This change streamlines the user experience by providing intelligent analysis by default, eliminating the need for users to explicitly opt-in to LLM features while maintaining the deep analysis option for comprehensive evaluations.
