Subject: [PATCH 1/7] feat: Add LLM analysis infrastructure for intelligent PR
 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.

Subject: [PATCH 2/7] feat: Enhance git_analyzer with optional LLM intelligence
 levels

- 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.

Subject: [PATCH 4/7] feat: Register new PR analysis tools with permission
 system

- 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.

+# PR Analysis and Cross-Branch Impact Assessment
+
+This document describes the new PR-level analysis features added to clippy, designed specifically for multi-branch development workflows and preventing cross-branch conflicts.
+
+## 🎯 Problem Statement
+
+Your friend described a common and critical challenge in modern software development:
+
+```
+main M (monolith)
+ -> primary feature F
+   -> subfeatureA
+   -> subfeatureB
+
+mobile (react native)
+  -> primary feature F'1
+```
+
+The core question: **How do we analyze commits in B as they might affect:**
+- F (parent feature)
+- A (sibling subfeature)  
+- M (main monolith)
+- F'1 (mobile feature)
+
+## 📎 Solution: Two New Tools
+
+### 1. `git_analyzer` - Advanced Git Analysis
+
+Deep analysis of git changes across multiple branches with semantic understanding.
+
+#### Key Features:
+- **Cross-branch impact analysis**: See how changes in one branch affect others
+- **Collision detection**: Identify files that conflict between branches  
+- **Semantic analysis**: Understand API changes, data model changes, dependency updates
+- **Risk assessment**: Automatic risk scoring (low/medium/high)
+- **Smart recommendations**: Context-aware safety recommendations
+
+#### Usage Example:
+```python
+git_analyzer(
+    base_branch="main",           # M - base monolith
+    feature_branch="feature/subfeatureB",  # B - source of changes
+    compare_branches=[            # Context branches
+        "feature/subfeatureA",    # A - sibling
+        "feature/primaryFeatureF", # F - parent
+        "mobile/primaryFeatureF1"  # F'1 - mobile
+    ],
+    analysis_depth="files",        # or "commits", "functions", "full"
+    include_semantic_analysis=True
+)
+```
+
+#### Result Structure:
+```json
+{
+  "impacts": {
+    "main": {
+      "risk_level": "medium",
+      "file_count": 12,
+      "line_count": 234,
+      "affected_areas": ["Core code", "Configuration"]
+    },
+    "feature/subfeatureA": {
+      "risk_level": "low",
+      "collision_risk": "medium"
+    }
+  },
+  "collisions": [
+    {
+      "branch": "feature/subfeatureA",
+      "analysis": {
+        "collision_risk": "medium",
+        "conflicting_files": ["src/utils/helpers.py"]
+      }
+    }
+  ],
+  "semantic_analysis": {
+    "api_changes": ["Potential API change in src/api/controllers.py"],
+    "semantic_impact_score": 0.7
+  },
+  "recommendations": [
+    "🔄 Collision risk with branch 'feature/subfeatureA'. Coordinate with that team before merging.",

+
+## 🔧 Integration with Existing Workflow
+
+### In Interactive Mode:
+Use the `/analyze` command to trigger PR analysis:
+```
+You: /analyze pr --source feature/subfeatureB --target main --context feature/subfeatureA,mobile/F1
+
+Clippy: 📎 I'll analyze the PR impact for you! Let me check how subfeatureB changes affect main and the context branches...
+
+[Analysis results displayed]
+```
+
+### In Document Mode:
+Use the PR Analysis panel to visualize cross-branch impacts and collision risks.
+
+### In Automated CI/CD:
+```bash
+# Pre-merge hook analysis
+python -m clippy --oneshot "Use git_analyzer to analyze changes in $SOURCE_BRANCH against $TARGET_BRANCH with context branches $CONTEXT_BRANCHES"
+```
+
+## 🎯 Advanced Use Cases
+
+### 1. Multi-Team Coordination
+```python
+# Analyze impact across multiple team branches
+git_analyzer(
+    base_branch="main",
+    feature_branch="team-backend/new-api",
+    compare_branches=[
+        "team-frontend/api-consumers", 
+        "team-mobile/native-app",
+        "team-qa/test-suite"
+    ]
+)
+```
+
+### 2. Release Safety Validation
+```python
+# Strict validation before release
+pr_manager(
+    action="validate",
+    source_branch="release/v2.1.0",
+    target_branch="main",
+    context_branches=["production/hotfixes"],
+    safety_level="strict"
+)
+```
+
+### 3. Feature Branch Dependencies
+```python
+# Check dependent feature branches
+git_analyzer(
+    base_branch="feature/auth-system",
+    feature_branch="feature/user-profiles",
+    compare_branches=["feature/social-integration"]
+)
+```
+
+## 🧠 Semantic Analysis Features
+
+The semantic analysis goes beyond line-by-line diffs:
+
+### API Change Detection
+- Identifies function/method signature changes
+- Detects new endpoints or removed APIs
+- Flags breaking changes
+
+### Data Model Impact
+- Recognizes database schema changes
+- Identifies configuration file modifications
+- Detects dependency version changes
+
+### Cross-Language Understanding
+- Works with Python, JavaScript, TypeScript, Java, C++, Go
+- Language-agnostic pattern matching
+- Framework-agnostic change analysis
+
+## 📋 Best Practices
+
+### 1. Set Safety Levels Appropriately
+- **Production releases**: Use `strict` mode
+- **Feature development**: Use `moderate` mode  
+- **Experimental features**: Use `permissive` mode
+
+### 2. Include All Context Branches
+- Always include sibling feature branches
+- Include platform-specific branches (mobile, web)
+- Include integration/testing branches
+
+### 3. Review Semantic Analysis
+- Pay attention to API change warnings
+- Check dependency impact scores
+- Review semantic impact scoring
+
+### 4. Use Staging for Critical Changes
+- Always stage changes that affect multiple contexts
+- Generate patches for backup and review
+- Create backup branches before risky operations
+
+## 🔍 Troubleshooting
+
+### Common Issues:
+1. **Branch not found**: Ensure all branches exist locally or track remote branches
+2. **No git repository**: Run from within a git repository
+3. **Timeout**: Large repositories may need longer analysis time
+4. **Merge conflicts**: Address conflicts before analysis for best results
+
+### Performance Tips:
+- Use `analysis_depth="commits"` for quick checks
+- Use `analysis_depth="full"` only when needed
+- Limit `compare_branches` to essential branches
+- Consider repository size when planning analysis
+
+## 📎 Happy Analyzing!
+
+These tools give your friend exactly what they need - comprehensive PR-level analysis that prevents breaking other contexts when making commits. The system analyzes not just the immediate changes, but their broader impact across the entire development ecosystem.
+
+Remember: In complex multi-branch development, it's not about preventing commits - it's about making *informed* commits! 📎✨

Subject: [PATCH 7/7] feat(llm): make LLM-enhanced analysis the default for all
 PR evaluations

- 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.
