Smart Build Context Analysis

Lightweight build error investigation with intelligent escalation to comprehensive analysis when complexity detected.

LLM: This smart analysis uses 200-500 tokens for simple issues vs 1500-2500+ tokens for full build context analysis

Smart Analysis Process

1. Quick Build Error Assessment (200-300 tokens)

# Rapid build error classification and complexity assessment
STORY_FILE="$1"
PROJECT_DIR="."

echo "🔍 Smart Build Context Analysis"

# Auto-initialize language environment if needed
if [ -z "$BMAD_PRIMARY_LANGUAGE" ]; then
  Read tool: bmad-core/tasks/auto-language-init.md
fi

echo "🔍 Smart Build Context Analysis ($BMAD_PRIMARY_LANGUAGE)"

# Language-adaptive build and error analysis
BUILD_OUTPUT=$($BMAD_BUILD_COMMAND 2>&1)
BUILD_EXIT_CODE=$?

if [ $BUILD_EXIT_CODE -eq 0 ]; then
  echo "✅ Build successful - no context analysis needed"
  exit 0
fi

# Language-specific error counting
TOTAL_ERRORS=$(echo "$BUILD_OUTPUT" | grep -c -E "$BMAD_ERROR_PATTERNS")
SYNTAX_ERRORS=$(echo "$BUILD_OUTPUT" | grep -c -i "syntax\|parse")
TYPE_ERRORS=$(echo "$BUILD_OUTPUT" | grep -c -i "undefined\|not found\|cannot find")
INTERFACE_ERRORS=$(echo "$BUILD_OUTPUT" | grep -c -i "interface\|implementation\|abstract")

echo "📊 Build Error Summary:"
echo "Total Errors: $TOTAL_ERRORS"
echo "Syntax Errors: $SYNTAX_ERRORS" 
echo "Type/Reference Errors: $TYPE_ERRORS"
echo "Interface/Implementation Errors: $INTERFACE_ERRORS"

# Calculate complexity score
COMPLEXITY_SCORE=0
if [ $TOTAL_ERRORS -gt 20 ]; then COMPLEXITY_SCORE=$((COMPLEXITY_SCORE + 30)); fi
if [ $INTERFACE_ERRORS -gt 5 ]; then COMPLEXITY_SCORE=$((COMPLEXITY_SCORE + 25)); fi  
if [ $TYPE_ERRORS -gt 10 ]; then COMPLEXITY_SCORE=$((COMPLEXITY_SCORE + 20)); fi
if [ $SYNTAX_ERRORS -gt 5 ]; then COMPLEXITY_SCORE=$((COMPLEXITY_SCORE + 15)); fi

echo "🎯 Complexity Score: $COMPLEXITY_SCORE/100"

2. Smart Decision Logic (50-100 tokens)

# Intelligent routing based on complexity
if [ $COMPLEXITY_SCORE -lt 30 ]; then
  echo "🚀 SIMPLE - Using lightweight fix suggestions"
  provide_quick_build_fixes
  echo "💡 Tokens saved: ~2000 (avoided comprehensive analysis)"
  exit 0
elif [ $COMPLEXITY_SCORE -lt 60 ]; then
  echo "⚖️ MODERATE - Using targeted analysis"
  provide_targeted_context_analysis
  echo "💡 Tokens used: ~800 (focused analysis)"
  exit 0
else
  echo "🔄 COMPLEX - Escalating to comprehensive build context analysis"
  Read tool: bmad-core/tasks/build-context-analysis.md
  exit $?
fi

3. Quick Build Fixes (200-300 tokens)

provide_quick_build_fixes() {
  echo "🔧 Quick Build Fix Suggestions:"
  
  # Common syntax fixes
  if [ $SYNTAX_ERRORS -gt 0 ]; then
    echo "📝 Syntax Issues Detected:"
    echo "• Check for missing semicolons, braces, or parentheses"
    echo "• Verify method/class declarations are properly closed"
    echo "• Look for unmatched brackets in recent changes"
  fi
  
  # Missing references
  if [ $TYPE_ERRORS -gt 0 ]; then
    echo "📦 Missing Reference Issues:"
    echo "• Add missing using statements"
    echo "• Verify NuGet packages are installed"
    echo "• Check if types were moved to different namespaces"
  fi
  
  # Simple interface mismatches
  if [ $INTERFACE_ERRORS -gt 0 ] && [ $INTERFACE_ERRORS -lt 5 ]; then
    echo "🔌 Interface Implementation Issues:"
    echo "• Implement missing interface members"
    echo "• Check method signatures match interface contracts"  
    echo "• Verify async/sync patterns are consistent"
  fi
  
  echo ""
  echo "⏱️ Estimated fix time: 10-20 minutes"
  echo "🎯 Focus on most recent file changes first"
}

4. Targeted Context Analysis (400-600 tokens)

provide_targeted_context_analysis() {
  echo "🎯 Targeted Build Context Analysis:"
  
  # Focus on most problematic files
  PROBLEM_FILES=$(echo "$BUILD_OUTPUT" | grep "error " | cut -d'(' -f1 | sort | uniq -c | sort -nr | head -5)
  
  echo "📁 Most Problematic Files:"
  echo "$PROBLEM_FILES"
  
  # Quick git history for problem files  
  echo "🕰️ Recent Changes to Problem Files:"
  echo "$PROBLEM_FILES" | while read count file; do
    if [ -f "$file" ]; then
      LAST_CHANGE=$(git log -1 --format="%h %s" -- "$file" 2>/dev/null || echo "No git history")
      echo "• $file: $LAST_CHANGE"
    fi
  done
  
  # Check for interface evolution patterns
  if [ $INTERFACE_ERRORS -gt 0 ]; then
    echo "🔍 Interface Evolution Check:"
    INTERFACE_CHANGES=$(git log --oneline -10 --grep="interface\|API\|contract" 2>/dev/null | head -3)
    if [ -n "$INTERFACE_CHANGES" ]; then
      echo "$INTERFACE_CHANGES"
      echo "💡 Recent interface changes detected - may need implementation updates"
    fi
  fi
  
  echo ""
  echo "🔧 Targeted Fix Strategy:"
  echo "1. Focus on files with highest error counts first"
  echo "2. Check recent git changes for context"
  echo "3. Update interface implementations before complex logic"
  echo "4. Test incrementally after each file fix"
}

Escalation Triggers

When to Use Comprehensive Analysis

Complexity score ≥ 60
Interface errors > 10
Total errors > 50
User explicitly requests via *build-context --full
Previous quick fixes failed

Escalation Logic (50 tokens)

# Smart escalation with context preservation
escalate_to_comprehensive() {
  echo "📋 Preserving quick analysis results for comprehensive audit..."
  echo "Complexity Score: $COMPLEXITY_SCORE" > tmp/build-context-quick.txt
  echo "Error Counts: Total=$TOTAL_ERRORS, Interface=$INTERFACE_ERRORS" >> tmp/build-context-quick.txt
  echo "Problem Files: $PROBLEM_FILES" >> tmp/build-context-quick.txt
  
  echo "🔄 Executing comprehensive build context analysis..."
  Read tool: bmad-core/tasks/build-context-analysis.md
}

Integration with Development Workflow

Dev Agent Integration

# Replace direct build-context-analysis.md calls with smart analysis
*build-context           # Smart analysis (200-800 tokens) 
*build-context --full    # Force comprehensive analysis (1500+ tokens)
*build-context --quick   # Force lightweight fixes only (300 tokens)

Auto-Trigger Conditions

Build failures during story development
Compilation errors > 5
Interface implementation errors detected

Token Usage Comparison

Smart Hybrid	300-2,500	Adaptive based on complexity	80%

Expected Token Savings

Scenario Analysis

Build errors per day: 8-12 incidents
Simple issues (60%):
- Old: 8 × 2,000 = 16,000 tokens
- New: 8 × 300 = 2,400 tokens
- Savings: 85%
Moderate issues (25%):
- Old: 3 × 2,000 = 6,000 tokens
- New: 3 × 600 = 1,800 tokens
- Savings: 70%
Complex issues (15%):
- Old: 2 × 2,000 = 4,000 tokens
- New: 2 × 2,000 = 4,000 tokens
- Savings: 0% (but gets full analysis when needed)

Overall Daily Savings: 76% (from 26,000 to 8,200 tokens)
