Theater Code Detection

When to Use This Skill

Trigger Conditions:

Before merging AI-generated code into main branch
When code review reveals suspiciously complete implementations
After detecting inconsistencies between documentation and behavior
As pre-deployment quality gate for critical systems
When integrating third-party or unfamiliar code
During security audits to identify fake security measures

Situations Requiring Theater Detection:

Code that compiles but doesn't execute meaningful logic
Functions with proper signatures but no-op implementations
Tests that always pass regardless of code changes
Security checks that can be bypassed trivially
Error handling that catches but doesn't handle errors
Mock implementations accidentally left in production code

Overview

Theater code is code that "performs" correctness without delivering actual functionality. It passes static analysis, looks structurally sound, and may even have tests—but fails to implement the intended behavior. This skill systematically identifies theater code through pattern recognition, execution analysis, and behavioral validation.

The detection process scans codebases for suspicious patterns (empty catch blocks, no-op functions, always-passing tests), analyzes implementations for meaningful logic, executes code to validate actual behavior, and reports findings with actionable recommendations for remediation.

   - Review all files in Critical category
   - Implement actual business logic
   - Add meaningful error handling

2. **Fix Empty Error Handlers**
   - Add proper error logging and recovery
   - Ensure errors propagate appropriately
   - Document error handling strategy

3. **Remove Always-Pass Tests**
   - Replace with meaningful assertions
   - Test actual behavior, not constants
   - Increase test coverage for critical paths

### Short-Term Actions (High Priority)
1. **Implement No-Op Functions**
   - Replace stub functions with real logic
   - Add comprehensive documentation
   - Update tests to cover new implementations

2. **Clean Up Incomplete Code**
   - Address all TODO/FIXME markers
   - Complete partial implementations
   - Remove dead code

### Long-Term Actions (Prevention)
1. **Establish Code Review Process**
   - Manual review for AI-generated code
   - Automated theater detection in CI/CD
   - Pair programming for critical components

2. **Improve Testing Standards**
   - Require meaningful test assertions
   - Enforce coverage thresholds
   - Validate behavior, not just structure

3. **Training and Documentation**

Phase 5: Fix Issues (Sequential)

Agents: coder (lead), reviewer (validation) Duration: 30-60 minutes (varies by issue count)

Scripts:

# Initialize phase
npx claude-flow hooks pre-task --description "Phase 5: Fix Theater Code Issues"
npx claude-flow swarm scale --target-agents 2

# Retrieve confirmed theater code
EXECUTION=$(npx claude-flow memory retrieve --key "testing/theater-detection/phase-3/tester/execution-results")

# Execute phase work
# 1. Create backup of original files
echo "Creating backups before fixes..."
mkdir -p .theater-detection-backups
echo $EXECUTION | jq -r '.confirmed_theater[].file' | while read file; do
  [ -f "$file" ] && cp "$file" ".theater-detection-backups/$(basename $file).backup"
done

# 2. Fix critical issues first (empty catches, no-ops)
echo "Fixing critical theater code..."

# Example: Fix empty catch blocks
find . -name "*.js" -type f ! -path "./node_modules/*" -exec sed -i.bak \
  's/catch\s*(\s*\(\w\+\)\s*)\s*{\s*}/catch (\1) {\n    console.error("Error caught:", \1);\n    throw \1;\n  }/g' {} \;

# Example: Fix no-op functions (requires manual review)
cat > fix-guide.md << 'EOF'
# Theater Code Fix Guide

## Files Requiring Manual Fixes

The following files contain theater code that requires manual implementation:

EOF

echo $CATEGORIES | jq -r '.critical[] | .file' | while read file; do
  echo "### $file" >> fix-guide.md
  echo "Indicators:" >> fix-guide.md
  echo $CATEGORIES | jq -r --arg f "$file" '.critical[] | select(.file == $f) | .theater_indicators[]' | \
    sed 's/^/- /' >> fix-guide.md
  echo "" >> fix-guide.md
done

# 3. Validate fixes don't break existing functionality
npm test > fix-validation.log 2>&1
FIX_EXIT_CODE=$?

if [ $FIX_EXIT_CODE -ne 0 ]; then
  echo "⚠️  Fixes introduced test failures. Review fix-validation.log"
fi

# 4. Track fixes applied
cat > fixes-applied.json << EOF

Evidence-Based Validation

Self-Consistency Checking

Before finalizing each phase:

Does this approach align with successful past work?
- Compare detection patterns with known theater code examples
- Validate analysis methods against proven techniques
- Ensure fix strategies follow established best practices
Do the outputs support the stated objectives?
- Verify detected issues are actually theater code, not false positives
- Confirm analysis identifies root causes accurately
- Ensure fixes resolve issues without introducing new problems
Is the chosen method appropriate for the context?
- Match detection depth to codebase size and criticality
- Scale analysis effort based on project risk profile
- Apply fix complexity proportional to issue severity
Are there any internal contradictions?
- Check that execution validation aligns with static analysis
- Verify severity categorization matches actual impact
- Confirm fixed code passes tests and meets requirements

Program-of-Thought Decomposition

Define objective precisely
- Objective: Identify non-functional code masquerading as complete
- Success metric: 100% of theater code detected and reported
- Constraint: Minimize false positives (< 10%)
Decompose into sub-goals
- Sub-goal 1: Scan codebase for suspicious patterns
- Sub-goal 2: Analyze implementations for meaningful logic
- Sub-goal 3: Validate actual execution behavior
- Sub-goal 4: Report findings with actionable recommendations
- Sub-goal 5: Apply fixes and validate no regressions
Identify dependencies
- Scanning must complete before analysis
- Analysis must complete before execution validation
- Validation must complete before reporting
- Reporting must complete before fixes
Evaluate options
- Detection approaches: Pattern matching vs. AST analysis vs. execution testing
- Analysis depth: Surface-level vs. deep semantic analysis
- Fix strategies: Automated vs. manual vs. hybrid
Synthesize solution
- Combine pattern matching for initial detection
- Use semantic analysis to reduce false positives
- Validate with execution tests for definitive confirmation
- Provide both automated fixes and manual guidance

Plan-and-Solve Framework

Planning Phase:

Define theater code patterns to detect
Establish confidence thresholds for categorization
Determine execution validation strategy
Create fix prioritization framework

Validation Gate 1: Review strategy

Does pattern list cover known theater types?
Are confidence thresholds appropriate?
Is execution validation comprehensive?
Are fix strategies sound?

Implementation Phase:

Execute Phases 1-5 with continuous monitoring
Track detection accuracy and false positive rate
Validate fixes don't break existing tests
Document findings and recommendations

Validation Gate 2: Verify outputs

All theater code detected (no false negatives)
False positive rate < 10%
Fixes applied successfully without regressions
Report comprehensive and actionable

Optimization Phase:

Refine detection patterns based on findings
Improve analysis heuristics
Enhance automated fix capabilities
Update prevention recommendations

Validation Gate 3: Confirm targets met

Theater code eliminated or documented
Quality gates updated to prevent recurrence
Team educated on patterns
Monitoring established for future detection

Common Issues and Solutions

Issue 1: High False Positive Rate

Symptoms: Many flagged files are actually functional Root Cause: Detection patterns too broad or strict Solution:

Refine detection heuristics with more context
Add AST-based semantic analysis
Increase confidence threshold for categorization
Manual review of borderline cases

Issue 2: Theater Code Not Detected

Symptoms: Known theater code passes detection Root Cause: Patterns don't match specific theater style Solution:

Expand pattern library with new examples
Add execution validation for all suspicious files
Lower confidence threshold temporarily
Perform manual audit of high-risk areas

Issue 3: Execution Validation Crashes

Symptoms: Test runner fails during validation Root Cause: Code has runtime dependencies or side effects Solution:

# Isolate execution in sandbox
docker run -it --rm -v $(pwd):/workspace node:18 bash -c "cd /workspace && npm test"

# Mock external dependencies
cat > test-setup.js << 'EOF'
global.fetch = jest.fn();
global.console = { log: jest.fn(), error: jest.fn() };
EOF

Issue 4: Automated Fixes Break Tests

Symptoms: Test suite fails after applying fixes Root Cause: Fixes too aggressive or context-unaware Solution:

Create backups before any fixes
Apply fixes incrementally and validate each
Prefer manual review for complex cases
Revert problematic fixes and document

Issue 5: Unable to Fix Complex Theater Code

Symptoms: Clear theater detected but fix is non-trivial Root Cause: Missing requirements or business logic knowledge Solution:

Generate detailed fix guide with context
Flag for manual developer review
Document expected behavior from tests/docs
Create stub implementations with TODOs

Examples

Example 1: Detecting Empty Error Handlers

# Scan for empty catches
grep -rn "catch.*{}" src/

# Output:
# src/auth/login.js:45: } catch (error) {}
# src/api/client.js:102: } catch (e) {}

# Analyze implementation
cat src/auth/login.js | sed -n '40,50p'
# Shows: try { await authenticate() } catch (error) {}
# Theater indicator: Errors silently swallowed

# Fix: Add proper error handling
sed -i 's/catch (error) {}/catch (error) { console.error("Authentication failed:", error); throw error; }/' src/auth/login.js

Example 2: Detecting No-Op Function

// Detected theater code
function validatePayment(transaction) {
  // TODO: Implement payment validation
  return true; // Always returns true!
}

// Analysis indicators:
// - Function always returns true
// - No computation or validation logic
// - TODO comment indicates incomplete work

// Fix: Implement actual validation
function validatePayment(transaction) {
  if (!transaction || typeof transaction !== 'object') {
    throw new Error('Invalid transaction object');
  }

  if (!transaction.amount || transaction.amount <= 0) {
    throw new Error('Invalid transaction amount');
  }

  if (!transaction.currency || !['USD', 'EUR', 'GBP'].includes(transaction.currency)) {
    throw new Error('Unsupported currency');
  }

  return true;
}

Example 3: Detecting Always-Pass Test

// Detected theater test
describe('Payment Processing', () => {
  test('processes payment correctly', () => {
    expect(true).toBe(true); // Always passes!
  });
});

// Analysis indicators:
// - Test assertion is tautology (true === true)
// - No actual code execution or validation
// - Provides false confidence in functionality

// Fix: Test actual behavior
describe('Payment Processing', () => {
  test('processes payment correctly', async () => {
    const transaction = {
      amount: 100,
      currency: 'USD',
      method: 'credit_card'
    };

    const result = await processPayment(transaction);

    expect(result).toHaveProperty('status');
    expect(result.status).toBe('success');
    expect(result).toHaveProperty('transactionId');
    expect(typeof result.transactionId).toBe('string');
  });

  test('rejects invalid payment', async () => {
    const transaction = { amount: -50 };

    await expect(processPayment(transaction))
      .rejects
      .toThrow('Invalid transaction amount');
  });
});
