Commit Analysis & Regression Detection
Overview
Automated tools for detecting regressions and analyzing code changes:
| Tool | Purpose | Speed |
|---|---|---|
| scripts/smart_commit_analyzer.py | Auto-evolving regression detection | Fast |
| scripts/analyze_commits_ai.py | AI semantic analysis (DeepSeek) | Slow |
| scripts/analyze_git_changes.py | Git history statistics | Fast |
| scripts/validate_commit_fixes.py | Legacy manual rules (deprecated) | Fast |
Recommended Tool: smart_commit_analyzer.py
This is the primary regression detection tool. Rules are automatically generated from git history.
Commands
# Full analysis (update rules + validate)
python3 scripts/smart_commit_analyzer.py
# Update rules only (scan git for new fixes)
python3 scripts/smart_commit_analyzer.py --update
# Validate only (check existing rules)
python3 scripts/smart_commit_analyzer.py --validate
# Show all rules
python3 scripts/smart_commit_analyzer.py --show-rules
# JSON output (for CI/CD)
python3 scripts/smart_commit_analyzer.py --json
Expected Output

How It Works
┌─────────────────────────────────────────────────────────┐
│ Step 1: git log --grep="fix" │
│ → Auto-discover all fix commits │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ Step 2: git show <commit> -- <file> │
│ → Extract key code patterns from diffs │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ Step 3: Save to configs/auto_generated_rules.json │
│ → Rules auto-grow with new fix commits │
└─────────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────────┐
│ Step 4: Validate all rules │
│ → Detect regressions (missing patterns) │
└─────────────────────────────────────────────────────────┘
AI Deep Analysis (Optional)
Requires DEEPSEEK_API_KEY environment variable.
# Analyze last 10 commits with AI
python3 scripts/analyze_commits_ai.py --commits 10
# JSON output
python3 scripts/analyze_commits_ai.py --commits 10 --json
Git History Analysis
# Analyze last 50 commits
python3 scripts/analyze_git_changes.py
# Show only fix commits
python3 scripts/analyze_git_changes.py --fix-only
# Analyze more commits
python3 scripts/analyze_git_changes.py --commits 100
GitHub Actions Integration
These tools run automatically on every push/PR via .github/workflows/commit-analysis.yml:
| Job | Tool | Trigger |
|---|---|---|
| Smart Regression Detection | scripts/smart_commit_analyzer.py | Always |
| AI Deep Analysis | scripts/analyze_commits_ai.py | If DEEPSEEK_API_KEY set |
Key Files
| File | Purpose |
|---|---|
scripts/smart_commit_analyzer.py |
Main regression detection tool |
configs/auto_generated_rules.json |
Auto-generated validation rules |
scripts/analyze_commits_ai.py |
AI-powered analysis |
scripts/analyze_git_changes.py |
Git history parser |

GitHub Actions workflow |
When to Run
- Before committing:
python3 scripts/smart_commit_analyzer.py - Before merging PR: Automatic via GitHub Actions
- After pulling updates:
python3 scripts/smart_commit_analyzer.py --validate - Investigating regressions:
python3 scripts/smart_commit_analyzer.py --show-rules
Interpreting Results
| Status | Meaning | Action |
|---|---|---|
| ✅ Passed | Pattern found in code | None |
| ❌ Failed | Pattern missing (potential regression) | Investigate |
| ⚠️ Warning | Pattern may have been refactored | Review |
| ⏭️ Skipped | File not found (renamed/deleted) | Update rules |
