## Key Features Implemented
### 1. Quality Trend Analysis
Tracks metrics over time with directional indicators:
- 📈 Improving (metric getting better)
- 📉 Declining (metric getting worse)
- ➡️ Stable (no significant change)
Strength indicators:
- ⚡ Strong (>5% change)
- 🔄 Moderate (1-5% change)
- 📍 Weak (<1% change)
**Example Output**:
```
### 📉 build_status ⚡
- **Current:** 0
- **Previous:** 88.65
- **Change:** -88.65 (+100.0%)
- **Direction:** declining
- **Strength:** strong
- **Data Points:** 189
```
### 2. Alert System
Automatic alerts for quality degradation:
| Severity | Threshold | Action Required |
|----------|-----------|-----------------|
| 🔴 Critical | >20% change | Immediate investigation |
| 🟡 Warning | 10-20% change | Investigate within 24h |
| 🟢 Info | 5-10% change | Monitor closely |
**Example Alert**:
```markdown
### 🔴 CRITICAL: build_status
- **Message:** build_status has declined by 100.0% (from 88.65 to 0)
- **Current Value:** 0
- **Previous Value:** 88.65
- **Change:** 100.0%
```
### 3. Command Statistics
Execution patterns analysis:
- Total executions and success rates
- Average execution time
- Failure counts
- Performance metrics
**Sample Output**:
```
| Command | Executions | Success Rate | Avg Time | Failures |
|---------|------------|--------------|----------|----------|
| test | 76 | 57.9% | 7.710s | 32 |
| lint | 75 | 65.3% | 0.132s | 26 |
| check | 30 | 60.0% | 20.380s | 12 |
```
### 4. Performance Metrics
Identifies optimization opportunities:
- Slowest/fastest commands
- Execution time distribution
- Performance trends
### 5. Project Insights
Per-project analysis:
- Execution count
- Success rate
- Average time
- Active days
### 6. Recommendations Engine
Actionable insights based on analysis:
- Critical alerts for immediate action
- Performance optimization suggestions
- Quality improvement recommendations
- Positive reinforcement for improvements
## Usage Examples
### Basic Report Generation
```bash
# 30-day comprehensive report
python scripts/monitor_crackerjack_metrics.py
# Last 7 days
python scripts/monitor_crackerjack_metrics.py --days 7
# Save to file
python scripts/monitor_crackerjack_metrics.py --output report.md
# JSON for automation
python scripts/monitor_crackerjack_metrics.py --format json
```
### Automation Examples
**Weekly Cron Job**:
```bash
0 9 * * 1 cd /Users/les/Projects/session-buddy && \
python scripts/monitor_crackerjack_metrics.py \
--days 7 \
--output ~/weekly_metrics.md
```
**CI/CD Integration**:
```bash
# Check for quality degradation
python scripts/monitor_crackerjack_metrics.py --days 1 --format json > metrics.json
# Fail build on critical alerts
if jq -e '.quality_alerts[] | select(.severity == "critical")' metrics.json; then
echo "Quality degradation detected!"
exit 1
fi
```
**Slack Notifications**:
```bash
# Alert on critical issues
ALERTS=$(python scripts/monitor_crackerjack_metrics.py --days 1 --format json | \
jq -r '.quality_alerts[] | select(.severity == "critical") | .message')
if [ -n "$ALERTS" ]; then
curl -X POST $SLACK_WEBHOOK -d "{\"text\": \"🚨 $ALERTS\"}"
fi
```
## Data Analysis Insights
### Current Data Snapshot
**Database**: `~/.claude/data/crackerjack_integration.db`
**Total Records**: 18,980+
- 6,690 command results
- 7,381 quality metrics
- 4,909 progress snapshots
**Key Findings from Analysis**:
1. **Build Status**: CRITICAL decline (100% drop from 88.65% to 0%)
- Immediate investigation needed
- Recent builds all failing
2. **Test Execution**: 57.9% success rate (32/76 failures)
- High failure rate indicates test instability
- Environment or dependency issues likely
3. **Lint & Security**: Both at 100% - excellent
- Code quality is high
- No security issues detected
4. **Performance**: `all` command averaging 117.3s
- Needs optimization
- Consider parallel execution
5. **Project Activity**: 219 executions in current directory
- Most active project
- 69% success rate needs improvement
## Dashboard Integration
### Recommended Tools
**1. Grafana** (already configured in MCP)
```sql
-- Time series query
SELECT
timestamp as time,
metric_value as value,
metric_type as metric
FROM quality_metrics_history
WHERE $__timeFilter(timestamp)
AND metric_type = 'build_status'
ORDER BY timestamp
```
**2. Streamlit** (Python dashboard)
```python
import streamlit as st
import pandas as pd
# Load data
df = pd.read_sql("SELECT * FROM quality_metrics_history", conn)
# Create dashboard
st.title("Crackerjack Metrics")
st.metric("Build Success Rate", "68.0%", "-5%")
```
**3. Power BI / Tableau**
- Use SQLite connector
- Custom SQL queries
- Calculated fields for trends
### Dashboard Layout Recommendations
**Top Row**: KPI Cards (executions, success rate, avg time)
**Middle**: Time series charts (quality trends)
**Bottom**: Command distribution, performance metrics
## Technical Implementation
### Database Schema Used
```sql
-- Primary tables analyzed
crackerjack_results -- Command execution history
quality_metrics_history -- Quality metric snapshots
test_results -- Individual test results
progress_snapshots -- Progress tracking data
```
### Key SQL Patterns
**Trend Analysis**:
```sql
SELECT
metric_type,
AVG(CASE WHEN timestamp >= mid_point THEN metric_value ELSE NULL END) as current_avg,
AVG(CASE WHEN timestamp < mid_point THEN metric_value ELSE NULL END) as previous_avg
FROM quality_metrics_history
WHERE timestamp >= ?
GROUP BY metric_type
```
**Performance Metrics**:
```sql
SELECT
command,
AVG(execution_time) as avg_time,
COUNT(*) as executions
FROM crackerjack_results
WHERE timestamp >= ?
GROUP BY command
HAVING executions >= 3
ORDER BY avg_time DESC
```
