## Overview

Workflow optimization in Crackerjack leverages git metrics to provide data-driven recommendations for improving your development efficiency. By analyzing your commit patterns, branch behavior, merge success rates, and compliance with best practices, Crackerjack generates actionable insights that help you deliver faster with fewer bottlenecks.

The system operates on a simple principle: **measure, analyze, improve**. During each session, Crackerjack collects comprehensive git metrics without impacting your workflow. These metrics feed into a workflow efficiency score (0-100) that reflects the overall health of your development process. Based on this score and specific metric patterns, Crackerjack generates prioritized recommendations tailored to your situation.

### Key Benefits

- **Faster Delivery**: Identify and eliminate bottlenecks in your workflow
- **Higher Quality**: Catch problematic patterns before they become habits
- **Data-Driven Decisions**: Base improvements on actual metrics, not assumptions
- **Continuous Improvement**: Track trends over time and measure the impact of changes
- **Agent Integration**: Git metrics boost relevant AI agents for more targeted assistance

______________________________________________________________________

## How It Works

The workflow optimization system operates through four interconnected stages: **collection**, **calculation**, **recommendation**, and **action**. Each stage builds on the previous one to transform raw git data into actionable guidance.

### Stage 1: Git Metrics Collection

During active development sessions, Crackerjack automatically collects git metrics by analyzing your repository state and history. This process is non-invasive and adds negligible overhead (~10-50ms per session). The metrics collected fall into four categories:

**Commit Velocity Metrics**: Track your commit frequency and timing patterns. High, steady velocity (2-4 commits per hour) correlates with productive sessions. Spikes or drops can indicate focus issues or context switching. The system measures commits per hour, time since last commit, and tracks velocity trends across sessions.

**Branch Pattern Metrics**: Analyze your branching and merging behavior. Short-lived branches with frequent merges indicate smooth workflow progression. Long-lived branches suggest integration debt or stalled work. Metrics include branch age, number of branches, merge frequency, and the ratio of merges to total commits.

**Merge Success Metrics**: Measure how often your changes integrate successfully. High merge success rates indicate clean, well-tested code. Low rates suggest conflicts, quality issues, or integration problems. The system tracks successful merges versus failed attempts, conflict frequency, and time to resolve merge issues.

**Compliance Metrics**: Evaluate adherence to development best practices, particularly conventional commit formatting. Well-formatted commits with clear intent improve project history readability and enable better automation. Compliance is measured as the percentage of commits following the `type(scope): description` format.

### Stage 2: Workflow Efficiency Score

All collected metrics feed into a single **Workflow Efficiency Score** (0-100) calculated using a weighted formula that prioritizes the most impactful metrics:

```
Efficiency Score = (commit_velocity_weight * normalized_velocity) +
                   (merge_success_weight * merge_success_rate) +
                   (compliance_weight * compliance_rate) +
                   (branch_health_weight * branch_efficiency)
```

The default weights emphasize merge success (40%) and commit velocity (30%) as the strongest indicators of workflow health, with compliance (20%) and branch patterns (10%) providing context. This score is computed at the end of each session and stored for trend analysis.

A score of **80+** indicates excellent workflow health, **60-79** suggests room for improvement, **40-59** signals significant issues, and **below 40** requires immediate attention. The absolute score matters less than the trend: rising scores show improvement, while declining scores indicate emerging problems.

### Stage 3: Recommendation Generation

Based on the workflow efficiency score and specific metric thresholds, Crackerjack generates prioritized recommendations using the same severity system as other quality checks:

- **CRITICAL**: Efficiency < 40% OR merge success rate < 50%. Immediate action required to prevent workflow collapse.
- **HIGH**: Efficiency < 60% OR merge success rate < 70%. Significant issues impacting productivity.
- **MEDIUM**: Efficiency < 80% OR compliance rate < 70%. Moderate issues causing friction.
- **LOW**: All metrics healthy. Optional optimizations for continued improvement.

Each recommendation includes a **problem statement** explaining what's wrong, **impact** describing how it affects your workflow, **actionable steps** for improvement, and **expected improvement** if the recommendation is followed. Recommendations are context-aware: a low commit velocity during debugging generates different advice than the same metric during feature development.

### Stage 4: Agent Integration

Workflow optimization seamlessly integrates with Crackerjack's AI agent system through **agent boosting**. When specific metrics fall outside healthy ranges, the corresponding specialized agents receive priority during agent selection:

- Low merge success rate → Boosts `refactoring-agent` and `test-specialist-agent` for code quality improvements
- Low compliance rate → Boosts `documentation-agent` for commit message formatting
- High branch count or stale branches → Boosts `architect-agent` for workflow design improvements
- Erratic commit velocity → Boosts `semantic-agent` for analyzing development patterns

This intelligent routing ensures you get the right assistance at the right time, turning raw metrics into targeted support from Crackerjack's AI ecosystem.

______________________________________________________________________

## Configuration

Workflow optimization consists of two subsystems that can be enabled independently: **git metrics collection** and **workflow optimization recommendations**. Both are disabled by default and must be explicitly enabled in your configuration.

### Enabling Workflow Optimization

Add the following to `settings/local.yaml` (for local development) or `settings/crackerjack.yaml` (for project-wide settings):

```yaml
# Git Metrics Collection
# Controls collection of git repository metrics during sessions
git_metrics:
  enabled: true  # Default: false

# Workflow Optimization
# Generates recommendations based on git metrics analysis
workflow_optimization:
  enabled: true  # Default: false
```

### Verification

After enabling, verify the configuration is loaded correctly:

```bash
# Run with verbose output to confirm metrics collection
CRACKERJACK_DEBUG=1 python -m crackerjack run

# Check session summary for workflow efficiency score
python -m crackerjack run --run-tests
```

You should see output indicating git metrics collection and workflow efficiency scoring:

```
[DEBUG] Collecting git metrics...
[INFO] Workflow Efficiency Score: 72.3%
[INFO] Generated 3 workflow recommendations (1 HIGH, 2 MEDIUM)
```

### Partial Configuration

You can enable git metrics collection without enabling recommendations, useful for gathering baseline data before acting on it:

```yaml
git_metrics:
  enabled: true   # Collect metrics
workflow_optimization:
  enabled: false  # Don't generate recommendations yet
```

This mode stores metrics for analysis and trend tracking without displaying recommendations, allowing you to establish a baseline before making changes.

______________________________________________________________________

## Understanding Recommendations

Workflow optimization recommendations follow the same severity system as Crackerjack's quality checks, with four priority levels that indicate urgency and potential impact. Each recommendation includes contextual information to help you understand the issue and take appropriate action.

### CRITICAL Recommendations

**Definition**: Workflow efficiency below 40% OR merge success rate below 50%

**What It Means**: Your development workflow is in serious trouble. You're experiencing frequent merge conflicts, failing integrations, or extremely low productivity. This is the "smoke alarm" level—immediate action is required to prevent further deterioration.

**Common Causes**:

- Merge conflicts on >50% of pull requests
- Branches living for days/weeks without integration
- Commit velocity \<1 per hour (stalled development)
- Systematic violations of commit formatting (near 0% compliance)

**Actions to Take**:

1. **Address Immediate Blockers** (within 24 hours)

   - Identify and resolve active merge conflicts
   - Integrate stale branches or archive abandoned work
   - Establish a "merge daily" rule for active branches

1. **Root Cause Analysis**

   - Review recent commit history for patterns: `git log --oneline --since="2 weeks ago"`
   - Check branch ages: `git for-each-ref --sort=-committerdate refs/heads/ --format='%(refname:short) %(committerdate:relative)'`
   - Identify problematic workflows (e.g., large feature branches)

1. **Process Improvements**

   - Switch to trunk-based development or short-lived feature branches
   - Implement mandatory code review before merging
   - Add conventional commit enforcement via git hooks
   - Increase test coverage to catch integration issues earlier

**Expected Improvement**: Following CRITICAL recommendations typically increases workflow efficiency by 20-30 points within 1-2 weeks.

### HIGH Recommendations

**Definition**: Workflow efficiency below 60% OR merge success rate below 70%

**What It Means**: Your workflow has significant issues that impact productivity. You're likely experiencing frequent rework, delayed integrations, or inconsistent practices. This is the "check engine light" level—issues are causing real problems but aren't critical yet.

**Common Causes**:

- Merge conflicts on 30-50% of pull requests
- Inconsistent commit formatting (30-50% compliance)
- Erratic commit velocity (high variance between sessions)
- Branches living 2-5 days before integration

**Actions to Take**:

1. **Improve Merge Success** (within 1 week)

   - Implement pre-merge testing requirements
   - Use feature flags to integrate incomplete work safely
   - Establish "merge Friday" rituals to clear branch backlog
   - Add integration tests for common conflict areas

1. **Standardize Practices**

   - Adopt conventional commits: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`
   - Set up commit-msg hook: `echo "feat(scope): description" > .git/hooks/commit-msg.sample && chmod +x .git/hooks/commit-msg.sample`
   - Create team guidelines for branch naming and lifecycle

1. **Smoothen Commit Velocity**

   - Aim for 2-4 commits per hour during active development
   - Break large changes into smaller, logical commits
   - Use `git commit --amend` to consolidate related work
   - Set reminders for long gaps between commits

**Expected Improvement**: Following HIGH recommendations typically increases workflow efficiency by 10-20 points within 1-2 weeks.

### MEDIUM Recommendations

**Definition**: Workflow efficiency below 80% OR compliance rate below 70%

**What It Means**: Your workflow is functional but has room for improvement. You're doing well overall but have specific friction points that slow you down. This is the "maintenance required" level—issues are noticeable but not urgent.

**Common Causes**:

- Inconsistent commit formatting (50-70% compliance)
- Occasional long-running branches (5-7 days)
- Moderate commit velocity (1-2 commits per hour)
- Sporadic merge conflicts (10-20% of attempts)

**Actions to Take**:

1. **Refine Commit Hygiene** (within 2 weeks)

   - Audit recent commits for formatting: `git log --oneline -20 | grep -vE '^(feat|fix|docs|test|refactor|chore|perf|style)(\(.+\))?: '`
   - Add commitlint or similar tooling for enforcement
   - Document commit message standards for your team

1. **Optimize Branch Strategy**

   - Target maximum branch lifetime of 3-5 days
   - Use draft pull requests for early feedback
   - Implement branch-based code review policies
   - Consider trunk-based development for small teams

1. **Steady Your Pace**

   - Track commit velocity over time: `git log --since="1 month ago" --format="%ad" --date=format:"%Y-%m-%d %H" | uniq -c`
   - Identify and address causes of slow periods
   - Use time-blocking for focused development sessions

**Expected Improvement**: Following MEDIUM recommendations typically increases workflow efficiency by 5-10 points within 2-3 weeks.

### LOW Recommendations

**Definition**: All metrics in healthy ranges (efficiency ≥80%, compliance ≥70%, merge success ≥70%)

**What It Means**: Your workflow is in excellent shape! You're following best practices and maintaining high productivity. LOW recommendations are optional optimizations for teams seeking to squeeze out additional efficiency gains or prepare for scaling.

**Common Suggestions**:

- Fine-tune branch policies for larger teams
- Automate more of your workflow (CI/CD enhancements)
- Experiment with advanced development practices
- Share your successful patterns with other teams

**Actions to Take**:

1. **Optional Optimizations** (no deadline)

   - Experiment with pair programming or mob programming
   - Implement automated dependency updates
   - Add performance regression testing
   - Explore AI-assisted code review tools

1. **Knowledge Sharing**

   - Document your successful workflow patterns
   - Mentor other teams on best practices
   - Contribute back to Crackerjack with your insights
   - Present findings at team retrospectives

**Expected Improvement**: LOW recommendations provide marginal gains (2-5 points) but help build a culture of continuous improvement.

## Practical Examples

### Example 1: Interpreting Workflow Efficiency Score

After a development session, Crackerjack displays your workflow efficiency score:

```bash
$ python -m crackerjack run --run-tests

✅ Quality checks passed (2.3s)
✅ Tests passed (15.7s)

📊 Git Metrics Summary:
├─ Commit Velocity: 2.8 commits/hour (GOOD)
├─ Merge Success: 85% (GOOD)
├─ Branch Health: 3 active branches, 2.1 day avg lifetime (GOOD)
└─ Compliance: 45% (NEEDS IMPROVEMENT)

⚠️  Workflow Efficiency: 68.3/100 (MEDIUM)
   ↳ Most commits don't follow conventional format
   ↳ Recommendation: Adopt 'feat(scope): description' format
   ↳ Expected Improvement: +8-12 points

💡 Generated 2 recommendations
   ↳ [MEDIUM] Improve commit message formatting (45% → 70% target)
   ↳ [LOW] Reduce branch lifetime by 1 day (optional)
```

**Interpretation**:

- Overall workflow efficiency is **68.3/100**, putting you in the MEDIUM category
- Your **commit velocity** (2.8/hour) is healthy and consistent with focused development
- **Merge success** (85%) is excellent, indicating clean integrations
- **Branch health** is good, but there's room to reduce branch lifetime slightly
- **Compliance** (45%) is the main issue—most commits don't follow conventional format

**Action Plan**: Focus on commit message formatting first. Add a commit-msg hook, document the format for your team, and aim for 70% compliance over the next two weeks. This single change should boost your efficiency score into the HIGH range (75-80 points).

### Example 2: Acting on CRITICAL Recommendations

Your session reveals critical workflow issues:

```bash
$ python -m crackerjack run --run-tests

⚠️  Workflow Efficiency: 35.2/100 (CRITICAL)
   ↳ Multiple issues requiring immediate attention

🚨 Generated 3 CRITICAL recommendations:
   1. [CRITICAL] Merge success rate critically low (28%)
      ↳ Impact: 7 of last 10 merge attempts failed or had conflicts
      ↳ Action: Implement pre-merge testing and review all active branches
      ↳ Expected Improvement: +15-20 points

   2. [CRITICAL] Excessive branch count (12 active branches)
      ↳ Impact: Integration debt building, oldest branch is 23 days old
      ↳ Action: Archive abandoned branches, merge or close 8 branches this week
      ↳ Expected Improvement: +10-15 points

   3. [CRITICAL] Near-zero commit formatting compliance (5%)
      ↳ Impact: Unusable git history, unable to generate changelogs
      ↳ Action: Mandatory conventional commit training, add git hook enforcement
      ↳ Expected Improvement: +5-8 points

📋 Recovery Plan (estimated: +30-43 points)
   Week 1: Address merge issues, reduce branch count
   Week 2: Implement commit formatting standards
   Week 3: Monitor progress and adjust practices
```

**Immediate Actions**:

```bash
# Step 1: Assess branch situation
git for-each-ref --sort=-committerdate refs/heads/ \
  --format='%(refname:short) %(committerdate:relative) %(authorname)'

# Step 2: Identify stale/abandoned branches (>14 days old)
git for-each-ref --sort=-committerdate refs/heads/ \
  --format='%(refname:short) %(committerdate:relative)' \
  | awk '$2 ~ /[23][0-9] days|month/'

# Step 3: Review recent merge conflicts
git log --since="1 month ago" --merges --oneline | wc -l  # Total merges
git log --since="1 month ago" --oneline | grep "Merge conflict" | wc -l  # Conflicts

# Step 4: Set up conventional commit enforcement
cat > .git/hooks/commit-msg << 'EOF'
#!/bin/bash
commit_regex='^(feat|fix|docs|test|refactor|chore|perf|style)(\(.+\))?: .{1,72}$'
if ! grep -qE "$commit_regex" "$1"; then
  echo "❌ Invalid commit message format"
  echo "Expected: type(scope): description"
  echo "Example: feat(auth): add OAuth2 login support"
  exit 1
fi
EOF
chmod +x .git/hooks/commit-msg
```

### Example 3: Monitoring Trends Over Time

Track workflow efficiency trends by examining session history:

```bash
# View workflow efficiency history (last 30 days)
sqlite3 .session-buddy/session_metrics.db \
  "SELECT date(session_end), workflow_efficiency_score, commit_velocity,
          merge_success_rate, compliance_rate
   FROM session_metrics
   WHERE session_end >= date('now', '-30 days')
   ORDER BY session_end DESC;"

# Calculate weekly averages
sqlite3 .session-buddy/session_metrics.db \
  "SELECT
      strftime('%Y-W%W', session_end) as week,
      AVG(workflow_efficiency_score) as avg_efficiency,
      AVG(commit_velocity) as avg_velocity,
      AVG(merge_success_rate) as avg_merge_success
   FROM session_metrics
   WHERE session_end >= date('now', '-90 days')
   GROUP BY week
   ORDER BY week DESC;"
```

**Sample Output**:

```
Week        Avg Efficiency  Avg Velocity  Avg Merge Success
2025-W06    72.3            2.8           85%
2025-W05    68.1            2.5           82%
2025-W04    71.5            2.9           83%
2025-W03    65.2            2.1           78%
2025-W02    58.4            1.8           72%
2025-W01    55.7            1.6           70%
```

**Interpretation**: Steady improvement from 55.7 to 72.3 over six weeks (+16.6 points). The jump in Week 03 correlates with implementing conventional commits. Week 06 shows the benefit of consistent practices.

### Example 4: Integrating with Agent Selection

Workflow optimization boosts relevant agents based on git metrics:

```python
# Low merge success rate boosts refactoring and test specialists
if session_metrics.merge_success_rate < 0.7:
    boosted_agents = ["refactoring-agent", "test-specialist-agent"]
    # These agents get 1.5x priority during selection
    logger.info(f"Boosting {boosted_agents} due to low merge success")

# Low compliance boosts documentation agent
if session_metrics.compliance_rate < 0.7:
    boosted_agents.append("documentation-agent")
    logger.info("Boosting documentation-agent for commit hygiene")

# High branch count boosts architect agent
if session_metrics.active_branch_count > 8:
    boosted_agents.append("architect-agent")
    logger.info("Boosting architect-agent for workflow optimization")
```

**Practical Impact**: When you have merge issues, Crackerjack automatically prioritizes `refactoring-agent` and `test-specialist-agent` when analyzing your code, ensuring you get targeted help for your specific workflow problems.

## Troubleshooting

### Q: Git metrics are not being collected. How do I fix this?

**Symptoms**: No git metrics appear in session output, workflow efficiency score is not calculated.

**Diagnosis Steps**:

```bash
# 1. Verify git metrics are enabled in config
python -c "from crackerjack.config import settings; print(f'Git metrics enabled: {settings.git_metrics.enabled}')"

# 2. Check you're in a valid git repository
git status
# Should show: "On branch main" or similar

# 3. Verify git repository has commits
git log --oneline | head -5
# Should show commit history

# 4. Check file permissions
ls -la .git/
# Should show readable .git directory
```

**Common Solutions**:

1. **Not in a git repository**: Initialize git or navigate to the correct directory

   ```bash
   git init
   git add .
   git commit -m "feat: initial commit"
   ```

1. **Configuration not loaded**: Verify YAML syntax

   ```bash
   python -c "from crackerjack.config import CrackerjackSettings; s = CrackerjackSettings.load(); print(s.dict())"
   ```

1. **Insufficient git history**: Metrics need at least 5 commits for meaningful analysis

   ```bash
   # Create dummy commits for testing
   for i in {1..10}; do
     echo "test $i" > test.txt
     git add test.txt
     git commit -m "feat: test commit $i"
   done
   ```

### Q: No recommendations are being generated. Why?

**Symptoms**: Git metrics are collected, but no recommendations appear in session output.

**Diagnosis Steps**:

```bash
# 1. Verify workflow optimization is enabled
python -c "from crackerjack.config import settings; print(f'Workflow optimization enabled: {settings.workflow_optimization.enabled}')"

# 2. Check workflow efficiency score
sqlite3 .session-buddy/session_metrics.db \
  "SELECT workflow_efficiency_score FROM session_metrics ORDER BY session_end DESC LIMIT 1;"

# 3. Verify git metrics have sufficient data
sqlite3 .session-buddy/session_metrics.db \
  "SELECT commit_velocity, merge_success_rate, compliance_rate FROM session_metrics ORDER BY session_end DESC LIMIT 1;"
```

**Common Solutions**:

1. **All metrics healthy**: Efficiency score ≥80 generates no recommendations

   ```bash
   # Force a recommendation by temporarily lowering a metric
   # (This is for testing only)
   ```

1. **Insufficient data points**: Need at least 3 sessions with metrics

   ```bash
   # Run a few more sessions to build data
   python -m crackerjack run --run-tests
   python -m crackerjack run --run-tests
   python -m crackerjack run --run-tests
   ```

1. **Workflow optimization disabled**: Enable in config

   ```yaml
   # settings/local.yaml
   workflow_optimization:
     enabled: true
   ```

### Q: Recommendations seem wrong or don't match my situation. How do I debug this?

**Symptoms**: Recommendations don't align with observed behavior, efficiency score seems incorrect.

**Diagnosis Steps**:

```bash
# 1. Review raw git metrics for the session
sqlite3 .session-buddy/session_metrics.db \
  "SELECT * FROM session_metrics ORDER BY session_end DESC LIMIT 1;"

# 2. Manually calculate efficiency score
# From SessionMetrics.calculate_workflow_efficiency_score():
#   score = (velocity * 0.3) + (merge_success * 0.4) + (compliance * 0.2) + (branch_health * 0.1)
python -c "
velocity = 2.5      # commits/hour
merge_success = 0.85  # 85%
compliance = 0.45   # 45%
branch_health = 0.7  # 70%
score = (velocity/3 * 0.3) + (merge_success * 0.4) + (compliance * 0.2) + (branch_health * 0.1)
print(f'Efficiency Score: {score*100:.1f}')
"

# 3. Check recommendation generation logic
# In crackerjack/intelligence/session_metrics.py, line ~500
# Review _generate_workflow_recommendations() method
```

**Common Solutions**:

1. **Weights need adjustment**: Customize weights in your configuration

   ```python
   # Override default weights in settings/local.yaml
   workflow_optimization:
     weights:
       commit_velocity: 0.25
       merge_success: 0.45
       compliance: 0.15
       branch_health: 0.15
   ```

1. **Baseline mismatch**: Your team's patterns differ from defaults

   - Consider customizing thresholds for your specific workflow
   - File an issue to discuss adjusting default values

1. **Edge case bug**: Report with full context

   - Include: git metrics, efficiency score calculation, expected vs actual recommendations

### Q: Agent is not getting boosted based on my git metrics. Why?

**Symptoms**: Low merge success but `refactoring-agent` isn't prioritized, or similar issues.

**Diagnosis Steps**:

```bash
# 1. Verify git metrics collection
python -c "
from crackerjack.config import settings
print(f'Git metrics enabled: {settings.git_metrics.enabled}')
print(f'Workflow optimization enabled: {settings.workflow_optimization.enabled}')
"

# 2. Check agent boosting logic
# In crackerjack/intelligence/agent_orchestrator.py
# Look for _apply_workflow_boosts() method
grep -r "apply_workflow_boosts" crackerjack/

# 3. Enable debug logging
CRACKERJACK_DEBUG=1 python -m crackerjack run --run-tests 2>&1 | grep -i "boost"
```

**Common Solutions**:

1. **Both subsystems must be enabled**:

   ```yaml
   git_metrics:
     enabled: true  # Required
   workflow_optimization:
     enabled: true  # Required
   ```

1. **Metric threshold not met**: Boosting only occurs when metrics cross thresholds

   ```python
   # Example thresholds
   if merge_success_rate < 0.7:  # Must be below 70%
       boosted_agents.append("refactoring-agent")
   ```

1. **Agent not in boost mapping**: Check if the agent exists in the boost map

   ```python
   # In agent_orchestrator.py, verify agent exists in WORKFLOW_BOOSTS
   WORKFLOW_BOOSTS = {
       "low_merge_success": ["refactoring-agent", "test-specialist-agent"],
       "low_compliance": ["documentation-agent"],
       # Add new mappings here
   }
   ```

### Q: Can I use workflow optimization without session-buddy?

**Answer**: No, workflow optimization requires session-buddy for persistent storage. Git metrics and efficiency scores are stored in `.session-buddy/session_metrics.db`. However, session-buddy is included as a dependency of Crackerjack, so it's available automatically once installed.

```bash
# Verify session-buddy is installed
python -c "import session_buddy; print(session_buddy.__version__)"

# Check database exists
ls -la .session-buddy/session_metrics.db
```

______________________________________________________________________

## Integration with Session-Buddy

Workflow optimization leverages session-buddy's storage and analytics capabilities to provide persistent metrics tracking and cross-session insights. This integration enables trend analysis, historical comparisons, and data-driven decision making that spans multiple development sessions.

### Data Storage Model

Git metrics are stored in the `session_metrics` table in session-buddy's SQLite database:

```sql
CREATE TABLE session_metrics (
    session_id TEXT PRIMARY KEY,
    session_end TIMESTAMP,
    workflow_efficiency_score REAL,
    commit_velocity REAL,
    merge_success_rate REAL,
    compliance_rate REAL,
    active_branch_count INTEGER,
    branch_lifetime_avg REAL,
    -- Additional metrics...
    FOREIGN KEY (session_id) REFERENCES sessions(id)
);
```

This schema links git metrics directly to session data, enabling rich queries and analytics across both dimensions.

### Viewing Workflow Insights

Session-buddy provides a built-in dashboard for visualizing workflow trends:

```bash
# Launch session-buddy dashboard
python -m session_buddy dashboard

# Navigate to "Workflow Optimization" section
# View charts showing:
# - Workflow efficiency over time
# - Commit velocity trends
# - Merge success rate history
# - Compliance rate improvements
```

**Key Dashboard Features**:

- **Trend Visualization**: Line charts showing all metrics over time
- **Correlation Analysis**: See how changes in one metric affect others
- **Percentile Rankings**: Compare your metrics against team averages
- **Recommendation History**: Track which recommendations were generated and their impact
- **Session Details**: Drill down into specific sessions to understand outliers

### Cross-Session Analytics

Query session-buddy directly for custom analytics:

```sql
-- Find your most productive sessions (highest efficiency)
SELECT
    sm.session_id,
    sm.session_end,
    sm.workflow_efficiency_score,
    sm.commit_velocity,
    s.duration_seconds
FROM session_metrics sm
JOIN sessions s ON sm.session_id = s.id
WHERE sm.workflow_efficiency_score >= 80
ORDER BY sm.workflow_efficiency_score DESC
LIMIT 10;

-- Analyze day-of-week patterns
SELECT
    strftime('%w', session_end) as day_of_week,
    AVG(workflow_efficiency_score) as avg_efficiency,
    AVG(commit_velocity) as avg_velocity,
    COUNT(*) as session_count
FROM session_metrics
WHERE session_end >= date('now', '-90 days')
GROUP BY day_of_week
ORDER BY day_of_week;

-- Compare before/after implementing a change
SELECT
    CASE
        WHEN session_end < '2025-02-01' THEN 'Before'
        ELSE 'After'

### Integration Benefits

The session-buddy integration provides several key advantages:

1. **Persistent History**: Metrics survive across sessions, machines, and Crackerjack updates
1. **Trend Analysis**: Identify patterns that only emerge over weeks or months
1. **Correlation Insights**: Discover relationships between practices and outcomes
1. **Team Analytics**: Aggregate data across multiple developers (if using shared database)
1. **Custom Dashboards**: Build visualizations tailored to your team's needs

For teams working in shared repositories, consider centralizing session-buddy data collection to enable team-wide workflow insights and healthy competition around efficiency improvements.

## Best Practices

Based on analysis of high-performing teams using Crackerjack's workflow optimization, these practices consistently correlate with improved workflow efficiency scores and faster delivery.

### Commit Practices

- **Use Conventional Commits**: Follow `type(scope): description` format consistently

  ```
  feat(auth): add OAuth2 login support
  fix(api): resolve timeout issue in user endpoint
  test(user): add integration tests for password reset
  docs(readme): update installation instructions
  refactor(db): extract query builder into separate module
  ```

- **Commit Frequently but Logically**: Aim for 2-4 commits per hour during active development

  - Small, focused commits are easier to review and revert
  - Each commit should pass tests and be merge-ready
  - Use `git commit --amend` to consolidate related changes before pushing

- **Write Meaningful Messages**: Focus on "why" not "what"

  ```
  ❌ Bad: "fix stuff", "update", "wip"
  ✅ Good: "fix(auth): resolve token expiration race condition"
  ```

### Branch Management

- **Keep Branches Short-Lived**: Target maximum 3-5 days per branch

  ```bash
  # Check branch age regularly
  git for-each-ref --sort=-committerdate refs/heads/ \
    --format='%(refname:short) %(committerdate:relative)'
  ```

- **Merge Early, Merge Often**: Integrate changes at least daily

  - Reduces merge conflict frequency
  - Enables faster feedback loops
  - Prevents integration debt accumulation

- **Use Feature Flags for Incomplete Work**: Merge code behind flags instead of long-lived branches

  ```python
  # Example: Feature flag pattern
  if feature_flags.is_enabled("new-ui"):
      return render_new_ui()
  return render_legacy_ui()
  ```

### Quality Practices

- **Maintain High Test Coverage**: Aim for >80% coverage to catch integration issues early

  ```bash
  # Run tests before every commit
  python -m pytest --cov=crackerjack --cov-fail-under=80
  ```

- **Pre-Merge Testing Checklist**: Standardize quality checks

  ```bash
  # Automated pre-merge workflow
  python -m crackerjack run --run-tests -c --ai-fix
  ```

- **Code Review Guidelines**: Review within 24 hours of request

  - Focus on logic, design, and maintainability
  - Use automated tools for style and formatting
  - Approve or request changes promptly to avoid bottlenecks

### Monitoring and Response

- **Address CRITICAL Issues Within 24 Hours**: Don't let workflow problems fester

  - Set up alerts for efficiency score dropping below 40
  - Create incident response process for merge failures
  - Document root causes and prevention measures

- **Review Trends Weekly**: Check efficiency score trajectory

  ```bash
  # Weekly efficiency review
  sqlite3 .session-buddy/session_metrics.db \
    "SELECT date(session_end), workflow_efficiency_score
     FROM session_metrics
     WHERE session_end >= date('now', '-7 days')
     ORDER BY session_end;"
  ```

- **Celebrate Improvements**: Acknowledge positive changes

  - Share efficiency gains in team standups
  - Document successful practices for future reference
  - Reward consistent high performers

### Team Practices

- **Establish Team Standards**: Document and enforce consistent practices

  - Shared commit message guidelines
  - Branch naming conventions
  - Code review expectations
  - Definition of "ready to merge"

- **Regular Workflow Audits**: Review practices monthly

  - Analyze team-wide efficiency trends
  - Identify best practices to share
  - Address systemic issues collaboratively

- **Experiment and Iterate**: Try new practices based on data

  - A/B test different branch strategies
  - Measure impact of process changes
  - Adapt recommendations to your context

### Common Anti-Patterns to Avoid

- ❌ **"Merge Day" Batching**: Waiting until end of sprint to integrate all changes
- ❌ **Giant Feature Branches**: Branches living for weeks or months
- ❌ **"WIP" Commits**: Vague commit messages that don't explain intent
- ❌ **Ignoring Recommendations**: Dismissing workflow insights without consideration
- ❌ **Chasing Score Over Substance**: Gaming metrics instead of addressing root issues
- ❌ **One-Person Silos**: Single developer owning a branch for too long
- ❌ **Reactive Firefighting**: Only addressing CRITICAL issues, ignoring MEDIUM/HIGH

### Continuous Improvement Mindset

Workflow optimization is not a one-time fix but an ongoing practice. The most successful teams:

1. **Start with Awareness**: Enable metrics collection and observe baseline
1. **Identify Quick Wins**: Address HIGH and MEDIUM recommendations first
1. **Build Momentum**: Use early wins to justify investing in deeper improvements
1. **Institutionalize Learning**: Document what works and share across teams
1. **Iterate Continuously**: Regularly review and refine practices based on data

Remember: The goal is not a perfect efficiency score but a sustainable, productive workflow that enables your team to deliver value consistently. Use Crackerjack's recommendations as guidance, not commandments, and adapt them to fit your unique context and constraints.
