description: "Advanced Scrum Master skill for data-driven agile team analysis and coaching. Use when the user asks about sprint planning, velocity tracking, retrospectives, standup facilitation, backlog grooming, story points, burndown charts, blocker resolution, or agile team health. Runs Python scripts to analyse sprint JSON exports from Jira or similar tools: velocity_analyzer.py for Monte Carlo sprint forecasting, sprint_health_scorer.py for multi-dimension health scoring, and retrospective_analyzer.py for action-item and theme tracking. Produces confidence-interval forecasts, health grade reports, and improvement-velocity trends for high-performing Scrum teams."

# Scrum Master Expert

Data-driven Scrum Master skill combining sprint analytics, probabilistic forecasting, and team development coaching. The unique value is in the three Python analysis scripts and their workflows — refer to `references/` and `assets/` for deeper framework detail.

## Analysis Tools & Usage

### 1. Velocity Analyzer (`scripts/velocity_analyzer.py`)

Runs rolling averages, linear-regression trend detection, and Monte Carlo simulation over sprint history.

```bash
# Text report
python velocity_analyzer.py sprint_data.json --format text

# JSON output for downstream processing
python velocity_analyzer.py sprint_data.json --format json > analysis.json
```

**Outputs**: velocity trend (improving/stable/declining), coefficient of variation, 6-sprint Monte Carlo forecast at 50 / 70 / 85 / 95% confidence intervals, anomaly flags with root-cause suggestions.

**Validation**: If fewer than 3 sprints are present in the input, stop and prompt the user: *"Velocity analysis needs at least 3 sprints. Please provide additional sprint data."* 6+ sprints are recommended for statistically significant Monte Carlo results.

---

### 2. Sprint Health Scorer (`scripts/sprint_health_scorer.py`)

Scores team health across 6 weighted dimensions, producing an overall 0–100 grade.

| Dimension | Weight | Target |
|---|---|---|
| Commitment Reliability | 25% | >85% sprint goals met |
| Scope Stability | 20% | <15% mid-sprint changes |
| Blocker Resolution | 15% | <3 days average |
| Ceremony Engagement | 15% | >90% participation |
| Story Completion Distribution | 15% | High ratio of fully done stories |
| Velocity Predictability | 10% | CV <20% |

```bash
python sprint_health_scorer.py sprint_data.json --format text
```

**Outputs**: overall health score + grade, per-dimension scores with recommendations, sprint-over-sprint trend, intervention priority matrix.

**Validation**: Requires 2+ sprints with ceremony and story-completion data. If data is missing, report which dimensions cannot be scored and ask the user to supply the gaps.

---

### 3. Retrospective Analyzer (`scripts/retrospective_analyzer.py`)

Tracks action-item completion, recurring themes, sentiment trends, and team maturity progression.

```bash
python retrospective_analyzer.py sprint_data.json --format text
```

**Outputs**: action-item completion rate by priority/owner, recurring-theme persistence scores, team maturity level (forming/storming/norming/performing), improvement-velocity trend.

**Validation**: Requires 3+ retrospectives with action-item tracking. With fewer, note the limitation and offer partial theme analysis only.
