# Sprint Planning Workflow

## Overview
Help the team plan their next sprint by reviewing backlog items and updating statuses.

## Steps

1. **Review Backlog**
   - Use \`jira_get_issue\` to fetch backlog items
   - Analyze priority and estimates

2. **Assign to Sprint**
   - Use \`jira_update_status\` to move items to sprint
   - Verify capacity constraints

3. **Notify Team**
   - Use \`slack_notify\` to inform the team
   - Share sprint goals and assignments

## Best Practices
- Keep sprint scope realistic
- Balance workload across team members
- Leave buffer for unexpected work
