+description: Check current sprint progress and identify blockers
+---
+
+# Sprint Status Check
+
+This command provides a quick overview of your current sprint progress, including open issues, completed work, and potential blockers.
+
+## What This Command Does
+
+1. **Fetch Sprint Issues** - Lists all issues with current sprint labels/milestone
+2. **Categorize by Status** - Groups issues into: Open, In Progress, Blocked, Completed
+3. **Identify Blockers** - Highlights issues with blocker comments or dependencies
+4. **Show Progress Summary** - Provides completion percentage and velocity insights
+5. **Highlight Priorities** - Shows critical and high-priority items needing attention
+
+## Usage
+
+Simply run `/sprint-status` to get a comprehensive sprint overview.
+
+## MCP Tools Used
+
+This command uses the following Gitea MCP tools:
+
+- `list_issues(state="open")` - Fetch open issues
+- `list_issues(state="closed")` - Fetch completed issues
+- `get_issue(number)` - Get detailed issue information for blockers
+
+## Expected Output
+
+```
+Sprint Status Report
+====================
+
+Sprint: Sprint 16 - Authentication System
+Date: 2025-01-18
+
+Progress Summary:
+- Total Issues: 8
+- Completed: 3 (37.5%)
+- In Progress: 2 (25%)
+- Open: 2 (25%)
+- Blocked: 1 (12.5%)
+
+Completed Issues (3):
+✅ #45: Implement JWT token generation [Type/Feature, Priority/High]
+✅ #46: Build user login endpoint [Type/Feature, Priority/High]
+✅ #48: Write authentication tests [Type/Test, Priority/Medium]
+
+In Progress (2):
+🔄 #47: Create user registration form [Type/Feature, Priority/Medium]
+🔄 #49: Add password reset flow [Type/Feature, Priority/Low]
+
+Open Issues (2):
+📋 #50: Integrate OAuth providers [Type/Feature, Priority/Low]
+📋 #51: Add email verification [Type/Feature, Priority/Medium]
+
+Blocked Issues (1):
+🚫 #52: Deploy auth service [Type/Deploy, Priority/High]
+   Blocker: Waiting for database migration approval
+
+Priority Alerts:
+⚠️  1 high-priority item blocked: #52
+✅ All critical items completed
+
+Recommendations:
+1. Focus on unblocking #52 (Deploy auth service)
+2. Continue work on #47 (User registration form)
+3. Consider starting #51 (Email verification) next
+```
+
+## Filtering Options
+
+You can optionally filter the status check:
+
+**By Label:**
+```
+Show only high-priority issues:
+list_issues(labels=["Priority/High"])
+```
+
+**By Milestone:**
+```
+Show issues for specific sprint:
+list_issues(milestone="Sprint 16")
+```
+
+**By Component:**
+```
+Show only backend issues:
+list_issues(labels=["Component/Backend"])
+```
+
+## Blocker Detection
+
+The command identifies blocked issues by:
+1. Checking issue comments for keywords: "blocked", "blocker", "waiting for", "dependency"
+2. Looking for issues with no recent activity (>7 days)
+3. Identifying issues with unresolved dependencies
+
+## When to Use
+
+Run `/sprint-status` when you want to:
+- Start your day and see what needs attention
+- Prepare for standup meetings
+- Check if the sprint is on track
+- Identify bottlenecks or blockers
+- Decide what to work on next
+
+## Integration with Other Commands
+
+- Use `/sprint-start` to begin working on identified tasks
+- Use `/sprint-close` when all issues are completed
+- Use `/sprint-plan` to adjust scope if blocked items can't be unblocked
+
