# Sandbox Build (Read-Only)

Build and test in sandbox mode without modifying any files.

## Purpose
- Verify build status without changes
- Explore build errors safely
- Test configurations
- Validate before making changes

## Constraints
**DO NOT modify any files in sandbox mode.**

This skill is for observation and analysis only.

## Workflow

### 1. Check Project Status
```bash
# Check for uncommitted changes
git status

# List modified files
git diff --name-only
```

### 2. Build Verification
```bash
# Attempt build
xcodebuild build \
  -scheme MyApp \
  -destination 'platform=iOS Simulator,name=iPhone 15' \
  2>&1 | tee /tmp/build_output.txt
```

### 3. Test Verification
```bash
# Run tests without modifying
xcodebuild test \
  -scheme MyApp \
  -destination 'platform=iOS Simulator,name=iPhone 15' \
  -resultBundlePath /tmp/TestResults.xcresult \
  2>&1 | tee /tmp/test_output.txt
```

### 4. Analyze Results

Review build/test output and report:
- Build status (success/failure)
- Number of warnings
- Number of errors (with details)
- Test results summary
- Recommendations for fixes

### 5. Report Format

```markdown
## Sandbox Build Report
