# Verify Epic Completion

Verifies that a beads epic is complete by:
1. Checking all child features are closed
2. Executing the build system `verify` target for epic scope
3. Running comprehensive cross-feature validation

## Usage

```bash
# Verify epic
/bkff:verifyepic --issue=beads-abc123

# Output as JSON
/bkff:verifyepic --issue=beads-abc123 --format=json
```

## Verification Process

1. **Acceptance Criteria Check**: Epic must have defined acceptance criteria
2. **Child Features Check**: All child features must be in 'closed' status
3. **Verify Target**: Run comprehensive verification for epic scope

## What Gets Checked

The `verify` target at epic scope should run:

| Check Type | Description |
|------------|-------------|
| Cross-Feature Tests | Integration across all features |
| Epic Documentation | Epic-level documentation complete |
| System Integration | End-to-end system tests |
| All feature checks | Everything from feature verification |

## Output

### With Open Child Features
