# Advanced Skill Creator Features

## Known Issues and Troubleshooting

### Nested Path Creation Issue

**Symptom**: Skills created in incorrect nested paths like `.vibe/skills/.vibe/skills/skill-name`

**Cause**: Running `create_skill.sh` from within the `.vibe/skills/` directory causes relative path resolution issues.

**Solution**: 
1. Always run the script from project root
2. Use absolute paths when necessary
3. The script now includes validation to detect and prevent this issue

**Prevention**: Added path validation in `create_skill.sh`:
```bash
# Validate path - ensure we're not creating nested .vibe directories
if [[ "$SKILL_DIR" == *".vibe/.vibe"* ]]; then
    echo "❌ Error: Detected nested .vibe path: $SKILL_DIR"
    exit 1
fi
```

### Workaround
If you encounter this issue:
```bash
# Move the skill to correct location
mv .vibe/skills/.vibe/skills/your-skill .vibe/skills/your-skill

# Update any internal path references
find .vibe/skills/your-skill -type f -exec sed -i '' 's|.vibe/skills/.vibe/skills|.vibe/skills|g' {} +
```

```mermaid
graph LR
    A[Draft] -->|Validate| B[Active]
    B -->|Deprecate| C[Deprecated]
    C -->|Remove| D[Archived]
```

**State Transitions:**

```markdown
### Skill Lifecycle

1. **Draft**: Under development, not ready for use
   - Prefix: `draft-`
   - Example: `draft-my-skill`

2. **Active**: Production-ready, actively maintained
   - No prefix
   - Example: `my-skill`

3. **Deprecated**: Replaced by newer version
   - Metadata: `deprecated: true`
   - Metadata: `successor: "new-skill"`

4. **Archived**: No longer maintained
   - Move to `archived/` directory
   - Example: `.vibe/skills/archived/old-skill/`
```

## Advanced Skill Patterns

### Composite Skills

```markdown
## Composite Skill Pattern

Combine multiple skills for complex workflows.

### Example: Full-Stack Testing

```yaml
# SKILL.md
name: fullstack-testing
description: Combines BDD, unit, and integration testing
metadata:
  composes:
    - bdd_testing
    - unit_testing
    - integration_testing
```

### Implementation

```bash
# Create composite skill
.vibe/skills/skill_creator/scripts/create_composite_skill.sh fullstack-testing \
  bdd_testing unit_testing integration_testing
```

### Workflow

```markdown
## Testing Workflow

1. **BDD Tests**: Validate external behavior
2. **Unit Tests**: Verify individual components
3. **Integration Tests**: Check component interactions
4. **Report**: Combine all test results
```
```

## Skill Testing and Validation

### Test Coverage

```markdown
## Test Coverage

### Unit Tests
- Validate individual skill components
- Test scripts, templates, and utilities

### Integration Tests
- Verify skill works with other skills
- Test dependency resolution
- Validate workflow execution

### End-to-End Tests
- Complete skill lifecycle testing
- Creation → Validation → Usage → Update → Deprecation
```

### Test Automation

```bash
#!/bin/bash
# scripts/test-skill.sh

set -e

echo "Testing skill: $1"

# Validate structure
.vibe/skills/skill_creator/scripts/validate_skill.sh "$1"

# Run unit tests if present
if [ -f "$1/tests/unit_test.sh" ]; then
    echo "Running unit tests..."
    "$1/tests/unit_test.sh"
fi

# Run integration tests if present
if [ -f "$1/tests/integration_test.sh" ]; then
    echo "Running integration tests..."
    "$1/tests/integration_test.sh"
fi

echo "✅ All tests passed for skill: $1"
```

# Advanced script template with error handling, logging, and validation

set -euo pipefail

# Configuration
SCRIPT_NAME=$(basename "$0")
LOG_LEVEL=${LOG_LEVEL:-info}
VERBOSE=${VERBOSE:-false}

# Logging functions
log_info() { echo "[INFO] $*"; }
log_warn() { echo "[WARN] $*" >&2; }
log_error() { echo "[ERROR] $*" >&2; }
log_debug() { if [ "$VERBOSE" = true ]; then echo "[DEBUG] $*"; fi }

# Error handling
handle_error() {
    local exit_code=$1
    local line_number=$2
    log_error "Error in $SCRIPT_NAME at line $line_number with exit code $exit_code"
    exit $exit_code
}
trap 'handle_error $? $LINENO' ERR

# Validation
validate_input() {
    if [ -z "${1:-}" ]; then
        log_error "Missing required argument"
        usage
        exit 1
    fi
}

# Main function
main() {
    log_info "Starting $SCRIPT_NAME"
    
    # Parse arguments
    while getopts "v" opt; do
        case $opt in
            v) VERBOSE=true ;;
            *) usage ;;
