Triggers: templates, validation, reusable, shared, patterns
  Reusable patterns and templates for Claude Code skill and hook development.

  Triggers: validation patterns, error handling, testing templates, workflow patterns,
  shared patterns, reusable templates, DRY patterns, common workflows

  Use when: creating new skills or hooks that need consistent patterns, implementing
  validation logic, setting up error handling, creating test scaffolding,
  referencing standard workflow structures

  DO NOT use when: pattern is specific to one skill only.
  DO NOT use when: pattern is still evolving - wait for stability.
  DO NOT use when: pattern is context-dependent requiring variations.

  Reference these patterns to validate consistency across the ecosystem.

# Shared Patterns

Reusable patterns and templates for skill and hook development.

## Purpose

This skill provides shared patterns that are referenced by other skills in the abstract plugin. It follows DRY principles by centralizing common patterns.

## Pattern Categories

### Validation Patterns

See [modules/validation-patterns.md](modules/validation-patterns.md) for:
- Input validation templates
- Schema validation patterns
- Error reporting formats

### Error Handling

See [modules/error-handling.md](modules/error-handling.md) for:
- Exception hierarchies
- Error message formatting
- Recovery strategies

### Testing Templates

See [modules/testing-templates.md](modules/testing-templates.md) for:
- Unit test scaffolding
- Integration test patterns
- Mock fixtures

### Workflow Patterns

See [modules/workflow-patterns.md](modules/workflow-patterns.md) for:
- Checklist templates
- Feedback loop patterns
- Progressive disclosure structures

## Usage

Reference these patterns from other skills:

```markdown
For validation patterns, see the `shared-patterns` skill's
[validation-patterns](../shared-patterns/modules/validation-patterns.md) module.
```
**Verification:** Run the command with `--help` flag to verify availability.
## Troubleshooting

### Common Issues

**Command not found**
Ensure all dependencies are installed and in PATH

**Permission errors**
Check file permissions and run with appropriate privileges

**Unexpected behavior**
Enable verbose logging with `--verbose` flag
