name: shared-patterns description: 'Reference these patterns to validate consistency across the ecosystem. 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.' category: meta-infrastructure tags:

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 for:

• Input validation templates
• Schema validation patterns
• Error reporting formats

Error Handling

See modules/error-handling.md for:

• Exception hierarchies
• Error message formatting
• Recovery strategies

Testing Templates

See modules/testing-templates.md for:

• Unit test scaffolding
• Integration test patterns
• Mock fixtures

Workflow Patterns

See modules/workflow-patterns.md for:

• Checklist templates
• Feedback loop patterns
• Progressive disclosure structures

Usage

Reference these patterns from other skills:

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
