name: pattern-finder description: Find implementation examples and design patterns in the codebase. Use when user asks "how to implement X", "how does this project do X", "show me examples of X", "where is X implemented", or needs to follow existing code conventions.

Pattern Finder

When to Use

Trigger this skill when the user:

• Asks how to implement a specific feature
• Wants to see existing implementation examples
• Needs to follow project conventions
• Asks "how does this project do X"
• Asks "show me examples of X"

Instructions

1. Identify what pattern the user is looking for
2. Run /sourceatlas:pattern "<pattern>" with the relevant pattern name
3. Returns best example files with line numbers and implementation guide

Common Patterns

• API endpoints: /sourceatlas:pattern "api endpoint"
• Authentication: /sourceatlas:pattern "authentication"
• Database queries: /sourceatlas:pattern "database query"
• Background jobs: /sourceatlas:pattern "background job"
• File uploads: /sourceatlas:pattern "file upload"
• Error handling: /sourceatlas:pattern "error handling"
• Validation: /sourceatlas:pattern "validation"
• Testing: /sourceatlas:pattern "unit test"

What User Gets

• Best example files with exact line numbers
• Standard implementation flow
• Key conventions to follow
• Common pitfalls to avoid
• Testing patterns

Example Triggers

• "How do I add a new API endpoint?"
• "Show me how authentication works here"
• "Where can I find examples of database queries?"
• "How does this project handle errors?"
