Explain
Provide a clear explanation of how something in the codebase works.
Instructions
- Identify what to explain: Use
$ARGUMENTSto determine the target
- File path → explain that file's purpose and how it works
- Function/class name → find and explain that specific code
- Feature name → trace through the codebase to explain the feature end-to-end
- Gather context
- Read the relevant code
- Identify dependencies and relationships
- Look at how it's used (callers, imports)
- Check for related tests that show intended behavior
- Explain clearly
- Start with a high-level summary (1-2 sentences)
- Break down the key components
- Explain the flow/logic step by step
- Note any important patterns or design decisions
- Mention edge cases or gotchas if relevant
Guidelines
- Adjust depth based on complexity—simple code needs brief explanations
- Use concrete examples from the code when helpful
- Reference specific line numbers for key logic
- If the target is ambiguous, ask for clarification
- Avoid restating code literally; explain the _why_ and _how_
