Code Review

Reviewing the PR for issues that need fixing:

Todo List

• Read and analyze main command file
• Review test file for coverage and quality
• Check utility functions and error handling
• Verify dependencies and imports
• Identify actionable issues

Issues Found

Issue 1: Template injection vulnerability

• Lines 57-60 in create-aspect.ts: User input is directly interpolated into TypeScript template without validation
• The name and title values could contain characters that break the generated code (quotes, backticks, etc.)
• Fix: Add input sanitization before template generation

Issue 2: Test/implementation mocking inconsistency

• Implementation uses fileExists() utility (line 50) but tests mock access() directly (line 34)
• Since fileExists wraps access, tests should mock fileExists instead
• Fix: Change test to mock fileExists from @sanity/cli-core rather than access
