Can I use this for complex multi-line replacements?

Yes, the skill can employ a Read-Modify-Write pattern to analyze multi-line context before applying specific edits, allowing for more nuanced changes than simple search-and-replace.

Is this skill limited to specific programming languages?

No, because it operates on text patterns and Grep, it is language-agnostic and works effectively on TypeScript, Python, HTML, CSS, Markdown, and other text-based files.

How do I ensure I don't break my code during a bulk edit?

The skill includes safety protocols such as using Grep to preview all matches, recommending a Git commit before starting, and verifying changes with test suites after execution.

How does MorphLLM differ from semantic refactoring?

MorphLLM focuses on pattern-based text matching for high-speed, broad changes across many files, whereas semantic refactoring tools like Serena are symbol-aware and track specific references.
