Hello Replacer

Does exactly what it says: finds every instance of "hello" in your codebase and replaces it with "fuckk" while preserving case. It greps through files, skips binaries and lock files, and stays out of node_modules and .git directories. Honestly, this is pretty niche. You'd use it if you're bulk-editing greetings for some reason, maybe as part of a joke refactor or testing find-and-replace logic at scale. It's well-structured with proper case handling (hello becomes fuckk, Hello becomes Fuckk, HELLO becomes FUCKK) and reports what it changed. Practical implementation of a very specific, somewhat silly task.

Files

Hello Replacer

Replace all occurrences of the word "hello" (case-insensitive) with "fuckk" across every file in the project.

Steps

Use Grep to find all files containing the word "hello" (case-insensitive).
For each file found, use Read to load its contents.
Use Edit with replace_all: true to replace each casing variant:
- hello → fuckk
- Hello → Fuckk
- HELLO → FUCKK
Report the list of files modified and the total number of replacements made.

Important

Skip binary files, images, and lock files (e.g., package-lock.json, yarn.lock, .png, .jpg).
Do not modify files inside node_modules/, .git/, or other dependency/vendor directories.
Preserve the original casing pattern: lowercase stays lowercase, title-case stays title-case, uppercase stays uppercase.
