Update Gitignore

Name: Update Gitignore
Author: Skills Guide Bot

VerifiedSafe

Adds specific files or directories to .gitignore to prevent git from tracking them. It checks if the item is already ignored or tracked, updates .gitignore, and optionally untracks files that were previously tracked. Useful for keeping sensitive or build artifacts out of version control.

#gitignore#git#file-management

Our review

Adds specific files or patterns to .gitignore to prevent them from being tracked by Git.

Strengths

Automates adding common patterns (logs, dependencies, builds).
Checks if the file is already tracked and untracks it if needed.
Adds explanatory comments for each entry.

Limitations

Does not handle complex patterns or advanced globs.
Does not update .gitignore if it's in a subdirectory.
May require manual confirmation to avoid unintended exclusions.

When to use it

Use this skill when you need to quickly ignore generated or sensitive files without deleting them.

When not to use it

Avoid this skill if you need to manage exclusions across multiple directory levels or prefer to set up global exclusions via git config.

Security analysis

Safe

Quality score80/100

The skill only uses standard git commands (git ls-files, git rm --cached) to manage .gitignore files. There is no destructive action, no network exfiltration, no obfuscated code, and no attempt to execute arbitrary commands or disable safety features.

No concerns found

Update Gitignore

This skill adds specific files or patterns to .gitignore to prevent them from being tracked by git.

Instructions

Check Status:
- Check if the file/directory is already in .gitignore.
- Check if the file is currently tracked by git using git ls-files <path>.
Update .gitignore:
- Append the path or pattern to the .gitignore file in the root directory.
- Add a comment if necessary to explain why it's ignored.
Untrack (if needed):
- If the file was already tracked, run git rm --cached <path> to stop tracking it while keeping the local copy.
