Update Gitignore

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.

Automated summary

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.

How this analysis is made

Examples

Ignore node_modules
Add node_modules/ to .gitignore and untrack it if already tracked.
Ignore environment files
Add .env and .env.local to .gitignore with a comment explaining they contain secrets.
Ignore build output
Add dist/ folder to .gitignore and check if any files inside were already tracked.

Update Gitignore

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

Instructions

  1. 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>.

  2. 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.

  3. Untrack (if needed):

    • If the file was already tracked, run git rm --cached <path> to stop tracking it while keeping the local copy.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/update-gitignore-mmbizkmv/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/update-gitignore-mmbizkmv' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/update-gitignore-mmbizkmv/download' --output '.skill-downloads/update-gitignore-mmbizkmv/SKILL.md.part' && mv '.skill-downloads/update-gitignore-mmbizkmv/SKILL.md.part' '.skill-downloads/update-gitignore-mmbizkmv/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/update-gitignore-mmbizkmv'

openskills read 'update-gitignore-mmbizkmv'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/update-gitignore-mmbizkmv/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
