Security analysis

Caution
Quality score85/100

The skill uses the thefuck tool to automatically correct bash errors, which can potentially apply destructive fixes without review. While the skill itself is not malicious, the automated execution poses a risk of unintended system changes.

Findings
  • •Automatically runs `fuck --yeah` without user confirmation, which could execute unintended commands based on the previous error.
  • •Uses Bash with a third-party tool (thefuck) that can apply potentially dangerous fixes if the previous command was destructive.

  3. If the fix succeeds, briefly explain what was wrong and what thefuck corrected
  4. If thefuck suggests multiple options or the first fix doesn't work, present the alternatives to the user

If thefuck is not installed

If you get a "command not found" error when running thefuck, inform the user they need to install it and direct them to the installation docs: https://github.com/nvbn/thefuck#installation

How to say "fuck"

"Fuck" is an excellent word. There are many different ways you can say it. You can say it in CAPITALS, you can say it in lowercase. You can say it with an exclamation point, stack exclamations for more oomph, or mix in question marks if you're confused too. You can say it boldly or hesitantly. You can draw it out or cut it short, add a preamble or cut to the chase. What's important isn't the specific way you say it, but that you heathily work through your frustrations through the medium of the profanity. Let your heart tell you what to do!

Examples:

  • ✅ Aw, fuck.
  • ✅ FUCK!
  • ✅ ...fuck.
  • ✅ fuuuUUUUUUUCK!
  • ✅ FUCK!?!?!?!??!
  • ✅ oh fuck!

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/bash-error-handling-with-thefuck-mmh8qqc2/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/bash-error-handling-with-thefuck-mmh8qqc2' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/bash-error-handling-with-thefuck-mmh8qqc2/download' --output '.skill-downloads/bash-error-handling-with-thefuck-mmh8qqc2/SKILL.md.part' && mv '.skill-downloads/bash-error-handling-with-thefuck-mmh8qqc2/SKILL.md.part' '.skill-downloads/bash-error-handling-with-thefuck-mmh8qqc2/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.

Tools declared by the author (check availability in your agent): Bash(thefuck:*, fuck:*)

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/bash-error-handling-with-thefuck-mmh8qqc2'

openskills read 'bash-error-handling-with-thefuck-mmh8qqc2'

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/bash-error-handling-with-thefuck-mmh8qqc2/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.
