A Massive Collection of Codex Skills — After Translating It, I Found It Actually Useful

PS: Mainly for beginners — installation and demos.

A while back, I came across a collection of Codex skills called awesome-codex-skills.

awesome-codex-skills

awesome-codex-skills

It also works with Claude Code, Gemini CLI (random stuff sneaks in), and more.

I initially thought it was just another list of AI tools, but when I opened it, the content was surprisingly solid.

It already organizes a large number of skills by real-world use cases.

It splits the skills Codex can use into several categories:

• Development & Code Tools
• Productivity & Collaboration
• Communication & Writing
• Data & Analytics
• Metadata & Utilities

Most importantly, it also directly explains how to install and use these skills in Codex.

What exactly are skills?

In short:

Skills are pre-built capabilities for AI, made by others. Once you install them, you can use them directly.

And they’re completely open-source and free — nice.

If before, most of our AI interactions involved writing prompts,

want to analyze an industry → write an industry analysis prompt

want to research a competitor → write a competitor analysis prompt

want to generate a document → write yet another prompt

Start from scratch every time.

Skills are more like a ready-made workflow.

It includes not just prompts,

but also task breakdowns, execution steps, output formats,

and best practices for specific scenarios.

For example, first analyze Git history, then find hot files, risk areas, error-prone modules, then compile a report.

e.g., gh-fix-ci

gh-fix-ci

gh-fix-ci

It doesn’t just check for errors. It wraps the GitHub Actions troubleshooting process,

integrating log analysis, error localization, and fix suggestions into a complete workflow.

Another example: meeting-insights-analyzer

After you input meeting notes, it extracts topics, risks, and action items — rather than just generating a summary.

The more I looked, the more these skills felt like SOPs for teams.

When you do something for the first time, you need to research, hit obstacles, revise repeatedly.

Once a process works, someone captures that experience into a reusable skill.

Next time you face a similar task, you don’t have to rethink everything.

Just call the skill.

On the surface, it’s 1000+ skills.

But actually, it’s many developers, product managers, operators, and content creators who have distilled their regularly used workflows.

The categories I recommend most

The whole repo has thousands of skills.

If it’s your first time, I don’t suggest browsing them one by one.

Better to start from your own work scenarios.

Here are the categories I’m currently most interested in.

Data & Analytics

This was the first category I looked at.

Because many daily tasks are data-related.

Ad data, operations data, competitor data, SEO data, keyword data — it all eventually comes down to spreadsheets and analysis.

A few skills that caught my eye:

• spreadsheet-formula-helper
• competitive-ads-extractor
• developer-growth-analysis
• domain-name-brainstormer

Especially competitive-ads-extractor.

I plan to test it separately later.

If it can automatically dissect ad structures from Facebook, Instagram, or other platforms, it would be very helpful for content and ad teams.

Productivity & Collaboration

This category exceeded my expectations.

I thought it would just be project management tools.

But as I browsed, many addressed real work problems.

For example:

• meeting-insights-analyzer
• notion-research-documentation
• support-ticket-triage
• paperjsx

Especially paperjsx.

This skill can generate PPT, Word, Excel, and PDF from structured data.

For anyone who frequently does presentations, proposals, and reports, it’s pretty interesting.

Development & Code Tools

This category is the largest in the whole repo.

If you use Codex for coding, you’ll likely use these.

For example:

• codebase-recon
• gh-fix-ci
• webapp-testing
• codebase-migrate

In the past, when taking over a new project, I had to slowly read through the code.

The approach of codebase-recon is interesting.

It first analyzes the codebase, then tells you which files are most important, which areas are highest risk, which modules change most often.

For someone newly taking over a project, it saves a lot of time.

How to install

This part is split into three steps.

• Open Codex and create a new project
• Pull the project in Codex and install skills
• Use the skills

Open Codex

Project → New blank project

Name your new skills project: Awesome Skills

Model selection: Claude 5.4 Medium — since it’s just a simple pull, we don’t need high intelligence.

If it needs to install anything else along the way, you can let Codex handle it.

Just talk to it naturally — no technical expertise needed.

Don’t worry, Codex will take care of it.

I ran into an issue during installation — Codex simply refused to download.

(When will the network be stable?)

In that case, you can directly go to the repo and choose: Code → Download ZIP

Then just feed the files to Codex.

After installation, here’s what it looks like:

Usage:

There’s a skill in the repo called Development & Code Tools.

All you need to say is:

【Help me filter which skills are worth installing. I work in XXXXX】

Then the skill can automatically identify which content is worth installing.

If you don’t provide any context, the default skills look like the image below.

For example, my case:

I work in cross-border e-commerce.

My main needs are to analyze Facebook ads, write copy, create assets, choose products, and research landing pages.

What should I install?

Codex will directly tell you what to install.

After installation, usage:

Just copy a skill name — no symbols needed. The AI will understand what you mean.

Other skills work the same way.

The main logic:

Filter skills → Install skills → Use skills

If you have the ability, you can then modify and optimize the skills further.

Optimization works the same way:

Just tell Codex, I want to modify XXXX. The direction is: XXXXXX

Simple and clear.

Final thoughts

I haven’t finished browsing the entire repo yet.

I’ve only read the descriptions of many skills, haven’t actually integrated them into my own workflow.

But one thing left a deep impression on me.

Before, I mostly bookmarked tools.

When I saw a new tool,

I’d first register, then bookmark it, and then let it gather dust in my browser.

Now, I’m increasingly bookmarking workflows.

The same Codex,

some people always start from scratch, while others have already turned their common processes into skills.

Researching an industry has its own skill.

Analyzing ads has its own skill.

Writing articles has its own skill.

Building websites has its own skill.

Many repetitive tasks might take hours the first time.

But after you distill them, they might only take minutes later.

Over the next few days, I plan to install and test these skills one by one.

If there are any truly worth keeping long-term, I’ll write separate hands-on articles about them.

If you’re also using Codex,

this repo is worth bookmarking.

You might just find a few workflows that fit your needs.
