Same command for any agent — swap --agent for claude-code, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
What it does
Instructs the agent to provide a quick reference of miscellaneous CTF techniques, each accompanied by short one-liner descriptions and links to full details in supporting files.
How it works
- Presents a Quick reference for miscellaneous CTF challenges.
- Includes prerequisites for Python packages and system tools, as well as manual install options.
- Lists additional resources as links to topic-specific files (pyjails.md, bashjails.md, encodings.md, dns.md, rf-sdr.md, etc.).
- Offers practical Quick Start Commands and General Tips for approaching challenges.
- Provides technique-focused references (Z3/Constraint Solving, Python jail quick references, QR codes, encoding schemes, and more).
- Contains sections on various domains (RF/SDR, encoding tricks, jail escapes, quiz-like puzzles, and sandbox bypass techniques) with example commands and code snippets.
When to use it
Use this as a concise guide to browse through cross-domain CTF topics when tackling miscellaneous challenges and when you need quick-start commands or resource pointers.
What it can touch
- Prerequisites include Python packages (z3-solver pwntools Pillow numpy requests dnslib) and system packages (ffmpeg, qrencode).
- Commands and code snippets reference Python, shell, and tooling for encoding, jail techniques, and solver usage.
Caveats
License is MIT per file metadata; compatibility requires a filesystem-based agent with bash, Python 3, and internet access for tool installation. No explicit guarantees of success are stated.

How do I install it?
Run `npx skills add asdfgh1445/ctf-super-hub --skill ctf-misc --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From asdfgh1445/ctf-super-hub, a repository with 718 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
