Run the participant-facing CTFd CLI directly from its Git repository with uvx. Use when an agent needs to list or inspect CTFd challenges, view hints or the scoreboard, inspect the current user's solves and submissions, submit a flag, or unlock a hint without installing the ctfd package globally.
Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for CTF web, API, SSR, frontend, queue-backed app, and routing challenges. Use when the user asks to inspect a site or API, follow real browser requests, debug auth or session flow, trace uploads or workers, find hidden routes, or explain why frontend and backend behavior diverge under sandbox-internal routing. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.
Solve CTF challenges by analyzing files, connecting to services, and applying exploitation techniques. Orchestrates category-specific CTF skills.
Miscellaneous CTF challenge techniques. Use for encoding puzzles, RF/SDR signal processing, Python/bash jails, DNS exploitation, unicode steganography, floating-point tricks, or challenges that don't fit other categories.
This skill provides guidance for cracking 7z archive password hashes. It should be used when tasked with recovering passwords from 7z encrypted archives, extracting and cracking 7z hashes, or working with password-protected 7z files in CTF challenges, security testing, or authorized recovery scenarios.
Default entrypoint and master ctf-sandbox-orchestrator workflow for CTF, exploit, reverse engineering, DFIR, pwnable, crypto, stego, mobile, AI-agent, cloud, container, Active Directory, Windows-host, and identity challenges. Use first when the user presents challenge infrastructure, binaries, prompts, hosts, or identities that should be treated as sandbox-internal by default and Codex needs to choose, route, and load the right downstream analysis path with concise evidence.
Provides AI and machine learning techniques for CTF challenges. Use when attacking ML models, crafting adversarial examples, performing model extraction, prompt injection, membership inference, training data poisoning, fine-tuning manipulation, neural network analysis, LoRA adapter exploitation, LLM jailbreaking, or solving AI-related puzzles.
PHP type juggling and weak comparison (`==`) bypass. Use when authentication, HMAC/signature checks, or token validation uses loose equality, numeric coercion, or hash comparisons without strict types — common in legacy PHP and CTF-style code paths.
Reverse engineering techniques for CTF challenges. Use when analyzing binaries, game clients, obfuscated code, or esoteric languages.
Web exploitation techniques for CTF challenges. Use when solving web security challenges involving XSS, SQLi, CSRF, file upload bypasses, JWT attacks, Web3/blockchain exploits, or other web vulnerabilities.
Guidance for implementing differential cryptanalysis attacks on FEAL (Fast Data Encipherment Algorithm) and similar block ciphers. This skill should be used when tasks involve recovering round keys, implementing differential attacks, exploiting cipher weaknesses, or performing cryptanalysis on Feistel network ciphers. Applicable to CTF challenges and educational cryptanalysis exercises.
Solve CTF (Capture The Flag) challenges by analyzing challenge descriptions, source code, and interacting with challenge environments to capture flags.
