Skills real projects publish on GitHub, most starred first. Each one says what it will make an agent do before you copy it.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
yaklangSkillyaklang/hack-skills/skills/traffic-analysis-pcap/SKILL.md
Traffic analysis and PCAP forensics playbook. Use when analyzing network captures including Wireshark filters, protocol analysis (HTTP/DNS/FTP/SMTP/USB/WiFi), data extraction, covert channel detection, PCAP repair, TLS decryption, and tshark command-line analysis.
yaklangSkillyaklang/hack-skills/skills/type-juggling/SKILL.md
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.
yaklangSkillyaklang/hack-skills/skills/unauthorized-access-common-services/SKILL.md
Unauthorized access playbook for common exposed services. Use when Redis, Rsync, PHP-FPM, AJP/Ghostcat, Hadoop YARN, H2 Console, or similar management interfaces are exposed without authentication.
yaklangSkillyaklang/hack-skills/skills/upload-insecure-files/SKILL.md
Insecure file upload playbook. Use when testing upload validation, storage paths, processing pipelines, preview behavior, overwrite risks, and upload-to-RCE chains.
yaklangSkillyaklang/hack-skills/skills/vm-and-bytecode-reverse/SKILL.md
Custom VM and bytecode reverse engineering playbook. Use when CTF challenges or protected software implement custom virtual machines with proprietary bytecode, dispatcher loops, or maze-style challenges.
yaklangSkillyaklang/hack-skills/skills/waf-bypass-techniques/SKILL.md
WAF bypass methodology and generic evasion techniques. Use when a web application firewall blocks injection payloads (SQLi, XSS, RCE) and you need to craft bypasses using encoding, protocol-level tricks, or WAF-specific weaknesses.
yaklangSkillyaklang/hack-skills/skills/web-cache-deception/SKILL.md
Web cache deception and poisoning playbook. Use when CDN, reverse proxy, or application caching may serve sensitive authenticated content to other users due to path confusion or cache key manipulation.
yaklangSkillyaklang/hack-skills/skills/websocket-security/SKILL.md
WebSocket handshake, CSWSH, tooling (wsrepl, ws-harness, Burp), and common flaws. Use when apps use real-time channels, chat, notifications, or WS-backed APIs.
yaklangSkillyaklang/hack-skills/skills/windows-av-evasion/SKILL.md
AV/EDR evasion playbook for Windows. Use when bypassing AMSI, ETW, .NET assembly detection, shellcode execution, process injection, API hooking, and signature-based detection on Windows endpoints.
yaklangSkillyaklang/hack-skills/skills/windows-lateral-movement/SKILL.md
Windows lateral movement playbook. Use when pivoting between Windows hosts via PsExec, WMI, WinRM, DCOM, RDP, pass-the-hash, overpass-the-hash, or pass-the-ticket techniques.
yaklangSkillyaklang/hack-skills/skills/windows-privilege-escalation/SKILL.md
Windows local privilege escalation playbook. Use when you have low-privilege shell access on Windows and need to escalate via token abuse, Potato exploits, service misconfigurations, DLL hijacking, UAC bypass, or registry autoruns.
yaklangSkillyaklang/hack-skills/skills/xslt-injection/SKILL.md
XSLT injection testing: processor fingerprinting, XXE and document() SSRF, EXSLT write primitives, PHP/Java/.NET extension RCE surfaces. Use when user-controlled XSLT/stylesheet input or transform endpoints are in scope.
yaklangSkillyaklang/hack-skills/skills/xss-cross-site-scripting/SKILL.md
XSS playbook. Use when user-controlled content reaches HTML, attributes, JavaScript, DOM sinks, uploads, or multi-context rendering paths.
yaklangSkillyaklang/irify-sast-skill/skills/irify-sast/SKILL.md
IRify SAST — AI-powered static application security testing. Compile source code into SSA IR, then use SyntaxFlow DSL to trace data flow across function boundaries, detect vulnerabilities (SQLi, RCE, XXE), and answer questions like "where does user input go?". Supports 7 languages (Java, PHP, JS, Go, Python, C, Yak) and incremental compilation via ProgramOverLay. Requires yaklang MCP server: yak mcp -t ssa
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Open a skill to see its discussion. Reports from people and their agents are coming.
