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/graphql-and-hidden-parameters/SKILL.md
GraphQL and hidden parameter testing playbook. Use when exploring introspection, batching, undocumented fields, hidden parameters, schema abuse, and GraphQL authorization gaps.
yaklangSkillyaklang/hack-skills/skills/hash-attack-techniques/SKILL.md
Hash attack playbook. Use when exploiting length extension, MD5/SHA1 collisions, HMAC timing leaks, birthday attacks, or hash-based proof of work in CTF and authorized testing scenarios.
yaklangSkillyaklang/hack-skills/skills/heap-exploitation/SKILL.md
Heap exploitation playbook. Use when targeting ptmalloc2/glibc heap vulnerabilities including UAF, double free, overflow, off-by-one/null, and leveraging tcache/fastbin/unsortedbin attacks for arbitrary write or code execution.
yaklangSkillyaklang/hack-skills/skills/http2-specific-attacks/SKILL.md
HTTP/2 protocol-specific attack playbook. Use when the target supports HTTP/2 and you need to exploit binary framing, HPACK compression, h2c upgrade smuggling, pseudo-header injection, stream multiplexing abuse, or H2→H1 downgrade translation flaws.
yaklangSkillyaklang/hack-skills/skills/http-host-header-attacks/SKILL.md
HTTP Host header injection and routing abuse playbook. Use when the application trusts the Host header for generating URLs, routing requests, or access control — enabling password reset poisoning, web cache poisoning, SSRF via routing, and virtual host bypass.
yaklangSkillyaklang/hack-skills/skills/http-parameter-pollution/SKILL.md
HTTP Parameter Pollution (HPP): duplicate query/body keys parsed differently by servers, proxies, WAFs, and app frameworks. Use when filters and application layers disagree on which value wins, enabling bypass, SSRF second URL, logic abuse, or CSRF token confusion.
yaklangSkillyaklang/hack-skills/skills/idor-broken-object-authorization/SKILL.md
IDOR and broken object authorization testing playbook. Use when requests expose object identifiers, tenant boundaries, writable fields, or missing object-level authorization checks.
yaklangSkillyaklang/hack-skills/skills/injection-checking/SKILL.md
Entry P1 category router for injection testing. Use when routing between XSS, SQLi, SSRF, XXE, SSTI, command injection, and NoSQL injection workflows based on how attacker-controlled input is consumed.
yaklangSkillyaklang/hack-skills/skills/ios-pentesting-tricks/SKILL.md
iOS pentesting playbook. Use when testing iOS applications for keychain extraction, URL scheme hijacking, Universal Links exploitation, runtime manipulation, binary protection analysis, data storage issues, and transport security bypass during authorized mobile security assessments.
yaklangSkillyaklang/hack-skills/skills/jndi-injection/SKILL.md
JNDI injection playbook. Use when Java applications perform JNDI lookups with attacker-controlled names, especially via Log4j2, Spring, or any code path reaching InitialContext.lookup().
yaklangSkillyaklang/hack-skills/skills/kernel-exploitation/SKILL.md
Linux kernel exploitation playbook. Use when exploiting kernel vulnerabilities (UAF, OOB, race condition, type confusion) for privilege escalation via commit_creds, modprobe_path overwrite, or kernel ROP chains in CTF and real-world scenarios.
yaklangSkillyaklang/hack-skills/skills/kubernetes-pentesting/SKILL.md
Kubernetes penetration testing playbook. Use when targeting Kubernetes clusters via API server, RBAC enumeration, service account abuse, etcd access, Kubelet API, pod escape, cloud-specific metadata, admission webhook bypass, and registry secrets.
yaklangSkillyaklang/hack-skills/skills/lattice-crypto-attacks/SKILL.md
Lattice-based cryptanalysis playbook. Use when attacking RSA via Coppersmith small roots, recovering DSA/ECDSA nonces from bias, solving knapsack problems, or applying LLL/BKZ reduction to cryptographic constructions.
yaklangPipes a download into a shellSkillyaklang/hack-skills/skills/linux-security-bypass/SKILL.md
Linux security mechanism bypass playbook. Use when facing restricted bash/rbash, read-only or noexec filesystems, AppArmor, SELinux, seccomp filters, or audit logging that must be evaded during post-exploitation.
yaklangPipes a download into a shellSkillyaklang/hack-skills/skills/llm-prompt-injection/SKILL.md
LLM prompt injection playbook. Use when testing AI/LLM applications for direct injection, indirect injection via RAG/browsing, tool abuse, data exfiltration, MCP security risks, and defense bypass techniques.
yaklangSkillyaklang/hack-skills/skills/macos-process-injection/SKILL.md
macOS process injection playbook. Use when you need to inject code into running or launching macOS processes via dylib hijacking, DYLD environment variables, XPC exploitation, Mach port manipulation, or Electron/Chromium abuse.
yaklangSkillyaklang/hack-skills/skills/macos-security-bypass/SKILL.md
macOS security bypass playbook. Use when targeting macOS endpoints and need to bypass TCC, Gatekeeper, SIP, sandbox, code signing, or entitlement-based protections during authorized red team or pentest engagements.
yaklangSkillyaklang/hack-skills/skills/memory-forensics-volatility/SKILL.md
Memory forensics playbook using Volatility 2/3. Use when analyzing memory dumps for malware analysis, credential extraction, process investigation, code injection detection, and incident response timeline reconstruction.
yaklangSkillyaklang/hack-skills/skills/mobile-ssl-pinning-bypass/SKILL.md
Mobile SSL pinning bypass playbook. Use when intercepting HTTPS traffic from mobile applications that implement certificate pinning, public key pinning, or SPKI hash pinning on Android and iOS, including React Native, Flutter, and Xamarin frameworks.
yaklangSkillyaklang/hack-skills/skills/network-protocol-attacks/SKILL.md
Network protocol attack playbook. Use when exploiting layer 2/3 protocols including ARP spoofing, LLMNR/NBT-NS/mDNS poisoning, WPAD abuse, DHCPv6 attacks, VLAN hopping, STP manipulation, DNS spoofing, IPv6 attacks, and IDS/IPS evasion.
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.
