Ctf Similar Search skill
ctf-similar-searchljagiello/ctf-skillsctf-similar-search/SKILL.md
Searches for similar CTF challenge writeups using Tavily API for search and content extraction. Use when the user requests finding related challenges, when solve-challenge has failed multiple times and needs reference solutions, or when first identifying a challenge type and seeking examples.

Install the Ctf Similar Search skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/ljagiello/ctf-skills --skill ctf-similar-search
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/ljagiello/ctf-skills.git /tmp/ctf-skills mkdir -p ~/.claude/skills cp -R /tmp/ctf-skills/ctf-similar-search ~/.claude/skills/ctf-similar-search
For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.
What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 58 tok |
| When the agent uses it | The SKILL.md instructions | 1,429 tok |
| Only if opened | 2 bundled files (7 KB) | varies |
Until it is used, ctf-similar-search costs about 24× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 12 skills from ljagiello/ctf-skills would load 1,099 tokens of descriptions. Skills vs MCP study
Checks

3.5k88 tok idle · 9,386 in use - ctf-malwareljagiello/ctf-skills
Provides malware analysis and network traffic techniques for CTF challenges. Use when analyzing obfuscated scripts, malicious packages, custom crypto protocols, C2 traffic, PE/.NET binaries, RC4/AES encrypted communications, YARA rules, shellcode analysis, memory forensics for malware (Volatility malfind, process injection detection), anti-analysis techniques (VM/sandbox detection, timing evasion, API hashing, process injection, environment checks), or extracting malware configurations and indicators of compromise.
3.5k101 tok idle · 2,213 in use - ctf-miscljagiello/ctf-skills
Provides miscellaneous CTF challenge techniques for problems that do not cleanly fit the main categories. Use for encoding puzzles, pyjails, bash jails, RF/SDR, DNS oddities, unicode tricks, esoteric languages, QR or audio puzzles, constraint solving, game theory, unusual sandbox escapes, and hybrid logic puzzles. Prefer a more specific skill first when the challenge is mainly web, pwn, reverse, forensics, malware, OSINT, or crypto. Treat this as the fallback skill for genuine cross-category or edge-case challenges, not the default starting point.
3.5k122 tok idle · 7,542 in use - ctf-osintljagiello/ctf-skills
Provides open source intelligence techniques for CTF challenges. Use when gathering information from public sources, social media, geolocation, DNS records, username enumeration, reverse image search, Google dorking, Wayback Machine, Tor relays, FEC filings, or identifying unknown data like hashes and coordinates.
3.5k65 tok idle · 2,414 in use - ctf-pwnljagiello/ctf-skills
Provides binary exploitation techniques for CTF challenges. Use when you already have a vulnerable native target or service and need to turn memory corruption or low-level primitives into code execution or privilege escalation, such as buffer overflows, format strings, heap bugs, ROP, ret2libc, shellcode, kernel exploitation, seccomp bypass, sandbox escape, or Windows/Linux exploit chains. Do not use it when the main blocker is understanding what the binary does; use reverse engineering first. Do not use it for pure web bugs, disk or packet forensics, or standalone crypto/math challenges.
3.5k5122 tok idle · 5,113 in use - ctf-reverseljagiello/ctf-skills
Provides reverse engineering techniques for CTF challenges. Use when the main job is to understand how a compiled, obfuscated, packed, or virtualized target works before exploiting or solving it, including binaries, APKs, WASM, firmware, custom VMs, bytecode, game clients, malware-like loaders, and anti-debug or anti-analysis logic. Do not use it when the vulnerability is already understood and the remaining task is exploitation; use pwn instead. Do not use it for pure web workflows, log or disk forensics, or standalone crypto problems unless reversing the implementation is the real blocker.
