Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Scan a source tree for weak cryptographic primitives: MD5 / SHA-1 used for security purposes, DES / 3DES / RC4 ciphers, ECB block mode, custom-built crypto (XOR loops, hand-rolled HMAC), hardcoded IVs, predictable random (Math.random / java.util.Random for crypto seeds), missing certificate verification (verify=False, rejectUnauthorized: false). Use when: pre-merge gate on crypto-touching code, audit before SOC2 / PCI assessment, post-incident review when "we found a weakness in our token signi…

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'detecting-weak-cryptography' ] || [ -L ~/.agents/skills/'detecting-weak-cryptography' ]; then echo 'A skill folder named detecting-weak-cryptography already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jeremylongshore/tons-of-skills-marketplace' "$d" && git -C "$d" checkout --quiet '8dc06f02eb00b7d8d1c0e69dfb3add2fd9500979' -- 'skills/.curated/detecting-weak-cryptography' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/.curated/detecting-weak-cryptography' ~/.agents/skills/'detecting-weak-cryptography' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'detecting-weak-cryptography' ~/.claude/skills/'detecting-weak-cryptography' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
