Use when a handler turns user input into a filesystem path, including archive extraction. Traces the path from request to open, tests ../ and encoded traversal, and confines reads to a base directory.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'review-path-traversal-in-file-apis' ] || [ -L ~/.agents/skills/'review-path-traversal-in-file-apis' ]; then echo 'A skill folder named review-path-traversal-in-file-apis already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jiayaoqijia/cryptoskill' "$d" && git -C "$d" checkout --quiet '0dc9f60ab1f3fcae24da49c4cef09c46c589f903' -- 'skills/payments/0xklen-review-path-traversal-in-file-apis' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/payments/0xklen-review-path-traversal-in-file-apis' ~/.agents/skills/'review-path-traversal-in-file-apis' && 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/'review-path-traversal-in-file-apis' ~/.claude/skills/'review-path-traversal-in-file-apis' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
