nextjs-cache-poisoning

90 / 100 · Low risk

Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By dreadnode/capabilities (GitHub) · security · 22 stars · scanned at commit 3ceeb34

Internal cache poisoning in Next.js via stale cache entries and header manipulation. Use when target runs Next.js (/_next/ paths, x-nextjs-cache header, __nextjs_original-cache-control) and you need to poison cached responses.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'nextjs-cache-poisoning' ] || [ -L ~/.agents/skills/'nextjs-cache-poisoning' ]; then echo 'A skill folder named nextjs-cache-poisoning already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/dreadnode/capabilities' "$d" && git -C "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/nextjs-cache-poisoning' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/nextjs-cache-poisoning' ~/.agents/skills/'nextjs-cache-poisoning' && 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/'nextjs-cache-poisoning' ~/.claude/skills/'nextjs-cache-poisoning' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
