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

Application-layer denial-of-service testing — ReDoS, decompression bombs (gzip request bodies), server processing delays, GraphQL amplification cross-reference, and stack trace exploitation for DoS intelligence. Use when probing for resource exhaustion, regex-heavy input validation, compressed request handling, or slow-processing endpoints.

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/'app-layer-dos' ] || [ -L ~/.agents/skills/'app-layer-dos' ]; then echo 'A skill folder named app-layer-dos 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 "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/app-layer-dos' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/app-layer-dos' ~/.agents/skills/'app-layer-dos' && 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/'app-layer-dos' ~/.claude/skills/'app-layer-dos' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
