h2-waf-bypass
90 / 100 · Low risk
Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

Bypass WAF body/path inspection via HTTP/2 binary framing — delayed DATA frames blind out-of-process WAFs, body size truncation evades ext_authz limits, Extended CONNECT converts methods past ACLs. Includes black-box proxy+WAF fingerprinting. Use when WAF blocks payloads over HTTP/1.1 but target supports HTTP/2, or when standard 403-bypass and parser-differential techniques fail.
Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'h2-waf-bypass' ] || [ -L ~/.agents/skills/'h2-waf-bypass' ]; then echo 'A skill folder named h2-waf-bypass 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 "$d" checkout --quiet '3ceeb34c0c33dc36738cf0d4ec86e38b53d98216' -- 'capabilities/web-security/skills/h2-waf-bypass' && mkdir -p ~/.agents/skills && cp -R "$d"/'capabilities/web-security/skills/h2-waf-bypass' ~/.agents/skills/'h2-waf-bypass' && 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/'h2-waf-bypass' ~/.claude/skills/'h2-waf-bypass' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
