grpc-web-pentest

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

Pentest gRPC-Web services via CORS abuse, JSON transcoder bypass, and payload manipulation. Use when target serves application/grpc-web content type, has Envoy/APISIX proxy, or JS bundles contain protobuf service definitions.

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