black-box-tester

100 / 100 · Low risk

Fine to try.

By polubis/gon-stack (GitHub) · other · 41 stars · scanned at commit c5dcf1a

Build tests from user test plan using strict black-box behavior. Trigger when user asks to generate tests from requirements/spec and avoid implementation leaks. Report untestable requirements with reason, then map each requirement to test status table.

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/'black-box-tester' ] || [ -L ~/.agents/skills/'black-box-tester' ]; then echo 'A skill folder named black-box-tester already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polubis/gon-stack' "$d" && git -C "$d" checkout --quiet 'c5dcf1af0899bee2156329530706ebc787c99f4f' -- '.nitpick/skills/black-box-tester' && mkdir -p ~/.agents/skills && cp -R "$d"/'.nitpick/skills/black-box-tester' ~/.agents/skills/'black-box-tester' && 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/'black-box-tester' ~/.claude/skills/'black-box-tester' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
