Fine to try. Some of what it can do is expected: a media skill usually calls an AI service over the internet.

Proof that a change works. Picks cheapest sufficient proof (test, screenshot, video, before/after). Use when dev asks for proof, evidence, "video", "przed i po", "dowod", "pokaz ze dziala", or when worker must show proof of a change.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'evidence' ] || [ -L ~/.agents/skills/'evidence' ]; then echo 'A skill folder named evidence 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 "$d" checkout --quiet 'c5dcf1af0899bee2156329530706ebc787c99f4f' -- '.nitpick/skills/evidence' && mkdir -p ~/.agents/skills && cp -R "$d"/'.nitpick/skills/evidence' ~/.agents/skills/'evidence' && 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/'evidence' ~/.claude/skills/'evidence' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
