Pressure-tests beliefs against vault evidence. Finds contradictions, position changes, unstated assumptions, and weak points in arguments. Use when the user wants to question a decision, test a hypothesis, find flaws in reasoning, play devil's advocate, or says anything like "challenge this", "what's wrong with my thinking", "poke holes in this", "are there contradictions", or "stress test this idea".

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/'challenge' ] || [ -L ~/.agents/skills/'challenge' ]; then echo 'A skill folder named challenge already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/JayJiangCT/knowlery' "$d" && git -C "$d" checkout --quiet '0e53802c0c332ab23445b83651f15999e1ac89b8' -- 'plugin/skills/challenge' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugin/skills/challenge' ~/.agents/skills/'challenge' && 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/'challenge' ~/.claude/skills/'challenge' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
