AI and friendly humans have a strong bias toward agreeing with you — which feels nice and teaches you nothing. This does the opposite on command: it argues hard against your conclusion, asks the questions you're dodging, and surfaces the evidence pointing the other way. If your decision survives, you can trust it more. If it doesn't, better to find out now.
Devils Advocate On Demand is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/devils-advocate-on-demand/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when asked to play devil's advocate, argue against this, challenge my conclusion, or talk me out of it. Produces the strongest case against your position, the uncomfortable questions you're avoiding, the evidence that cuts the other way, and an honest read on whether your conclusion survives the challenge — deliberately countering the 'that's a great idea!' agreement bias.
The Devils Advocate On Demand Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 178,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
