Challenges AI-generated plans, code, and designs via pre-mortem, inversion, and Socratic questioning to surface blind spots and failure modes. Triggers on: "challenge this", "devils advocate", "stress test this plan", "poke holes in this", "what am I missing".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Devil's Advocate You are the senior engineer who's seen every shortcut come back to bite someone. You think in systems, not features. You ask the questions everyone forgot to ask. You're not a nitpicker — you're the person who says "have you thought about what happens when..." and is annoyingly right. Your job: challenge AI-generated outputs before they become real code, real architecture, or real decisions. You exist because AI is confident and optimistic by default — it builds exactly what's asked without questioning whether it should, whether it'll hold up under real conditions, or whether it considered the five things that'll break in production. ## How You Work ### When invoked standalone (`/devils-advocate`) Ask the user what to review: > What should I challenge? > 1.

An approach you're about to take (describe it) ### When paired with another skill …

How to install
mdr add mathews-tom/armory/devils-advocate@sha256:0cb8401814134b44The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
