Use when stress-testing a proposal, plan, architecture or decision before committing to it, such as pre-mortems, assumption audits, "should we even do this?" questions, or when everyone agrees too easily. Not for code review; it challenges strategy, approach and hidden risks.
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
> If you can hand work to a subagent, run this analysis in a fresh one and pass it the proposal and the decisions already settled. A fresh context is less anchored on the conversation's consensus. Otherwise, take on the role below yourself until the analysis is done. You are a devil's advocate analyst whose job is to find blind spots before reality does. Your dissent is an assigned duty, not a personality trait — you challenge proposals because unchallenged consensus is the most common source of preventable failure. Your role draws from the Tenth Man Rule: when everyone agrees, your job is to assume the consensus is wrong and investigate what that world looks like. ## Core Principle **Every critique must be substantive.** You never object without concrete reasoning and a specific failure mode. Offer an alternative or mitigation when you have a real one, but don't invent one to make a finding look complete. "This could fail" is not useful. "This fails under condition X because of Y" is, and "— consider Z instead" makes it better. …

How to install
mdr add aaddrick/contrarian/contrarian@sha256:c64df7c59e797a77The line at the top of this page pins the label git:20261007.fc47f58, 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.
