The Pre-Mortem Analyst
Starts from "this flopped" and works back to why.
What does The Pre-Mortem Analyst do?
The Pre-Mortem Analyst is the Assume-it-failed investigator lens on a Decidi council — one of 86 expert personas convened to review and challenge important work. It scrutinises potential failure modes and root causes, early warning signals of failure, assumptions most vulnerable to breaking. It never debates alone: it’s one independent voice among multiple frontier AI models that argue across rounds, with an impartial moderator and a proprietary Final QA audit before the verdict.
You are The Pre-Mortem Analyst. You imagine it is a year from now and the plan has failed badly, then you write the post-mortem in advance and trace the most likely causes. This inversion surfaces risks that forward-looking optimism hides. List the two or three failure modes most likely to actually kill this, and what early signal would warn us. Engage other agents by showing which of their assumptions is the one that breaks first. Be concise and specific about mechanisms, not generic worries. Your blind-spot: vivid failure stories can over-weight dramatic risks over boring fatal ones, so rank by likelihood, not drama.

“What are the top three failure modes?”
“Which assumption is most likely to break first?”
“What early signals indicate potential failure?”
No single lens is complete. Vivid failure stories can over-weight dramatic risks over boring fatal ones, so rank by likelihood, not drama. On a Decidi council that bias is deliberately checked — other personas argue the opposite case, and the Final QA audit catches what one viewpoint would wave through.
On Decidi, The Pre-Mortem Analyst never debates alone. It is one independent voice in a council of multiple frontier AI models — GPT, Claude, Gemini and Grok — that challenge each other across rounds. Its job is to surface what a single AI would miss; an impartial moderator then weighs the dissent, a Final QA audit checks the result for hallucinations, and you get one decisive verdict.
Questions
When should you bring in The Pre-Mortem Analyst?
When evaluating a strategic plan's resilience against failure. The Pre-Mortem Analyst scrutinises potential failure modes and root causes, early warning signals of failure, assumptions most vulnerable to breaking — the angle a single general-purpose AI answer tends to skip. On Decidi you seat it alongside other expert personas so the review is rounded, not one-sided.
Does The Pre-Mortem Analyst make the call on its own?
No. The Pre-Mortem Analyst is one independent voice in a council of multiple AI models. An impartial moderator weighs its argument against the others, and an always-on Final QA audit reviews the verdict for hallucinations and weak reasoning before you act on it.
Which AI model runs The Pre-Mortem Analyst?
The Pre-Mortem Analyst runs on a frontier model, and a council assigns its members across OpenAI GPT, Anthropic Claude, Google Gemini and xAI Grok — so a multi-member debate genuinely spans different models rather than one model role-playing several.
