What It Does
Thinking Pre Mortem packages a focused coding & development workflow for an AI agent. Before committing to a plan or launch, assume it already failed and reason backward through concrete causes — convert failure paths into mitigations, gates, and stop checks. It is best suited to users who can review the resulting actions and provide only the accounts, files, or command access needed for the task. It is not a substitute for human approval on destructive, financial, security-sensitive, or public-facing actions.
Popular Use Cases
- Review and improve a code change
- Automate a repeatable development task
- Investigate failures and prepare a fix
