What is a pre-mortem in software development?

A pre-mortem is a strategy where a team imagines a project has already failed, then works backward to determine what led to that failure to prevent it in reality.

Can I integrate this with other developer workflows?

Yes, this skill is designed to feed guardrails into code review processes and pass immediate tasks directly to your project planning tools.

What is the recommended timeframe for a pre-mortem?

While it supports 30 and 180-day horizons, the default 90-day window is recommended for most mid-sized software initiatives.

How does the /ctx:pre-mortem command assist the process?

It structures the brainstorming session by prompting for horizons and success states, then automatically categorizes risks across technical and organizational dimensions.

Does it only cover technical bugs?

No, the skill evaluates failure modes across tech, UX, market competition, organizational hurdles, and compliance constraints.

コラボレーションツール

Facilitates proactive risk assessment by imagining project failures to establish robust guardrails and feature mitigations.

The Pre-Mortem skill helps teams anticipate potential project pitfalls before they occur, allowing for the proactive creation of mitigations and feature improvements. By defining a success state and then identifying failure modes across technical, user experience, and organizational domains, it transforms abstract risks into actionable tasks. This skill is essential for planning complex initiatives where early detection of compliance constraints or technical debt can save significant rework and ensure long-term project stability.
