What problem does it solve?

Validate a plan or spec before implementation using a multi-model council to obtain early, well-reasoned judgments.

Core Features & Use Cases

  • Multi-model council validation: Run plan/spec reviews with multiple AI agents to surface risks and feasibility gaps.
  • Structured verdicts: Produce clear PASS/WARN/FAIL verdicts with reasoned findings.
  • Lifecycle integration: Connects to plan docs, generates a pre-mortem report, and guides next steps.
  • Use Case: A product team uses /pre-mortem to validate a new feature plan before committing engineers or timelines.

Quick Start

  • /pre-mortem
  • /pre-mortem path/to/PLAN.md
  • /pre-mortem --quick path/to/PLAN.md
  • /pre-mortem --deep path/to/SPEC.md
  • /pre-mortem --debate
  • /pre-mortem --preset=architecture path/to/PLAN.md

FAQPage Schema
What is a pre-mortem plan validation and when do I need one?

Pre-mortem plan validation is a risk assessment technique that reviews a project plan or spec before implementation. You need it to surface feasibility gaps and risks early, before committing engineers or timelines to a new feature.

How do I validate a plan before implementation?

To validate a plan before implementation, run a multi-model council review against your plan document. Use the /pre-mortem command with a file path to generate structured PASS/WARN/FAIL verdicts with reasoned findings.

Can I run a risk assessment on a SPEC.md file?

Yes, you can run a risk assessment on a SPEC.md file. Use the /pre-mortem --deep path/to/SPEC.md command to perform a thorough feasibility review of your specification document before development begins.

What's the best way to review an architecture plan for risks?

The best way to review an architecture plan for risks is using /pre-mortem --preset=architecture path/to/PLAN.md. This applies a specialized council preset to surface architecture-specific feasibility gaps and produce actionable guidance.

Does the pre-mortem council support quick validation for fast iterations?

Yes, the pre-mortem council supports quick validation. Use the /pre-mortem --quick path/to/PLAN.md command to obtain a fast, structured verdict with reasoned findings when you need rapid plan validation across workstreams.

Can I trigger a debate mode during plan validation?

Yes, you can trigger debate mode during plan validation by using the /pre-mortem --debate command. This engages the multi-model council in a deeper reasoning process to produce more thoroughly examined risk assessment findings.
