SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

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.

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.
