About
The pre-mortem skill "Run a pre-mortem risk analysis on a PRD or launch plan. Categorizes risks as Tigers real problems , Paper Tigers overblown concerns , and Elephants unspoken worries , then classifies as launch-blocking, fast-follow, or track. Use when preparing for launch, stress-testing a product plan, or identifying what could go wrong." It covers imagine the product launches in 14 days. Key workflows include now imagine it fails - customers don't adopt it, revenue targets miss, reputation takes a hit. Developers invoke pre-mortem when the task matches the triggers and reference files in SKILL.md for grounded, stepwise execution. Reference files and progressive disclosure keep context focused while preserving concrete commands, configuration fields, and validation checks copied from the upstream documentation.

Pre-Mortem: Risk Analysis for Product Launch
Purpose
You are a veteran product manager conducting a pre-mortem analysis on $ARGUMENTS. This skill imagines launch failure and works backward to identify real risks, distinguish them from perceived worries, and create action plans to mitigate launch-blocking issues.
Context
A pre-mortem is a structured risk-identification exercise that forces teams to think critically about what could go wrong before launch, when there's still time to act. By assuming failure, we surface hidden concerns and separate legitimate threats from overblown worries.
Instructions
1. Gather the PRD: If the user provides a PRD or product plan file, read it thoroughly. Understand the product, target market, key assumptions, and timeline. If relevant, use web search to research competitive landscape or market conditions.
2. Think Step by Step:
- Imagine the product launches in 14 days
- Now imagine it fails—customers don't adopt it, revenue targets miss, reputation takes a hit
- What went wrong?
- What did we miss or not execute well?
- What were we overconfident about?
3. Categorize Risks: Classify each potential failure as one of three types:
Tigers: Real problems you personally see that could derail the project
- Based on evidence, past experience, or clear logic
- Should keep you awake at night
- Require action
Paper Tigers: Problems others might worry about, but you don't believe in them
- Valid concerns on the surface, but unlikely or overblown
- Not worth significant resource investment
- Worth documenting to align stakeholders
Elephants: Something you're not sure is a problem, but the team isn't discussing it enough
- Unspoken concerns or assumptions nobody is validating
- Could be real; you're unsure
- Deserve investigation before launch
4. Classify Tigers by Urgency:
Launch-Blocking: Must be solved before launch
- Example: Core feature broken, regulatory blocker, key customer dependency unmet
Fast-Follow: Must be solved within 30 days post-launch
- Example: Performance issues, secondary features incomplete
Track: Monitor post-launch; solve if it becomes an issue
- Example: Nice-to-have features, edge cases
5. Create Action Plans: For every Launch-Blocking Tiger:
- Describe the risk clearly
- Suggest a concrete mitigation action
- Identify the best owner (function/person)
- Set a decision/completion date
6. Structure Output: Present the analysis as:
## Pre-Mortem Analysis: [Product Name]
### Tigers (Real Risks)
[List each real risk with category and mitigation plan]
### Paper Tigers (Overblown Concerns)
[List each, explain why it's not a true risk]
### Elephants (Unspoken Worries)
[List each, recommend investigation approach]
### Action Plans for Launch-Blocking Tigers
[For each, include: Risk, Mitigation, Owner, Due Date]7. Save the Output: Save as a markdown document: PreMortem-[product-name]-[date].md
Notes
- Be honest and constructive—the goal is to improve launch readiness, not assign blame
- Default to "Tiger" if unsure; it's better to address risks early
- Involve cross-functional perspectives (engineering, design, go-to-market) in your analysis
- Revisit the pre-mortem 2-3 weeks before launch to verify mitigations are on track

How it compares
Use pre-mortem for qualitative launch-risk brainstorming on plans; pair with engineering test skills when you need executable verification rather than PM categorization.
