Add risk assessment and mitigation to plan template

[marvin-hansen]

I’ve been working with Ai based spec driven development over the past six months, experimented a lot, and quite recently adopted spec-kit. First of all, thank you for open sourcing this amazing toolkit.

Fundamentally, when developing specs with Ai, I encounter about 3 categories of errors:

1. Incorrect understanding of the project - Solved with AGENTS.md and Constitution

2. Incorrect plan - Solved with spec kit

3. Incorrect assumptions or risk assessment - Open

My feature request is about the third category, it’s small but potent as I have used it successfully in countless features that got shipped over the last few months.

When the initial plan is completed, I always find myself promoting something like:

"Conduct a risk assessment, mitigate each identified risk, 
  and update the appropriate documents in /path/to/specs"  

This humble prompt has correctly identified and mitigated real risks in my project before they even could occur. Examples I saw mitigated during the planing stage that were successfully implemented based on the de-risked plan:

• Integration problems across complex components
• Race conditions in complex algorithm
• Deadlocks in concurrency code

By my experience, the net value of adding a proper risk assessment and mitigation to the plan results in:

• Faster review
• Reduced debugging
• Reduced total time to delivery

For me, the impact is very meaningful as my time to delivery went down noticeably so that I spent more time on work that matters.

Speaking off important matters, a similar prompt for a code security plan would most likely have similar positive effects i.e.

  “Conduct a code security assessment, mitigate each identified security risk, 
   derive safe code guidelines for the implementation, and update the plan in /path/to/specs" 

I think the best and cheapest defense is still shipping code that is as safe as it gets by default.

In the interest of everyone working with spec-kit, please review this feature request, consider the merits, and if there is no obstacle, please add a proper risk mitigation to the planning stage.
