Amazon Revised Its Rules for
AI-Based Tools.
Problems with AI
Amazon has long used its own programming assistant based on artificial intelligence, Kiro (kiro.dev). However, in late 2025 and early 2026, due to an incident that Amazon described as a 'user error', a series of service outages occurred. As a result, there was a 13-hour interruption in service operations, on March 2, 2026, around 120,000 orders were lost and 1.6 million website errors were triggered. Three days later, on March 5, the outage caused a 99% drop in orders across Amazon's North American marketplaces, which led to 6.3 million lost orders in a single day. More details about the outages can be found here.
New Rules
The company is currently applying a structured 90-day security recovery program to around 335 mission-critical systems in its retail infrastructure. The new workflow for engineers generally includes the following steps:
- 1. Mandatory expert review: any code changes, whether generated by artificial intelligence or not, made to a mission-critical system, must be reviewed by at least two engineers before deployment.
- 2. Senior engineer approval: junior developers using AI tools must receive approval from a senior engineer.
- 3. Formal documentation: teams must use internal tools to create a structured document describing the AI's actions and the methods used to test it before production release.
- 4. Audit logs: directors and vice presidents now need to monitor production code activity so no one bypasses these safety measures just to meet deadlines.
Takeaway
Even major players like Amazon can become too confident that AI is a cure-all and give it too much authority.
