Why it matters
This article highlights an effective way to leverage AI tools for debugging complex software issues, which can be valuable for engineering teams.
Key Points
- 1Three experienced engineers spent hours trying to debug a staging issue, but couldn't find the root cause
- 2A junior engineer with less experience was able to solve the issue in 20 minutes by taking a different approach
- 3The key was asking the AI tool (Claude) to look for clues in the database itself, rather than just checking logs and history
- 4This led to discovering the exact timestamp of when the problematic migration was run, which provided the crucial insight

The article describes a scenario where a staging environment was broken due to a database migration issue. Three experienced engineers, all using the AI tool Claude, spent hours investigating the problem but couldn't determine the root cause. A junior engineer with less experience was able to solve the issue in 20 minutes by taking a different approach. Instead of focusing on checking logs and history, the junior engineer asked Claude to look for clues in the database itself. This led to the discovery that the problematic migration had used the `NOW()` function to set the `created_at` timestamp, which provided the crucial insight about when the migration was actually run. The article emphasizes that the
