Same AI tool. Same codebase access. Same staging incident. Three experienced engineers spent hours and couldn't find the root cause. I found it in about 20 minutes — and I barely knew what half the tools did. This isn't a story about juniors being better than seniors. It's about a mental model for AI collaboration that anyone can use — and why the "obvious" way most people use AI actually holds them back. The Incident A message hits the team Slack channel: "Staging is broken. We're investigating." The error: alembic current ERROR: Can't locate revision identified by 'ba29cdc8739d' FAILED: Can't locate revision identified by 'ba29cdc8739d' For context: Alembic is a database migration tool for Python. Every migration has a unique revision ID. The staging database thought it was on a revision that didn't exist in the codebase. Someone had run a migration from code that was never merged. How the Investigation Went — The Usual Way Three experienced engineers jumped on it. They had full acce
