Five problems. Five wins.
Bigger codebases. Tighter deadlines. Same model bill at the end of the month. Here's what changed when each of these five plugged Tetris in.
Maya, 2 AM. Charges going through twice.
Solo Stripe-checkout startup. Three angry customers in the inbox. The bug is somewhere in 300+ files of webhook code, but Maya only needs to read a handful to find it.
Tetris kept the webhook route, the billing model, and the migration in the agent's view — and pruned everything else. Bug found in one round-trip.
Devraj has 47 things to recreate. Which are safe?
A nightly drift report gives him a wall of red. He needs the agent to tell him — for each line — if it's a cosmetic version bump or a thing that wipes a database.
Tetris read only the modules touched by the drift, ignored the other 920 files. Plan-review went from 6 minutes to under 90 seconds.
Aida cleared 30 PRs before lunch.
Saturday morning, queue at 30. Without compression, her library's own type definitions eat the prompt before the model gets to the diff.
Tetris dropped repeated boilerplate in the prompt and kept the diff intact. The agent finally had room to think about the change.
Tomás found the bottleneck on the first try.
His attention kernel was 3× slower than the reference. The file is 5,400 lines of templated GPU code. The agent only needed the reduction primitive and the profile output.
Tetris collapsed the templated dispatch tables and stripped repeated build noise. The agent saw a tight, focused diff — the access pattern jumped out immediately.
Lin migrated 12 services in a single sprint.
JWT to session tokens, both running side-by-side during rollout. The agent had to understand the auth contract without re-reading a thousand HTTP handlers.
Tetris kept the middleware path and the integration tests; everything else fell away. Lin's plan went green in 4 rounds instead of 9.
