vals.ai > benchmarks > terminal-bench-4

Terminal-Bench 4.0

1+ hour, 30+ min ago   (269+ words) Where Terminal-Bench 2.x was mostly software engineering and system administration, 4.0 is deliberately wide. The tasks span seven categories: We include Terminal-Bench because it is widely reported by model providers, because it reflects the kind of end-to-end terminal work that agentic…...

I audited my own ML linter and had to withdraw its best evidence

1+ hour ago   (705+ words) I maintain trainproof, a deterministic linter for ML training runs. No model scores your run — every verdict is a rule that either fires or doesn't, and every finding prints the numbers behind it. Before releasing 0.22.0 I put it through two…...

Why AI coding assistants write clean-looking CSS that breaks in production (and how to fix it)

52+ min ago   (636+ words) If you use Cursor, Claude, or Copilot for frontend work, you already know the feeling. You prompt the model to generate a dashboard card or a modal component. It spits out fifty lines of clean TypeScript and Tailwind classes in…...

Day 47: Copy Requirements Before the Code, and SQS Has No Priority Feature

57+ min ago   (641+ words) Neither of today's tasks has a setting for the thing it delivers. Docker has no switch that makes rebuilds fast, and SQS has no switch that makes a queue high priority. In both cases, the feature is the order you…...

Mock Server na prática: entendendo JSON Server e o db.json

2+ hour, 22+ min ago   (1662+ words) Um guia para iniciantes entenderem o que é um Mock Server, como o JSON Server funciona e como utilizar um db.json para desenvolver e testar aplicações frontend. Quando estamos desenvolvendo uma aplicação frontend, existe um problema muito comum: a…...

Afriex Integrations: Sandbox, Idempotency, and Webhook Simulation

2+ hour, 7+ min ago   (723+ words) Most payment integration bugs never show up in a manual test. You click through the happy path once, it works, you ship it. Then in production a network blip causes a retry, two webhook deliveries arrive out of order, or…...

Keep the Score Contract Out of the Agent's Write Set

3+ hour, 34+ min ago   (803+ words) A green CI job on an agent branch is not a score. It is a claim that the tree the agent left behind still exits zero. Those claims diverge as soon as the agent can delete tests, rewrite goldens, skip…...

Preventing Duplicate Agent Execution on iOS

4+ hour, 58+ min ago   (374+ words) Stable operation IDs prevent iOS retries from duplicating agent tools across LangGraph, MCP Tasks, Kafka, and App Attest. The dangerous state is therefore not “request failed,” but “completion is unknown.” If that request starts an agent that charges an account,…...

The agent refused to delete our "dead" backend. It was right.

4+ hour, 25+ min ago   (968+ words) A few weeks ago I asked an AI agent to delete a directory from a live production repository. The ticket described it as a dead legacy backend. The HTTP service it contained had been retired, the product ran on a…...
