Sponsor this spotMaurice Heumann and a few volunteers ran up to 16 Claude Code and Codex agents for three months to rebuild an old first-person shooter as readable, compilable C++. Agents used a disassemb…
To keep code aligned with what was actually asked for, a developer periodically has an agent re-read every user message in the project and write a fresh statement of intent, then checks t…
A payment job ran twice after a worker died before it acknowledged the message, and 37 customers were charged two times. The engineer then spent two weeks checking all 140 Celery jobs in…
A Claude Code user keeps tasks in a YAML todo file managed by a small Python script, and added a task-manager sub-agent with just two actions: fetch the next task and mark a task complete…
One developer spent 15 days running two coding agents side by side on one project. Claude Code handled the frontend and Codex handled the backend. Both worked in a shared space called Tut…
