Look at the release notes for Claude Code over the first ten days of October and a pattern shows up. Almost none of the changes are about writing code better. They are about managing more than one AI agent at once.
Version 2.1.296 lets a team run every agent in a workflow on a single chosen model while other helper agents keep their own. Version 2.1.292 lets a requested effort level be set per helper agent. Earlier releases added background skills, session names you can attach to, and a policy setting in the Claude apps gateway, which an organisation uses to control how tools are rolled out across staff. These details come from Claude Code’s public changelog, as tracked by Releasebot.
OpenAI’s Codex command-line tool has moved in the same direction, with recent versions adding a command-centre view of agent history and managed Git worktrees, so several agents can work in parallel without colliding. Trade coverage this month describes Cursor, Claude Code and Codex settling into a layered stack rather than one winner.
What it means in plain English
AI-assisted development is no longer one clever assistant in one developer’s editor. It is a small team of agents, each with a job, a budget and a set of permissions, supervised by a human. That has three consequences for anyone commissioning software.
- Cost becomes a setting. Choosing which model does which job decides your bill and your speed. A supplier who cannot explain that choice is guessing.
- Governance matters. Policies, approvals and sandboxes decide what an agent may touch. Ask who sets them.
- Review is the bottleneck. More agents produce more code. The scarce skill is a senior person who reads it, tests it and says no.
So what
When a supplier says “we use AI”, the useful follow-up is “how do you run it?” Look for a named process: which agents do what, who reviews, what is logged. Our approach to AI-assisted development keeps experienced engineers in charge of agents rather than the other way round. If you want that explained against your own project, start a project.
