AI Subagents orchestration are now reliable
Since the end of 2025, I've been thinking a lot about how to improve my development workflow with AI agents. Like many developers, I started using agents in their simplest form: manually. One agent, one task, a lot of supervision, and a lot of interaction to keep the work moving in the right direction. As I became more comfortable with these tools, understanding how to communicate with them, how…
As of 2025, AI subagents have become reliable enough for developers to delegate tasks to them in a development workflow. Initially, coordinating subagents proved challenging, with the parent agent sometimes directing them to unrelated work or repeatedly seeking results. These issues stemmed from limitations in the agent harness and model behavior, leading to duplicated efforts and unpredictable behavior.
However, recent developments have made Codex subagent orchestration reliable enough for developers to design development processes around it. This newfound reliability allows developers to think about task delegation, parallel execution, task dependencies, context requirements, and integration strategies. Before delegating tasks, developers must break down features into well-scoped tasks with clear boundaries, outputs, constraints, and dependencies.
Planning is crucial, as the number of agents is less important than whether the work has been correctly decomposed. Repository-level context, such as good AGENTS.md instructions, architecture documentation, reusable skills, tests, and strict type requirements, significantly enhances the performance of AI agents. By reducing the cost of certain engineering tasks previously requiring significant developer time, AI subagents change the economics of quality.
They enable agents to investigate edge cases, expand tests, review changes, and inspect unfamiliar code parts, all while minimizing the need for human intervention. While AI does not guarantee quality, it makes it feasible to achieve a higher level of quality in software development.
