The new Codex app is designed as an "agent command center" for managing multiple AI agents working in parallel. This interface-driven approach suggests OpenAI believes the developer's role is evolving from a hands-on coder into a high-level orchestrator, fundamentally changing the software development paradigm.

Anthropic's new "Agent Teams" feature moves beyond the single-agent paradigm by enabling users to deploy multiple AIs that work in parallel, share findings, and challenge each other. This represents a new way of working with AI, focusing on the orchestration and coordination of AI teams rather than just prompting a single model.

An advanced workflow is emerging in OpenAI's Codex: the 'monothread.' Instead of fragmented chats, users maintain one continuous conversation. This leverages context compaction to build a long-term, evolving understanding of the user's projects, turning the AI into a persistent strategic partner for iterating on complex questions rather than a tool for one-off tasks.

Unlike standard AI chats which are isolated, Cowork's "Projects" feature allows you to chain multiple tasks together. All tasks within a project share the same context and memory, allowing the AI to build on previous work and understand the larger goal.

Instead of starting new chats for every task, use single, long-running 'monothreads' for each major workstream. Advanced context compaction in tools like Codex allows these threads to persist memory over time, turning the AI from a simple Q&A bot into an ongoing project collaborator with deep context.

The new Codex app encourages a 'monothread' pattern where a single AI conversation is kept alive for weeks. Improved context compaction allows the thread's value to increase over time, moving beyond the old model of starting fresh for each task and creating a persistent, learning assistant.

The most advanced use of AI agents involves breaking the 'prompt-wait-review' cycle. Features like Codex's 'steer' and side panel allow users to inspect, annotate, and redirect the AI while it's working. This shifts the paradigm from sequential turns to a continuous, parallel collaboration.

Most AI tools are single-player experiences. Linear is designing its agent sessions to be shared, collaborative spaces. Multiple people, like a PM and a designer, can jump into the same chat with an agent, see its work, and give it feedback together, collapsing the collaboration loop.

After a productive, iterative conversation with Codex that achieves a desired outcome, you can ask it to analyze that same thread and create a reusable 'skill'. This templatizes the successful workflow, making it easy to replicate consistently.
