Couldn't be more excited to share my recent focus: .Codex, a software engineering agent that answers codebase questions and drafts pull requests—working on its own computer. This video from @DKundel sums it up nicely. This is just the beginning. Excited to hear what you think!.

This is cool: @.yaroslavyaroslav on GitHub built a Sublime Text plugin around the Codex CLI. Supports code editing, sandboxed commands, and MCP

Factory 🤝 Agents.
@FactoryAI natively supports and it's exciting the industry is standardizing best practices for agent-driven development.

This was a useful & interesting read. Anyone else have setups they'd want to share?.
@embirico @OpenAI @sqs @simpsoka Took way to long to get it in a gist. It's basically a wiki of how to code in various parts of the app. I think have different short specific files for codex, gemini, vs code, cursor, etc, which direct the agent to read the

Codex 🤝 Amp. Hats off to @sqs for starting this conversation and being so collaborative. We need more of this in the industry.

One of my favorite parts of working with @hansonwng and the Codex research team:.Instead of focusing on pure intelligence towards writing functional code, we also pushed on the softer aspects that make code mergable.
The hardest part of building @openai's Codex-1 model wasn't making it the smartest — it was giving it taste. @hansonwng and @embirico dig into what it takes to go beyond crushing coding contests to writing code that engineering teams actually want to ship.

With coding agents, do we increase or decrease the number of software jobs? (📈 IMO). @hansonwng and I had a fun chat with @sonyatweetybird and @laurenmhreeder about the future of Codex. Thanks for having us!.
Today on Training Data, @hansonwng & @embirico shared more about OpenAI Codex, how they see the sync and async development experiences merging, and @OpenAI's roadmap for longer-running agents with their own compute environments. Thanks for joining me and @laurenmhreeder!

Pretty cool to see this tracker of OSS PRs by agents hit HN today.(Didn't personally verify, but Codex stats seem credible)
