<li><strong>OpenAI’s internal harness engineering for large-scale software</strong>: OpenAI has unveiled “Harness Engineering,” an internal AI-driven methodology that uses Codex agents to handle large-scale software development tasks, including code generation, testing, and CI workflows. A five-month internal experiment reportedly shipped a beta product with one million lines of code, all generated without manual source code. This shifts the engineering role to designing environments and specifying intent, with structured feedback via declarative prompts, as noted by Martin Fowler. <a href="https://app.daily.dev/posts/dPCNsAxds" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Anthropic clarifies ban on third-party Claude tool access</strong>: Anthropic has updated its legal documentation to explicitly ban third-party tools from accessing Claude subscription accounts, a policy that has technically been in place but widely ignored. This move, which began enforcement in January 2026, aims to protect Anthropic’s revenue model from token arbitrage, forcing tools like OpenCode to remove support for Claude subscription keys, according to The Register. Meanwhile, OpenAI publicly endorsed third-party harness use with its own Codex subscriptions. <a href="https://app.daily.dev/posts/vOr3Aub97" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>EFF updates open-source policy for AI-assisted coding</strong>: The Electronic Frontier Foundation (EFF) has updated its open-source contribution policy, requiring contributors to fully understand submitted code and ensure all comments and documentation are human-authored. This approach, praised by analysts for sidestepping the “unsolvable AI-detection problem,” shifts accountability to the contributor, who must be able to explain their code if asked. The EFF’s strategy emphasizes disclosure and accountability over AI detection, as reported by The Register. <a href="https://app.daily.dev/posts/W3yzAhjLd" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>

<li><strong>Meta’s AI identity verification is a dumpster fire</strong>: A digital marketing agency reports that Meta’s AI identity verification system is auto-banning legitimate work accounts, often before any ad activity, with appeals being impossible. Apparently, Meta’s brilliant AI can’t tell the difference between a bot and a paying customer, but hey, at least it’s consistent in its incompetence. <a href="https://app.daily.dev/posts/llEdpZB7r" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Unity CEO says AI will make entire games</strong>: Unity’s CEO claims AI will soon enable prompting full casual games into existence, which sounds great if your idea of a game is Flappy Bird. While AI might be good for rapid prototyping, let’s not pretend it’s replacing actual game developers anytime soon, unless we’re aiming for a future filled with procedurally generated mediocrity. <a href="https://app.daily.dev/posts/VkFal2xDM" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>OpenAI promotes local codex developer meetups</strong>: OpenAI is promoting community meetups for Codex, encouraging developers to “create and ship projects.” Because nothing says organic community building like a corporate-sponsored meetup to push their product. It’s almost like they want you to build their ecosystem for them, for free! <a href="https://app.daily.dev/posts/kpaXVeVV9" target="_blank" rel="noopener nofollow">Read more</a></li>
