Tame Dependabot: Group your updates, slow the cadence, keep security fast

If you maintain an active repository, you know the feeling. You open your notifications on a Monday morning and there they are: five, 10, sometimes a dozen Dependabot pull requests, each bumping a single dependency by a single patch version. Individually, every one of them is hel

Stacked sessions and pull requests in the GitHub Copilot app

I want you to look at this screenshot for a moment from the GitHub Copilot app. It’s a small one, it’s got a lot of icons, and it tells the most glorious story that I’m really excited about. This image is a set of stacked sessions. They’re a series of tasks in the same repository

Don’t stop early: Case-folding source code at memory speed

Suppose a user searches for café and your corpus contains CAFÉ, or they type straße and you’ve stored STRASSE. To make these count as matches, you need a canonical form that erases case distinctions, so that two strings which differ only in case compare equal. That form is case f

Turn one giant AI-generated pull request to a reviewable stack

Think about the last big feature you shipped. Be honest. Did you cram it into one giant pull request, or did you split it into smaller scoped pull requests? For years, you have silently had to decide between watching a pull request grow so large that reviewing it becomes a nightm

Understanding the brain with AI-driven explanations and experiments

At a glance LLM-based models can predict the human brain’s responses to language with high accuracy. But what drives that performance is essentially unreadable: a vast collection of learned parameters, not scientific theories anyone can read. Generative causal testing (GCT), deve

Memora: A Harmonic Memory Representation Balancing Abstraction and Specificity

At a glance Today’s AI agents don’t remember past interactions. They must repeatedly be fed relevant information or retrieve it from external sources, which becomes less efficient as they handle longer and more complex tasks. To scale agent capabilities, we need a more efficient

SkillOpt: Agent skills as trainable parameters

At a glance AI agents often fail because their instructions, or skills, are manually modified with no guarantee of improvement. SkillOpt turns skill editing into a training process, making agent behavior more reliable without changing model weights. SkillOpt treats an agent skill
