Attackers increasingly target the packages, editor extensions, and AI tool configs on developer machines and not just production systems. Perplexity has open-sourced an internal tool it uses to address this problem. Perplexity released Bumblebee on GitHub. The tool is a read-only inventory collector for macOS and Linux developer endpoints. It is written entirely in Go and carries zero non-stdlib dependencies. Perplexity already uses it internally to protect developer systems behind its search product, Comet browser, and Computer agent. […]

Instruction-tuned language models refuse harmful requests. But which part of the model is actually responsible — and how does that mechanism get installed during training? A new research from Nous Research team takes a neuron-level look at this question. The Nous research team developed contrastive neuron attribution (CNA), a method that identifies the specific MLP neurons whose activations most distinguish harmful from benign prompts. By ablating just 0.1% of MLP activations, they reduced refusal rates by more than […]

On the <dl> I learned a few new-to-me things about the <dl> element from this article by Ben Meyer: A <dt> can be followed by multiple <dd> You can optionally group the <dt> and <dd> elements in a <div> for styling – but only a <div>. You can label them using ARIA. They’ve been called “description lists”, not “definition lists”, since an HTML5 draft in 2008. So this is valid: <h2 id=”credits”>Credits</h2> <dl aria-labelledby=”credits”> <div> <dt>Author</dt> <dd>Jeffrey Zeldman</dd> […]

Tencent has released TencentDB Agent Memory, an open-source memory system for AI agents. The project ships under the MIT license. It targets a problem familiar to anyone shipping long-horizon agents: context bloat and recall failure. It is symbolic short-term memory along with layered long-term memory. It integrates with OpenClaw as a plugin and with the Hermes Agent through a Gateway adapter. The default backend is local SQLite with the sqlite-vec extension, so no external API is required. Why […]

In this tutorial, we build an advanced workflow using the SuperClaude Framework as a structured layer on top of the Anthropic API. We clone the framework, discover its commands, agents, and modes, and create a Python bridge that dynamically loads the relevant Markdown behavior files into the system prompt before each model call. Through practical examples, we explore brainstorming, frontend implementation, security analysis, business strategy, deep research planning, token-efficient responses, and a chained multi-step development workflow with session […]

I ran jscpd against 49 vibe-coded GitHub projects looking for code duplication patterns. Average duplication: 7.98% (above the 3-5% industry benchmark). But the unexpected finding wasn’t in the apps — it was in the skill libraries built to teach AI agents how to code. Those have 30-40% duplication rates, mostly in markdown instructions and CSS templates duplicated for different agent platforms. The infrastructure designed to enforce AI discipline embodies the same pattern it’s trying to prevent.
