Developer tools news — AI coding assistants, IDEs, CLI tools, APIs, and productivity tools for software engineers. GitHub Copilot, Cursor, and more.
A developer built a tool that counts AI co-authored commits by parsing Co-Authored-By trailers in git history, finding that 10,261 of their 26,251 commits (39%) were co-authored by Claude. The project also uncovered an u…
Ds4 now supports directional steering, a runtime activation edit that applies a normalized f32 direction per transformer layer during inference, with steering files shaped 43x4096 for DeepSeek V4 Flash, 45x4096 for GLM 5…
A developer has published a detailed mental model for Next.js caching in 2026, breaking down the framework's four distinct caching layers: request memoization, the data cache, the full route cache, and the router cache. …
A developer has published a CI-runnable script that fetches a gateway's pricing.usd.json file and flags near-duplicate model identifiers whose cache-read prices diverge, after finding that strings like claude-fable-5 and…
A developer open-sourced CerebrumKit, a framework that moves agent topology — tools, skills, agents, and workflow graphs — out of source code and into database tables so domain experts can edit agent behavior without red…
A developer argues that AI coding assistants, agents, and model stacks are accelerating software supply-chain risk by introducing untrusted packages, hallucinated dependency names, and unattended installs into build pipe…
A developer built Incident Context, an incident-investigation agent that models operational records — services, deployments, changes, runbooks, and incidents — as connected Sanity documents and traces explicit relationsh…
A developer identified and fixed a KV-cache offloading bug in vLLM that caused incorrect chunking for models with mixed KV-cache groups. The existing implementation assumed a single KV-cache group layout and relied solel…
A developer writing under the handle mrsaynothing reports that an agent-driven pipeline has published, deployed, and translated posts on their personal site for nineteen consecutive days with zero missed slots and zero r…
A developer running a Telegram bot on Google's Gemini free tier described building a three-layer quota protection system after a single user sent 1,400 messages in three hours and exhausted the API's 1,500 daily requests…
Docker Sandboxes introduce a new trust boundary for AI coding agents by running them inside a microVM with its own kernel and Docker Engine, mediating host access through explicit workspace, credential, network, skills, …
Microsoft released Skill Recorder, an Electron app that records a user's screen and activity locally and, upon clicking Analyze, uploads window titles, URLs, clipboard previews, extracted screen images, and narration tex…
A developer built vscode-border, a free, open-source C++ Windows application that draws a colored border around each VS Code window to distinguish them when multiple repos and worktrees are open. The tool also adds repo/…
A security researcher known as ferstar documented that ZCode, an AI coding desktop app from Zhipu, silently packaged entire Git repositories—including full commit history and LFS assets—into encrypted archives and attemp…
A tutorial published on GitHub repository ritog/harmonic demonstrates training a Hamiltonian Neural Network to simulate the phase space of a harmonic oscillator — a rigid pendulum defined by mass m, rod length l, angle q…
Engineering manager jbreu published Autopoiesis, a proof-of-concept on GitHub that ships a fully configured AI platform inside a repository using containers, configs, and scripting in roughly 20 KByte of unoptimized over…
A developer published a demo showing how the OWASP Core Rule Set (CRS), running via Coraza inside Solo Enterprise for agentgateway, can inspect LLM prompts and MCP tool calls rather than just URLs and headers. The setup …
A developer benchmarked TypeSafe AI's Jev model on a 60-case agent tool-call risk classification task, finding both jev-latest and jev-preview at 91.7% accuracy with no statistically significant difference between them a…
Zizka-ai released ZizkaDB, an open-source, self-hosted audit trail for AI agents that logs each agent step with a parent_id so teams can trace a tool call or response back to its root cause. The stack ships via a Docker-…
StoreReady launched as a Show HN comparison tool that scores AI app builders on their ability to clear Apple App Store review, publishing head-to-head verdicts on six pairs including Rork vs Vibecode, Rork vs a0.dev, Vib…
