Builders are shrinking their agent stacks: Lovable deleted most of its agent code and one engineer dropped all agent skills, citing Anthropic's 80%+ Claude Code prompt cut with no measurable eval loss.
The infrastructure gap is memory: every coding tool stores it differently, and several projects propose a shared format or an inspectable store.
Prefer to watch?
Builders report pruning agent code and skills as models improve, and the lighter harnesses they keep are small and inspectable.
Lovable's lessons from 100k PRs: choices that once helped can hold you back, so the team keeps rebuilding how the agent works.
Cites Anthropic cutting over 80% of Claude Code's system prompt with no measurable loss on its own evals, and argues skills can over-constrain the agent.
MIT-licensed core in C with the agent loop, tools and providers in Lua; works with Anthropic, Codex, OpenRouter or Ollama.
A 25-year programmer describes a local agent setup and says LLMs in agent harnesses became capable of full features in January 2026.
Argues today's agents do nothing until messaged and explores what a continuously running, environment-aware agent needs.
Memory is fragmented per tool, and new projects try a shared format or an inspectable filesystem-style store.
Each coding tool stores memory in its own shape and none can read the others; the post surveys existing formats and sketches a shared spec.
Open-source store that exposes knowledge, memory and skills as a viking:// virtual filesystem agents navigate with ls, tree, read and grep.
Keeps your verdicts on libraries, CLIs and MCP servers so the agent checks them before installing a tool you already ruled out.
Splits work in two: Elephant keeps project context and drafts the spec; Goldfish reviewers read it without the prior conversation to expose blind spots.
Go gateway that routes Claude Code, Codex, Ollama and cloud models through one endpoint and shows which app called what.
Offensive agent use is cheap and measurable, while new work targets model backdoors and agent-loop failure rates.
Analysis of ARTEX, an open-source LLM-driven pentesting platform, and how cybercrime campaigns used it at low model cost.
Explains how to read system-card cyber evals, including OpenAI rating GPT-6 Astra its first Critical-level cyber model in September 2026.
Most models still fail about half the time on multi-step tasks; models built on weaker bases loop almost twice as often.
Three techniques to block embedded triggers, plus a proposal to reuse backdoor methods as a security layer for users.
Two items show serving and tuning stacks moving beyond Nvidia and Python.
Runs full transformer inference on the GPU through Vulkan compute shaders, with no Python or CUDA, needing only vulkan-1.dll.
Fine-tuning runs on a 128-card Atlas 950 SuperPoD, per Pandaily.
