This article details the updates to agent-shell version 0.47.1, a native Emacs mode for interacting with LLM agents powered by ACP. Key improvements include renaming 'claude-code-acp' to 'claude-agent-acp', support for new agents like Auggie, Cline, and GitHub Copilot, and experimental bootstrapped and resumable sessions. Enhancements have also been made to clipboard image handling, status display, image rendering, and table rendering. The update also introduces usage tracking, improved diffs, event subscriptions, and customizable context sources. The author encourages sponsorship to ensure the project's sustainability.
GitHub Agentic Workflows are built with isolation, constrained outputs, and comprehensive logging. Learn how our threat model and security architecture help teams run agents safely in GitHub Actions.
This post explains how we built Agentic Workflows with security in mind from day one, starting with the threat model and the security architecture that it needs. It details the defense in depth approach using substrate, configuration, and planning layers, emphasizing zero-secret agents through isolation and careful exposure of host resources. It also highlights the staging and vetting of all writes using safe outputs, and comprehensive logging for observability and future information-flow controls.

A new ETH Zurich study challenges the common practice of using `AGENTS.md` files with AI coding agents. LLM-generated context files decrease performance (3% lower success rate, +20% steps/costs).Human-written files offer small gains (4% success rate) but also increase costs. Researchers recommend omitting context files unless manually written with non-inferable details (tooling, build commands).They tested this using a new dataset, AGENTbench, with four agents.
Open-source coding agents like OpenCode, Cline, and Aider are solving a huge headache for developersOpen-source coding agents like OpenCode, Cline, and Aider are reshaping the AI dev tools market. And OpenCode's new $10/month tier signals falling LLM costs. These agents act as a layer between developers and LLMs, interpreting tasks, navigating repositories, and coordinating model calls. They offer flexibility, allowing developers to connect their own providers and API keys, and are becoming increasingly popular as a way to manage the economics of running large language models. The emergence of these tools indicates a shift in value towards the agent layer itself, with subscriptions becoming a standard packaging method.
Developers are replacing bloated MCP servers with Markdown skill files — cutting token costs by 100x. This article explores a two-layer architecture emerging in production AI systems, separating knowledge from execution. It details how skills (Markdown files) encode stable knowledge, while MCP servers handle runtime API interactions. The piece advocates for a layered approach to optimize context window usage, reduce costs, and improve agent reasoning by prioritizing knowledge representation in a version-controlled, accessible format.
PycoClaw is an open-source platform for running AI agents on microcontrollers. It brings OpenClaw workspace-compatible intelligence to embedded devices costing under $5. Built on MicroPython, it supports multi-provider LLM routing, multi-channel chat, tool calling, extensions, over-the-air updates, and battery operation.
Adafruit highlights the development of “pycoClaw,” a fully-featured AI agent implemented in MicroPython and running on a $5 ESP32-S3. This agent boasts capabilities like recursive tool calling, persistent memory using SD card storage, and a touchscreen UI, all built with an async architecture and optimized for performance through C user modules. The project is open-source and supports various hardware platforms, with ongoing development for RP2350, and is showcased alongside other Adafruit news including new product releases, community events, and resources for makers.
Agent Skills are a simple, open format for giving agents new capabilities and expertise. They are folders of instructions, scripts, and resources that agents can discover and use to do things more accurately and efficiently.
This article explains the concept of 'skills' in the context of language models, detailing how to create and use them to enhance model capabilities. It covers the file structure, YAML configuration, and integration of scripts for task automation, providing a practical guide for developers.
OpenSandbox is a general-purpose sandbox platform for AI applications, offering multi-language SDKs, unified sandbox APIs, and Docker/Kubernetes runtimes for scenarios like Coding Agents, GUI Agents, Agent Evaluation, AI Code Execution, and RL Training.
