Anthropic, OpenAI, Cognition, Sierra, LangChain and leading practitioners have jointly developed a canonical standard for building production-grade agentic products, codified in a new open-source repo…
Claude Code versions 2.1.154 through 2.1.158 contain a regression that corrupts the streaming delivery of tool results back to the model, causing results to arrive empty-then-late in bursts, duplicate…
A developer has created a set of 12 reusable configuration files for Cursor and Claude Code that encode consistent AI behavior patterns across projects. The files include specialized subagents for cod…
A developer has released Octorato, an open-source AI agent operating system designed to solve per-client cost attribution and workspace isolation in multi-tenant deployments. The system uses a single …
A developer built a Claude Code plugin that enforces brand voice rules by automatically scanning drafts for banned terms, em-dashes, and AI tells before publication. The plugin caught 31 em-dashes, 9 …
LiteLLM Labs released Lite-Harness, an open-source tool that runs AI coding agents like Claude Code, OpenCode, and Codex in a self-hosted sandbox with a unified CLI and API. The project consolidates m…
Every.to has released Compound Engineering, a plugin for AI coding tools including Claude Code, Cursor, Codex, and GitHub Copilot that introduces a structured workflow designed to make each engineerin…
Arch-decision, an open-source AI orchestrator, produces formal Architecture Decision Records (ADRs) from codebases in minutes by using a multi-agent system to explore code, generate approaches, and re…
Anthropic detailed two primary containment strategies for its Claude AI agent in an engineering blog post: human-in-the-loop supervision and access boundaries such as sandboxes, virtual machines, and …
A solo founder running a one-person operation relies on five core workflows from Claude Code's documentation to survive real-world development. The developer uses git worktrees to run parallel Claude …
An engineer built and shipped nine production AI agents over 14 weeks using only Claude Code's native extension layers — CLAUDE.md files, MCP servers, hooks, and subagents — with no external orchestra…
Simon Willison successfully ran Python ASGI applications in a web browser using Pyodide and Service Workers, overcoming a four-year limitation in his Datasette Lite project where JavaScript in `<scrip…
A developer found that the model powering AI coding agents is rarely the bottleneck in their failures—the real issue is that agents lack access to the project's live, structured context. After a year …
Harvard graduate Barak advised the Class of 2026 to master and extensively use AI tools like ChatGPT and Claude Code, regardless of their field of study. He urged graduates to treat AI critically as c…
A developer has identified a critical gap in the modern software stack, coining it the "Intent Layer" — the missing middle between user signal tools like Dovetail and Intercom and execution tools like…
A new marketing skill for Claude, built on a progressive disclosure architecture, achieved a mean pass rate of 82.7% across 26 evaluations, outperforming the baseline by 20.4 percentage points. The sk…
A developer released an open-source proxy tool called `claude-code-proxy` that lets users run Anthropic's Claude Code terminal harness using their ChatGPT Plus/Pro subscription or Kimi Code account in…
Fetch.ai released Fetch-Skills, an open-source command-line tool that allows developers to install curated AI agent knowledge into coding assistants with a single command. The tool, compatible with en…
A developer has built an open-source tool that treats AI agent "Skills" — Markdown files that instruct coding agents like Claude Code and Codex — as executable code rather than documentation for secur…
Anthropic's Claude Code with Opus 4.8 automatically identified and connected a developer's placeholder in a lesson file to a new component request, without being explicitly told to do so. The AI model…
