Developer tools news — AI coding assistants, IDEs, CLI tools, APIs, and productivity tools for software engineers. GitHub Copilot, Cursor, and more.
A developer argues that workflow engines, which hold control flow in their own process and invoke coding agents as subroutines, offer machine-checkable control flow that orchestrator skills written as Markdown prose cann…
A developer at LeanZero fine-tuned Qwen3-27B to write Atlassian Forge apps, raising identifier accuracy from 15% to 69% and Forge manifests passing Atlassian's validator from 0 of 25 to 14 of 25, with 12 of 25 complete a…
A developer has demonstrated Microsoft Office running on Linux through Wine with no virtualization, using Nix Flakes and the latest GE-Proton, with the work largely performed by Claude Code with Fable under a Claude Max …
Anthropic launched a redesigned Projects feature in Claude Code in beta, turning a project into a single coordinator conversation that spawns parallel cloud sessions called threads, each running on its own branch and rep…
Bend 2 has launched with a new `LAWS.bend` file that forces AI coding agents to write mathematical correctness proofs, using Bend's compiler to guarantee declared rules always hold. The language's developers claim Bend c…
A developer ported a 2,150-line bash agent that orchestrates command-line tools, calls a model, and reshapes JSON into 2,258 lines of Python, finding that the rewrite cut actual code by 40% while adding comments and docs…
Bend, a new programming language that compiles to native code and uses a Lean-style proof checker to block AI coding mistakes, has launched with an install script at bend-lang.com/install.sh. Bend runs nearly as fast as …
A new MIT-licensed plugin called gh-review-loop for Claude Code and Codex clears AI code-reviewer feedback on GitHub pull requests from the terminal, fixing flagged bugs plus unflagged sibling instances and gating each p…
A developer released Full Stack HQ, an open-source, permission-first engineering workflow that provides a shared rule core across Claude Code, Google Antigravity IDE, and OpenAI Codex. The stack bundles 10 specialist age…
A developer released My Shell, a Vim-keybinding terminal agent that completes full tasks in 20–80k tokens instead of the 300k+ prefill tokens typical of most agent sessions, according to the project's Show HN post. My Sh…
A developer describes accidentally building a "dark software factory" called Holodeck after struggling to keep Claude Code running for extended periods without stopping or suffering context drift. The solution involved f…
Two open-source projects, Quire and Texio, have emerged on GitHub to enable human-AI collaborative editing in Markdown workflows, according to their repositories. Texio is designed for AI agent Markdown manipulation with…
MCPJam launched a testing platform for Model Context Protocol servers that provides observability into agent interactions, according to MCPJam. The platform targets observability gaps where creators cannot see what users…
Fivetran released a beta CLI tool that lets humans and AI agents orchestrate the platform via command-line and API without using the web user interface. The tool exposes most platform functionality in a machine-friendly …
A newly disclosed vulnerability dubbed Plugin4Shell enables zero-click remote code execution in Claude Code, OpenAI Codex, GitHub Copilot, and Gemini CLI by bypassing plugin SHA pinning, according to the security researc…
Alibaba has open-sourced Open Code Review (ocr), an AI code review tool it says has been battle-tested internally for two years across tens of thousands of developers. The tool pairs a deterministic engineering engine fo…
Anthropic launched updated Claude projects in beta for select Claude Pro and Max subscribers using cloud sessions in Claude Code, with access expanding to more Claude Code users on those plans over the coming week and to…
Google and Speakeasy have open sourced Speakeasy's OpenAPI code generation suite under the AGPLv3 license, following the abrupt shutdown of Google's previous SDK generation provider in May 2026. The partnership migrated …
Anthropic relaunched Projects inside Claude Code on September 17, giving developers a coordinating agent that splits a single engineering goal into multiple parallel Claude Code sessions, called threads, each running as …
A developer built pi-jev-auto-mode, an extension that gates the Pi terminal coding agent's bash, write, and edit calls through a rule layer plus TypeSafe's Jev decision-only probability model, which returns calibrated sa…
