Developer tools news — AI coding assistants, IDEs, CLI tools, APIs, and productivity tools for software engineers. GitHub Copilot, Cursor, and more.
A hands-on course on agentic memory teaches developers to build agent loops that survive long runs and compound learning across runs using copy-paste Memanto commands for typed remember/recall, session handoffs, structur…
A developer documented a Claude Code MCP configuration pitfall in which a `timeout: 500` value (milliseconds) is silently ignored because values below 1000 fall through to the MCP_TOOL_TIMEOUT default of roughly 28 hours…
XNet Inc., a corporation run by one founder and AI, released Aiope, an on-device Android AI agent built over roughly five months and about 1,000 commits across 26 repositories, the company said. Aiope ships with 57 tools…
GitHub shipped Project HydraFusion into Copilot CLI on September 4, orchestrating models from multiple providers to draft, critique, and revise code rather than routing each request to a single AI model. In offline bench…
OpenComputer launched a service that lets developers define an AI agent in TypeScript and deploy it like a serverless function, with the company running the loop, Linux VMs, and durable sessions. The agent template impor…
A developer advocates replacing prompt-engineering tactics with a committed `.github/copilot-instructions.md` file that supplies Copilot with codebase-specific facts it cannot infer. The post argues rules should be durab…
Anton Shorygin, a QA lead with over a decade in software quality and test automation, reports that autonomous AI bug-fixing systems in production fail not because of model capability but because agents can game their own…
A developer building an answer engine optimization site for SearchD implemented llms.txt, JSON-LD, and AI crawler allowances, then tested whether each actually delivers the promised citation benefits. Testing 12 AI crawl…
A writer built a collection of interactive Chinese culture web tools on the $1 domain ChineseFortuneTools.online using ChatGPT, Claude and Codex, and connected the site to Google Analytics and Google Search Console to tr…
A developer released graphify-csharp, a free, MIT-licensed headless Roslyn/MSBuild indexer that gives coding agents compiler-accurate Find Usages for C#, resolving callers, references, implementations, inheritance, and o…
Agent Comms v2.2.0, a cross-harness communication mesh for LLM agents providing rooms, DMs, presence, and visibility over TCP, was published to the official MCP registry on 2026-09-12 and distributed as agent-comms on np…
The io.github.doublegate/cyberchef-mcp server, which exposes CyberChef's 504 data-transformation operations as MCP tools for encryption, encoding, and forensics, published version 4.1.0 to the official MCP registry on 20…
A developer has proposed applying circuit breaker patterns to agentic AI code review workflows to limit the blast radius of autonomous agents that can interpret, execute, and commit code. The approach uses a finite state…
A developer built wiki-sync-improvements.sh, a shell script that gates audit reports and improvement plans generated autonomously by Claude Code before they are synced into a personal Obsidian wiki. The script filters 12…
X-cmd released v0.10.9, adding project health reports to the `x install` command that surface Stars, OpenSSF Scorecard ratings, and activity over 30, 60, 90, 180, and 360 days to flag unmaintained open-source tools. The …
Building software specifically for AI agents will mostly fail because tools that work well for agents also work well for humans, existing tools hold a training-data advantage, and the ideal ergonomics for agents remain u…
Cognition's SWE-2 coding model scored 83.75% on the eight-task KingBench 3 benchmark, beating DeepSeek V4.1 Flash at 81.25% and its own base model Kimi K3 at 77.5%, according to independent testing. SWE-2 is post-trained…
AI agent harnesses — the tooling layer giving models file read/write and bash access — matter more to task completion than the underlying model, according to an analysis comparing Claude Code, Codex, and Hermes. The anal…
AI practitioners are advising developers to build model-agnostic agent skills — reusable instruction files, context documents, and plugins — so accumulated prompt and workflow expertise survives switching between harness…
A security researcher found that an attacker-controlled workspace containing a .git/ directory can escape the Cursor CLI's macOS Seatbelt sandbox and run code on a Mac with the logged-in user's full authority and no perm…
