ai coding

"AIエージェントによるコーディングが日常になり、同時に複数のエージェントを走らせて作業する機会も増えた。しかし、エージェントごとにシェルを立ち上げてworktreeを切り、ブランチを管理し、エディタと行き来する作業は手数が多い。本記事では、tmuxを軸にworkmuxとsidekick.nvimを組み合わせ、ターミナルだけで完結するAIコーディング環境を構築する手順を解説する。"

"I gave it a 40-line order processing function, and what came back was a 120-line code with the Decimal class, dataclass, logging module, type hints, and Strategy pattern added."

"By describing things as 'Absolute Rules' in CLAUDE.md like this, Claude Code will spontaneously start checking for them. For example: 'Never commit files containing API keys, passwords, or tokens (.env, credentials.json, etc.).'"

"psmux is a native terminal multiplexer for Windows written in Rust. It uses Windows ConPTY directly (no WSL, Cygwin, or MSYS2 required) and speaks tmux commands as-is, allowing users to split panes and launch Claude Code in each one."

"Opus 4.7 introduced a new tokenizer, increasing token consumption by up to 35% for the exact same prompts (according to a Finout.io survey)."

"AIが勝手に全部やってくれる「自律」も魅力的ですが、実際の複雑なプロジェクトでは、人間が「指揮者」として手綱を握る「協調」の方が、結果として爆速で、かつバグのない開発が可能です。"

"AI is not the 'app killer', but rather an 'app production accelerator'. AI-assisted development tools are significantly lowering the threshold for software creation, allowing more creators without traditional programming backgrounds to participate in mobile app development."

"Claude Code is Anthropic's terminal-based AI assistant. It allows you to proceed interactively, from creating and editing files to executing commands, so you can advance your environment setup just by telling it what you want to do."

"When I switched from ChatGPT to Claude, the development pace changed completely. The parts I was stuck on started resolving smoothly, and from not knowing what Laravel was, I was able to build the framework of the service."

"The theme of NTT Research's annual user event, Upgrade, in San Jose this week was “Research to Reality,” a reflection of NTT’s desire to balance the academic nature of research with the practicality of ensuring the outcome is something customers can use and benefit from."

"Cursor will train Composer 2.5 using xAI's GPUs, marking a significant investment in computational resources."

"I’m not trying to sell anything, I’m mainly using it as a learning project to practice..."

"Harness engineering is a method for improving the output quality of AI agents through the design of the surrounding environment (rules, commands, workflows) rather than just the prompt itself. In my case, I configure it with just three commands: log → distill → promote."

"Factory, a startup developing AI agents for enterprise engineering teams, announced it had raised $150 million at a $1.5 billion valuation."

"Codex can now operate in the background on your computer — opening any app on your desktop and carrying out operations with a cursor that clicks and types."

"In this article, we introduce a method to teach ScalarDB implementation rules to Claude Code to generate accurate code. Alongside, we reveal why having AI generate Saga or TCC code doesn't work well, based on the content from the previous articles."

"codex-plugin-cc (Method 2/3) internally uses the App Server Protocol (ASP). ASP Mode features a resident app-server-broker.mjs, uses JSON-RPC 2.0 over stdio/WebSocket, and enables thread continuation via threadId."

"Rather than being a simple trick to reduce prompt character count, this article is a summary of the engineering practices I implemented to suppress token consumption, born from the context bloat problem I actually faced while heavily abusing Claude as a daily development partner."

"639 hooks are there for choice. Node.js developers need React hooks. Python developers don't. Docker users need docker-prune-guard."

"HTML and CSS I could write. But Laravel was at a level where I'd ask, "What's that?" It was someone like that who met Claude Code and created Japan's first web service."

"200-line stack traces become a single line: 'Promise reject is unhandled. await is missing on line 42.'"

"With this update, the 'Thinking' hints are now displayed from the early stages of the process... quick feedback makes a huge difference in peace of mind."

"Copilot has evolved from a 'mere code completion tool' into an 'autonomous development partner.'"

"There is no need to choose just one. Understanding their strengths and using them together is the optimal solution right now: Claude Code is overwhelming for large-scale changes across multiple files and architecture design; Cursor is supreme for smooth daily coding and IDE integration; GitHub Copilot Agent shows its true value in automation on existing GitHub workflows."

"The year 2026 is being called 'the year of practical application for AI coding agents,' with major tools simultaneously undergoing massive updates... moving from 'whether to use them' to 'which one to use.'"

"I did 'vibe coding' to create a website I wouldn't have attempted otherwise... and put several long-shelved projects back on the agenda..."

"I told Claude Code: 'Make it at a level where it can be published and used by others.' Claude Code automatically read the entire codebase, compared it with production scanners like OWASP ZAP and Semgrep, identified the gaps, and generated a 5-phase implementation plan."

"The hottest new programming language is English"

"Claude is dedicated to refining the specification as a 'smart consultant,' while implementation is left to free Agents as much as possible—this is the core of this workflow."
