Notes on design, technology, and life, told in depth while looking for quiet corners of the digital age.
Reasonix is a terminal AI coding agent designed specifically for the DeepSeek API. Rather than being a generic AI assistant wrapper, it deeply leverages DeepSeek's prefix caching mechanism with a cache-first architecture, minimizing the cost of repeated context to the extreme.
Recently, MDN officially launched its MDN MCP Server, which directly connects MDN docs and browser compatibility data to various AI tools—putting an end to guesswork when agents look up documentation and compatibility.
This article will introduce how to use Codex Subagents to develop a product from scratch. You will see how multiple agents collaborate to build a space shooter game that runs directly in the browser, covering the entire process from design documents, visual assets, to testing and validation.
This article introduces an efficient approach for repetitive programming tasks at scale: organize tasks into a CSV, have Codex launch independent subagents for each row to process in parallel, then write the consolidated results back to an output CSV. Whether it's batch-generating unit tests, checking compatibility for React Query upgrades, or translating comments across an entire project, this pattern turns what would normally be done one-by-one into a process that finishes in minutes.
Treat Codex Subagents as dedicated parallel teammates that handle the most time-consuming and easily overlooked exploration and verification tasks in daily coding, boosting your efficiency.
First principles thinking is a method of reasoning that starts from the most fundamental, irreducible facts and principles, rather than relying on experience, authority, or "that's how it's always been done."
Superpowers uses a variety of skills to train AI from a 'coding intern' into a 'professional engineer'.
In this post, we'll add a simple RBAC (Role-Based Access Control) rule to blog-demo.
In this part, we'll do three things: integrate a minimal login system (Auth.js / NextAuth style) into the project; require users to be logged in for creating new articles and posting comments in blog-demo; and in API Routes, retrieve the current user ID from the session instead of using a hardcoded authorId.
In previous parts, we took a backend-focused approach with Prisma to build the data model and business logic for blog-demo. In this part, we integrate that model into Next.js to create a minimal yet complete personal blog admin panel.
