Claude Code's Plan Mode: How It Works, Usage, and When to Skip It

·7 views

A guide explains Claude Code's Plan Mode, a setting where the AI reads a codebase and drafts its intended changes without editing any source files until the user approves. The author argues this prevents costly mistakes from confident but misdirected edits, such as a large multi-file diff that solves the wrong problem. Plan Mode can be activated via a keyboard shortcut, the /plan slash command, a startup flag, a settings file, or the desktop and web apps. The guide also covers its permissions, the approval menu, editing plans, and situations where it is better to skip it. The author notes that Claude Code changes frequently and that the official documentation, checked in late October 2026, should be treated as authoritative.

Two MCP tool captures diverged on the same server version due to launch settings

Two independent observers recorded different tool lists for the same mongodb-mcp-server version, with one capture showing nine extra write tools. The gap traced back to launch conditions: one sandbox started the server bare, while the other used a read-only flag and a connection string. Researchers Paraphern and HISTOR compared overlapping records covering 26 packages and found that most differences stemmed from how each capture was run. The comparison also uncovered measurement errors, including six stale snapshots that were re-captured from clean environments. The authors argue that launch arguments, network access, and authentication context should be recorded alongside tool definitions.

Python Walkthrough of LeetCode's Two Sum Problem Using a Hash Map

A DEV Community post explains LeetCode problem #1, Two Sum, an easy array task. The problem asks for the indices of two integers in an array that add up to a given target, with exactly one valid solution and no reuse of the same element. The author presents a Python solution that stores previously seen values in a dictionary and checks each new number's complement against it. The post notes that time and space complexity are left for a forthcoming video. It also promotes a DSA Decoded YouTube channel and GitHub repository, and invites readers to share alternative approaches.

Svelte Compiles Components to Plain JavaScript, Shipping No Framework to Browsers

Svelte differs from React, Vue, and Angular by acting as a compiler that converts components into plain JavaScript at build time rather than shipping a runtime framework. This approach yields smaller bundles and faster pages, with reactivity handled through simple variable assignment instead of hooks or setter functions. Component markup, scripts, and styles are kept together in familiar languages, and styles are automatically scoped to each component. The article notes trade-offs, including a smaller ecosystem, fewer libraries and job listings, and reactivity rules that can confuse beginners. It concludes that Svelte's simplicity suits personal projects and size-sensitive sites, and that its ideas have influenced React's compiler work.

Why a USB-C Hub Can Leave Your Laptop Losing Battery While Plugged In

A hardware manufacturer explains that a 100 watt USB-C hub reserves roughly 12 to 20 watts for its own electronics, so the laptop receives less power than the charger's rating. Laptops that need more than the hub's advertised passthrough figure, such as some 16-inch models under load, will slowly drain while connected. Suggested fixes include charging directly through a second port, using a higher-wattage charger, or reducing the number of bus-powered devices on the hub. The article also notes that 4K at 60 hertz consumes more shared bandwidth than 4K at 30 hertz, which can slow attached peripherals and drives. Hubs that run hot may have a poorly designed conversion chip, a warning sign of potential failure.
