Andrej Karpathy offers a free 29-minute walkthrough on Software 3.0, detailing how to set up an AI-driven code factory with Claude Code that ships features autonomously. He packs the same insights that cost Anthropic millions into a DIY build guide—no recruitment fees or exclusive deals required.

Two Anthropic engineers walk through every lesser-known Claude Code capability in a 24-minute session. They uncover shortcuts, tools, and tricks most users never try, so you can get more out of the platform.

The creator of Claude Code hosts a free 30-minute workshop showing how to use 40 hidden Claude commands effectively. Watch the session, bookmark it, and then follow the linked guide for step-by-step instructions.

Anthropic investigated user reports of degraded performance in Claude Code, the Agent SDK, and Cowork, and traced them to three separate changes: a lowered default reasoning effort, a bug that cleared session context on every turn after idle, and a prompt tweak to limit verbosity. All issues were reverted or fixed by April 20 (v2.1.116), and Anthropic is adding stricter testing, broader internal dogfooding, and more targeted evals to prevent similar regressions.

Claude Code Auto Mode automates permission checks by assessing the risk of each action instead of prompting you every time. It blocks or escalates unsafe operations—like mass deletions or external network calls—while allowing routine tasks to run headlessly. This differs from the dangerous “skip permissions” flag, which removes all guardrails.

This article reviews Anthropic’s free Claude Code in Action course, detailing its 15 video lectures, final quiz, and completion certificate. It explains setup, context management, hooks, MCP servers, and GitHub integration, noting its value for both beginners and experienced users.

Anthropic reduced Claude Code’s prompt cache TTL from one hour to five minutes, causing higher token write costs and faster quota depletion for long coding sessions. Developers report frequent cache misses—especially with large context windows—hitting usage limits and degrading performance. Anthropic says it will tweak default context windows but won’t offer a global TTL setting.

Anthropic has introduced repeatable routines in Claude Code that run on its web infrastructure, so tasks execute even if your Mac is offline. The feature, now in research preview, lets Pro, Max, Team, and Enterprise users schedule automations with repo and connector access, subject to daily run limits. The update also includes a redesigned Mac app with parallel sessions, an integrated terminal, file editing, and preview tools.

This article shows how to set up Google’s open-source Gemma 4 coding model in Anthropic’s Claude Code via Ollama Cloud or locally. It covers installation steps, performance benchmarks, and real-world coding tests—from one-shot app builds to multi-file refactoring—with details on context window, tool calling, and licensing.

Anthropic is revamping its Claude Code desktop app under the “Epitaxy” codename, adding multi-panel views for Plans, Tasks, Diffs and support for multiple repositories. It also introduces a Coordinator Mode that lets Claude orchestrate parallel sub-agents and create custom agents in-app, mirroring OpenAI’s Codex agent workflow but running locally on the desktop.

The article breaks down the recently leaked source code of Anthropic's Claude Code CLI. It highlights the system's architecture, design choices, and differences from OpenAI's Codex, particularly in handling context overflow and user interactions. Key features like compaction strategies and internal versus external user instructions are explored.

The Humanizer skill for Claude Code transforms AI-generated text into more natural, human-like writing by addressing common patterns found in AI writing. Users can easily install the skill and apply it to their text to improve clarity and authenticity.

Boris Cherny shares his efficient setup for using Claude Code, highlighting the importance of customized workflows and verification processes. He details various strategies, such as running multiple sessions in parallel, using slash commands, and maintaining a shared repository for continuous improvement.

A detailed overview of Claude Code, showcasing its key features and functionalities, including slash commands, memory, skills, and advanced tools. The article provides a structured learning roadmap and practical examples to help users maximize their experience with Claude Code.
