Best practices for Claude Code - Claude Code Docs

This is Anthropic's best-practices guide for Claude Code, and its central argument is that nearly every recommendation follows from one constraint: the context window fills quickly and performance degrades as it does. From that premise it lays out how to work with an agent that acts autonomously, including giving Claude a verification check so it can close its own loop, exploring and planning before coding, configuring CLAUDE.md, permissions, hooks, and skills, and managing context through /clear, compaction, and subagents. It is worth keeping as a practical reference for anyone moving from prompting a chatbot to delegating multi-step coding work to an agent.

optimAIzr - spend fewer tokens on the same work

This is the landing page for optimaizr, a free, open-source MIT-licensed CLI that reads token counts from the usage files Claude Code, Codex and opencode already write, then prices wasted tokens in dollars and applies accepted fixes such as compacting conversations earlier. Its headline evidence is the author's own profile: 55% of a $1,020 API-equivalent bill went to re-reading conversation context, and compacting at 200K reportedly cut cost per prompt by 26%, at the price of about seven minutes a day waiting for summaries. The page distinguishes "clear waste" from "likely" and "up to" savings and states that usage data stays on the machine, which is what sets it apart from other cost-tracking tools.

Your Mac has a powerful automation tool most people never open

macOS's built-in Shortcuts app offers a no-code way to automate tasks through a drag-and-drop interface that rivals Windows automation tools, making it accessible to users without programming experience. The app works by letting you stack pre-built actions together and then trigger them based on conditions like time of day or device connections, with support for third-party apps expanding what you can control beyond just system settings. The author demonstrates practical examples like auto-detecting keyboard connectivity to switch display layouts and launching focus modes when opening work apps, while noting the community at r/shortcuts showcases even more advanced automation possibilities.

4 ways AI can improve your thinking

Rather than using AI merely to automate routine tasks, this piece argues for leveraging it as a tool for deeper thinking and creation—such as using it as a devil's advocate to stress-test decisions, building personalized learning curriculums, generating visual concepts iteratively, and creating custom tracking dashboards without coding. The author provides specific prompts, recommended tools (ChatGPT, Claude, Gemini, Ideogram), and practical examples of how each approach can slow down work to challenge assumptions and build new capabilities rather than just work faster.

Broke? Busy? Bored? Presenting 31 Side Hustles (With Resources to Help You Get Started)

This comprehensive guide catalogs dozens of side hustle options across categories like freelancing, gig work, creative pursuits, and passive income streams, helping readers match opportunities to their available time, skills, budget, and income goals. The article emphasizes that the best side hustle depends on whether someone needs quick cash or long-term income, wants remote work, and what expertise they already possess. It provides practical advice on choosing and starting a side hustle, from identifying income goals to tracking expenses, plus explanations of earning potential and time requirements for each type of work.

AI Is Creating "Doom Loops" All Over the Economy

Unredacted legal documents from the New York Times' copyright lawsuit against Microsoft and OpenAI reveal internal company admissions that AI creates "doom loops"—systems where AI monetizes human-created content while simultaneously destroying the economic incentives and conditions needed to produce that content in the first place. The article catalogs these doom loops across journalism, music, film, education, and recruitment, showing how AI companies knowingly built business models that cannibalize their own supply chains and harm workers across creative industries. Microsoft's own internal documents acknowledged this paradox explicitly: the technology relies on fresh cultural content to function while the products themselves undermine creators' ability to earn livelihoods, ultimately threatening the open web and broader economy.

omlahore/RemoveMacAI: Debloat macOS: turn off Apple Intelligence, analytics, ads and pop-ups. A native app and CLI, and every change can be undone.

RemoveMacAI is a tool that lets users selectively disable Apple Intelligence features, analytics, ads, and various system annoyances on macOS while preserving changes that can be undone. It offers both a graphical app and command-line interface with preset configurations (Recommended and Maximum Privacy) that show users exactly what will change before applying modifications. The tool also recovers disk space by removing AI models, old installers, and cached files, and can export configuration profiles for enterprise deployment via MDM systems.

The Agentic Data Science Playbook – O’Reilly

When AI agents can conduct entire analyses independently, data scientists shift from executing every step to framing questions, equipping agents with proper context and tools, organizing how investigations proceed, reviewing results critically, and converting lessons into reusable expertise. The piece demonstrates this through examples like a fraud-detection model that initially reported excellent metrics (F1: 0.87) using a temporally mixed test set and a leaking feature—problems that emerged only when proper framing was supplied, dropping real performance to F1: 0.70. Success requires specifying the analytical task (not just desired outcomes), building skills that encode recurring methodological requirements, protecting evaluation from the agent's modifications through bounded experiments or competing analyses, using independent agent reviewers to challenge conclusions, and systematically preserving evidence trails so that corrections become standing guidance for future work.

Easier Bank Connections, a Faster AI Assistant, and more | Monarch

Monarch has streamlined switching between data providers for connected bank accounts, allowing users to move to better connections while preserving transaction history in just a few steps, and the platform now recommends superior providers when available. The AI Assistant has been upgraded to provide faster and more actionable answers about spending and financial goals, while a new automatic sorting feature keeps the accounts list organized by balance without manual intervention. Additional updates include the ability to add notes to accounts, elimination of duplicate Apple Card transactions on new iPhones, improved reporting detail pages, and several refinements across goals, tax tracking, and visual displays.

Traditional Web Development is Dead...(and Honestly? Good Riddance.)

Rather than traditional web development dying, AI and automation are simply the next layer of abstraction that will increase developer leverage—just as previous tools like frameworks and cloud services did before them. The real opportunity lies in shifting from "writing code" to "solving business problems," focusing on system architecture, product thinking, and AI integration rather than syntax proficiency. With AI handling routine boilerplate work, individual developers can now build complete products alone, making it feasible to launch micro-SaaS ventures or command premium consulting rates without needing entire teams.

Agents and products | Claude Marketplace | Claude by Anthropic

The Claude Marketplace allows enterprises to apply their existing Anthropic commitments across multiple Claude-powered software tools—including platforms for code review, app development, legal work, and data analysis—rather than managing separate contracts with individual vendors. This consolidation simplifies purchasing and budgeting while giving organizations access to vetted, enterprise-grade partners that can be added flexibly as needs change.

Our Favorite Indie Apps for iOS 27, Vol. 2 - MacStories

This roundup showcases five indie apps that have integrated Apple's latest AI and on-screen awareness features into their ecosystems. Bear now uses Siri to create and append notes with voice commands and screenshot annotation; Gentler Streak and The Outsiders provide fitness data summaries via Siri and Spotlight; Cheatsheet Notes lets you query and append to notes using Siri's understanding of on-screen content; and DoMarks makes saving and organizing URLs by category simpler through voice control and the "Surprise Me" feature to rediscover old bookmarks. The article emphasizes how these updates make common tasks more efficient by reducing manual steps and enabling hands-free interaction.
