Claude-Code

Claude Code earned Anthropic significant developer mindshare — and significant revenue — by becoming the AI coding assistant of choice for software engineers who wanted something that could actually navigate a codebase. But a top Anthropic executive now publicly believes the company’s next major product will surpass it. In an interview with Bloomberg, the executive described Cowork — Anthropic’s general-purpose agentic assistant, currently in research preview — as the company’s “answer to general-purpose agentic AI” and expressed a clear expectation that it would reach a wider market than Claude Code ever did. ...

Sometimes the most revealing leaks aren’t the ones attackers engineer — they’re the ones that happen because someone forgot to add a line to .npmignore. That’s exactly what happened with Anthropic’s Claude Code v2.1.88. A developer named Chaofan Shou noticed that the npm package included a file it really, really shouldn’t have: main.js.map — a source map that, by design, contains a complete reconstruction of the original source code. By the time Anthropic patched it, GitHub mirrors had already spread. The community had 512,000 lines of TypeScript to dig through, and dig they did. ...

If you’ve been hitting Claude Code’s usage limits in 20 minutes instead of hours, you’re not imagining it and you’re not alone. The developer community has named it Cache-22: a prompt cache regression in recent Claude Code versions that’s causing Max-tier quotas to exhaust dramatically faster than expected. Anthropic has acknowledged the bug. A fix is in progress. In the meantime, here’s how to work around it. What’s Happening Prompt caching is supposed to save tokens by reusing previously-processed context instead of re-processing it from scratch every request. When it works correctly, it dramatically extends how far your token quota goes — particularly in agentic workflows with large context windows. ...

It happened again — and this time the exposure was massive. On March 31, 2026, security researcher Chaofan Shou (@shoucccc) discovered that Anthropic’s Claude Code CLI had inadvertently published its entire source code inside a 60MB source map file (cli.js.map) bundled within its npm package. Within hours, the community had mirrored the code, opened GitHub repos cataloguing the exposure, and the story had broken across cybersecurity news outlets worldwide. This is reportedly the second time in a year that Claude Code’s source has leaked through the same vector. ...

Today’s Claude Code source leak was a good reminder that shipping to npm is a security surface area that many developers don’t audit carefully enough. A 60MB .map file contained Anthropic’s entire CLI source. This guide shows you how to prevent the same thing from happening to your own packages. Why Source Maps Are the Hidden Risk Source maps (.js.map files) are generated by build tools like webpack, esbuild, Rollup, and Parcel to help with debugging. They map your compiled, minified output back to the original source. In development and CI, this is exactly what you want. ...

Anthropic just made a significant move to win the hearts of the open-source community: the company is giving away up to 10,000 six-month subscriptions to its top-tier Claude Max 20x plan — for free — to qualifying open-source maintainers and contributors. That’s roughly $1,200 in free AI access per developer, available through the new Claude for Open Source program. Applications are open now and close June 30, 2026. What You Get Claude Max 20x is Anthropic’s highest consumer subscription tier. It’s engineered for heavy workloads — complex multi-file coding sessions, long-context reasoning, and agentic workflows that run for extended periods. For developers who rely on Claude Code or API-heavy automation pipelines, 20x usage headroom is a meaningful upgrade from the standard plan. ...

Claude Code’s Auto Mode is one of the most practically useful features Anthropic has shipped for autonomous development workflows — and one of the least understood. This guide explains exactly what Auto Mode does, how its safety classifier works, when to use it versus manual mode, and what configuration patterns will keep your codebase intact. What Is Claude Code Auto Mode? Auto Mode is a Team-tier feature that gives Claude Code permission to auto-approve certain actions without prompting you for confirmation. That might sound alarming if you’ve worked with AI agents before — but the key is that “certain actions” is a carefully bounded category, enforced by a separate Sonnet 4.6 classifier model that runs before each action is executed. ...

If your Claude Code limits have been evaporating faster than they should, you’re not imagining things — and it’s not a bug. Anthropic has confirmed that usage during peak hours (5–11am PT on weekdays) now counts faster against your limits, a deliberate capacity management measure the company didn’t exactly announce with fanfare. The revelation comes after days of escalating frustration on GitHub and Reddit, where developers reported that sessions meant to last five hours were burning out in one or two. Some Max 20x subscribers saw their usage jump from 21% to 100% on a single prompt. ...

If your Claude Code usage limits are draining faster than you expect, you’re not imagining it and you’re not hitting a bug. Anthropic confirmed this week that usage consumed during peak hours counts at an accelerated rate against your monthly limit. The peak window: 5:00 AM to 11:00 AM Pacific Time, Monday through Friday. This guide covers what that means for your usage, how to track where your limit is going, and the practical strategies that actually help. ...

Figma just made a significant move: the design canvas is now open to AI coding agents via a native MCP (Model Context Protocol) server. As of this week, agents like Claude Code, Cursor, VS Code Copilot, Codex, and Warp can read your Figma files, understand the design structure, and generate code that maps directly to your actual components — not a screenshot approximation, but the live design graph. This is currently in free beta. Here’s how to get connected. ...
