RT @ClaudeDevs: We’re adding support for MCP Tasks and Elicitations in Claude.
Tasks let Claude give plugins long-running jobs such as deep research and report back when they’re done.

- Agent Skills started as an experiment in Claude Code. Many across the industry have come to adopt it, so we at Anthropic found it more fitting to donate it to the @AgenticAIFdn, next to MCP.ClaudeDevs @ClaudeDevsWe're donating Agent Skills to the Agentic AI Foundation (@AgenticAIFdn), the same foundation we donated MCP to. Since December 2025, 70+ agent platforms have integrated the standard, including ChatGPT, Cursor, GitHub Copilot, and VS Code. Here's what that means for you:266992.6K286K

Here's what that means for you:2974218.7K968K- Boris ChernyRT @claudeai: We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent. It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.04.2K06.9K
- Boris ChernyRT @ClaudeDevs: We launched OSS Scanner, which gives critical open source projects free, periodic vulnerability scans from our strongest models. Each finding includes a proof-of-concept, and a patch where possible.01.3K07.6K
- Boris ChernyRT @bunjavascript: In the next version of Bun bun lint is a 26x faster ESLint-compatible linter with over 1,000 builtin rules - reads eslint & oxlint configs.060011.1K
- Boris ChernyRT @ClaudeDevs: We keep improving performance across Claude, and you may have noticed it starts responding sooner! Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.074307.6K
- Boris ChernyRT @claudeai: Six projects from the last few weeks that caught our attention: A wildfire analysis prototype that maps the fire’s spread over time and tracks hot spots, made with Opus 5.5.02.3K06.6K
- Don't sleep on Claude Slides. This is how I make slide decks now -- no more googling "iphone frame svg" like the old days Try it:2021544.7K470K
- I could not imagine being productive without Claude Code Review. It runs on all of my PRs, and catches almost every bug before it goes it. This is a piece of the secret sauce that lets the team and I move so quickly while raising the quality barClaudeDevs @ClaudeDevsCode Review is now generally available for Claude Team and Enterprise plans. Reviews are now faster, catch more of the bugs that matter, and admins can pick from Quick, Standard, or Deep review levels for each repo.3541785K461K

2533847.3K1.2M - Over the last few years, we have made significant progress on prompt injection for Claude models. As agents do more, it is increasingly urgent that we solve it across the industry. Really excited to partner with Gray Swan to host this competition. Can’t wait to see what you find!Gray Swan AI @GraySwanAIIs prompt injection solved? Here’s $300,000 to find out. In partnership with @AnthropicAI, @Meta, @GoogleDeepMind, @Reflection_ai and our other frontier lab sponsors, @GraySwanAI is excited to announce the largest and most realistic AI red teaming challenge to date.

We often describe that as "being more ambitious" when using AI, which is tricky advice to follow. I wrote a tutorial:02.6K011.1K
- Boris ChernyRT @ChadMoran: What did @AnthropicAI do with his latest Claude Desktop update? I feel like there was a major system prompt/harness upgrade here. Opus 5.5 feels like it's Opus 5.8 now. cc @trq212 what did y'all do?020010.4K
- Boris ChernyRT @ClaudeDevs: We've been working hard on making the Claude Code desktop app great for running lots of sessions side by side. It's now much quicker to start sessions, easier to split work across a few, and you can always see what each of them is doing. Here’s what's new:091507.3K
- Boris ChernyRT @AnthropicAI: New on our Engineering blog: Creating in-house source control. In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale. Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months:02.7K07.8K
- Boris ChernyRT @ClaudeDevs: We just let in every Pro and Max user from the Claude Code Projects waitlist! If you're new to Claude Code Projects, here's a 4 minute walkthrough to get you started:082207.7K
- Boris ChernyRT @nateparrott: people really like the versions of Claude Design and Slides built into Claude — usage is much higher. we're doubling down there and folding standalone Design into Claude on December 14. before then — PLEASE tell me all the reasons the new one falls short and we'll fix em!023011.1K
- Boris ChernyRT @claudeai: Claude Dashboards and Claude Motion are in beta today. Ask Claude to turn your data into live dashboards and your ideas into animated explainers.04.6K06.8K
- Posts @bchernyIt was one prompt, claude verified pretty well too! No bugs so far
