Anthropic introduced Agent Skills, a system allowing users and developers to package instructions, scripts, and resources into reusable folders that Claude loads contextually when relevant to a task. Skills are composable, portable across Claude apps, Claude Code, and the API, and can include executable code for tasks where deterministic programming outperforms token generation. The feature is available to Pro, Max, Team, and Enterprise users, with an API endpoint for programmatic management, and has been published as an open standard for cross-platform portability. Partner integrations with Box, Canva, and Notion are already live, and an open GitHub marketplace exists for community-built skills.
A TypeScript open-source project on GitHub implements a personal AI agent accessible via iMessage, supporting either the Claude Agent SDK or OpenAI Codex app-server as the underlying runtime. The agent includes memory, sub-agents, automations, and integrations. With 1,054 stars and 40 gained today, it represents a community-built example of multi-runtime agentic tooling targeting consumer messaging interfaces.
The Government of Alberta's Ministry of Technology and Innovation has used Claude Code with Opus and Sonnet models to conduct a large-scale security review of its 1,280 applications and 3,400 code repositories, scanning 466 million lines of code in approximately 20 hours using ~50 parallel agents. The team remediated vulnerabilities, rebuilt legacy systems (including a 25-year-old Java subsidy portal rebuilt in 4-5 days), and deployed continuous red/blue team review agents built on the Claude Agent SDK. Alberta has published technical white papers documenting the approach for other governments to replicate.
Anthropic has released Claude Sonnet 4.5, claiming it is the best coding model and strongest model for building complex agents, with a 61.4% score on OSWorld (up from 42.2% for Sonnet 4) and state-of-the-art performance on SWE-bench Verified. The release is accompanied by major product upgrades including checkpoints in Claude Code, a native VS Code extension, a Claude Agent SDK giving developers access to the same infrastructure powering Claude Code, and new context editing and memory tools in the Claude API. Pricing is unchanged from Sonnet 4 at $3/$15 per million input/output tokens. Early enterprise customers including Cursor, GitHub Copilot, Devin, Canva, and Figma report significant gains in coding, agentic, and long-context tasks.
Xcode 26.3 introduces native integration with Anthropic's Claude Agent SDK, enabling autonomous, long-running coding tasks directly within Apple's IDE. The integration supports visual verification via Xcode Previews, full-project reasoning across Apple frameworks, autonomous task execution with goal-directed behavior, and MCP-based access for Claude Code CLI users. This expands on an earlier September announcement that brought Claude Sonnet 4 to Xcode in a limited turn-by-turn capacity, now replacing it with the same agentic harness that powers Claude Code.
Anthropic and Infosys have announced a collaboration to develop enterprise AI solutions targeting telecommunications, financial services, manufacturing, and software development. The partnership integrates Claude models and Claude Code with Infosys Topaz to build agentic AI systems capable of handling multi-step tasks such as compliance reviews, claims processing, and code generation in regulated environments. A secondary focus is legacy system modernization, using the combined tooling to reduce migration costs. Anthropic also highlights India as its second-largest Claude.ai market and positions Infosys as an early partner in its expanded India presence.
Anthropic has released several major upgrades to Claude Code, including a native VS Code extension in beta, a refreshed terminal interface (version 2.0), and a checkpointing system that saves code state before each change to enable safe autonomous operation. The release also formalizes the Claude Agent SDK (formerly Claude Code SDK) with support for subagents, hooks, and background tasks, enabling parallel and long-running development workflows. Claude Sonnet 4.5 is now the default model powering Claude Code. These features collectively position Claude Code as a more capable autonomous coding agent for complex, multi-step software development tasks.
