Claude Code Adds Plugin Evals for Regression Testing and No-Plugin Baselines
Claude Code now includes `claude plugin eval`, a testing workflow for plugin and skill authors. The command can create cases and graders, run a plugin in isolated non-interactive sessions, compare results with a no-plugin baseline, generate an HTML report, and support CI gates for plugin changes. Evals require Claude Code v2.1.269 or later and consume model usage.
Claude Code Desktop Adds Pop-Out Panes for Diff and Terminal Work
ClaudeDevs says Claude Code Desktop can now pop out any pane into its own window. You can move a diff or terminal to another screen while Claude keeps working, dock it back later, and run sessions side by side or stacked.
Claude Computer Use Runs in the Background in Cowork and Claude Code
Anthropic added computer use to Claude Cowork and Claude Code in the Claude Desktop app. Claude can click, type, open apps, and use dev tools while you keep working on macOS, with Windows support also documented. The beta is limited to Pro and Max plans and still requires the desktop app to be open and the computer awake.
Claude's ant CLI Can Now Manage Agent Resources as Code
Anthropic added `ant apply` to the Claude CLI, letting teams declare Managed Agent environments, agents, skills, memory stores, and deployments in a repository and reconcile them with the Claude API.
Anthropic Open-Sources a Commerce Agents Blueprint for Claude
Anthropic has launched an open-source blueprint for building commerce agents with Claude. It includes shopping and merchant agent implementations, demos across retail, travel, telecom, and ticketing, guardrails, and a Claude Code plugin.
Claude Code Desktop Can Now Resume Sessions Started in the Terminal
Claude Code can now move a terminal-started session into the Claude Code desktop app. Anthropic says users can type /resume, choose a CLI session, and continue with the full conversation and context intact.
Anthropic Opens a Claude Team Plan for Scientists With Free Standard Seats
Anthropic opened a Claude Team plan for scientists on August 27, 2026.

Claude Code Weekly Limits Are Now 25% Higher Permanently: Anthropic Confirms the September 14 Change
As of September 14, 2026, Anthropic documents the permanent increase on its own support article: weekly limits in Claude Code are 25% higher than they were before the May-September promotion for Pro, Max, Team, and seat-based Enterprise plans. The 50% promotion ended September 13 at 11:59 PM PT. Five-hour limits, prices, and other Claude products are unchanged.
Claude Code Remote Control Can Start Sessions From Your Phone
As of August 2026, a machine running claude remote-control appears as a device card at the top of the Code tab in the Claude app: tap it, pick a directory, and a session starts on that machine. Anthropic's Week 34 digest also took Remote Control out of research preview. Code and files stay local.
Claude Code Desktop Adds Auto-Continue After Usage Limits
Claude Code waits in the open session and continues your task automatically when a claude.ai usage limit resets. It is on by default from version 2.1.234 in interactive sessions signed in with a claude.ai subscription. Turn it off in /config under 'Continue automatically at usage limit' or set autoContinueAtUsageLimit to false. It resumes work; it does not raise the limit.
Codex Can Import Workflows From Other AI Agents
OpenAI now lets the ChatGPT desktop app and Codex CLI import supported setup and recent work from other agents. The desktop app can import from Claude Code, Claude Cowork, and Cursor, while Codex CLI supports Claude Code and Cursor, with automatic updates and import history available in the desktop app.
Claude Code Will Make Auto Mode the Default on August 14
As of September 2026, auto mode is the default permission mode for new Claude Code sessions on Pro, Max, and Team plans; the switch took effect on August 14, 2026, as Anthropic announced on August 7. Enterprise plans, Console API keys, and the Bedrock, Agent Platform, Foundry, and Claude Platform on AWS integrations still start in manual (default) mode. The mode routes tool calls through a safety classifier, keeps manual approval available, and does not charge Pro, Max, or Team for classifier calls.
Claude Code Sessions Can Now Message Each Other
Claude Code lets independent sessions discover and message one another, with controls for holding, refusing, or approving incoming messages. As of August 2026, sessions can also start conversations with sessions on other machines or Claude Code on the web, and native Windows is supported; the August 7 launch allowed only replies across machines and covered macOS and Linux. Messaging is on with nothing to enable; a held message in a headless session now expires after five minutes by default.
Claude Code artifacts can now call MCP connectors for live, viewer-specific data
Claude Code artifacts can call MCP connectors each time someone views them, so a published page shows current data rather than a session snapshot. Available on Pro, Max, Team, and Enterprise plans, requiring Claude Code v2.1.209 or later. Connector-backed artifacts cannot be shared to a public link on any plan.
Claude Code Desktop Adds an iOS Simulator Pane: Watch Claude Test Your App Live
Claude Code Desktop opens Apple's iOS Simulator in a pane beside your conversation when Claude builds or checks your app, taps through it, and reads the screen to verify its own changes. Public beta on macOS for Pro, Max, Team, and Enterprise plans; needs Claude Desktop v1.24012.0+ and Xcode 26.x, not Xcode 27.
Claude Code Ships Screen Reader Mode: Plain-Text TUI for VoiceOver and NVDA
Claude Code now has an opt-in screen reader mode that replaces boxes, spinners, and in-place redraws with labeled linear text that VoiceOver and NVDA read in order. Turn it on with the --ax-screen-reader flag, the CLAUDE_AX_SCREEN_READER env var, or the axScreenReader setting (v2.1.181+). Menus become numbered lists, a terminal bell signals when Claude needs you, and separate settings cover magnifiers, reduced motion, and colorblind themes.
Claude Code Artifacts Expand to Pro and Max Plans (Private by Default)
Anthropic's ClaudeDevs says Claude Code Artifacts are now available on Pro and Max plans. The Claude Code docs now list Pro/Max/Team/Enterprise as eligible, with Pro/Max artifacts remaining private to the individual user.
Claude Desktop for Linux Beta: Ubuntu and Debian, With Caveats
Anthropic shipped a beta of the Claude desktop app for Linux on Ubuntu 22.04+ and Debian 12+ (x86_64 or arm64), with Chat, Cowork, and Claude Code on all paid plans. The app does not self-update; updates arrive through apt, and as of August 2026 a directly installed .deb registers the repo itself. Computer Use and Dictation are missing.
Claude Sonnet 5 Launch: Anthropic's Most Agentic Sonnet, Now the Default Tier
Anthropic launched Claude Sonnet 5 on June 30, 2026, calling it its most agentic Sonnet yet -- it plans, drives browsers and terminals, and runs autonomously. It is the default for Free and Pro, available across all plans, in Claude Code, and on the API as claude-sonnet-5. Anthropic later made its $2 per million input and $10 per million output token pricing permanent.
Claude Code Adds Artifacts: Live, Shareable Pages for PR Walkthroughs and Dashboards
Anthropic introduced Artifacts in Claude Code, letting Team and Enterprise orgs turn an in-progress Claude Code session into a live web page that updates as the session progresses and can be shared privately within the organization.
Claude Design's `/design-sync` Makes Claude Design and Claude Code a Two-Way Workflow
Anthropic's `/design-sync` pulls your design system into Claude Design so everything Claude builds starts from your real components, and keeps work synced as you move between Claude Design and Claude Code. You can start in either surface, hand a finished design off to Claude Code, and continue from existing work instead of a screenshot.
Claude Code adds dynamic workflows (research preview) for large parallel agent runs
Dynamic workflows in Claude Code let Claude write orchestration scripts, fan out work across tens to hundreds of parallel subagents, verify results, and resume long-running jobs.
Claude Opus 4.8 Fast Mode: 2.5x Faster Output Tokens in Research Preview
Anthropic launched Fast mode for Claude Opus 4.8 in research preview, promising 2.5x faster output token speeds with the same Opus-level intelligence. It is available now in Claude Code for developers with extra usage enabled, and on the Claude Platform API through an account manager or a waitlist form.
Claude Code ships a security-guidance plugin for in-session vulnerability checks
Anthropic shipped an official security-guidance plugin for Claude Code. It runs automatic vulnerability checks while Claude edits files, at the end of each turn, and when Claude runs commits or pushes through its Bash tool.
Claude Agent SDK Monthly Credit on Paid Plans: Announced for June 15, 2026, Then Paused
As of August 2026, the Claude Agent SDK monthly credit is not available: Anthropic paused the change on June 15, 2026, and Agent SDK, `claude -p`, and third-party app usage still draw from your subscription's usage limits. The May 26 announcement had promised Pro, Max, Team, and Enterprise plans $20 to $200 per month from June 15.
Claude Code 2.1.142: `claude agents` Gains Session Flags, Fast Mode Defaults to Opus 4.7, MCP Tool Timeout Honored
Claude Code 2.1.142 (May 14, 2026) added eight dispatch flags to `claude agents`, moved fast mode's default from Opus 4.6 to Opus 4.7, and made `MCP_TOOL_TIMEOUT` raise the 60-second per-request cap on remote MCP servers. As of September 2026 the flags and the timeout fix stand, but fast mode has left Opus 4.7: the default moved to Opus 4.8 in 2.1.154 and to Opus 5 in 2.1.219, and the 4.6 override variable is a no-op.
Claude Code +50% Weekly Limits Promo Ended September 13, 2026; Limits Are Now 25% Higher Permanently
Anthropic's +50% Claude Code weekly-limits promotion ended September 13, 2026 at 11:59 PM PT. On September 14 Anthropic rewrote its support article: starting September 14, 2026, weekly limits in Claude Code are 25% higher than they were before the promotion for Pro, Max, Team, and seat-based Enterprise plans. Five-hour limits are unchanged.
Claude Code 2.1.133: `worktree.baseRef` Default Returns to `origin/<default>`, MCP OAuth Proxy Honored Across the Whole Flow
Anthropic shipped Claude Code 2.1.133 on May 7, 2026. The headline is a worktree-base behavior change: a new `worktree.baseRef` setting (`fresh` | `head`) defaults to `fresh`, which moves `EnterWorktree`'s base back to `origin/<default>` after three days of branching from local `HEAD` (since 2.1.128 on May 4). The release also routes `HTTP(S)_PROXY` / `NO_PROXY` / mTLS through the entire MCP OAuth flow (discovery, dynamic client registration, token exchange, refresh), exposes effort level to hooks via `$CLAUDE_EFFORT`, adds Linux sandbox path overrides, and fixes a refresh-token race that was 401-ing parallel sessions.
Anthropic's Claude Code Post-Mortem: Three Engineering Missteps Behind the Spring 2026 Quality Decline
Anthropic published a post-mortem on April 23, 2026 explaining the Claude Code quality regression that ran from early March through mid-April: a March 4 default-effort downgrade from high to medium, a March 26 caching change that wiped reasoning history every turn, and an April 16 verbosity prompt that capped responses at 25 words between tool calls. All three were resolved by April 20, the API was unaffected, and Anthropic reset usage limits for all subscribers.
Claude Code Subagent Patterns: 10 Reusable Agent Definitions
A Claude Code subagent is a delegated worker with its own context window, defined as a markdown file with YAML frontmatter in .claude/agents/. Subagents can edit files when you grant Edit or Write, nest three layers deep by default, and run 20 at a time. These 10 definitions cover the highest-value delegations.
Claude Opus 4.7 Best Practices: How to Actually Get the Most Out of the Upgrade
Claude Opus 4.7 follows instructions more literally than 4.6, runs longer agentic tasks more reliably, and ships a new xhigh effort level. Anthropic's launch-day guidance is to specify the task up front, batch your interactions, use auto mode, and default to xhigh; this guide adds the verification, recap, and scoping habits that make those gains show up in your sessions.
Codex CLI vs Claude Code vs Cursor: 2026 Architecture Deep-Dive (Sandboxing, Context, Plugins, Scheduling)
Codex CLI, Claude Code, and Cursor all reach for the same outcome -- an AI agent that ships code -- with three different architectures. Codex enforces safety at the OS kernel layer. Claude Code uses application-layer hooks for programmable governance. Cursor builds the agent into a visual IDE with a marketplace of plugins. The right one depends less on which model you prefer and more on which architecture matches your security posture, your composition needs, and your team shape.
Claude Opus 4.7 Is Here: State-of-the-Art Coding, xhigh Effort, and a New Cyber Safeguards Tier
Anthropic launched Claude Opus 4.7 on April 16, 2026 -- a notable improvement on Opus 4.6 in advanced software engineering, with the same pricing, a new xhigh effort level, /ultrareview in Claude Code, higher-resolution vision, and the first deployment of cyber safeguards from the Mythos Preview track.
Master Claude Code's 1M Context Window: Rewind, Compact, Clear, and Subagents
Claude Code's 1M token context window opens longer autonomous sessions but introduces 'context rot' -- degraded performance as the window fills. Master four turn-end tools: /rewind to drop bad branches, /compact to summarize and continue, /clear to start fresh with a distilled brief, and subagents to wall off noisy work in their own context.
Inside Claude Code's Rebuilt Desktop: Parallel Agents, Drag-Drop Panes, Side Chat
Anthropic rebuilt the Claude Code desktop app on April 14, 2026 around parallel agent workflows: a multi-session sidebar, drag-and-drop panes, an in-app file editor, integrated terminal, side chat, three view modes, and SSH on macOS. Four months on the app also creates routines and local scheduled tasks, browses external sites, and controls your computer.
Claude Code Routines: Schedule, API, and GitHub-Trigger Your AI Agents
Claude Code Routines is Anthropic's new way to run saved Claude Code configurations automatically -- by schedule, API call, or GitHub event. Routines run on Anthropic's cloud infrastructure with a prompt, repo, and MCP connectors. Available in research preview on Pro, Max, Team, and Enterprise plans.
Scheduled AI Coding Agents in 2026: Claude Code Routines vs Cursor Automations vs Codex vs Warp vs Gemini CLI
Five AI coding platforms schedule and trigger agents differently. Claude Code Routines and Cursor Automations ship schedules, API calls, and native source-control events; Cursor's trigger set is widest. OpenAI's ChatGPT scheduled tasks add Gmail, Slack, and GitHub pull-request event triggers on web and mobile, but no API or webhook trigger. Warp orchestrates other vendors' agents. Gemini CLI ships no scheduler.
Cursor vs Claude Code in 2026: Which AI Coding Tool Is Better?
Neither tool is terminal-only or editor-only any more. Cursor ships a CLI and Claude Code ships a desktop app, an IDE extension, and a browser surface. Choose Cursor for inline tab autocomplete and cross-lab model choice; choose Claude Code for one agent that follows you across surfaces.
