Musk throttles Grok Bot limits over 'unsustainably high' costs

Paying Grok Bot users saw weekly usage meters jump to 100% overnight, some from as low as 50%, days before reset. Musk said serving the agent cost too much relative to revenue; a Cursor staffer called the spike a fault that "shouldn't happen."

Subvocal adds radar-based silent dictation at 200+ wpm

Backdoored Claude Code extension hit up to 5,000 Cursor users

A malicious version of Anthropic's Claude Code VS Code extension (2.1.313, later 2.1.312) was posted to Anthropic's official Cursor Marketplace account for roughly 11 hours, attempting to install a persistent SSH backdoor. Cursor says at most 5,000 users were affected; Ars reports Anthropic had not yet notified customers.

Cursor adds Computer Use to operate other laptop apps

Jellyfish data: swapping coding models barely moved merged PRs

Jellyfish's Nicholas Arcolano analyzed data from ~50,000 engineers at 447 companies; when Cursor pushed many users onto Grok, merged PRs barely moved. A separate Jellyfish talk reports AI spending up 60x while allocated cost per merged pull request fell.

Tool turns plain-English prompts into HTML and SVG diagrams

Tool manages coding agent skills across Claude Code, Cursor, Codex, Windsurf, Amp

Sonar pitches verification loops as AI coding gains fade

A Carnegie Mellon study of public repos adopting Cursor found a three- to five-fold increase in lines added in the first month, with gains dissipating after roughly two months. Sonar argues verification tooling sustains the productivity.

Cursor releases Agent SDK for defining and deploying agents as code

Agents are defined as a folder of code — instructions.md for the prompt, TypeScript tools, skills, MCP connections and channels — then deployed with `agent-sdk deploy` to Cursor infrastructure or your own. Built-in evals and `agent-sdk github replay <pr-url>` test bots against real pull requests.

Meta's Muse Wonder coding model rolls out to Cursor, Cline, Cloudflare and Vercel

Beacon saves AI coding sessions across Claude Code, Cursor, Codex

AI coding tools make code free, and features worthless

Teams using Claude Code, Cursor, or Copilot to produce more code face a paradox: when output is free, selling volume stops being a viable strategy. The piece argues AI-accelerated development may cost teams the thing that makes their software valuable.

Talk: agent harnesses matter more as models get smarter

Jediah Katz, described as Cursor's longest-tenured agent-harness engineer and now at SpaceX, argues fancy harnesses no longer add coding intelligence because the data flywheel teaches models the skills harnesses once patched in. He then argues the harness matters more than ever.

Sphinx is a Git hook that quizzes you on AI-written code before push

Sphinx pauses protected branches and asks a reviewer model questions about what the diff does when things go wrong; wrong answers explain why and prompt a retry. Installs via npm (Node 22.19+, macOS/Linux/WSL) and works with Codex, Claude Code, Cursor, OpenCode, and Pi.

Navan cuts Spring Boot 4 migration to a week with Cursor Cloud Agents

Navan moved 8 applications and 15 libraries to Spring Boot 4 in about a week, versus over a month for a comparable migration two years ago. Cloud Agents ran in parallel on Navan's self-hosted machines, spinning up browsers to verify flows.

Cursor cloud agents build shareable interactive canvases

Cursor's cloud agents can now produce interactive canvases that are shared via link, alongside a beta Environments API for programmatically creating and managing agent environments. Environments now support up to 300 repositories, with large environments loading 5x faster.

Cursor's Bot gets faster in latest update

Cursor's Origin App Marketplace opens to public submissions

Origin integrates over 20 apps spanning deployments, CI, code review, security, monitoring, and project management, with partners including Cloudflare, Linear, Sentry, and Socket Security. Apps authenticate via app JWT and installation access tokens, and can write back check runs, PR comments, and reviews.

SpaceXSI bundles X Premium, Grok and Cursor into one subscription

The X Subscription has five tiers: free, Plus ($8/month), Premium ($30/month), Super ($100/month), and Ultra ($200/month), with AI usage caps rising by tier. Premium or higher is required for the latest Grok models, and Claude now costs extra.

Pensieve indexes files and agent sessions locally to cut tool calls

Pensieve connects over MCP to Claude Code, Codex, Cursor, Gemini CLI, Windsurf and VS Code, returning matching passages with file and line instead of grepping the disk. In its benchmark, agents averaged 2.0 tool calls per lookup versus 3.4 with grep, answering in a single call in 82 of 144 runs.

Claude-built Mars tower defense game approved for Apple iOS store

A Reddit user built a Mars tower defense game entirely with Claude via Cursor — artwork, code, and marketing material — over about a month of prompting and testing. The game was approved for the Apple iOS store.

Grok Bot update adds dedicated email addresses and Cursor integration

Agent.reviews launches as a review site written by AI agents

Armature (YC P26) built agent.reviews after measuring 50k+ agent sessions where coding agents hit the same tool limitations repeatedly. Agents read reviews via skill.md and can post their own; every page has a Markdown version at its address plus .md.

Cursor adds iOS remote control for local agents

Cursor's iOS app now lets users view and message local agents running on their desktop, with agents staying on the machine rather than moving to the cloud. Remote Control is on by default except for Enterprise orgs, and the computer must stay on, online, plugged in, and lid-open.
