Anthropic Launches Claude Duet, a Proactive Agent in Research Preview

Oct 21: standalone Claude agent that watches connected apps, pushes a morning brief, and nudges every few hours. Built on Opus 5.5.
Research preview for US Pro and Max subscribers via waitlist; dedicated iOS and Android apps plus claude.ai web.
Requires explicit human approval for actions like sending messages, payments, signing, or deletion; securities trading and fund transfers are hard-blocked.
Internal name was 'Claude Loop'; positioned against Meta Muse and OpenAI Dots. Shares the same usage quota as standard Claude.

Politico scoop Oct 16: Anthropic quietly circulated draft federal legislation after the Thune-Cruz-Klobuchar effort stalled, confirmed on-record by a spokesperson.
Trigger: 'foreseeable, imminent' risk of over $1B in damages or more than 50 deaths or serious injuries.
Scoped to three scenarios — bioweapon abuse, AI-enabled cyberattack, or a model evading its developer's controls.
Only the Commerce Department would have standing; it must petition the DC District Court, and no other agency gets suspension power. Bill has not yet been introduced.

stablyai/orca at 101.7k stars, MIT — self-styled 'AI orchestrator for 100x builders.'
Runs Claude Code, Codex, OpenCode, Pi, Grok, and Cursor in parallel across per-agent git worktrees.
Mobile companion app, embedded Chromium Design Mode, SSH worktrees, GitHub and Linear integration.
Free with BYO agent subscriptions; from Stably AI (YC W22). One of this week's clearest coding-agent breakouts.

morluto/rea now at 359.8k stars after a roughly 60k weekly jump — MCP server plus CLI for agentic reverse engineering.
Covers native binaries via Hopper, Ghidra, and IDA, plus Electron apps, .NET, APKs, websites, firmware, and packet captures.
`npx rea-agents setup` wires it into Claude Code, Codex, or Cursor as installable skills.
MIT license. One of the week's loudest GitHub trending breakouts and a notable shift in what coding agents are being pointed at.

heygen-com/hyperframes at 69.4k stars, Apache 2.0 — 'Write HTML. Render video. Built for agents.'
Turns HTML, CSS, animations, and media into deterministic MP4 via headless Chrome plus FFmpeg.
Runs as a local CLI, as an agent skill inside Claude Code or Codex, or as the rendering core for hosted tools.
HeyGen's open-sourced bet that agents will author video the same way they already author code and slides.

K-Dense-AI/scientific-agent-skills at 53.7k stars, MIT — pitched as 'turn any AI agent into an AI Scientist.'
Covers biology, chemistry, medicine, physics, engineering, earth science, data, and sci-comm.
Follows the open Agent Skills standard that works across Cursor, Claude Code, and Codex.
Python-first (3.13+, uv, pytest). Another sign that domain skill packs are becoming the layer agents compete on.
