Anthropic's agentic coding tool, which runs in the terminal and the IDE. It is the agent most directly comparable to OpenAI's Codex, and the two are usually assessed against each other.
Claude Code was recorded in 81 items across 8 of the 8 briefings in the current window. That makes it the 3rd most covered.
Its share of coverage was steady: 26 items in the first half of the window and 55 in the second, tracking the feed as a whole, which grew about 2.2×.
It appeared most often alongside Codex, Claude and Cursor.
Working on exactly this! Check out Agent Skills API and other things we launched lately on @NotionHQ

I need agent portability... > My weekend project is to centralize all my skills, plugins, and keys, so that it's seamless to switch from one agent platform to another. (Codex, GrokBot, Claude Code, Muse, and more). > I will be testing all the platforms that allow you to do that this weekend, and that is the one I'll use for my business. > Will make video on this next week.
here is why Jev is essential for any harness you might be using → three question types: choice, score, and a yes/no called noul → ModelRouterMiddleware: Jev picks the least costly model that can do the step → AutoModeMiddleware: Jev scores every bash call before it runs and blocks the risky ones → the same trick Claude Code and Codex run with private classifiers, now a pip install → 200x faster and 400x cheaper than an LLM on classification their own line: "Agents are still inherently untrustworthy." so they put a second model in the loop whose only job is to judge the first one, in milliseconds.if this scales, every harness ships with reflexes.

Most people will use Jev wrong They'll try to replace their main model with it That's not where the value is Jev makes more sense for the tiny decisions inside your agent that happen hundreds of times Those tasks don't need Claude, GPT or another frontier model every single time Setup is simple: Get access at : Install the TypeSafe skill npx skills add typesafe-ai/skills --skill typesafe-ai For Claude Code: claude plugin marketplace add typesafe-ai/skills claude plugin install typesafe@typesafe-ai create your API key Ask your agent to use the TypeSafe skill From there, start replacing basic decision calls with Jev The biggest improvement comes when you use it across the whole agent flow: router → pick gate → validate judge → check result You can also batch many decisions into one request and send uncertain cases back to a larger model. That's the real use case: not replacing intelligence, but removing expensive intelligence from places where you never needed it > [@shann

A significant benefit is the ability to compare different agents and models when performing the same task. While performance is important, cost is also a crucial factor. Identifying a model that achieves the desired outcome at a considerably lower price point provides the kind of adaptability required by users of artificial intelligence.

Composio CTO @KaranVaidya6 says giving an AI agent your API key is basically making it public once prompt injection enters the picture: "Even if you use [MCP], across all your apps you have to go and authenticate one after the other. If you use Codex, if you switch to ChatGPT, Claude Code, you'll have to do it all over again." "In some cases where MCPs don't exist, you have to literally share the API keys to the agent, which is definitely not secure. It's kind of giving your API key to public." "At some point the agent will find some link which will have prompt injection, and you'll be in a bad place where your key is gone and all your data is public." "We launched Shared Connections where you can share, let's say, an analytic software across the team, or DataDog for debugging, so you don't have to share one password or API keys to every single person." @composio
Union Alpha is GLM-5.5 I spent hours studying this model the text tokenizer has been specifically modified - that’s actually how Ox Alpha was identified but there is a vision tokenizer, and it matches the GLM-5.3 Flash and the GLM-5.5 was planned for release in September-October if other than the GLM-5.5, then it's DeepSeek or Qwen very strong model

AI agents can generate amazing research, reports, and websites — but the final output often gets buried inside chats or `.md` files. That’s where Showly comes in. 👇 Ask your agent to deliver the finished work as a page — Showly gives you a link people can open and share It works with tools you already use, including Claude Code, Codex, Cursor, OpenClaw, Hermes, and more. You can also control who gets access with private reviews, password protection, domain/email rules, and full version history. I especially like the idea of going from: Agent → finished work → page with a link → shareable deliverable If you're building with AI agents and want a better way to present the work they produce, check out Showly: 👉
We open sourced BrowserSkill, a bridge between your agent and your actual browser. most tools give the agent a blank browser. We let it borrow a tab from yours, then hand it back. > login state is already there, it just works where you're signed in > captchas and confirmation dialogs come back to you, then it continues > it's a CLI, not an MCP server => any agent that can run a shell can use it, and you see every call it makes one thing that's easy to miss: the agent asks before borrowing a tab, and that switch lives in your browser settings, not in a flag, so it can't be talked around. one line to install, works with Cursor, Claude Code, Codex, Hermes, Openclaw, CodeBuddy, WorkBuddy. Everything runs locally, MIT.
Sightless is here. You can now use your voice to use your entire iPhone or iPad — every app, setting, tap, swipe, touch, and keystroke — without Siri’s restrictions, both on Wi-Fi and cellular. Voice works via your existing ChatGPT plan. Sightless also works with any AI model or agent that you already have on your computer. Just message your existing Grok Bot, Codex, OpenClaw, Claude Code or Codex agent and tell it to use the macOS app to operate your iPhone or iPad! Anything you do on an iPad or iPhone, you can now do via voice or by messaging your existing AI agents and telling them to use Sightless. On Wi-Fi or cellular. Handsfree. Not just simple requests either. It can work across all of your apps for long, chained, complex work, and talk to you while it does it. And you can jump back in and steer it or stop it with your voice or hands whenever you want — it never locks you out. Get it at today.
Anthropic Claude Opus 5.2 is live in testing and they skipped 5.1. - Opus 5.2 leaks: Beats Fable 5.1 - Opus 5.2 is already being tested inside Claude Code. - The slug “claude-opus-5-2” showed up in Microsoft Foundry. - Some live traffic is already being routed to it. - Reports say it beats Fable 5.1 and is a real leap over Opus 5.

Someone built an open-source version of GrokBot that runs on the Claude Code/Codex subscription you’re already paying for. Same basic idea: Give your agents access to a computer. Connect their apps through Composio. Run them through the AI subscription you already have. But OpenMausBot itself is free and open source. You can run the agents locally, connect them to your own computer, or give them a cloud computer through an optional third-party service. Very worth knowing about if you already pay for Claude Code or Codex.

Multi-agent systems usually hide the coordination layer inside an orchestrator. @Plasma__AI Plasma AI launched Radio, and puts that coordination in a room you can actually watch. Radio is a shared chat room where agents from different providers can talk directly. Without a shared channel, each agent sees only its own conversation, leaving humans to relay outputs between separate tools. Radio replaces that handoff with a link, and Plasma says any agent that can fetch a URL can join, including Claude Code, Codex, Cursor, OpenCode, and Grok.
