Daily Agent News, Tuesday, 3 November 2026

Good afternoon. Today's lead: coding agents now push so much code at OpenAI that it had to rebuild the system behind Git for its main repository, and agents did most of the building. Also today: Goldman Sachs takes Claude Code away from its traders and bankers, Coinbase opens a front door for trading agents, Shopify's boss says structured store tools beat browser-driving agents, one investor's agent swarm flags $787 million of strange government billing, a personal agent wins a $700 flight-delay payout, and an open-source copy of Claude Duet passes 6,600 GitHub stars.

LEAD: Agents write so much code that OpenAI rebuilt Git's back end

Background: Git is the system almost every software team uses to track code changes. A normal Git server lines up every update to a repository in a single queue, which is fine for people but starts to choke when hundreds of agents push work at once.

What happened: On 2 November OpenAI engineers Aaron Friel, Taylor Blau and Ted Nyman published Scaling Git at OpenAI, describing Pando, a new Git-compatible back end that now runs all development in OpenAI's main repository (its "monorepo"). The reason is agents: Codex lets engineers run many changes in parallel, and every push sets off test jobs that fetch the same code. The New Stack reports OpenAI expects quarterly commits to that repository to be up more than 2,400% on early 2024 by the end of this year.

Pando handles each branch separately, so pushes to unrelated branches no longer wait on each other, and it reuses the same compressed bundles of code for many downloads instead of building a fresh one for every client. OpenAI says median push time fell almost fivefold and Pando now serves nearly a petabyte of Git data a day. The vivid part is how it was built: from kick-off to production in 10 weeks, with the core "designed by a single engineer, implemented by teams of agents, and deployed by a handful of engineers". Agents running GPT-6 Astra also wrote formal maths specifications of the system (in Lean and TLA+), which were used to hunt for bugs. It has served live traffic since April.

Why it matters: This is one of the clearest signs yet that agent output is straining the plumbing of software teams, not just their review queues. OpenAI chose to keep Git working as normal for both people and agents rather than move to something new.

Goldman Sachs takes Claude Code away from traders and bankers

Background: Earlier this year Goldman cheered on "vibe coding" outside its tech teams. In July its chief information officer, Marco Argenti, described bankers and traders building their own tools with AI and handing them to one of the bank's 12,000 engineers to polish.

What happened: Bloomberg reports that internal guidance updated in October now limits Anthropic's Claude Code and Microsoft's GitHub coding tools to engineers. Most traders and bankers have lost access, which has frustrated some who used the tools to monitor client trading flows, model positions and make text and charts. "Strats", who mix software engineering, quant research and trading, are exempt. A Goldman spokesperson said tools go to "those who are best suited to leverage them for the long term" after weighing productivity and risk (Quartz). Goldman also has its own in-house AI assistant, which draws on models from OpenAI, Anthropic and Google, and it restricted Claude for Hong Kong staff earlier this year.

Why it matters: It's a high-profile reversal of the idea that every knowledge worker should get a coding agent. Expect other banks and regulated firms to draw similar lines between people who can review what an agent built and people who can't.

Coinbase opens a sign-up page just for AI agents

Background: Coinbase launched "Coinbase for Agents" in June, letting agents trade through a customer's account within limits.

What happened: On 2 November chief executive Brian Armstrong posted a new sign-up page for agents, saying "We're building Coinbase to be the most AI-enabled financial account" (via TokenPost). Coinbase's developer docs show agents connect through an MCP server at agents.coinbase.com, signing in with the user's Coinbase account, and list spot crypto trading, portfolio management and x402 payments, so an agent can pay for trading data and research from the account's USDC balance. Setup is a one-line prompt: "Set up coinbase.com/skill.md". Coinbase tells users to create a separate portfolio for the agent, "fund it with only what you're willing to risk", to limit "the blast radius if the agent makes an unexpected trade".

Why it matters: A major regulated exchange is now courting agents as customers. The sensible default it suggests, a ring-fenced pot of money, is a useful pattern for anyone letting an agent near real funds.

Shopify's boss: structured store tools beat browser-driving agents

Background: Most shopping agents still "browser-use": they read a page's code and click buttons like a person, which is slow and breaks easily. WebMCP is a proposed web standard that lets a page hand an agent a list of proper tools instead.

What happened: Shopify re-promoted its WebMCP tools, and Tobi Lütke added: "Webmcp is so much better then browseruse" (Lütke on X, quoting ShopifyDevs). Per Shopify's docs, every Liquid storefront (and Hydrogen sites on the October 2026 release) exposes tools such as search_catalog, update_cart and proceed_to_checkout, with checkout registering its own tools when the shopper gets there. Everything happens in the shopper's own open tab, and Shopify warns agents to treat shop text as data, not instructions, because of prompt injection. The catch: agent support is still limited to Chromium browsers.

Why it matters: Every Shopify store on Liquid quietly became agent-readable with nothing to install. If WebMCP takes off, shopping agents get faster and fail less, and sites that don't offer tools may simply be skipped.

One investor's agent swarm flags $787 million in billing that "made no sense"

What happened: Entrepreneur and investor Matt Mickiewicz posted a thread saying that over 10 days his "AI agent swarm", working through public and private records, found about $787 million in US government billing that "made absolutely no sense". One example he gives: more than 100,000 nursing-home residents a year enrolled in chronic-care management under a doctor who never saw them. He says he checked every case against Justice Department records, court dockets, company filings and the federal exclusion list before filing 37 tips with evidence packets, and that most of the people and companies have no public charges. Asked what it cost, he replied "couple hundred bucks, thanks to the subsidized agents."

Why it matters: The thread passed 850,000 views and shows how cheap large-scale data sleuthing has become. These are one person's claims, not findings of fraud, and nothing has been charged.

A personal agent wins a $700 flight-delay payout, then trips over its own outage

What happened: Investor Deedy Das posted that "Instinct just made me $700". He texted the personal agent Instinct after a six-hour delay on a flight from Europe; it told him EU law entitled him to €600, then handled "many esoteric email exchanges" until the money arrived a month later. Separately, Instinct stopped answering on WhatsApp on Monday, and some users thought Meta had blocked it. Founder Noah Shinn said a configuration problem on Instinct's side had interrupted payments to a service provider, and that service is back (Digit). Reports of some users' WhatsApp accounts being banned remain unexplained.

Why it matters: Patient, month-long chores like compensation claims are where personal agents shine. But agents that live inside someone else's messaging app depend on that platform and their own back office, and a single missed payment can take them offline.

Open Duet: a free, self-hosted take on Claude Duet passes 6,600 stars

What happened: Open Duet, an Apache-2.0 open-source project, lets people run a team of named AI "coworkers" on their own machine, each with instructions, memory, scheduled routines, its own isolated computer, and your approval before acting. A lead agent running Claude or Codex can hand work to specialists. It had about 6,660 GitHub stars when checked today. Anthropic's own Claude Duet is still a US-only research preview with a waitlist.

Why it matters: The "team of agents with their own computers" design is being copied in the open within weeks, which means the product, not the idea, is what the big labs will have to win on.
