Anthropic changed how Claude Code runs big jobs on Nov. 13. Its ClaudeDevs account posted the update at 10:51 p.m. UTC: "The coordinator is now much more proactive. It answers your questions in the project chat and gives you updates on the status of your ongoing threads"1. By Saturday, the post had drawn 17,211 favorites and 585 replies.
ClaudeDevs@ClaudeDevsWe've made some big updates to Projects in Claude Code!

The update lands inside Projects, a feature that has run in beta since Sept. 173. A project is one long chat with Claude. Claude decides which parts of the work become their own threads. Each thread then runs as a full, separate Claude Code session, on its own branch of the code2.
Developers used to juggle this by hand. A five-job day meant five separate chats, each needing its own prompt and check-in3. Projects folds that switching into one long conversation, and lets a developer check progress from a phone while each session keeps running.
One Chat Now Runs the Whole Project
Every thread opens with the project's own files already loaded2. It inherits the repositories, the instructions, the shared memory and the account connectors Claude built up before. A thread skips the project's custom skills, and it skips any tool that only runs on a local machine. It can also open its own pull request when it finishes, a step a developer used to start by hand.
Remote Control lets a thread reach those local tools anyway, on the developer's own machine2. That takes a setting called "Require trusted devices" turned off, and Claude Code version 2.1.280 or newer.
Anthropic caps the whole system at 500 new threads a day, per account, across every project2. An early count that spread this week put that cap at 200. Reading Anthropic's own page, the one that count came from, shows 500. A second analysis published the next day checked the same figure and found 500 too4.
Team and Enterprise accounts stay outside the beta for now2.
The Proactive Coordinator Ships 57 Days After Projects Launches
Four dated events in Claude Code Projects' rollout, 2026
Each pin is one dated event in the rollout; the gap between Sept. 17 and Nov. 13 runs longer than the others, so the rail breaks there and marks the gap's length.

The numbers behind this chart
| Date | Event |
|---|---|
| Sept. 17, 2026 | Projects opens in beta |
| Oct. 8, 2026 | Engineer logs token cost. A software engineer logs the cost of coordinating multiple parallel Claude Code threads. |
| Nov. 13, 2026 | Update adds coordinator. Anthropic's Nov. 13 update makes the coordinator proactive across every running thread. |
| Nov. 14, 2026 | 500-thread cap confirmed |
Running several threads at once can burn through a plan's limit faster than one conversation would. The coordinator's own chat spends tokens too, on top of whatever its threads spend2.
The Bill Comes Due Fast
Dmitriy Fedoryshchev runs multi-agent Claude Code setups daily. He is a lead software engineer at Evercommerce, a company on the Nasdaq5. In October, weeks before this update, he wrote plainly about the cost.
"Two hours of this drains a full Max 5x quota, on a heavy day just in 90 minutes, and coordination is a real line item inside that," Fedoryshchev wrote5. That is 120 minutes for a typical run, and 90 for a heavy one.
Anthropic reached a similar finding on its own. Fedoryshchev cites Anthropic's own review of multi-agent teams. It found they "suffered from lost context at each handoff and spent more tokens coordinating than executing"5.
Fedoryshchev still backs the design. He argues the cost buys something real. "The handoff isn't a bug in the design, it's the price of the boundary, and the boundary is the whole reason those roles exist," he wrote5.
A Heavy Day Cuts Claude's Quota Window From 120 to 90 Minutes

| Item | Typical parallel run | Heavy day |
|---|---|---|
| Minutes to drain a day's quota | 120 min | 90 min |
A single Max 5x seat already strains under five threads on some days. The Nov. 13 update adds a coordinator that starts more threads with less prompting, while the token bill stays the same.
The Product Lead Who Left First
Cat Wu led product for Claude Code at Anthropic. She joined in August 2024, when Claude Code was a small internal tool6. Her last day at Anthropic came in late October, and OpenAI announced her hire on Nov. 5.
Wu described how far the tool's autonomy had already moved before she left. "Today, the default is trusting Claude's judgment to auto-approve. Claude does large migrations and builds new products," she said6.
She left for OpenAI, to lead product for its Core Products team6. At OpenAI, she now reports to Thibault Sottiaux on that team. The coordinator update then shipped on Nov. 13, about two weeks after she left. It builds on exactly the autonomy Wu described1.
Configure It, Critics Say
Yash Thakker reviewed the update the day after it shipped4. He confirmed the same daily cap of 500 new threads. His advice to readers was direct. "Treat proactive updates as a feature you configure, not a default you must accept," Thakker wrote.
Thakker pointed to Anthropic's own warning on the feature. The company's documentation, he wrote, says "parallelism is easy; spend control is on you"4. A developer gets threads started automatically now. Watching what they cost still falls on that same developer.
What to do
Count your threads before you turn the coordinator loose. Five threads running at once spend five sessions' worth of tokens, on top of the coordinator's own chat2. Ask it for a running total before you close your laptop, since threads keep working after you leave.
Set a cap inside the project's own instructions, the way Thakker suggests, in place of the default4. Tell the coordinator to post only when a thread stalls. Watch your plan's usage page the first week you try it.
By the numbers
- 500: new Claude Code Projects threads one account may start a day, confirmed Nov. 14, 20262.
- 17,211: favorites on Anthropic's Nov. 13 announcement, as read Nov. 15, 20261.
- 585: replies under that same post, read the same day1.
- 90 minutes: how fast a heavy day of parallel threads can drain a Max 5x quota, one engineer's measured use5.
- Sept. 17, 2026: the date Claude Code Projects opened in beta3.
- August 2024: when Cat Wu joined Anthropic to build Claude Code's product6.
- Two weeks: the gap between Wu's departure and the coordinator update shipping16.
What to watch
Watch whether Anthropic names a new head of product for Claude Code in public6. A new name there could change how freely the coordinator spends. Your own plan's usage page is worth a look too, once the coordinator starts threads on its own2. The cap just rose, but the token bill stayed the same.
