"summary": "Anthropic’s ‘What are projects?’ help page now says it has started moving existing projects for some Pro and Max users to the redesigned version, where a project is one conversation that splits work into parallel cloud threads. Instructions, files, full chat history and scheduled tasks all carry over, and anyone who used a project in the last 30 days gets an email first.",
"body": [
"The line went onto the help page on 14 Oct, and MACCUS’s write-up (updated 18 Oct) was the first to spell out what it means. A second brain built as an old-style Project, a binder of chats plus a knowledge base and standing instructions, becomes a single conversation. A coordinator breaks each request into threads that keep running after you close the laptop, every thread starts with the project’s files, instructions and memory, and a Library collects what you add and what Claude produces.",
"Anthropic says ‘nothing is lost or deleted in the move’. Other chat and Cowork projects stay on the current version for now, and Team and Enterprise follow with no date. Neither the help page nor the docs says whether you can opt out or switch back, and the Claude Code docs, also updated 14 Oct, still describe a rollout limited to accounts with no existing projects.",
"What to do before your email arrives: tighten your project instructions so each thread starts with the right rules, prune the knowledge base so every thread isn’t loading stale files, and keep a copy of anything you can’t afford to lose outside Claude, for example in a Git repo or an Obsidian vault. Running several threads at once also uses your plan’s allowance faster."

Within three days at least five near-identical threads followed.",
"body": [
"The recipe is the same in every version: one folder on your own disk, Claude Code started inside it, and a short CLAUDE.md that tells the agent where things live. @ottollm’s 15 Oct take puts it at about 20 minutes. @0xCortexq and @Frelzu’s variants drop Obsidian and Notion altogether: notes/ for facts, people/ for contacts, projects/ for status, one Markdown file per topic, named for what’s inside.",
"The new part is the Google Workspace CLI step, which gives the agent your inbox, calendar and Drive. That is what makes the folder ‘know your life’, and it is also the risk. Before copying it, give the CLI the narrowest scopes it will accept, keep send and delete behind a permission prompt (an ask rule in .claude/settings.json), and commit the folder to git so you can see exactly which notes Claude changed."

The Projects guide, revised 10 Oct, adds the practical limits that matter for a second brain: uploaded folders are copies (first 100 files, 200 MB) that don’t sync, and a project with several repos on Anthropic’s hosted environment applies no repository’s permission rules.",
"body": [
"The redesigned Claude Projects, where one coordinating conversation hands work to parallel cloud threads that share instructions and a MEMORY.md-indexed project memory, is no longer a select beta. On 9 October the Claude Code team said it had let in every Pro and Max user from the waitlist, with a four-minute walkthrough attached. The post drew more than 15,000 likes and 15,000 bookmarks, by far the most-saved Claude memory post this edition. The waitlist stays open for everyone else, and Team and Enterprise still have no date.",
"For second-brain builders the useful detail is in Anthropic’s Projects guide, revised on 10 October. Files and folders you add are copies. A folder brings in its first 100 files up to 200 MB, skipping hidden files and anything over 30 MB, and a project holds up to 10 folders and Google Drive folders. A note you edit on your laptop afterwards doesn’t reach the project until you upload it again and choose Replace. A living vault is better kept in a GitHub repo, which every cloud thread clones fresh along with its CLAUDE.md and skills.",
"Two more rules worth knowing. In a project with one repository, cloud threads apply that repo’s .claude/settings.json permission rules. With several repositories on Anthropic’s hosted environment, no repository’s rules apply, so standing limits belong in project instructions (up to 16,000 characters). And a new project runs every thread on Opus at high effort, which uses up a Pro plan fastest. Check Thread model and effort in Project settings › General before you send the first batch, and tell Claude to remember corrections so later threads start with them."

"For second-brain builders the key change is where the notes live. Projects are no longer a folder on your computer; a folder is now one kind of context alongside uploads and synced sources. Moving a folder to the cloud is a one-time snapshot that stops updating, so Gray’s advice is to keep a living knowledge graph either linked from the desktop app or in a synced GitHub repository or Google Drive, which any device can refresh with one click.",
"Memory is now a single store read and written by both chats and cloud tasks, saved as editable topics in Settings › Memory, with each Project keeping its own separate memory. A new ‘include sensitive topics’ switch is off by default, and four categories (government IDs, criminal history, financial account numbers, immigration status) are never saved."

Project instructions, up to 16,000 characters, are the standing brief sent to every new thread. And each repository’s own CLAUDE.md and skills still load from every clone.
