Claude can now be added to Slack group DMs just like any other member. It responds in threads, keeps following them so anyone in the DM can continue the conversation, and can use the personal connectors of whoever is asking.
Trq212 names the cloud-plus-local-folder pattern "local hands": Claude runs in the cloud but reaches down to access files on your machine. The pattern is also coming to the cowork feature.
Cloud sessions spin up a fresh VM per task, run in the background after you close your laptop, and can be started in parallel. A new field guide covers seven workflows suited to this setup, plus first-try GitHub connection instructions.
Project sessions can now live in the cloud while still connecting one-off to a local folder when needed, combining cloud persistence with local file access.
The prompt used to build the Acquired FM Home Depot episode companion site with Opus 5.5 is now linked publicly in the thread.
Bcherny used Opus 5.5 to generate a full interactive website companion for an Acquired FM episode on Home Depot. The site includes watercolor illustrations drawn entirely by Claude.
Following up on his earlier post about using Opus 5.5 to formally verify the Claude Agent SDK with Lean, bcherny shared the actual prompts he used, giving a concrete look at his workflow.
Pro and Max plan members who were active on September 23 can claim a one-time bonus credit by running /claim-credit in Claude Code before October 7 at 11:59pm PT. Cloud sessions draw from this credit first, then from regular plan limits once the bonus runs out or expires November 4.
When building the Acquired FM companion site, Claude chose on its own to read the episode transcript plus additional primary sources, without being explicitly told to. The full prompt is linked in the thread.
The prompt used to generate the interactive Acquired FM companion site with Opus 5.5, including the watercolor illustration instructions, is now posted publicly.
Bcherny argues that elaborate prompt engineering is largely obsolete with modern models. The key things to communicate are what you want done, how much effort to spend, and how the model should verify success. Back in the Sonnet 3.5 era, prompt structure mattered more; now the model figures out the rest.
The HTML planning skill in Claude Code avoids regenerating common components like state machines, diagrams, and code snippets, making it significantly more token efficient than producing raw HTML from scratch each time.
A user worried about losing local threads/tasks mode in Cowork gets confirmation that local files and apps still work the same way. Claude Code is offered as an alternative for tasks that genuinely need to run locally.
Dfeinition describes running multiple parallel cloud threads across projects, steering them from a phone with the laptop closed. The local folder connection reduces friction for the occasional thread that needs to access something on the local machine.
The key advantage of running Claude in the cloud rather than locally is persistence: work continues even after you shut down your computer, confirmed by trq212.
Cloud sessions in Claude Projects carry no additional cost beyond the existing subscription, confirmed by trq212 in response to a user asking about pricing.
The CoWork product mounts files over a network rather than running them in a remote sandbox. Other remote products in Anthropic's lineup do support sandboxes.
