Claude Code Desktop lets you ship inside one app

Claude Code Desktop turns chat, diffs, and terminal work into one session flow.

I've been using desktop AI tools long enough to know when something is trying too hard. Claude Code Desktop kept doing that. The pieces were all there: chat, file edits, a terminal, browser previews, even side sessions. But the workflow felt weird until I stopped treating it like a chatbot and started treating it like a workspace with rules. That was the missing mental model.

What finally clicked for me was the session boundary. One conversation is not “just a thread.” It has its own project folder, its own context, and its own changes. Once I started working that way, the app stopped feeling like a fancy prompt box and started feeling like a controlled dev surface. Still opinionated, still a little busy, but at least coherent.

The docs page that pushed me over the edge is the Claude Code Desktop application reference. It’s not a blog post or a launch announcement. It’s the actual reference for the Code tab, and that matters because the useful stuff is buried in how the app expects you to work: sessions, permission modes, preview panes, and environment choices. I’m focusing on that, not the marketing gloss.

Stop thinking in chats. Start thinking in sessions.

In the Code tab, each conversation is a session: it has its own chat history, project folder, and code changes, independent of any other session.

What this actually means is that Claude Code Desktop is trying to isolate work the same way I’d isolate branches or scratchpads. A session is not just a conversation log. It is a working container with state attached to it. That state includes the repo you pointed it at, the edits it made, and the context it has accumulated.

I ran into this immediately when I tried to use one conversation for “fix the bug,” “also update docs,” and “oh by the way, can you check this unrelated error.” The model kept dragging earlier context into later decisions. Once I split those into separate sessions, the quality improved fast. Less contamination, fewer accidental follow-ups, less “wait, why is it looking at that file?”

The docs make a point of saying the sidebar lists your sessions and lets you run several in parallel. That’s the real trick. I don’t want one giant thread that becomes a junk drawer. I want multiple bounded workspaces, each with a single intent.

How to apply it:

• Use one session per task, not one session per day.
• Keep each session tied to a single repo or folder unless you truly need cross-project context.
• When work starts drifting, stop and open a new session instead of forcing the old one to absorb everything.

That sounds obvious, but it’s the difference between “AI assistant” and “AI that slowly ruins your context.”

Pick the environment before you type anything

Before you send your first message, configure four things in the prompt area: Environment, Project folder, Model, Permission mode.

What this actually means is that Claude Code Desktop wants you to make the operational choices up front. I like that, even if it feels a little bossy. It prevents the classic mess where you ask the model to do work before you’ve told it where to run, what repo to touch, or how much freedom it has.

The environment choice is the one people will gloss over and then regret later. The docs call out Local, Cloud, SSH, and on Windows, WSL. That’s not just a deployment detail. It changes how the session behaves, what persists, and how long the work can continue after you close the app. Cloud sessions can continue after you close the app. SSH points at a remote machine you manage. WSL is there because Windows development is still Windows development.

I’ve made the mistake of starting a local session when I really wanted a cloud session for a long-running task. Then I closed the app, came back, and had to reconstruct the context. Annoying. The app is telling you to choose your execution surface first because the surface is part of the task.

How to apply it:

• Use Local when you want immediate access to your machine, files, and terminal.
• Use Cloud when the task may outlive your browser or desktop session.
• Use SSH when the repo lives on a remote box and you want the work done there.
• Use WSL on Windows if your tools and scripts expect a Linux-like environment.

Also, the install note matters more than it looks: on Linux, install with apt and see Claude Desktop on Linux. On Windows, the first launch needs Git for Windows installed, and then you restart the app. That is exactly the sort of dependency that wastes 20 minutes if you ignore it.

Permission modes are the whole point, not a side setting

Permission modes control how much autonomy Claude has during a session: whether it asks before editing files, running commands, or both.

What this actually means is that Claude Code Desktop is not pretending every task should be fully automated. It gives you a spectrum, from Manual to Accept edits to Plan to Auto to Bypass permissions. That spectrum is the product.

I appreciate the honesty here. Most tools act like autonomy is a binary: either the bot is helpful or it is dangerous. This app gives you a wider control surface. Manual means Claude asks before editing files or running commands. Accept edits means it can make file edits and common filesystem commands like mkdir, touch, and mv, but still asks before other terminal commands. Plan is for exploration and proposal without editing. Auto executes actions with background safety checks. Bypass permissions skips prompts except for the hard-coded exceptions the docs list.

The part I actually use most is Plan first, then Accept edits. That sequence keeps me from letting the model wander into implementation before I’ve agreed with the approach. The docs even call out that Plan is good for complex tasks where you want to review the approach first. Yes. Exactly. That’s the mode I want when the task is fuzzy and the repo is old enough to have opinions.

How to apply it:

• Use Plan when the request is broad, risky, or likely to touch several files.
• Use Accept edits when you trust the direction but still want command-level control.
• Use Manual for anything you’re nervous about, especially early in a repo.
• Use Bypass permissions only in sandboxes or VMs, exactly as the docs warn.

The docs also note that the selected mode is remembered per folder, which is the kind of small detail that saves a lot of repetitive friction. That means your repo can have a stable default behavior instead of making you reassert your preferences every time.

The prompt box is a control panel, not a chat bubble

The + button next to the prompt box gives you access to file attachments, skills, connectors, and plugins.

What this actually means is that the prompt area is where you assemble context, not just where you type requests. The app wants you to feed it files, screenshots, PDFs, and extra capabilities before it starts making decisions. That’s a much better model than “type a sentence and hope.”

I’ve had a lot of success when I stop narrating the problem and start attaching the evidence. Bug screenshot? Attach it. Design mockup? Attach it. Spec PDF? Attach it. The model can only work with what it can see, and the desktop app is built to make that visible context easy to add.

The docs also mention @mention files, where you type @ followed by a filename to add it to context. That’s handy in local sessions, but the docs say it’s not available in cloud or WSL sessions. That limitation matters. If you build a habit around @mentions without noticing the environment, you’ll think the feature is broken when it’s actually just unavailable in that mode.

How to apply it:

• Attach screenshots for UI bugs instead of describing them in prose.
• Attach spec docs when you want implementation to match a written requirement.
• Use @mentions in local sessions to keep context explicit and lightweight.
• Don’t assume the same attachment behavior exists across Local, Cloud, and WSL.

There’s also a practical behavior worth calling out: you can interrupt Claude immediately with the stop button, or type a correction and send it without stopping the current action. That’s a nice middle ground. I don’t always want to kill the run; sometimes I just want to steer it before the next step.

Preview, diff, and browser panes are the real review loop

Claude can start a dev server and open it in the Browser pane to verify its changes.

What this actually means is the app is trying to close the loop between edit and verification. It is not enough to generate code. The Code tab is built so Claude can run the app, inspect the result, and keep iterating. That matters because the fastest way to produce bad AI output is to let it edit blindly without seeing the result.

I like the Browser pane more than I expected. It can open your running app, static HTML, PDFs, images, and videos from the project. Claude can take screenshots, inspect the DOM, click elements, fill forms, and fix issues it finds. That’s not a toy feature. That’s the difference between “here’s a patch” and “here’s a patch I actually checked.”

The diff view is the other half of this. The docs say you can review and comment on diffs, then watch the resulting pull request through CI. That’s the workflow I want for anything nontrivial: edit, inspect, verify, then push. Not edit and pray.

How to apply it:

• Ask Claude to preview the app whenever the change affects UI or runtime behavior.
• Use the Browser pane for verification, not just for curiosity.
• Keep diff review in the loop even if the edits look plausible.
• If your app has a custom dev command, set it in .claude/launch.json so previewing works the way your project actually runs.

The docs also mention that cookies and local storage can persist across server restarts if you select Persist sessions. That’s one of those details that sounds small until you’re debugging auth flows and don’t want to log in every single time. I’ve wasted enough time on that elsewhere.

Side chats and parallel sessions are for staying sane

The sidebar lists your sessions and lets you run several in parallel.

What this actually means is that Claude Code Desktop expects you to multitask without collapsing everything into one thread. That’s a better fit for real dev work, where I might have one session fixing a bug, another investigating a flaky test, and a third drafting a docs update.

The docs also call out “ask a side question without derailing the session.” I think that’s one of the most practical ideas in the whole page. In a normal chat interface, a side question tends to hijack the thread. Here, the app is explicitly trying to let you keep the main task alive while asking for clarification or a quick check.

I’ve found this useful when I want Claude to explain a code path, but I don’t want that explanation to become the new mission. Same with background tasks. The app says you can watch them, work across sessions, and continue in another surface. That’s what I want from a desktop assistant: persistence without chaos.

How to apply it:

• Use a side question for clarification, not for a new task.
• Open a second session when the second task needs its own context.
• Keep long-running work in cloud or remote environments when you don’t want your local app lifecycle to matter.
• Use sessions as disposable workspaces, not as permanent diaries.

There’s also a nice connective tissue here with tools like Claude Code, Anthropic’s Claude Code page, and the broader Anthropic docs. The desktop app is not a separate universe. It sits in the same family of workflow ideas, just with a stronger GUI around them.

The template you can copy

# Claude Code Desktop session template

## Before I start
- Environment: Local / Cloud / SSH / WSL
- Project folder: /path/to/repo
- Model: pick the model before sending the first message
- Permission mode: Manual / Accept edits / Plan / Auto

## Session rule
One session = one task. If the task changes, open a new session.

## My default workflow
1. Start in Plan for anything unclear or multi-step.
2. Attach screenshots, specs, or files instead of describing them loosely.
3. Ask Claude to summarize the approach before editing.
4. Switch to Accept edits when the plan looks right.
5. Use the Browser pane or diff view to verify changes.
6. Keep side questions inside the session unless they become a new task.
7. Stop the run or correct it mid-flight if it starts drifting.

## Prompt starter
You are working in this repo only.
First, inspect the relevant files and explain the plan.
Then wait for approval before editing unless I switch to Accept edits.
If you make changes, show me the diff and tell me what you verified in the Browser or terminal.

## Safety defaults
- Do not use Bypass permissions unless I explicitly say so.
- Do not mix unrelated tasks into one session.
- Do not assume the same behavior across Local, Cloud, SSH, and WSL.
- If the app needs a custom dev server, check .claude/launch.json first.

## Good use cases
- UI bug fix with screenshots
- Repo cleanup with a visible diff
- Feature work that needs preview verification
- Long-running work in a cloud session
- Remote work over SSH

## Bad use cases
- One giant session for everything
- Blind edits without review
- Skipping the environment choice
- Using Bypass permissions on a real laptop

This is the part I’d actually keep around. It’s not fancy, but it matches the way the desktop app is built: bounded sessions, explicit environment, deliberate permission mode, and a review loop that includes the browser and diffs.

My honest take is that Claude Code Desktop works best when I stop asking it to be magical and start using it like a structured assistant workspace. The docs are pretty clear about that once you read past the feature list. Sessions are isolated, permissions are configurable, previews are built in, and the prompt box is more of a control surface than a text field. That’s the model I’d use.
