# Sketch has evolved into Shelley
See https://blog.exe.dev/shelley for details.
**Sketch is no longer maintained.**
You can **[try Shelley at exe.dev](https://exe.dev)** or **[check out the Shelley GitHub repo](https://github.com/boldsoftware/shelley)**.

**Sketch is an agentic coding tool. It draws the 🦉**
## 🚀 Overview
Sketch runs in your terminal, has a web UI, understands your code, and helps
you get work done. To keep your environment pristine, sketch starts a docker
container and outputs its work onto a branch in your host git repository.
Sketch helps with most programming environments, but Sketch has extra goodies for Go.
## 📋 Quick Start
### Install via Homebrew
```sh
brew install boldsoftware/tap/sketch
```
Update to the latest version by running `brew upgrade boldsoftware/tap/sketch`.
### Install via GitHub Releases
Grab the most recent [nightly release](https://github.com/boldsoftware/sketch/releases).
Update by running `sketch -update`.
### Build from source
Clone this repo, and then run:
```sh
$ make
$ ./sketch
```
## 🔧 Requirements
Currently, Sketch runs on MacOS and Linux. It uses Docker for containers.
| Platform | Installation |
| -------- | -------------------------------------------------------------------------- |
| MacOS | `brew install colima` (or [OrbStack](https://orbstack.dev/) or [Docker Desktop](https://www.docker.com/products/docker-desktop/)) |
| Linux | `apt install docker.io` (or equivalent for your distro) |
| WSL2 | Install Docker Desktop for Windows (docker entirely inside WSL2 is tricky) |

## 📖 User Guide
### Getting Started
Start Sketch by running `sketch` in a Git repository. It will open your browser to the Sketch chat interface, but you can also use the CLI interface. Use `-open=false` if you want to use just the CLI interface.
Ask Sketch about your codebase or ask it to implement a feature. It may take a little while for Sketch to do its work, so hit the bell (🔔) icon to enable browser notifications. We won't spam you or anything; it will notify you
when the Sketch agent's turn is done, and there's something to look at.
### How Sketch Works
When you start Sketch, it:
1. Creates a Dockerfile
2. Builds it
3. Copies your repository into it
4. Starts a Docker container with the "inside" Sketch running
This design lets you **run multiple sketches in parallel** since they each have their own sandbox. It also lets Sketch work without worry: it can trash its own container, but it can't trash your machine.
Sketch's agentic loop uses tool calls (mostly shell commands, but also a handful of other important tools) to allow the LLM to interact with your codebase.
### Getting Your Git Changes Out
Sketch is trained to make Git commits. When those happen, they are
automatically pushed to the git repository where you started sketch with branch
names `sketch/*`.
**Finding Sketch branches:**
```sh
git branch -a --sort=creatordate | grep sketch/ | tail
```
The UI keeps track of the latest branch it pushed and displays it prominently. You can use standard Git workflows to pull those branches into your workspace:
```sh
git cherry-pick $(git merge-base origin/main sketch/foo)
```
or merge the branch
```sh
git merge sketch/foo
```
or reset to the branch
```sh
git reset --hard sketch/foo
```
Ie use the same workflows you would if you were pulling in a friend's Pull Request.
**Advanced:** You can ask Sketch to `git fetch sketch-host` and rebase onto another commit. This will also fetch where you started Sketch, and we do a bit of "git fetch refspec configuration" to make `origin/main` work as a git reference.
Don't be afraid of asking Sketch to help you rebase, merge/squash commits, rewrite commit messages, and so forth; it's good at it!
### Reviewing Diffs
The diff view shows you changes since Sketch started. Leaving comments on lines
adds them to the chat box, and, when you hit Send (at the bottom of the page), Sketch goes to work addressing your
comments.
### Connecting to Sketch's Container
You can interact directly with the container in three ways:
1. **Web UI Terminal**: Use the "Terminal" tab in the UI
2. **SSH**: Look at the startup logs or click the information icon to see a command like `ssh sketch-ilik-eske-tcha-lott`.
We have automatically configured your SSH configuration to make these special hostnames work.
3. **Visual Studio Code**: Look for a command line or magic link behind the information icon, or when Sketch starts up. This starts a new VSCode session "remoted into" the container. You
can edit the code, use the terminal, review diffs, and so forth.
Using SSH (and/or VSCode) allows you to forward ports from the container to your machine. For example, if you want to start your development webserver, you can do something like this:
```sh
# Forward container port 8888 to local port 8000
ssh -L8000:localhost:8888 sketch-ilik-epor-tfor-ward go run ./cmd/server
```
This makes `http://localhost:8000/` on your machine point to `localhost:8888` inside the container.
### Using Browser Tools
You can ask Sketch to browse a web page and take screenshots. There are tools
both for taking screenshots and "reading images", the latter of which sends the
image to the LLM. This functionality is handy if you're working on a web page and
want to see what the in-progress change looks like.
## ❓ FAQ
### "No space left on device"
Docker images, containers, and so forth tend to pile up. Ask Docker to prune unused images and containers:
```sh
docker system prune -a
```
