## Custom Commands
OpenCode supports custom commands that can be created by users to quickly send predefined prompts to the AI assistant.
### Creating Custom Commands
Custom commands are predefined prompts stored as Markdown files in one of three locations:
1. **User Commands** (prefixed with `user:`):
```
$XDG_CONFIG_HOME/opencode/commands/
```
(typically `~/.config/opencode/commands/` on Linux/macOS)
or
```
$HOME/.opencode/commands/
```
2. **Project Commands** (prefixed with `project:`):
```
<PROJECT DIR>/.opencode/commands/
```
Each `.md` file in these directories becomes a custom command. The file name (without extension) becomes the command ID.
For example, creating a file at `~/.config/opencode/commands/prime-context.md` with content:
```markdown
RUN git ls-files
READ README.md
```
This creates a command called `user:prime-context`.
### Command Arguments
You can create commands that accept arguments by including the `$ARGUMENTS` placeholder in your command file:
```markdown
RUN git show $ARGUMENTS
```
When you run this command, OpenCode will prompt you to enter the text that should replace `$ARGUMENTS`.
### Organizing Commands
You can organize commands in subdirectories:
```
~/.config/opencode/commands/git/commit.md
```
This creates a command with ID `user:git:commit`.
### Using Custom Commands
1. Press `Ctrl+K` to open the command dialog
2. Select your custom command (prefixed with either `user:` or `project:`)
3. Press Enter to execute the command
The content of the command file will be sent as a message to the AI assistant.
## MCP (Model Context Protocol)
OpenCode implements the Model Context Protocol (MCP) to extend its capabilities through external tools. MCP provides a standardized way for the AI assistant to interact with external services and tools.
