TUI

Using the OpenCode terminal user interface.

OpenCode provides an interactive terminal interface or TUI for working on your projects with an LLM.

Running OpenCode starts the TUI for the current directory.

opencode

Or you can start it for a specific working directory.

opencode /path/to/project

Once you’re in the TUI, you can prompt it with a message.

Give me a quick summary of the codebase.

File references

You can reference files in your messages using @. This does a fuzzy file search in the current working directory.

How is auth handled in @packages/functions/src/api/index.ts?

The content of the file is added to the conversation automatically.

Configured references also appear in @ autocomplete. Type @alias to add the reference root as context, or type @alias/ to autocomplete files inside that reference.

Compare our setup with @docs/README.md

Bash commands

Start a message with ! to run a shell command.

!ls -la

The output of the command is added to the conversation as a tool result.
