Examples

Start a new chat with the code-helper agent:

$ lmcli chat --agent code-helper

Start a new conversation, imperative style (no tui):

$ lmcli new "Help me plan meals for the next week"

Send a one-shot prompt (no persistence):

$ lmcli prompt "What is the answer to life, the universe, and everything?"

Agents

Agents in lmcli are configurations that combine a system prompt with a set of available tools. You can define agents in the config.yaml file and switch between them using the --agent or -a flag.

Example:

lmcli chat -a financier

Tools

lmcli supports various tool calling. Currently built-in tools are:

• dir_tree: Display a directory structure
• read_file: Read the contents of a file
• write_file: Write content to a file
• file_insert_lines: Insert lines at a specific position in a file
• file_replace_lines: Replace a range of lines in a file

Obviously, some of these tools carry significant risk. Use wisely :)
