Usage: /network {command} <host>

Error message

Usage: /network {command} <host>

What it means

Usage error from the `/network` slash command: the subcommands `allow`, `deny`, `remove`, and `forget` each require exactly one host argument. When the host argument is missing, the command bails with this usage string instead of mutating policy. No network policy state is changed.

Solutions

1. Supply the host: `/network allow api.deepseek.com`
2. Run `/network` bare or `/network list` to see current policy and valid forms
3. Check the full usage string at the bottom of the command's output

Example fix

// before
/network allow

// after
/network allow api.deepseek.com

let tokens: Vec<&str> = raw.split_whitespace().collect();
if matches!(tokens.first().copied(), Some("allow" | "deny" | "remove" | "forget")) {
    anyhow::ensure!(tokens.len() == 2, "Usage: /network {} <host>", tokens[0]);
}

fn host_edit_is_well_formed(tokens: &[&str]) -> bool {
    matches!(tokens.first().copied(), Some("allow" | "deny" | "remove" | "forget"))
        && tokens.len() == 2
}

When it happens

Trigger: Running `/network allow`, `/network deny`, `/network remove`, or `/network forget` with no host token after the subcommand.

Common situations: Typing the command from memory and forgetting the host; tab-completion not offering a host; copy-pasting a truncated example.
