opencode doesn't work well in ubuntu 26.04 at vscode terminal

Description

When I use VS Code, neither its built-in terminal nor the terminal popped up by the extension "opencode" can properly open the slash‑type command pop‑up (i.e., the autocomplete/suggestion window triggered by typing a slash). There is no response. However, the default terminal in the Ubuntu system works fine.

Steps to reproduce

Step 1 – Verify the normal environment (system terminal)

Open the default Ubuntu terminal (e.g., GNOME Terminal).

Ensure the shell used is the same as the one in VS Code (typically bash or zsh).

Type /skill and press Enter.

Observe whether a skill list (interactive menu or completion pop‑up) appears immediately. Record this normal behavior as your baseline.

Step 2 – Test in the VS Code built‑in terminal

Launch VS Code and open any project or an empty workspace.

Press Ctrl+` to open the built‑in terminal.

At the prompt, type /skill and press Enter.

Observe the result:

Does any dropdown menu, completion list, or selection prompt appear?

Does the cursor remain, or does the command line clear or execute something else?

If no skill list appears and the terminal only echoes /skill or shows a “command not found” message, then the issue is reproduced in this terminal.

Step 3 – Test in the opencode extension’s terminal

Make sure the opencode extension is installed and enabled.

Open its separate terminal window via the extension’s entry point (e.g., sidebar icon or Command Palette command “OpenCode: Open Terminal”).

Again type /skill and press Enter.

Check whether the behavior matches the VS Code built‑in terminal (no list appears). If it does, the issue is reproduced in that terminal as well.
