opencode-session-title

Shows the session title right next to where you type. Without it, the only place to see which session you're in is the terminal tab at the top of the window. Claude Code shows it on the input box; this does the same for OpenCode.

The title sits dimmed at the right end of the agent/model row under the prompt:

┃  Build · Claude Opus 5.5 Cursor                   Displaying Session Title Above the Input Prompt…

It updates when the session is auto-titled or renamed. Long titles are cut with ... to fit the row, and in a window too narrow to show a useful part of it, the title hides.

Install

opencode plugin opencode-session-title -g

That installs the package into your global OpenCode config and adds it to tui.json. Drop -g for the current project only. Restart OpenCode afterwards; plugins load at startup.

Without npm

mkdir -p ~/.config/opencode/tui-plugins
curl -fsSL https://raw.githubusercontent.com/moritzWa/opencode-session-title/main/index.js \
  -o ~/.config/opencode/tui-plugins/session-title.js

Then add it to ~/.config/opencode/tui.json:

{
  "plugin": ["./tui-plugins/session-title.js"]
}

Options

{
  "plugin": [["opencode-session-title", { "max": 60 }]]
}

Option	Default	Meaning
max	48	Most columns the title takes before it is cut.
min	12	Below this many columns the title is hidden.

How it works

OpenCode's prompt has a session_prompt_right plugin slot on the agent/model row. The plugin renders a muted text node there and reads the title from api.state.session.get(sessionID), which is reactive.
