opencode-look

Claude Code laid out like OpenCode, in your own theme's colours, with an OpenCode-style side pane.

Two plugins, install either or both:

Plugin	What it draws
opencode-look	Your messages in a block with an accent bar · replies with coloured bold, italics, code, list numbers and headings · a gutter so everything breathes · ▣ Done · Opus 5.5 · 27.5s after each turn · Claude · Opus 5.5 · xhigh under the prompt
toolbox	A side pane like OpenCode's sidebar: the folder as title · Context (tokens, % used, $ spent) · Pulse timer and hours · Next up from Google Calendar · MCP servers and their status · open Claude Sessions and what each is doing · folder and Claude Code version at the bottom

Install

From GitHub, typed at the Claude Code prompt:

/plugin install opencode-look --marketplace joakimunge/cc-opencode
/plugin install toolbox --marketplace joakimunge/cc-opencode

From a local clone:

git clone git@github.com:joakimunge/cc-opencode.git
claude plugin marketplace add ./cc-opencode
claude plugin install opencode-look@opencode-look
claude plugin install toolbox@opencode-look

Colours come from your theme

Nothing is a fixed colour. Each part uses a role, and the role is a key of whatever theme you picked with /theme:

Role	Theme key	In the Synthwave theme
Accent: the bar, ▣, headings, bullets	claude	pink
Bold	bashBorder	orange
Italics	warning	yellow
Code	success	green
List numbers, links	suggestion	cyan
Quiet text	inactive	lavender
Your message block	userMessageBackground	dark purple

Want OpenCode's exact look?

themes/opencode.json is OpenCode's Synthwave '84 as a Claude Code theme:

cp themes/opencode.json ~/.claude/themes/

Then pick OpenCode (Synthwave '84) in /theme, and set your terminal's background to #262335. Claude Code draws on the terminal's own background.

Prefer something quieter?

themes/opencode-graphite.json keeps the same pink, cyan and orange accents on muted greys instead of purples:

cp themes/opencode-graphite.json ~/.claude/themes/

Pick OpenCode (Graphite) in /theme, and set your terminal's background to #1f1f22, a soft charcoal rather than black.

Using tmux?

Inside tmux, Claude Code limits itself to 256 colours, which turns dark purples into flat grey. Add this to the env block of ~/.claude/settings.json and restart:

"CLAUDE_CODE_TMUX_TRUECOLOR": "1"

The side pane

• Opens by itself when a session starts (from about 110 columns wide in fullscreen).
• Hides when the terminal gets narrower than 110 columns, rather than stacking above the prompt, and comes back when you widen it.
• /toolbox opens it again · /toolbox refresh reads everything now · /toolbox close closes it · r refreshes · s stops the Pulse timer (it asks first).
• Pulse needs an MCP server named pulse. Next up needs the claude.ai Google Calendar connector; until it's logged in (/mcp) the pane says so.
• MCP status comes from claude mcp list, 15 s after the session starts and every 2 minutes after.

What it can't change

• The pane's × and the line beside it (the drag handle that resizes it) are Claude Code's own.
• The prompt box itself, and the plugins' load notices, are drawn by Claude Code and keep their place.

Developing

Each plugin is a hooks module (hooks/register.tsx) with pure helpers beside it and *.test.ts tests.

claude plugin validate plugins/opencode-look   # what the module hooks and calls
claude plugin test plugins/opencode-look       # the tests

To run your working copy in every session with live reload, list the plugin folders in CLAUDE_CODE_PLUGIN_DIRS (colon-separated) in the env block of ~/.claude/settings.json.
