Description
Feature request
Today OpenCode lets you control which tools run (permissions, custom tools, MCP servers) and offers global UI theming, but it does not allow customizing how each tool call is displayed.
What I'd like
Per-tool visual customization, for example:
- Custom icon / emoji per tool (e.g. ash, edit, custom MCP tools)
- Custom display label / rename in the UI
- Control over collapsed vs expanded default layout per tool
- Optional custom color/accent for a tool's block
Why
Different tools have very different weight in a session (a ash run vs a
ead). Letting users visually distinguish them by style would make long sessions much easier to scan.
Current workaround
Only global \ hemes\ are available; they don't change per-tool rendering.
