Author a Wisp custom theme CSS file that uses documented tokens and import constraints. Use when the user wants a custom look, hide the paragraph lead bar, restyle chat Markdown, override colors, or import a stylesheet under Settings → Appearance.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Custom Wisp theme CSS
Wisp injects one user stylesheet after the built-in theme. Prefer CSS variables
on `:root`. Do not invent Settings toggles for one-off look changes.
## Workflow
1. Ask what should change (lead bar, table size, accent, chat density, fonts).
2. Write a `.css` file in the project, usually `theme.css`.
3. Apply it:
- Desktop: `configure` with `action=set` and `values.custom_css` set to the
full stylesheet text. Empty string clears it.
- Or tell the user to import the file under **Settings → Appearance**.
4. Confirm the change is visible. If a rule did nothing, the selector is wrong;
do not add `!important` unless a built-in rule requires it.
## Constraints
The host sanitizes CSS before inject. These are stripped:
- `@import` and `@namespace`
- every `url(...)`
- `javascript:`, `expression(`, `behavior:`, `-moz-binding`
- `</style` and `<script`
- NULs; payload longer than 64 KB is truncated
Do not rely on remote fonts, images, or other stylesheets. Name an installed
font with `configure` `ui_font_family` / `code_font_family` instead.
Scope light/dark overrides with `:root[data-theme="light"]` and
…Read the whole file at its exact version.
How to install
mdr add xuzhougeng/wisp-science/custom-theme@sha256:2810194aa183f599The line at the top of this page pins the label git:20260815.714d315, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
