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

# Design system

This is what the trace-mcp desktop app actually is, not what it aspires to be. Every
value here is read out of merged code and is cited to the file it lives in. If this
document and the code disagree, the code wins and this document is a bug.

The target is macOS 26 (Tahoe). The bar is not "consistent with the rest of the app" —
it is that a stranger opening trace-mcp assumes Apple shipped it.

**Read this before adding a screen.** It is meant to be read once, in order, and then
used as a checklist. Exact token values live in
`packages/app/src/renderer/styles/tokens.css`, which is the reference dump; this
document explains what each one is *for*.

## 1. The two-layer material model

There are exactly two layers, and mixing them is the single most common way to make
this app look wrong.

| Layer | What it is | Material |
|---|---|---|
| **Navigation / chrome** | sidebar, toolbars, floating control strips, menus, popovers | translucent — real vibrancy on macOS, `.glass` elsewhere |
| **Content** | everything in the content pane: cards, tables, rows, lists | **opaque** `--surface`, hairline border, no shadow |

Rules that fall out of this:
…

How to install

The exact contents, by fingerprint
mdr add nikolai-vysotskyi/trace-mcp/DESIGN.md@sha256:b425bffaa31dbaeb

The line at the top of this page pins the label git:20260906.e62dd88, 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.
