程序员阿江(Relakkes) 21efd1cf92 feat(desktop): round the tab corners and outline the selected tab
Tabs were hard to tell apart. The strip, the selected tab and the content
below it sit within 1.05–1.10:1 of each other in all six themes, so the
only thing marking selection was a 3px terracotta rule along the bottom —
and nothing at all separated two idle tabs from each other.

The obvious fix is Chrome's: darken the strip into a trough so the paper
tab pops out of it. That is the wrong trade here. The strip is continuous
with the sidebar, and darkening it turns the titlebar into a separate band
running across the top of the window instead of the same surface the
session list is already on. So the trough stays exactly --cc-s0, the fill
contrast stays where it was, and the shape is carried by two new per-theme
tokens instead:

- --cc-tab-edge (1.35:1 against the trough) outlines the selected tab.
  Without it the 8px top corners do not resolve at all — a curve is drawn
  by a colour boundary, and on 素白 there is none. This was measured, not
  assumed: a radius-only build is indistinguishable from the flat strip.
- --cc-tab-sep (1.22:1) is the hairline between two neighbouring idle tabs,
  and the same rule now divides the toolbar off (it was a full-height
  border-l, which read as a different kind of divider next to 16px ones).

Neither can reuse --color-border or --color-outline. Both are calibrated
against paper; on the trough they land at 1.12:1 (invisible) and 1.36–2.01
(a drawn box), in opposite directions between the light and ink families.
Both new tokens go *lighter* than the trough on dark and ink-blue for the
same structural reason --color-surface-hover was already banned here:
their paper is dark enough that pure black is only ~1.26:1 against it, so
there is no room downward.

Hover gets the weaker of the two outlines rather than none, giving three
legible tiers — no outline, hairline, full edge — because the same
1.05–1.10:1 that hides the selected tab's corners hides a hovered tab's.

Two things had to go for the corners to mean anything. The terracotta rule
and the strip's border-b both cut across the bottom edge that now has to
run unbroken into the content the tab opens onto; a rounded tab sitting on
a ruled line is just a clipped rectangle.

Chat tabs also lose the chat_bubble glyph. #1123 asked for icons and got
one on every kind including session, which is most of the strip, so the
row filled with identical bubbles saying nothing the titles did not. The
glyph now means "this tab is not a conversation". The slot animates its
own width rather than collapsing outright, so a session starting up still
does not jump its own title sideways — the bug the fixed slot was added
for. Spacing moved to per-child margin for the same reason: flex gap is
charged between children whatever their width.

contrast.test.ts gains 18 assertions pinning both tokens per theme,
including an upper bound on the hairline — too strong and the strip reads
as a table of cells. The three TabBar guards written against the old
square shape (no radius, 52px tab, the terracotta rule) are rewritten
rather than deleted, since what they were protecting — this is a document
tab, not a floating pill — still holds.

Desktop Preview

The Claude Code Haha desktop app brings sessions, multi-project navigation, branch / Worktree controls, file changes, diff review, permission approval, model setup, and remote access into one graphical workspace for daily development beyond the terminal.

v0.5.0 shipped a full UI redesign — six colour themes that can follow your system's light/dark setting. All six shots below are from a real v0.5.0 build.

Install the Desktop App

  1. Download the macOS / Windows / Linux desktop installer from Releases.
  2. On first launch, configure your model provider, API key, and default model in Settings.
  3. Public macOS releases require signing and notarization. Draft or unsigned temporary builds may still need one-time manual approval. Unsigned Windows installers may show SmartScreen; click "More info" -> "Run anyway". See the desktop installation guide.

Run the CLI from Source

For users who want to debug the underlying CLI, server, or local development flow:

bun install
cp .env.example .env
./bin/claude-haha

See environment variables and CLI setup for more configuration options.


Desktop Highlights

  • Multi-session workspace: tabs, project switching, terminal entry, and session history in one place, with a resizable sidebar.
  • Branch / Worktree launch: choose a repository branch and decide whether to use the current working tree or an isolated Worktree.
  • Review edits file by file: the workspace lists this turn's changes; open any file for a syntax-highlighted diff, or undo the whole turn.
  • Five permission modes: from "ask every time" to "skip permissions" — risky commands, tool calls, and follow-up questions are all approved in the GUI.
  • Bring your own model: sign in to Claude, ChatGPT, or Grok; use presets for DeepSeek, Kimi, Zhipu GLM and others; or point it at LM Studio and Ollama running locally.
  • Six colour themes: white, paper, warm classic, celadon, ink night, and ink blue — optionally following your system's light/dark setting.
  • Skill marketplace: discover, preview, and install third-party skills from ClawHub / SkillHub, with source and safety status shown up front.
  • Session activity panel: track task progress, background tasks, SubAgents, and sources in one side panel.
  • Computer Use: let the agent take screenshots, click, type, and control desktop apps after authorization.
  • Desktop pets: Dada, Huhu, Bubu, and Huihui change what they do with the task at hand — or raise one of your own (off by default).
  • H5 remote access: scan a QR code to continue the session in your phone browser; locking the screen won't kill a running task.
  • IM integration: chat, switch projects, and approve actions through Telegram / Feishu / WeChat / DingTalk / WhatsApp.
  • Scheduled tasks and usage stats: run planned tasks in their own sessions and track local token usage trends.
