Minimal Claude Code statusline HUD, powered by Rust

best-claude-hud Overview

best-claude-hud is a high-performance Claude Code statusline tool written in Rust. It shows the status information you actually need while using Claude Code in a terminal: model, workspace, Git branch/status, context window usage, and optional usage/rate-limit metadata.

This project starts from the source code of Haleclipse/CCometixLine, then rebuilds the project under a new repository, package name, release workflow, and maintenance direction. The default goal is a compact single-line HUD, not a noisy multi-line dashboard.

The default statusline focuses on:

• Claude model display
• Claude Code launch directory, stable across temporary working-directory changes
• Git branch, clean/dirty/conflict state, and ahead/behind counts
• context window usage from Claude Code's official statusLine data, with active-transcript fallback
• optional usage/rate-limit, cost, session, and output style segments

Why This Fork Exists

The original CCometixLine is useful and feature-rich, but the maintenance queue has open PRs/issues that need review, compatibility fixes, and a clear default-output policy. best-claude-hud keeps the useful Rust/TUI foundation and makes the project easier to maintain as a public package.

Accepted in the initial rebuild:

• npm-first installation and platform optional dependencies
• no binary copy/link into ~/.claude
• Claude Code model input compatible with both string and object forms
• rate_limits parsed directly from Claude Code statusLine stdin before falling back to API polling
• context-window parsing fixed so a new terminal/session does not reuse stale token data from an older transcript
• interrupted responses no longer reset context usage to zero while waiting for the next API response
• workspace and Git segments anchored to workspace.project_dir so skills, subagents, and shell cd operations do not replace the project name
• git --no-optional-locks used for statusline Git commands

Install

best-claude-hud is distributed through npm. The npm package uses prebuilt native binaries; users do not need Rust installed.

Install and configure Claude Code in one line:

npm install -g best-claude-hud && best-claude-hud --setup

Restart Claude Code after setup. Existing sessions do not automatically reload ~/.claude/settings.json.

Install only:

npm install -g best-claude-hud

Using yarn or pnpm:

yarn global add best-claude-hud
pnpm add -g best-claude-hud

For users in China:

npm install -g best-claude-hud --registry https://registry.npmmirror.com && best-claude-hud --setup

Update an existing installation:

npm update -g best-claude-hud

Uninstall:

npm uninstall -g best-claude-hud

Nix

best-claude-hud also ships a Nix flake for declarative and reproducible environments.

Run without installing globally:

nix run github:GaoSSR/best-claude-hud -- --help

Install into a Nix profile:

nix profile install github:GaoSSR/best-claude-hud
best-claude-hud --setup

For home-manager or another declarative setup, point Claude Code directly at the Nix store binary:

# In your flake inputs:
# best-claude-hud.url = "github:GaoSSR/best-claude-hud";

{ inputs, pkgs, ... }:

let
  hud = inputs.best-claude-hud.packages.${pkgs.system}.default;
in
{
  home.packages = [ hud ];

  home.file.".claude/settings.json".text = builtins.toJSON {
    statusLine = {
      type = "command";
      command = "${hud}/bin/best-claude-hud";
      padding = 0;
    };
  };
}

If you already manage ~/.claude/settings.json with Nix, merge the statusLine block into your existing JSON instead of replacing the whole file.

Development shell:

nix develop

Claude Code Configuration

npm install -g best-claude-hud only installs the command. Claude Code will not show the HUD until statusLine is configured.

Recommended:

best-claude-hud --setup

The setup command writes a statusLine block to ~/.claude/settings.json and preserves existing settings. It resolves the installed command to an absolute path when possible:

{
  "statusLine": {
    "type": "command",
    "command": "/path/to/best-claude-hud",
    "padding": 0
  }
}

Manual configuration can also use "command": "best-claude-hud" if your Claude Code sessions inherit the same PATH as your shell. If statusLine already exists, --setup creates a timestamped backup next to settings.json before replacing it. Restart Claude Code after changing this file.

The npm package intentionally does not install a binary into ~/.claude. It uses the global npm command and resolves the matching native binary from Kiri-style npm alias optional dependencies.

Commands

best-claude-hud                    # open the interactive menu when run in a terminal
best-claude-hud --help             # print command help
best-claude-hud --version          # print version
best-claude-hud --setup            # configure Claude Code statusLine
best-claude-hud --config           # open the TUI configuration interface
best-claude-hud --theme minimal    # temporarily render with a built-in theme
best-claude-hud --patch <cli.js>   # patch Claude Code cli.js context warnings

Themes

Temporarily override the configured theme:

best-claude-hud --theme cometix
best-claude-hud --theme minimal
best-claude-hud --theme gruvbox
best-claude-hud --theme nord
best-claude-hud --theme powerline-dark
best-claude-hud --theme powerline-light
best-claude-hud --theme powerline-rose-pine
best-claude-hud --theme powerline-tokyo-night

Custom themes can be stored under:

~/.claude/best-claude-hud/themes/

Then use:

best-claude-hud --theme my-custom-theme

Configuration

Configuration files are stored under:

~/.claude/best-claude-hud/

Important files:

• config.toml: main HUD and segment configuration
• models.toml: model display names and context window limits
• themes/*.toml: custom theme presets
• .api_usage_cache.json: optional usage API cache
• .update_state.json: update-check state

Run the TUI configurator:

best-claude-hud --config

Available segment families:

• model
• directory
• git
• context_window
• usage
• cost
• session
• output_style
• update

Model Configuration

models.toml is created automatically on first run:

~/.claude/best-claude-hud/models.toml

It controls model display names and context limits. Claude model families are recognized automatically, while third-party models can be customized:

[[models]]
pattern = "kimi-k2.7"
display_name = "Kimi K2.7"
context_limit = 262144

[[models]]
pattern = "glm-5"
display_name = "GLM-5"
context_limit = 200000

[[models]]
pattern = "qwen3-coder"
display_name = "Qwen Coder"
context_limit = 256000

[[context_modifiers]]
pattern = "[1m]"
display_suffix = " 1M"
context_limit = 1000000

Statusline Data

Claude Code sends statusLine data to the command through stdin. best-claude-hud reads:

• model
• workspace.project_dir for the stable Claude Code launch directory
• workspace.current_dir as a fallback for older Claude Code versions
• transcript_path
• context_window
• cost
• output_style
• rate_limits

For context window usage, the HUD prefers Claude Code's official context_window fields. The active transcript is used only as a compatibility fallback when those fields are absent, null, or temporarily zero. All-zero usage placeholders written after an interrupted response are ignored, so pressing Esc does not erase the last valid context reading. A genuinely new session with no usage still shows 0% · 0 tokens and never scans older project history.

Git Status Indicators

• ✓: clean working tree
• ●: dirty working tree
• ⚠: conflicts
• ↑n: commits ahead of upstream
• ↓n: commits behind upstream

Git commands run with --no-optional-locks, so the HUD does not create unnecessary .git/index.lock contention while you work.

Claude Code Patch Utility

The inherited patcher can patch Claude Code cli.js to reduce context warning noise:

best-claude-hud --patch /path/to/claude-code/cli.js

Example:

best-claude-hud --patch ~/.local/share/fnm/node-versions/v24.4.1/installation/lib/node_modules/@anthropic-ai/claude-code/cli.js

The patcher creates a backup next to the target file before writing.

Platform Support

Requirements

• Claude Code with statusLine support
