coding-with-beat

The AI calls generate_profile() and returns:

• 📊 Top artists · genres · language breakdown
• 📈 Rising / stable / declining tastes
• 🕐 Time-of-day listening patterns
• 🎵 2–3 personalised smart_search queries ready to play

CLI (works offline, no MCP server needed):

cwb profile           # weekly (default)
cwb profile daily
cwb profile monthly
cwb profile yearly

Features

• MCP server — 38 tools so you can tell your AI "play some lofi", "skip this", "what's playing" and it just works.

• /cwb skill — Auto-registered routing brain: mood/vibe → multi-angle smart search, specific song/artist → catalog lookup, "play 3" → play_number. The AI always calls the right tool.

• Playlists — List and play your Apple Music playlists (user-created + subscription) directly from the AI: "我有哪些歌单" → numbered list → "播放周杰伦代表作". Queue syncs to cwb watch automatically.

• Play history — cwb history / list_history shows your recently played tracks sourced from Apple Music's native played date. history_search recommends new music based on your listening patterns.

• Music sources — Apple Music (AppleScript, no GUI needed), local files (afplay), QQ Music (search + preview).

• Pixel UI — Album art in half-block ANSI, GameBoy retro border, pseudo-spectrum equalizer.

• DJ Buddy — A headphones-wearing pixel character that reacts to your coding state. Tests failing? It panics with you.

• Vibe engine — CC hooks track what you're doing in real time and shift the mood. git commit? Victory pose. Tests explode? Panic mode.

• Statusline — One line: face + current track + progress bar.

• Focus mode — Built-in 25/5 Pomodoro timer shown in the statusline.

Installation

[!NOTE] Want to try the latest features before release? Check out the dev branch for cutting-edge updates.

Claude Code

curl -LsSf https://raw.githubusercontent.com/jaychempan/coding-with-beat/main/bootstrap.sh | sh

Or manually:

git clone https://github.com/jaychempan/coding-with-beat.git
cd coding-with-beat
./install.sh

The installer configures Claude Code to use the HTTP MCP endpoint at http://127.0.0.1:8765/mcp, saves that URL to ~/.coding-with-beat/mcp-url, and on macOS starts a user LaunchAgent for the local MCP server.

Open a new shell and a new Claude Code session. When (•_•) appears in the statusline, you're good.

Codex CLI

curl -LsSf https://raw.githubusercontent.com/jaychempan/coding-with-beat/main/bootstrap_codex.sh | sh

Or manually:

git clone https://github.com/jaychempan/coding-with-beat.git
cd coding-with-beat
./install_codex.sh

Installs Codex CLI if needed, configures ~/.codex/config.toml with the MCP endpoint, writes hooks, and installs the cwb skill so Codex recognises music commands automatically. Proxy is auto-detected. Re-running is safe — already-completed steps are skipped automatically.

See README_CODEX.md for the full integration guide — hooks, proxy, mood reactions, statusline alternatives, and debugging.

Usage

[!TIP] Not sure what to say? Just ask — DJ 能做什么 / DJ help — and DJ Buddy will show you a full list of phrases you can use.

Live player: Open a second terminal and run cwb watch to see the currently playing track, lyrics, and progress bar in real time.

Apple Music: The first time you play a catalog track, a popup will appear — click Add to Library, then repeat the play command.

Just talk to your AI assistant

play some lofi
skip this track
what's playing
pause
recommend something based on my history  # history_search — analyzes your patterns, suggests new tracks
show my recently played tracks           # list_history — reads Apple Music's native play log
基于我的历史推荐一些歌曲                    # same, in Chinese

history_search looks at your top artists, listening style, and tracks you haven't heard in a while, then runs a smart multi-angle search. Pick a number to play.

/cwb command

/cwb play "lofi beats"    # search and play
/cwb play lofi beats
/cwb search "lofi beats"  # search library + Apple Music, show numbered list
/cwb play 2               # play track #2 from last search / list results
/cwb list                 # list all library tracks
/cwb loved                # list loved/hearted tracks
/cwb playlists            # list all playlists (user + subscription)
/cwb play_playlist <name> # play a playlist by name
/cwb history [n]          # recently played tracks
/cwb next
/cwb pause
/cwb np                   # now playing
/cwb like
/cwb volume 70
/cwb watch                # live player (q to quit)
/cwb karaoke              # full-screen karaoke (q to quit)
/cwb lyrics               # lyrics window
/cwb bar auto             # statusline: auto / show / hide

Natural-language commands work too: skip this track, pause, what's playing, and like this are all valid.

Statusline

Once installed, a statusline appears at the bottom of Claude Code:

(•_•) ⚡  ▶ Midnight City — M83  ██████░░░░░░░░  [build]  ▃▆█▆▃  │ ♪ lyric preview

cwb statusline is the same renderer Claude Code uses. It reads optional JSON from stdin, uses columns as a width hint, and prints one compact status bar line to stdout.

printf '{"columns":120}' | cwb statusline

That makes it easy to plug into other status bars. For example, tmux can show CWB on the right side of its status bar:

tmux status-right

set -g status-right-length 180
set -g status-interval 1
set -g status-right '#(printf "{\"columns\":170}" | cwb statusline | perl -pe "s/\e\[[0-9;]*m//g")'

cwb statusline currently emits ANSI-coloured terminal text. The perl bit strips ANSI escape codes because tmux status formats use their own styling syntax. Increase or decrease columns and status-right-length to control how much room lyrics get.

Neovim statusline

Neovim can also show CWB in its statusline. Keep the shell call asynchronous so editing never waits on music state:

local cwb = { text = "", running = false }

local function strip_ansi(text)
  return text:gsub("\27%[[0-9;]*m", "")
end

local function refresh()
  if cwb.running or vim.fn.executable("cwb") == 0 then
    return
  end
  cwb.running = true
  vim.system({ "cwb", "statusline" }, {
    text = true,
    stdin = vim.json.encode({ columns = 90 }),
  }, function(result)
    vim.schedule(function()
      cwb.running = false
      if result.code == 0 and result.stdout then
        cwb.text = vim.trim(strip_ansi(result.stdout)):gsub("%%", "%%%%")
        vim.cmd.redrawstatus()
      end
    end)
  end)
end

_G.cwb = cwb
vim.fn.timer_start(1000, refresh, { ["repeat"] = -1 })
refresh()
vim.o.statusline = "%f %m%r %= %{v:lua.cwb.text}"

SSH Remote (Claude Code / Codex CLI on a server)

If your AI CLI runs on a remote server while Apple Music runs on your local Mac, run the streamable HTTP MCP server on the Mac and reach it from the server through SSH reverse port forwarding:

# Local Mac: install and start the HTTP MCP LaunchAgent
./install.sh          # for Claude Code
./install_codex.sh    # for Codex CLI

# Local Mac: expose it to the server's 127.0.0.1:8765
ssh -N -R 127.0.0.1:8765:127.0.0.1:8765 user@server

# Server: install hooks/statusline and point them at the forwarded endpoint
./install.sh --mcp-url http://127.0.0.1:8765/mcp          # Claude Code
./install_codex.sh --mcp-url http://127.0.0.1:8765/mcp    # Codex CLI

The remote session, /cwb, statusline, hooks, and cwb CLI all use the same HTTP MCP URL. As long as the SSH tunnel is up, comm
