nerdflair

Configure the nerdflair statusline. This skill handles both first-time install and ongoing configuration.

Base directory for this skill: $CLAUDE_PLUGIN_ROOT

First: check what the user asked for

If the user provided arguments (e.g., /nerdflair install, /nerdflair layout full), handle that request directly using the Install or Configure sections below.

If the user invoked /nerdflair with NO arguments, first run info to get the current state, then display a complete command reference showing current settings and all available commands. Format it like a CLI help page:

1. Show current settings from info output as a formatted summary
2. List ALL available commands alphabetically with their current values and what they do:

nerdflair

Current settings:
  layout: full   width: auto
  terminal-bell: on   chimes: on (BalladPiano)   color-palette: vibrant

Commands:
  /nerdflair chime-events       Show/toggle which events play chimes
  /nerdflair chime-session [style] Set chime for this session only (plays preview)
  /nerdflair chime-style [style]   Set or cycle global chime style (random, BalladPiano, ...)
  /nerdflair chime-volume [0-100]  Set chime volume (0 = muted)
  /nerdflair color-palette [mode]  Set or cycle palette (vibrant, muted, mono)
  /nerdflair layout [mode]      Set or cycle layout (full, compact, minimal)
  /nerdflair install             Install or upgrade (font check, settings.json; preserves settings)
  /nerdflair uninstall           Remove nerdflair from settings and clean up data
  /nerdflair spinner-verbs      Show/manage custom spinner verbs
  /nerdflair terminal-bell      Toggle terminal bell on/off (tab indicator)
  /nerdflair width [auto|50-150]   Set layout width

Stop after displaying the help. Do NOT prompt the user or use AskUserQuestion — just print the settings and commands, then wait for the user to run a command themselves.

Install

Step 0: Check jq

jq is required -- the statusline and configurator parse JSON with it, and the install script exits immediately if it's missing.

command -v jq >/dev/null 2>&1 && echo "jq found" || echo "jq MISSING"

If found: Continue to Step 1.

If missing: Use AskUserQuestion with header "jq":

Question: "nerdflair requires jq to run. How would you like to install it?"

Options:

1. Homebrew (recommended) - "Install jq via brew (macOS)"
2. apt - "Install jq via apt (Debian/Ubuntu)"
3. Skip for now - "I'll install jq later (the statusline won't run without it)"

Handle each response:

• Homebrew: Run brew install jq, then continue to Step 1.
• apt: Run sudo apt install jq, then continue to Step 1.
• Skip for now: Warn that the statusline will not render until jq is installed, then stop (do not run the install script -- it will fail).

Step 1: Check Nerd Font

A Nerd Font is required -- the progress bar, icons, and Powerline caps all use Nerd Font glyphs. Without one, the statusline renders as broken boxes.

find ~/Library/Fonts /Library/Fonts -maxdepth 1 -iname '*nerd*' 2>/dev/null | head -5

If fonts are found: Tell the user and continue to Step 2.

If no fonts found: Use AskUserQuestion with header "Nerd Font":

Question: "nerdflair requires a Nerd Font for icons and the progress bar. How would you like to install one?"

Options:

1. Homebrew (recommended) - "Install JetBrains Mono Nerd Font via brew"
2. I already have one - "My terminal is already configured with a Nerd Font"
3. Skip for now - "I'll install a font later (statusline will look broken)"

Handle each response:

• Homebrew: Run brew install --cask font-jetbrains-mono-nerd-font, then continue to Step 1b.
• I already have one: Continue to Step 1b.
• Skip for now: Warn that icons will render as boxes, then skip to Step 2.

Step 1b: Configure the terminal font

Installing a font only puts the files on disk -- the user must also select it in their terminal app. Use AskUserQuestion with header "Terminal Font Setup":

Question: "Which terminal are you using? I'll give you the exact steps to activate the Nerd Font."

Options:

1. iTerm2
2. Terminal.app
3. Warp
4. Ghostty
5. VS Code integrated terminal
6. Other / I'll figure it out

Give terminal-specific instructions based on their selection:

• iTerm2: Open Settings (Cmd+,) -> Profiles -> Text -> Font -> select "JetBrainsMono Nerd Font" from the dropdown. If you have multiple profiles, update the one marked as Default.
• Terminal.app: Open Settings (Cmd+,) -> Profiles -> select your active profile -> click "Font" -> click "Change..." -> find and select "JetBrainsMono Nerd Font" -> set your preferred size -> click Done.
• Warp: Open Settings (Cmd+,) -> Appearance -> scroll to "Terminal font" -> select "JetBrainsMono Nerd Font".
• Ghostty: Add font-family = JetBrainsMono Nerd Font to ~/.config/ghostty/config (create the file if it doesn't exist), then restart Ghostty.
• VS Code integrated terminal: Open Settings (Cmd+,) -> search "terminal font" -> set Terminal > Integrated: Font Family to JetBrainsMono Nerd Font. Alternatively, add "terminal.integrated.fontFamily": "JetBrainsMono Nerd Font" to your settings.json.
• Other: Tell the user to find their terminal's font settings and select "JetBrainsMono Nerd Font" (or whichever Nerd Font they installed).

After giving instructions, tell the user they can verify with echo "" -- if they see a box or question mark instead of an icon, the font isn't active yet.

Step 2: Initialize state and configure statusLine

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" install

This is idempotent: on first install it creates state with defaults; on upgrade it preserves existing settings. It also updates the statusLine entry in ~/.claude/settings.json to use ${CLAUDE_PLUGIN_ROOT}.

Before running, check if a non-nerdflair statusLine is already configured:

• If statusLine is absent or already points to nerdflair (command contains nerdflair): proceed.
• If statusLine exists and points to something else: warn the user that a different statusline is configured and use AskUserQuestion to ask whether to replace it. Show the current command. If they decline, skip this step.

Step 3: Enable spinner verbs

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" spinner-verbs enable

This loads the custom thinking/spinner phrases from assets/text/spinners.txt into ~/.claude/settings.json. If existing non-nerdflair spinner verbs are present, they are backed up first. If nerdflair verbs are already installed, they are refreshed in place (no backup needed).

Step 4: Verify and summarize

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" info
bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" chime-events

Display a summary table of settings from the info output. Format the table as follows:

• Bold the Setting and Value column headers
• Title-case the values (e.g. "Full", "Vibrant", "On", "Auto", "Random (per session)") for readability
• Alphabetize the rows by setting name
• For chime events, list the actual enabled event names (from the chime-events output) instead of just a count
• Do NOT include a "Font" row (we only check for fonts to help install -- we can't tell which font the terminal is actually using)
• Do NOT include the statusline command path

Tell the user to restart Claude Code for the changes to take effect.

Configure

Run the appropriate command based on what the user asked for. After running it, briefly confirm the change. The effect is visible on the next statusline render.

Examples

Cycle to the next layout:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" layout

Set layout directly:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" layout full

Cycle chime style (random -> BalladPiano -> DelicateBells -> ...):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" chime-style

Set chime for this session only (plays SessionStart sound):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" chime-session Vibraphone

List available session chime styles (no argument):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" chime-session

When the user runs /nerdflair chime-session with no argument, run the command above to get the numbered list, then use AskUserQuestion to let them pick a style (use the numbered style names as options). After they choose, run chime-session <name> or chime-session <number> to apply it.

Set chime volume (0 = muted, 100 = full):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" chime-volume 50

Cycle color palette (vibrant -> muted -> mono):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" color-palette

Toggle terminal bell on/off (tab indicator on Notification, PermissionRequest, Stop):

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" terminal-bell

Set width:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" width 60

Reset width to auto:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" width auto

Show current settings without changing anything:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" info

Layout

• layout: cycles or sets the statusline mode
  • full: 3 rows -- folder/branch, progress bar, mcp/cost
  • compact: 2 rows -- folder/branch, progress bar (cost folded into bar label)
  • minimal: 1 row -- progress bar only
• Cycle order: full -> compact -> minimal -> full

Width

• width: sets the layout width (50-150, or "auto")
  • auto (default): 80 columns
  • 50-150: fixed bar width in columns

Terminal Bell

• terminal-bell: toggles the terminal bell (BEL character) on/off (default: on)
  • The BEL fires on 3 hard-coded events only: Notification, PermissionRequest, Stop
  • Shows a tab indicator in terminals that support BEL (Ghostty, iTerm2, Terminal.app, Kitty, WezTerm, etc.)
  • The bell events are not user-configurable (use chime-events to control which events play audio)

Chimes

• chime-volume: sets the chime playback volume (0-100, default 100)
  • 0 = muted (no audio plays)
  • Affects all sessions (plugin-wide setting)
  • Shown in the statusline next to chime style when not 100%
• chime-style: cycles through audio styles (run ls "$CLAUDE_PLUGIN_ROOT/assets/audio/" to discover available styles; "random" is always an option)
  • "random" picks a style per session (locked to session_id, persists across context clears)
  • Each style has per-event sounds (Notification, PermissionRequest, Stop, etc.)
• chime-session: set the chime style for the current session only (does not change global setting)
  • Overrides the global chime-style (or the random pick) for this session
  • Plays the SessionStart sound immediately so you can hear the style
  • Resets when the session ends (session file is cleaned up)
  • No argument: lists available styles numbered (use AskUserQuestion to let user pick)
  • With argument: set directly by name or number: chime-session Vibraphone or chime-session 19
• chime-events: user-configurable list of events that play audio chimes (default: Notification, PermissionRequest, SessionEnd, SessionStart, Stop)
  • Available events: Notification, PermissionRequest, PreCompact, SessionEnd, SessionStart, Stop, UserPromptSubmit
  • Toggle individual events with chime-events <EventName>

Spinner Verbs

• spinner-verbs: toggle nerdflair's custom spinner/thinking text on or off
• The shimmering text shown while Claude is working (e.g. "Thinking...", "Reasoning...")
• When enabled, loads verbs from $CLAUDE_PLUGIN_ROOT/assets/text/spinners.txt (one per line) into ~/.claude/settings.json
• When disabled, removes the spinnerVerbs field from settings (restores Claude Code defaults)
• Users can also edit assets/text/spinners.txt directly to customize the verb list
• Changes require a Claude Code restart to take effect
• spinner-verbs (no args): toggle on/off
• spinner-verbs enable: enable nerdflair verbs
• spinner-verbs disable: disable (restore defaults)

Examples:

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" spinner-verbs
bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" spinner-verbs enable
bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" spinner-verbs disable

Color Palette

• color-palette: cycles the color palette -- vibrant -> muted -> mono -> vibrant
• vibrant: full-color palette (blues, greens, ambers, reds)
• muted: same hues as vibrant but desaturated (~40% saturation) for a subdued look
• mono: grayscale only -- all text and progress bar gradients use shades of gray

Uninstall

• uninstall: removes all nerdflair traces from ~/.claude/
  • Removes spinnerVerbs from ~/.claude/settings.json
  • Removes statusLine from ~/.claude/settings.json
  • Removes ~/.claude/nerdflair/ directory (state, sessions)
  • The plugin files themselves remain in place — disable or remove the plugin from Claude Code settings to fully remove

bash "$CLAUDE_PLUGIN_ROOT/scripts/nerdflair.sh" uninstall
