StatusLine Config

Customize ~/.claude/statusline-command.sh — segments, themes, and colors.

When NOT to Use

Scenario	Use Instead
Setting statusline for the first time (no customization needed)	Built-in `statusline-setup` agent (Claude Code agent type) — applies defaults automatically
Editing `settings.json` directly	Manual edit — this skill manages `statusline-command.sh`, not `settings.json`
Debugging Claude Code startup issues	`/claude-health` — config health check

Segments

Segment	JSON Field	Default	Notes
Directory	`workspace.current_dir`	ON	Truncate deep paths: `~/.../last-dir`
Git branch	shell `git`	ON	`--no-optional-locks`, cache 5s
Model	`model.display_name`	ON	-
Context %	`context_window.remaining_percentage`	ON	Green >40%, Yellow 20-40%, Red <=20%
Cost	`cost.total_cost_usd`	ON	Show when >= $0.005, `est $X.XX`
>200k alert	`exceeds_200k_tokens`	ON	Show only when `true`

For full JSON schema, see json-schema.md.

Themes

Theme	Type	Default	Notes
`ansi-default`	ANSI 16	✅	Safe fallback, works everywhere
`catppuccin-mocha`	TrueColor	—	Recommended — pastel, WCAG AA >=4.5:1
`dracula`	TrueColor	—	Vibrant purple/pink accents
`nord`	TrueColor	—	Arctic blue, muted tones
`none`	—	—	No colors (`NO_COLOR` auto-triggers)

Switch via: export CLAUDE_STATUSLINE_THEME=catppuccin-mocha

For complete token→hex mappings, see themes.md.

Semantic Tokens

Scripts use semantic tokens instead of hardcoded colors:

Token	Role	Example
`C_CWD`	Directory path	blue / sapphire
`C_BRANCH`	Git branch name	magenta / mauve
`C_MODEL`	Model display name	cyan / teal
`C_CTX_OK`	Context >= 41%	green
`C_CTX_WARN`	Context 21-40%	yellow
`C_CTX_BAD`	Context <= 20%	red
`C_COST`	Cost display	muted text
`C_ALERT`	>200k token warning	orange/peach + bold
`C_SEP`	Pipe separator `\|`	dim/overlay
`C_MUTED`	Secondary info	subtext
`C_TEXT`	General text	foreground
`C_RESET`	Reset all formatting	`\033[0m`

Workflow

No args → Apply best-practice defaults (all ON segments + ansi-default theme). Go to step 4.

Theme change (e.g. "use catppuccin-mocha", "switch to dracula") → Read themes.md, apply requested theme. Go to step 4. Aliases: catppuccin → catppuccin-mocha.

Custom requests (e.g. "add cost", "remove git", "no colors") → Interactive flow:

Read current script: cat ~/.claude/statusline-command.sh
Ask segments to enable/disable (AskUserQuestion multiSelect)
Ask theme preference (AskUserQuestion with theme options)
Generate script following Script Rules + selected theme from themes.md
Write to ~/.claude/statusline-command.sh
Verify: echo '{"model":{"display_name":"Opus 4.6"},"workspace":{"current_dir":"/tmp/test"},"context_window":{"remaining_percentage":55},"cost":{"total_cost_usd":0.42},"exceeds_200k_tokens":false}' | ~/.claude/statusline-command.sh

Script Rules

Shebang: #!/bin/sh (POSIX)
Read stdin: input=$(cat)
Parse JSON: jq -r '.field // fallback'
Theme from env: theme="${CLAUDE_STATUSLINE_THEME:-ansi-default}"
NO_COLOR: [ -n "${NO_COLOR:-}" ] && theme="none"
Theme aliases: catppuccin → catppuccin-mocha
Invalid theme: fallback to ansi-default
Color output: printf "%b" for ANSI/TrueColor, printf "%s" for none
TrueColor format: \033[38;2;R;G;Bm (24-bit foreground)
Git: git --no-optional-locks -C "$dir"
Git cache: /tmp/claude-statusline-git-cache-$(id -u), 5s TTL, stat -f %m (macOS) / stat -c %Y (Linux)
CWD truncation: depth >2 → ~/.../basename
Cost: only when >= 0.005, format est $X.XX
Alert style: C_ALERT + bold (\033[1m) to distinguish from C_CTX_BAD

Script Structure

#!/bin/sh
input=$(cat)
# ... extract JSON fields ...

theme="${CLAUDE_STATUSLINE_THEME:-ansi-default}"
[ -n "${NO_COLOR:-}" ] && theme="none"

case "$theme" in
  catppuccin|catppuccin-mocha) # set C_* tokens with TrueColor values ;;
  dracula)          # ... ;;
  nord)             # ... ;;
  none)             # all C_* = "" ;;
  *)                # ansi-default: ANSI 16 colors ;;
esac

# ... build output using C_* tokens ...
if [ "$theme" = "none" ]; then
  printf "%s" "$out"
else
  printf "%b" "$out"
fi

Example Output

~/.../my-project | feat/auth | Opus 4.6 | ctx 48% left · est $0.12
~/.../my-project | main | Opus 4.6 | ctx 18% left · est $1.23 · >200k

Output

Artifact	Path	Description
StatusLine script	`~/.claude/statusline-command.sh`	POSIX shell script consuming JSON stdin

Verification

After generating the script, verify:

~/.claude/statusline-command.sh exists and is executable (chmod +x)
Test echo passes: echo '{"model":{"display_name":"Opus 4.6"},"workspace":{"current_dir":"/tmp/test"},"context_window":{"remaining_percentage":55},"cost":{"total_cost_usd":0.42},"exceeds_200k_tokens":false}' | ~/.claude/statusline-command.sh
Output contains expected segments (directory, model, context %)
Theme matches user selection (check color codes in script)
NO_COLOR=1 produces uncolored output
