*Citation needed.
A terminal theme pack, Claude Code statusline collection, and session analytics dashboard — all in a cohesive blue palette. Ships terminal color profiles, statusline scripts, shell prompt themes, and automatic session tracking — so your entire Claude Code experience feels like one thing.

claudeblue previewClaudeBlue automatically tracks every Claude Code session — cost, model, context consumption, and working directory. A Stop hook silently appends a line to ~/.claudeblue/history.jsonl each time a session ends.
Shows cost summaries by period, model breakdown with bar charts, a daily spend chart, and your most active projects:

claudeblue stats --resetThe installer registers a Claude Code Stop hook in ~/.claude/settings.json:
{
"hooks": {
"Stop": [
{
"matcher": "",
"hooks": [
{
"type": "command",
"command": "~/.claudeblue/hooks/session-log.sh"
}
]
}
]
}
}Each time a Claude Code session ends, the hook captures these environment variables and appends a JSON line to ~/.claudeblue/history.jsonl:
| Variable | What it captures |
|---|---|
CLAUDE_MODEL |
Model used (e.g., claude-opus-4-6) |
CLAUDE_SESSION_COST |
Total session cost in USD |
CLAUDE_CONTEXT_TOKENS |
Tokens used in context window |
CLAUDE_CONTEXT_MAX |
Maximum context window size |
PWD |
Working directory (project) |
Example JSONL entry:
{"ts":"2026-03-21T14:30:00Z","model":"claude-opus-4-6","cost":"3.45","ctx_used":500000,"ctx_max":1000000,"cwd":"/Users/you/code/myapp"}All data stays local on your machine. Nothing is sent anywhere.
Ready-to-import profiles for your terminal emulator, in Midnight (dark) and Light variants:

After install, your Claude Code settings.json includes a statusline and session tracking hook:
{
"statusLine": {
"type": "command",
"command": "~/.claudeblue/statusline.sh"
},
"hooks": {
"Stop": [
{
"matcher": "",
"hooks": [
{ "type": "command", "command": "~/.claudeblue/hooks/session-log.sh" }
]
}
]
}
}To customize the statusline, edit ~/.claudeblue/config:
CLAUDEBLUE_THEME="midnight" # glacier | midnight | electric
CLAUDEBLUE_SHOW_COST=true # show session cost
CLAUDEBLUE_SHOW_MODEL=true # show active model
CLAUDEBLUE_SHOW_GIT=true # show git branch + status
CLAUDEBLUE_SHOW_CONTEXT=true # show context window barclaudeblue <command> [args]
Commands:
install Install ClaudeBlue and configure Claude Code
use [theme] Switch active theme (glacier, midnight, electric)
preview Preview all themes with simulated data
status Show current configuration
stats Session analytics dashboard
stats --json Dump raw session data as JSONL
stats --reset Clear all session history
history [N] Show last N sessions (default: 20)
uninstall Remove ClaudeBlue
help Show help
- bash 4+ (macOS ships with 3.2 — statuslines work fine; stats uses features available in zsh too)
- jq — required for
statsandhistorycommands (brew install jq/apt install jq) - python3 — used during install to safely modify
settings.json(available by default on macOS and most Linux)
claudeblue uninstallThis removes ~/.claudeblue/ and the CLI symlink. You'll need to manually remove the statusLine and hooks entries from ~/.claude/settings.json.
