CodeBurn

Skill by ara.so — Daily 2026 Skills collection.

CodeBurn is an interactive TUI dashboard that reads Claude Code session transcripts directly from disk (~/.claude/projects/) and visualizes token usage, costs, and task breakdowns by project, model, activity type, MCP server, and tool. No API keys, no proxy — pure local file analysis.

Install

npm install -g codeburn
# or run without installing
npx codeburn

Requirements: Node.js 20+, Claude Code installed (session data at ~/.claude/projects/)

Key Commands

# Interactive TUI dashboard (default: last 7 days)
codeburn

# Time period shortcuts
codeburn today
codeburn month
codeburn report -p month      # explicit period flag

# Compact one-liner summary
codeburn status
codeburn status --format json

# Export data
codeburn export               # CSV: today, 7d, 30d
codeburn export -f json       # JSON export

# macOS menu bar widget (requires SwiftBar)
codeburn install-menubar
codeburn uninstall-menubar

What CodeBurn Tracks

13 Task Categories (deterministic, no LLM calls)

One-Shot Rate

For edit-heavy categories, CodeBurn detects Edit → Bash → Edit retry cycles. The 1-shot rate shows what percentage of edit turns succeeded without retries. 90% means the AI got it right first try 9/10 times.

Pricing

Fetched from LiteLLM model prices, auto-cached 24h at ~/.cache/codeburn/. Covers input, output, cache write, cache read, and web search costs. Falls back to hardcoded prices if fetch fails.

Data Source

Claude Code stores session transcripts as JSONL:

~/.claude/projects/<sanitized-path>/<session-id>.jsonl

Each assistant entry contains: model name, token usage (input/output/cache_read/cache_write), tool_use blocks, timestamps. CodeBurn deduplicates by API message ID to prevent double-counting across sessions.

macOS Menu Bar Setup

# 1. Install SwiftBar
brew install --cask swiftbar

# 2. Install the CodeBurn plugin
codeburn install-menubar

# 3. Launch SwiftBar — CodeBurn flame icon appears in menu bar
# Refreshes every 5 minutes, shows today's cost + breakdown dropdown

To remove:

codeburn uninstall-menubar

Export Examples

# Export CSV (three sheets: today, 7d, 30d)
codeburn export
# Output: codeburn-export-2026-04-14.csv

# Export JSON
codeburn export -f json
# Output: codeburn-export-2026-04-14.json

Programmatic Usage (TypeScript)

If you want to integrate CodeBurn's parsing logic into your own scripts:

import { parseSessions } from 'codeburn/parser';
import { calculateCost } from 'codeburn/models';
import { classifyTurn } from 'codeburn/classifier';

// Parse all sessions for a date range
const sessions = await parseSessions({
  startDate: new Date('2026-04-01'),
  endDate: new Date('2026-04-14'),
});

// Sessions are deduplicated by API message ID
for (const turn of sessions.turns) {
  const category = classifyTurn(turn);
  const cost = await calculateCost(turn.model, turn.usage);
  console.log(`${category}: $${cost.toFixed(4)}`);
}

// Get a status summary programmatically
import { getStatus } from 'codeburn/format';

const status = await getStatus();
console.log(status);
// → "🔥 Today: $1.42 (284k tokens) | Month: $18.30 (3.6M tokens)"

// JSON format for scripting
const statusJson = await getStatus({ format: 'json' });
const data = JSON.parse(statusJson);
// { today: { cost: 1.42, tokens: 284000 }, month: { cost: 18.30, tokens: 3600000 } }

Common Patterns

Daily Cost Check in CI/Shell Scripts

#!/bin/bash
# Add to .zshrc or run in CI to log daily AI spend
SPEND=$(codeburn status --format json | jq '.today.cost')
echo "Today's Claude spend: \$$SPEND"

# Alert if over threshold
if (( $(echo "$SPEND > 5.00" | bc -l) )); then
  echo "⚠️  High AI spend today: \$$SPEND"
fi

Export and Analyze with jq

# Export JSON and analyze by model
codeburn export -f json | jq '.periods["7d"].by_model'

# Find most expensive project this month
codeburn export -f json | jq '
  .periods["30d"].by_project
  | to_entries
  | sort_by(-.value)
  | .[0]
'

Automate Weekly Reports

#!/bin/bash
# weekly-ai-report.sh — run via cron on Mondays
OUTPUT_DIR="$HOME/ai-cost-reports"
mkdir -p "$OUTPUT_DIR"

DATE=$(date +%Y-%m-%d)
codeburn export -f json > "$OUTPUT_DIR/week-$DATE.json"
codeburn status >> "$OUTPUT_DIR/history.log"
echo "[$DATE] Report saved to $OUTPUT_DIR/week-$DATE.json"

Troubleshooting

No data shown / "No sessions found"

# Verify Claude Code session files exist
ls ~/.claude/projects/

# Check a specific project's sessions
ls ~/.claude/projects/<project-name>/
# Should see *.jsonl files

# Confirm Node version is 20+
node --version

Pricing fetch fails / shows $0.00

# Clear the price cache and retry
rm -rf ~/.cache/codeburn/

# CodeBurn falls back to hardcoded prices automatically
# Run again — it will re-fetch from LiteLLM
codeburn today

Menu bar widget not updating

# Reinstall the plugin
codeburn uninstall-menubar
codeburn install-menubar

# Ensure SwiftBar is running and plugin directory is set
# SwiftBar → Preferences → Plugin folder should point to ~/Library/Application Support/SwiftBar/Plugins/

Double-counted costs

CodeBurn deduplicates by API message ID automatically. If you see unexpectedly high numbers, check for duplicate JSONL files:

# List all session files sorted by size
find ~/.claude/projects/ -name "*.jsonl" | xargs wc -l | sort -rn | head -20

TUI rendering issues

# Ensure terminal supports 256 colors
echo $TERM
# Should be xterm-256color or similar

# Force color mode
COLORTERM=truecolor codeburn
