Claude Code Analytics

Generate HTML report of Claude Code usage from ~/.claude/history.jsonl.

Data Sources

• History: ~/.claude/history.jsonl — prompts with timestamps and project paths
• Git: Remote URLs and commit counts per project

Output

Single HTML file with terminal aesthetic:

• ASCII art header
• Summary stats (projects, prompts, commits, days)
• Project table with remote links
• ASCII bar chart

Generation Script

Run this Python script to generate the report:

import json
import os
import subprocess
from datetime import datetime, timedelta
from collections import defaultdict

def get_git_info(path):
    if not os.path.isdir(path) or not os.path.exists(os.path.join(path, '.git')):
        return None, 0
    try:
        result = subprocess.run(['git', '-C', path, 'remote', 'get-url', 'origin'],
                                capture_output=True, text=True, timeout=5)
        remote = result.stdout.strip() if result.returncode == 0 else None
        if remote:
            remote = remote.replace('git@github.com:', 'github.com/').replace('.git', '').replace('https://', '')

        week_ago = (datetime.now() - timedelta(days=7)).strftime('%Y-%m-%d')
        result = subprocess.run(['git', '-C', path, 'rev-list', '--count', f'--since={week_ago}', 'HEAD'],
                                capture_output=True, text=True, timeout=5)
        commits = int(result.stdout.strip()) if result.returncode == 0 else 0
        return remote, commits
    except:
        return None, 0

# Parse history
history = []
with open(os.path.expanduser('~/.claude/history.jsonl'), 'r') as f:
    for line in f:
        try:
            history.append(json.loads(line))
        except:
            pass

# Filter last N days (default 7)
days = 7
now = datetime.now()
cutoff = (now - timedelta(days=days)).timestamp() * 1000

projects = defaultdict(lambda: {'prompts': [], 'sessions': set()})
for entry in history:
    ts = entry.get('timestamp', 0)
    if ts >= cutoff:
        project = entry.get('project', 'unknown')
        projects[project]['prompts'].append(entry)
        projects[project]['sessions'].add(datetime.fromtimestamp(ts/1000).strftime('%Y-%m-%d'))

# Collect data
results = []
total_commits = 0
for project, data in projects.items():
    remote, commits = get_git_info(project)
    total_commits += commits
    results.append({
        'name': os.path.basename(project) or project.replace('/Users/ris/', '~/'),
        'folder': project.replace('/Users/ris/', '~/'),
        'remote': remote,
        'prompts': len(data['prompts']),
        'sessions': len(data['sessions']),
        'commits': commits
    })

results.sort(key=lambda x: -x['prompts'])
max_prompts = results[0]['prompts'] if results else 1

HTML Template

Use terminal aesthetic with:

• Monospace system fonts: 'SF Mono', 'Monaco', 'Inconsolata', monospace
• Dark background: #0d0d0d
• Muted colors: #b0b0b0 (text), #555 (dim), #4ec9b0 (cyan), #ce9178 (orange)
• ASCII box-drawing for header
• $ command --flags style section headers
• ASCII bar chart using █ characters

Bar Chart Generation

def make_bar(value, max_val, width=40):
    filled = int((value / max_val) * width)
    return '█' * filled

# Example output:
# cohorts          ████████████████████████████████████████ 194
# ai-whisper       █████████████████████████████████████▋ 183

Usage

1. User asks for analytics: "покажи статистику cc", "weekly report", "что делал за неделю"
2. Run Python script to collect data
3. Generate HTML with template
4. Save to ~/claude-analytics.html
5. Open in browser: open ~/claude-analytics.html

Customization

• Period: Change days = 7 to desired range
• Output path: Change save location
• Colors: Adjust CSS variables
• Columns: Add/remove metrics in grid
