100x-dev

Track your AI-powered velocity.

---

The Problem

Everyone claims AI makes them 10x. Nobody has the data. 100x-dev tracks your git history, separates AI commits from human commits, and gives you a real multiplier. Not vibes — math.

---

Quick Start

npx 100x-dev start
# ... ship code with Claude ...
npx 100x-dev stop

No install needed. Just run in any git repo.

Example Output

  100x-dev — AI velocity tracker
  ─────────────────────────────
  Session complete

  47.3x multiplier

  AI    [████████████████████████████░░] 97.9%
  Human [░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░]  2.1%

  ─────────────────────────────
  Duration     2h 14m
  Commits      38 total  36 AI  2 human
  Lines +      +4,832
  Lines −      -1,204
  AI wrote     5,909 lines
  You wrote    127 lines

  🔥 Legendary session. That's 100x energy.

Features

• Detects AI commits via Claude Code co-author tags, [AI] / [Claude] prefixes, and 🤖 annotations
• Calculates a real multiplier: totalLines / humanLines
• Lifetime stats across all sessions
• Personal leaderboard of your best sessions
• SVG badge generator — drop your multiplier into any README
• Scorecard card SVG for sharing
• Local-only storage (~/.100x-dev/sessions.json) — zero telemetry

---

How It Works

1. 100x-dev start — records the current git HEAD as session baseline
2. You commit code (Claude Code auto-tags its commits with Co-Authored-By)
3. 100x-dev stop — walks commits since baseline, classifies each as AI or human via pattern matching, calculates line counts and multiplier, renders the session card

Detection Logic

A commit is classified as AI-written if the message or body matches any of:

Pattern	Example
Co-Authored-By: Claude	Added automatically by Claude Code
🤖 in message	Manual tag
[AI] or [Claude]	Manual tag
Generated with [Claude	Claude Code footer
noreply@anthropic.com	Anthropic co-author email

Multiplier formula:

multiplier = totalLines / humanLines
