README

Spend Optimizer

Audit subscriptions and optimize credit card rewards in one workflow. Analyzes your transaction CSVs to find recurring charges, shows which card each expense should be on, and generates interactive HTML reports.

What It Does

  1. Finds subscriptions - Scans months of transactions to identify recurring charges
  2. Optimizes card placement - Shows which card each charge is on vs. which card maximizes rewards
  3. Flags missed credits - Alerts you when you're paying for something that's FREE on another card (e.g., Disney+ on Amex Platinum, DoorDash on Sapphire Reserve)
  4. Detects price increases - Catches when services quietly raised prices on you
  5. Tracks annual subscriptions - Flags yearly charges with estimated renewal dates so you don't forget
  6. Monitors category caps - Tracks progress toward $150K Amex/Chase bonus limits with overflow suggestions
  7. Tracks decisions - Keep, cancel, investigate, or dispute each subscription
  8. Calculates savings - Shows potential annual rewards and savings from cancellations

Installation

Copy the `spend-optimizer` folder to your Claude Code skills directory:

# macOS/Linux
