How does this skill handle price fluctuations?

The skill includes a 5% amount tolerance rule, allowing it to correctly identify subscriptions even when taxes, currency conversions, or minor price adjustments change the transaction total.

What is the minimum data required to detect a subscription?

Generally, the skill requires at least three occurrences of a transaction matching the same merchant and frequency pattern to confirm a subscription.

Can I manually exclude a merchant that looks like a subscription?

Yes. The skill checks a 'learnings/subscriptions.md' file before processing. You can add any merchant to the 'Not Subscriptions' list to prevent them from being flagged.

Does it support annual subscriptions?

Yes, it detects annual intervals and can even proactively flag known annual services (like Adobe or Amazon Prime) as subscriptions with fewer than three occurrences if they match known patterns.

Productivity & Workflow

Identifies recurring charges and subscriptions from transaction history using pattern matching and frequency analysis.

The Subscription Detection skill enables Claude to intelligently analyze financial transaction data to isolate recurring subscriptions. By applying a rigorous five-point criteria check—including merchant normalization, frequency consistency, and a 5% amount tolerance—the skill distinguishes between regular service payments and one-time purchases. It features a built-in learning mechanism that references user-defined files to avoid false positives and tracks subscription statuses such as active, paused, or cancelled, while automatically calculating projected annual costs for better financial oversight.
