Arccos Golf Performance Analyzer

Name: Arccos Golf
Author: pfrederiksen

Fetches live data from the Arccos Golf API and generates performance analysis: strokes gained, club distances, scoring, putting, pace of play, and recent rounds.

⚠️ Privacy & Security Notice

This skill makes authenticated network requests to Arccos Golf API servers using your account credentials:

Credentials: Your Arccos email and password are used to authenticate. A session token is cached at ~/.arccos_creds.json (mode 0600, readable only by your user).
Network: The script calls authentication.arccosgolf.com (login) and api.arccosgolf.com (data). No other endpoints are contacted.
No data leaves your machine beyond the API calls needed to fetch your own golf data.
External dependency: Requires the arccos library from github.com/pfrederiksen/arccos-api (MIT licensed, authored by the same user who published this skill).

Review the arccos library source before installing if you have concerns: <https://github.com/pfrederiksen/arccos-api>

Prerequisites
