Security checks for vulnerabilities and agentic risk

Overview

The skill is a clearly scoped Instagram hashtag monitoring helper that uses Apify with disclosed billing, approval, and data-sharing controls.

Install only if you are comfortable using a paid Apify account for Instagram campaign monitoring. Before each run, check the hashtags, scan window, charge cap, and any webhook destination, because campaign inputs and matching public post data will be processed by Apify and may be forwarded to an approved webhook.
