mitre/cti — reverse-engineered prompt

Build me a simple cyber threat intelligence data project that packages the MITRE ATT&CK and CAPEC datasets in STIX 2.0 format. I want someone to be able to clone it, browse the Enterprise, Mobile, ICS, PRE ATT&CK, and CAPEC content, and use the data in Python without needing to understand every STIX detail.

Keep the repository focused on the data, not a big web app. Add clear README guidance explaining what the datasets are, where the official MITRE pages are, and how to load the content with python stix2. Include small examples for listing techniques, attack patterns, relationships, and CAPEC entries, plus a basic sanity check script so users know the JSON loads correctly.

Please organize it cleanly, include licensing notes, and make it useful for analysts, developers, testers, and educators who want to reuse threat intelligence in their own tools. Look up current STIX and MITRE docs online if you need to.
