Description
Adds a new
tm7-threat-modelskill that generates valid Microsoft Threat Modeling Tool (.tm7) files..tm7files use the WCFDataContractSerializerformat (not generic XML); the Threat Modeling Tool refuses to open files that use a plain-XML structure. This skill documents the exact root element, namespace prefixes, stencil/data-flow/threat serialization, and a checklist of common mistakes that corrupt.tm7files. It bundles a validatedexample-minimal.tm7reference (well-formed, no<?xml?>declaration).This is a clean re-submission of #1660 (which was closed only because it targeted
mainand had a polluted, auto-regenerated diff). This PR targetsstagedand changes only the new skill folder plus its single generated row indocs/README.skills.md.Type of Contribution
