The Agent Skills Directory

[COMMAND_EXECUTION]: The skill documents the use of the Siemens Engineering SiVArc Openness API to perform project mutations, such as sivarc.Generate(). These are standard industrial automation commands within the TIA Portal ecosystem.
[EXTERNAL_DOWNLOADS]: The skill references the Siemens.Engineering.Sivarc.dll assembly. This is a legitimate vendor-provided library required for C# Openness development and is part of the TIA Portal SiVArc installation.
[DATA_EXPOSURE]: The skill includes instructions for exporting screen layout data to YML files using the LayoutData.Export method. This is a standard feature for engineering data exchange, and the skill provides explicit warnings to validate paths and provenance for such files.
[SAFE]: The 'Safety boundary' section demonstrates security best practices by instructing the agent to never use silent fallbacks, to resolve exact selectors, and to treat engineering inputs like rule expressions and YML files as untrusted until validated.
