An agent can browse the node tree, search for tags like "Flow" and read live values, which is the slow part of a brownfield assessment. It ships with a water treatment plant simulator to practice on.
For SCADA and integration engineers: map what a server exposes in minutes before you build anything on top of it.
Open-source Python maintained at TU Berlin that runs dispatch and capacity planning, with more than 2,200 GitHub stars. Because it is plain Python, an agent can drive it to test how much battery a site really needs.
For power and data center developers: size onsite generation and storage with the same tool grid planners use.
solidSF open-sourced solidcv-cad, which takes video in and puts out STEP, GLB or IGES files for single parts and full assemblies. A sister repo pulls a simulation model from real life. Reverse engineering a worn part could start with a phone video.
The skills cover IEC 61131-3 PLC work, preliminary IEC 62443 OT security assessments, paperwork for authorized OT testing and IEC 61000 EMC planning. They run locally with no network access, and the author says plainly that output is guidance, not compliance.
For controls and OT security engineers: a first draft of the review and gap assessment work, to be checked by a qualified engineer.
