# tia-doctor Use this skill only when the user explicitly asks to diagnose, verify, or debug the local TIA Portal automation environment. ## Run Full probe: ```powershell powershell.exe -NoProfile -ExecutionPolicy Bypass -File skills\tia-doctor\probe.ps1 -RequiredMajorVersion 21 ``` V21 C# Openness core only (the audit mode while Python and MCP are intentionally out of scope): ```powershell powershell.exe -NoProfile -ExecutionPolicy Bypass -File skills\tia-doctor\probe.ps1 -RequiredMajorVersion 21 -SkipPython -SkipMcp ``` Add `-Json` to either command for machine-readable output. ## Interpret results - `pass`: the scoped prerequisite is present and usable by the static probe. - `warn`: an optional probe could not be completed or a non-required item is missing. - `fail`: a required prerequisite for the requested scope is missing or unusable. Report missing items using the probe's remediation text. Do not invent an installation command when the result already supplies one. ## V21 checks The core probe verifies: - the exact TIA Portal V21 executable under a common Siemens installation path; - the V21 modular Public API path (`PublicAPI\V21\net48`); - the required modular core `Siemens.Engineering.Base.dll`, plus file/assembly version evidence and the installed optional `Siemens.Engineering.*` modules; - current Windows-user membership in the `Siemens TIA Openness` local group. Registry entries are supplemental evidence only; they do not replace the exact Portal e...
