File contents

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.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.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 executable or modular core assembly checks.

Unless skipped, the full probe also checks:

siemens_tia_scripting importability through py or python;
tia-mcp on PATH or a TiaMcpServer dotnet global tool.

Python and MCP are client/tooling choices, not prerequisites for direct C# Openness. Use the skip switches whenever those integrations are outside scope.

Safety and evidence boundary

The probe is read-only. It must not open TIA Portal, create projects, load an Openness assembly into the current process, modify registry keys or groups, install tools, or change user configuration. Static presence, version metadata, and group membership do not prove that a project can be opened or that a credentialed/live operation will succeed.
