A read-only diagnostic check for Siemens TIA Portal V21 and its Openness automation interface, with optional checks for Python scripting and an MCP connection.

Use it when diagnosing or verifying a TIA Portal automation setup and when you need pass, warning or failure results with remediation guidance.

It shows whether the required local software and integration prerequisites are present before automation work begins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.00558
Opus 5	$0.00018	$0.00279
Sonnet 5	$0.00007	$0.00112
Haiku 4.5	$0.00004	$0.00056

Security

Grade A, and why

tia-doctor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (probe.ps1), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tia-doctor is a skill published in the GitHub repository Czarnak/totally-integrated-claude (57 stars, last pushed 27d ago), licensed MIT. It adds 36 tokens to every session and 558 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
