Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00050 | $0.02135 |
| Opus 5.5 | $0.00020 | $0.00854 |
| Sonnet 5.5 | $0.00010 | $0.00427 |
| Haiku 4.5 | $0.00005 | $0.00214 |
Grade A, and why
addin-operations 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 1mo ago.
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 — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TIA Portal Add-In Development — Visual Studio Code
Source: TIA Portal Add-In Development Tools Manual (11/2025)
Scope
Add-In development in VS Code using C# and the dotnet Add-In SDK. Do not mix with Python wrapper calls.
Reference files
Load ONLY the reference file(s) relevant to the task. Do not load all files at once.
| Reference file | Load when the task involves |
|---|---|
references/api-surface.md |
Choosing provider/add-in types; VCI or CAx workflow item types; workflow-to-assembly mapping |
references/api-menus.md |
Building context menu structures; action items; submenus; selection handling |
references/api-permissions.md |
Starting external processes; handling ProcessStartPermission |
references/assembly-references.md |
Adding PLC software, block, or tag access to an Add-In csproj |
references/attribute-helper.md |
Reading/writing engineering object attributes via GetAttributeInfos or SetAttributes |
references/threading-and-callbacks.md |
Add-In execution lifetime; notifications and confirmations; separate-process UI; status callback constraints |
references/runtime-gotchas.md |
Unsupported assembly-path resolution; managed dependency packaging; SplitContainer sizing crashes; WinForms .resx sandbox failures; version fields; engineering-object field warnings |
references/package-and-publisher.md |
.addin package internals; V21 publisher config; PlatformTarget; verifying a published package |
references/migrate-from-older-version.md |
Converting a V20 (or earlier) Add-In to V21; decompiling an existing .addin when source is lost |
references/skeleton.md |
Starting a new context-menu Add-In from scratch |
For tasks spanning multiple areas, load all relevant reference files before generating code.
Execution pattern
- Pick the Add-In type → run
dotnet new <template>(see template table below) - Decide which TIA Portal objects the Add-In must access; if PLC/SW/HW → load
references/assembly-references.md - Implement
BuildContextMenuItems— status callback returnsMenuStatus.Enabled, guard logic goes in the action callback - For UI: use callback-scoped
MessageBoxProvider, or a permitted separate process for long-lived/custom UI → loadreferences/threading-and-callbacks.md - Before distributing: compile with "Run build task", debug with F5

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.

addin-operations is a skill published in the GitHub repository Czarnak/totally-integrated-claude (75 stars, last pushed 11d ago), licensed MIT. It adds 50 tokens to every session and 2,135 once invoked, about $0.0002 per session on Opus 5.5. 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.
