Claude Skills
The open format is called Agent Skills and works in Claude Code, Codex, Cursor and other agents — most people know it as Claude Skills.
Every Agent Skill we could find on GitHub, deduplicated by content. 86 696 files from 2 113 authors, of which 68 413 are unique — the rest is the same skill repackaged into someone else's repository. For each one: what it weighs in tokens, whether it ships runnable scripts, and which MCP servers it needs.
> creating Add-In C# projects, adding Add-In templates, compiling and debugging Add-Ins, converting Add-Ins from older TIA Portal versions and configuring Add-In project parameters.
> C# Openness implementation of import/export and round-trip engineering.
> Standalone skill for multi-perspective PLC code security and quality analysis. "code review", "check this code", "is this safe", "find issues" when combined with PLC, SCL, ST, LAD, FBD, Structured Text, or block context. Also triggers when the user pastes PLC code and asks for feedback, or uploads exported SimaticML XML files. This skill is independent of tia-openness-roadmap — it does not perform engineering automation. It analyzes code that has already been exported, pasted, or is accessible via the TIA Portal MCP server.
> TIA Portal Multiuser Engineering operations. Use for managing server projects, local sessions, and multiuser commissioning workflows.
> C# Openness implementation of HMI engineering.
Manual prerequisite probe for TIA Portal, Openness, Python TIA Scripting, and TIA MCP.
Internal reference skill — do NOT load directly from user queries.
> C# Openness implementation of topology and low-level network engineering.
> Entry point for ALL TIA Portal engineering automation tasks. Always load this skill FIRST when the user mentions TIA Portal, TIA Openness, TIA Scripting, Siemens PLC, Siemens HMI, TIA Portal Add-In, or any automation/engineering task targeting TIA Portal. This skill routes to the correct domain skill and selects MCP, Python, or C# implementation.
Reference routed skill. Do NOT load directly unless user says so.
> SIMATIC Drive Controller, PROFIdrive integrated properties, drive telegrams, and integrated drive configuration. Always uses C# TIA Portal Openness.
> Use when the TIA Portal MCP server is available for focused, guarded project reads and writes. Use TIA Openness skills for complex multi-step automation.
C# Openness implementation of project and portal lifecycle.
C# Openness implementation of PLC software engineering.
> TIA Portal Teamcenter Integration operations. Use for managing Teamcenter storage and interacting with Teamcenter managed projects.
> TIA Portal TestSuite and Application Test operations. Use for managing test sets, application tests, style guide rules, and automated system testing workflows.
Convert arXiv papers to Markdown documentation. Fetches available materials from arXiv (LaTeX source when available + PDF), converts LaTeX to Markdown via pandoc (happy path). PDF-only papers get a naive single-column fallback — use the specialized PDF scripts for better results.
Look up arXiv paper metadata via the arXiv API. Use when you need to get a journal DOI from an arXiv ID (for OpenAlex integration), or find an arXiv ID from a title/keyword search (for arxiv-doc-builder). Requires the `arxiv` Python package.
