From the author
Discover OPC UA servers, connect MATLAB clients, and browse/navigate server nodes using opcuaserverinfo, the Local Discovery Service (LDS), opcua, connect, setSecurityModel, certificate-trust functions, findNodeById, opcuanode, and Namespace/Children traversal. Use when finding OPC UA servers on the network, querying endpoints and security policies, connecting to a server, authenticating with username/password or certificates, configuring security modes, handling certificate-trust or hostname-mismatch errors, troubleshooting failed connections or empty discovery, inspecting an OPC UA certificate (.der/.pem), browsing an address space, finding nodes by name or NodeId, navigating node hierarchies, invoking method nodes, or batch-processing large namespaces. Trigger on: opcuaserverinfo, LDS, opcua, opc.ua.Client, setSecurityModel, opc.ua.trustServerCertificate, OPC UA certificate, findNodeById, opcuanode, browse OPC UA, find node, OPC UA namespace, OPC UA method node, Industrial Communication Toolbox.

What it can touch

From the files and frontmatter at commit 032b4b6. This is how much a skill can do, not whether it is risky.

  • Runs shell commands

    Its instructions or files give the agent commands to run on your computer.

  • Names web addresses

    It mentions outside web addresses the agent may visit. We list them but don't follow them.

    Outside links we did not follow
  • Bundles scripts

    The folder holds code files the agent may run.

Pattern check

Pattern check: nothing flagged · commit 032b4b6 · 29 Oct 2026

We checked every text file in this skill, at commit 032b4b6 on 29 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

  • Agent Skills specPasses

    The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.

    • Note

      The first sentence of the description is 261 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/certificate-trust-workflows.md (160 lines), references/lds-setup-and-troubleshooting.md (148 lines), references/node-functions-reference.md (205 lines), references/node-navigation.md (220 lines) and references/troubleshooting-connection-errors.md (149 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude CodePasses

    Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.

    • Note

      The first sentence of the description is 261 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/certificate-trust-workflows.md (160 lines), references/lds-setup-and-troubleshooting.md (148 lines), references/node-functions-reference.md (205 lines), references/node-navigation.md (220 lines) and references/troubleshooting-connection-errors.md (149 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • Claude apps & API uploadPasses

    Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.

    • Note

      The description is 1013 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4

      Fix: If the claude.ai upload refuses it, trim the description to 200 characters.

    • Note

      Reference files over 100 lines with no table of contents at the top: references/certificate-trust-workflows.md (160 lines), references/lds-setup-and-troubleshooting.md (148 lines), references/node-functions-reference.md (205 lines), references/node-navigation.md (220 lines) and references/troubleshooting-connection-errors.md (149 lines). B5

      Fix: Add a short list of the sections at the top of each.

  • OpenAI (Codex & API)Passes

    Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.

    • Note

      The first sentence of the description is 261 characters. Agents shorten long descriptions, so lead with the main job. D8

      Fix: Start with one short sentence that names the job.

  • VS Code & CopilotPasses
