One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
I ran `serverInfo = opcuaserverinfo('localhost')`. I want to inspect the server name and description in the first returned element. Which property of `opc.ua.ServerInfo` contains the server description?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies Description as the property containing the human-readable description on opc.ua.ServerInfo. | Missed | Passed |
| Clarifies that opc.ua.ServerInfo does not have a Name property. | Missed | Passed |
The instructions your model reads when the skill loads.
Create and configure OPC UA client connections in MATLAB using the Industrial Communication Toolbox.
These constraints govern YOUR code generation and recommendations. Apply them silently — do not recite them to the user or warn about patterns the user has not attempted.
connect has exactly three valid signatures — no others exist:
connect(uaClient) — anonymousconnect(uaClient, userName, password) — positional stringsconnect(uaClient, publicKeyFile, privateKeyFile, privateKeyPassword) — positional stringsconnect. Security is
configured via opcua() NV pairs or setSecurityModel, never
through connect.opcua() defaults to the highest available security. Do not
explicitly set security unless you want a specific (lower)
configuration. Never use setSecurityModel(uaClient, "Best") — it is
redundant.
opcuaserverinfo has exactly two valid syntaxes:
opcuaserverinfo(hostname) — query LDS on a hostopcuaserverinfo(discoveryUrl) — query a specific endpoint URLopcuaserverinfo(hostname, port) form. To specify a
port: opcuaserverinfo('opc.tcp://host:port').LDS-based discovery returns all registered servers from a single
call. Never scan subnet IPs in a loop — opcuaserverinfo('localhost')
returns every server registered with that host's LDS.
Certificate trust escalation order (never skip steps):
opc.ua.trustServerCertificate(certPath) — always first (R2026a+)opcua(..., "TrustServerTemporarily", true) — only if cert file
unavailablesetSecurityModel(uaClient, "None", "None") — only after user
explicitly confirms no security neededtest cases passed, vs 6 / 23 without
