Context Cost

~646Tokens (tool definitions)
~3.1 KBTypical response size
Moderate attention impact (0.50% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢qt_documentation_search(filter, intent, keywords, max_results, module, ...)

Call qt_documentation_search when: (a) you're about to claim a signal/slot/property/default exists, (b) the API is in Qt 6.7+ or a non-core module (MQTT, OPC UA, Network Auth, etc), (c) the user used the words 'docs', 'official', 'verify', or 'check'. Skip when: the question is about basic QString/QObject/signal-slot syntax.
