AI agents call kicad.search_symbols to retrieve information from Eda without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name contains 'search', which is a read operation. In KiCad context, searching symbols means querying the symbol library to find components, which has no side effects. However, the description is empty, so confidence is reduced. The 'search' prefix is a strong signal for a Read classification with low severity.
From the tool's definition Tool name: kicad.search_symbols — 'search' strongly implies a read/query operation
