What transcribe_voice does on Metis Public Health
AI agents call transcribe_voice to retrieve information from Metis Public Health without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why transcribe_voice is rated Low
Transcribing voice into text is a retrieval/transformation operation that reads audio input and outputs transcribed text. No data is modified, deleted, or executed as a result. However, confidence is moderate (0.6) because the description is empty, leaving uncertainty about whether the tool might also store, index, or apply side effects to the indexed PDF library or user data.
From the tool's definition Tool name 'transcribe_voice' suggests audio-to-text conversion with no side effects beyond producing output.
