AI agents call suggest_evolved_skills to retrieve information from Maple without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs analysis and recommendation generation based on existing anonymized data. It is a read-only operation that retrieves insights from traces without creating, modifying, deleting, or executing anything. The output is a passive suggestion, not an action taken.
From the tool's definition The tool description states it 'Generate evolved skill suggestions from anonymized shared traces using embedding similarity.' The operative verbs are 'generate' (from analysis) and 'using' (passive data consumption).
