Call this at the end of a session or when the user asks for a performance review.
AI agents call carapace_review to retrieve information from Carapace MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reviews and reports on session performance and security metrics. It retrieves logged data and provides insights, but does not create, modify, delete, execute external actions, or move money. The 'review' operation is fundamentally a read-only inspection of existing session records, making it a Read category tool with low severity since misuse would only expose information already logged by the agent itself.
From the tool's definition Tool name 'carapace_review' and description 'Call this at the end of a session or when the user asks for a performance review' indicate retrieval and reporting of session data with no modifications.
