AI agents call preview_inbox_intake to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays intake data (GitHub issues, CI logs, feedback, etc.) with optional deduplication and redaction applied to the output. These are read-only operations that query and format existing data without creating, modifying, deleting, or executing code. The 'preview' framing and mention of 'redaction' (filtering display output) confirm no side effects beyond data retrieval.
From the tool's definition Tool name contains 'preview' and description states 'Preview local inbox intake' with operations limited to 'dedupe and redaction' - no modification or execution of external systems described.
