Use before read_file when the path is unknown; may record search history in the LINZA sidecar.read_fileRead one vault-relative Markdown file exactly as stored. Use after search or when the path is known; does not write files or sidecar state.get_statsReturn quick LINZA sidecar status: indexed file count, profiles, semantic bridges, and active profile. Use for health checks.scan_vaultRun a read-only vault diagnostic over files, links, metadata, and LINZA setup. Use at first contact or when deciding what to fix next.guide_next_stepsRead the current LINZA state and recommend the next safe onboarding/review step in plain language. This is the navigator for agents and users; it does not write files.agent_workspaceMain LINZA workflow facade. Choose one action to inspect the workspace, ingest artifacts, review/apply supervised items, explain connections, search memory, export context, or run diagnostics. Safe actions are read-only; apply actions preview by default with dry_run=true.
