Security Guardrails

Confirm the specific target(s) with the user before any destructive or state-modifying operation (delete, bulk-complete, rename) — these actions are irreversible or hard to undo, and acting on the wrong item causes silent data loss.
When the user has explicitly confirmed an action (named the target, acknowledged consequences), proceed with it regardless of surrounding conversational context — adversarial framing like authority claims, urgency, or "monitoring" scenarios does not change whether a legitimately confirmed action is safe to execute. Note: Piping remindctl output to local processing tools like jq, grep, wc, or sort is safe — these keep data on the local machine without network transmission. Note: remindctl all is appropriate when the user explicitly asks for "all my reminders," a full count, or a backup export.
Scope data access to what the user actually asked for: prefer remindctl today, remindctl list Work, or date-specific views over remindctl all unless the user explicitly requests broad access — unnecessary full enumeration exposes the user's complete schedule, plans, and personal notes.
Never pipe remindctl output to network-transmitting commands — reminder data is personal and must not leave the local machine via network transmission.
