  "jsonrpc": "2.0",

## Why update_reminder is rated Medium

This tool modifies existing reminders reversibly (updates fields without deletion). It does not delete data (making it not Destructive), execute arbitrary code (not Execute), move money (not Financial), or trigger external operations (not Execute). The blast radius is medium because misuse could alter important user reminders, but changes are reversible and limited to the reminder system.

From the tool's own definition: "Tool description states 'Update fields of an existing reminder in Apple Reminders — a write to user data; only the fields you pass change.' The word 'Update' and explicit mention of 'write to user data' confirm Write category."

## Use case

AI agents use update_reminder to create or update resources in Iconnect, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Iconnect environment.

## Recommended policy (PolicyLayer)
