# Email & Calendar Scopes — the read-write boundary matters

Giving an agent access to email is the fastest way to unlock high-value use cases — and the fastest way to cause a catastrophe. Scope discipline is the whole game.

## The threat

An agent with Gmail 'modify' scope can send, delete, archive, and move emails. A single prompt injection in an email body can exfiltrate data, delete evidence, or impersonate you. The default OAuth scopes most people accept are far broader than needed.

## What to do about it

1. ### 1. Read-only by default

 Triage, summarization, search — all work with read-only scope. Most use cases don't need write. Start read-only; escalate only when required.
2. ### 2. Draft-only for sending

 Agent writes to drafts folder. You review and send. Never grant send scope without this gate.
3. ### 3. Never grant delete scope

 Deleted emails can be forensic evidence during an incident. An agent with delete scope can destroy its own tracks. Archive is always enough.
4. ### 4. Use labels for agent actions

 Every email the agent touches gets a label. You can audit or undo wholesale.
5. ### 5. Review OAuth grants monthly

 Google, Microsoft, Apple all have an 'apps with access' page. Anything you don't actively use → revoke.

## Real-world examples

- An email-triage agent with full modify scope encountered a prompt injection in a newsletter and archived 800 emails matching 'invoice' into trash.
- An agent with send scope auto-replied to a phishing email with internal scheduling info, confirming the target was human and active.

Examples are illustrative, composited from public incident reports and community posts.
