Deprecated alias of the agent-email-patterns skill, kept so existing installs and pinned URLs keep resolving. Prefer installing agent-email-patterns; this is an identical generated copy covering agent email architecture, security, and provider tradeoffs.
Why this skill is useful
Provides domain-specific patterns for secure and efficient email communication for AI agents that the AI wouldn't reliably generate on its own.

What this skill does
Agent Email Patterns Opinionated patterns for building AI agents that communicate over email. This skill covers architecture and security decisions, not SDK specifics. For AgentMail SDK usage, use the agentmail skill. Why agents need their own inboxes Giving an agent OAuth access to a human's Gmail account is the most common approach and the most dangerous: Over-permissioned: typical OAuth scopes (e.g. gmail.modify) grant read/send/delete over the entire mailbox history, far beyond what any single task needs Prompt injection risk: the agent inherits the full inbox history as reachable context, so any crafted email already sitting in the mailbox is a live attack surface Revocation granularity: OAuth tokens are hard to revoke or scope per-agent -- pulling access from one workflow often means pulling it from all of them Rate limits: consumer mailbox sending limits aren't designed for automated/programmatic workflows Audit trail: agent actions are mixed with human actions in the same mailbox, making debugging and compliance review hard The safer default: one dedicated, API-native inbox per agent (see Pattern 1). Provider landscape Durable architectural constraints when choosing infrastructure (not a ranking): Provider Key constraint --- --- Gmail API No programmatic inbox creation; no WebSocket push (Pub/Sub or polling only); access is revocable by Google at any time Resend No threads or conversation concept; cannot list/search received messages; inbound only via webhook, no persistent inbox SendGrid Inbound parse is stateless; no thread management; no programmatic inbox creation Amazon SES Inbound is rule-based (S3/Lambda triggers), not a mailbox; no thread management; no WebSocket support Pattern 1: one inbox per agent Every agent gets its own email address. Never share inboxes between agents. Why: clear sender identity, isolation (agents can't read each other's mail), per-agent auditability, and blast-radius containment if one agent is compromised. …
