Each tool has a clearly distinct purpose with no overlap: check_inbox lists emails, read_email reads a specific email, register_agent sets up the agent, reply_to_email replies within a thread, and send_email sends new emails. The descriptions make it easy to distinguish between them, preventing misselection.

All tools follow a consistent verb_noun pattern with snake_case (e.g., check_inbox, read_email, register_agent). The naming is predictable and readable throughout, with no deviations or mixed conventions.

With 5 tools, the server is well-scoped for email management on Envoi.work. Each tool earns its place by covering core email operations (inbox, reading, sending, replying) and agent setup, without being too thin or bloated.

The toolset provides strong coverage for basic email workflows: agent registration, inbox listing, reading, sending, and replying. A minor gap is the lack of tools for managing emails (e.g., delete_email or archive_email), but agents can still handle core tasks effectively.
