Offline AgentMail Draft Scaffold With Ambiguous Nearby Credential

Problem/Feature Description

You are setting up the smallest truthful Node.js scaffold for an AgentMail draft workflow.

A teammate says there is already an environment variable named AGENTMAIL_KEY on the machine, but the workflow guidance you are following says the AgentMail SDK requires AGENTMAIL_API_KEY exactly unless there is explicit proof that another variable name is interchangeable.

The goal is to write a script that is honest about this boundary:

• require AGENTMAIL_API_KEY exactly for the real workflow
• if AGENTMAIL_KEY is present nearby, treat it only as an unverified alias and warn about it
• do not silently fall back to AGENTMAIL_KEY
• show the exact draft create/send call shapes the current SDK expects
• keep this script offline / dry-run friendly rather than pretending a live send succeeded

Output Specification

Write a single Node script named draft_scaffold.js that:

1. Imports the official AgentMail SDK from agentmail
2. Reads AGENTMAIL_API_KEY from the environment and exits with a clear non-zero failure if it is missing
3. If AGENTMAIL_KEY is present, prints a warning that it is only a nearby unverified alias and is not being used automatically
4. Initializes the AgentMail client with AGENTMAIL_API_KEY
5. Shows the exact current draft workflow call shapes:
   • client.inboxes.drafts.create(inboxId, request)
   • client.inboxes.drafts.send(inboxId, draft.draftId)
6. Stays truthful about being an offline scaffold / dry run instead of claiming that a draft was really created or sent

Use these example values inside the scaffold:

• inboxId = "agent@example.agentmail.to"
• recipient = "macey@example.com"
• subject = "Draft pending approval"
• text = "Hello from an offline AgentMail scaffold."

Do not write tests or extra files.
