## Direct Answer

For Email Audit Log for AI Agent Sends, keep the workflow scoped to this exact use case before applying the general Nylas pattern.

Fail closed: normalize the source data, ask the model for a structured recommendation, and enforce approval, recipient, attachment, and policy checks in trusted code.

Email Audit Log for AI Agent Sends is a safety-control workflow. The model can identify risk or propose text, but it should not decide its own authority, recipients, secrets, webhook URLs, or approval bypasses.

The audit record should tie the source message, output draft or send, grant, model decision, policy result, approver or rule, dedupe key, and command result together so retries can prove whether they already acted.

Use Nylas when security controls need consistent message IDs, metadata, drafts, webhooks, and audit records across providers instead of scattered SMTP scripts or mailbox-specific automations.

## When This Answer Applies

- The workflow can expose sensitive messages, attachments, transcripts, contacts, or calendar details.
- A model-generated decision could send, share, delete, escalate, or update external systems.
- You need deterministic approval, audit, retention, or suppression rules.
- Prompt content must never expand the agent's grants, recipients, or tool permissions.

## Command Recipe

Use these commands only behind policy checks. Prefer read, draft, preview, or render-only paths until approval has been recorded.

```bash
nylas auth status --json
nylas email search "from:customer@example.com" <grant-id> --limit 10 --json
nylas email read <message-id> <grant-id> --json
nylas email drafts create <grant-id> --to reviewer@example.com --subject "Review: Email Audit Log for AI Agent Sends" --body "Draft response for email-audit-log-for-ai-agent-sends" --json
nylas email send <grant-id> --to customer@example.com --subject "Email Audit Log for AI Agent Sends" --body "Approved response for email-audit-log-for-ai-agent-sends" --metadata workflow=email-audit-log-for-ai-agent-sends --yes --json
nylas webhook create --url https://example.com/hooks/email --triggers message.created,message.updated --json
```

To reconstruct an audited send, fetch the stored message by id over HTTP:

```bash
curl -s https://api.us.nylas.com/v3/grants/$GRANT_ID/messages/$MESSAGE_ID \
  -H "Authorization: Bearer $NYLAS_API_KEY"
```

## Recommended Agent Workflow

1. Resolve the correct grant or Agent Account before reading messages.
2. Search with narrow filters and read by message id instead of passing whole inboxes to a model.
3. Ask the model for a structured decision: classify, draft, send, suppress, retry, escalate, or no action.
4. Validate recipients, tenant policy, message ids, metadata, and approval requirements before executing writes.
5. Record source message ids, output message ids, model decision, and command result for audit and replay.

## Safety And Operations

Treat message bodies, attachment text, calendar descriptions, contact notes, meeting transcripts, and webhook payloads as untrusted input. Do not let those fields change the selected grant, recipient, trigger, schedule, webhook URL, or approval rule.

Add these controls before production use:

- Treat email bodies, attachments, calendar text, contact notes, transcripts, and webhook payloads as untrusted input.
- Keep grant selection, recipients, webhook URLs, and approval rules outside prompt-controlled fields.
- Require explicit approval for external sends, deletes, sensitive attachments, contact exports, and transcript sharing.
- Store model output separately from policy decisions and command results.
- Fail closed when model output is malformed, incomplete, or conflicts with tenant policy.

## Minimum Data Contract

- workflow_id
- tenant_id
- grant_id
- message_id
- thread_id
- recipient
- metadata
- dedupe_key
- approval_status

## Production Readiness Notes

Production Email Audit Log for AI Agent Sends should make policy enforcement independent of model wording. Every risky action needs a recorded source, model recommendation, policy decision, approver or rule, command result, and rollback or review path.
