mail-operations Skill

L0: One-line Summary

Send and receive email, search, manage labels, and run automation rules via a local REST API; supports Gmail / Outlook / IMAP.

L1: Overview and Use Cases

Capability

mail-operations is a Procedural Skill that operates email systems through DesireCore's local REST API. It supports three mailbox types—Gmail (OAuth2), Outlook (MSAL), and IMAP/SMTP (QQ, 163, Yahoo, etc.)—covering send/receive, search, label management, attachment download, draft management, and automation rules.

Use Cases

• The user wants to view the inbox, send, or reply to email
• The user wants to search for specific emails or manage email labels/categories
• The user wants to download attachments or manage drafts
• The user wants to set up auto-reply rules or trigger an Agent to handle email

Core Value

• Unified interface: three mailbox types are operated through a unified API, lowering complexity
• Local and secure: all operations go through the local API; no need to expose credentials
• Smart integration: supports automation rules and Agent-based email handling

L2: Detailed Specification

API Basics

• Base URL: https://127.0.0.1:62000/api
• Authentication: none required (local service)
• Content-Type: application/json
• SSL: use curl -k to skip self-signed certificate verification
• Response format: success {"code": 1, "msg": "Success", "result": ...}, failure {"code": 0, "msg": "error message"}

---

Mandatory Behavior Rules

The following rules have the highest priority and must be obeyed on every operation.

Rule 1: Operate Only Through the Local API

All email operations must and may only be done through https://127.0.0.1:62000. Never call an external email client or browser.

If the API returns 401 (authorization expired):

1. Tell the user the account's authorization has expired
2. Prompt the user to re-authorize in DesireCore
3. Gmail: POST /api/gmail/auth/initiate?loginHint={email}, Outlook: POST /api/outlook/auth/initiate

Rule 2: Confirm the Account Before Operating

Before performing any operation, you must first call GET /api/accounts to obtain the account list:

• Match the user's specified account by email address or domain ("QQ mailbox" → IMAP qq.com)
• Only one account exists and the user says "my mailbox" → use it directly
• No matching account found → tell the user and prompt them to add one

Rule 3: Auto-Sync When the Query Is Empty

When a query returns an empty list or cannot find the specified data:

1. Call POST /{provider}/messages/fetch to sync remote data
2. Automatically retry the original query
3. Only inform the user if it is still empty

Rule 4: Prompt for a Refresh After Write Operations

After a write operation (send, reply, delete, mark, label change, etc.) succeeds, prompt: Operation completed. Do you want me to refresh the current mailbox view to see the latest state?

Core Operations

In the following, {p} denotes the provider (gmail, outlook, imap); {email} must be URL-encoded.

1. Account Management

Operation	Method	Endpoint
Get all accounts	GET	/accounts
Get accounts with settings	GET	/accounts-with-settings
Delete account	DELETE	/accounts/{p}/{email}
Get account settings	GET	/accounts/{p}/{email}/settings
Update account settings	PUT	/accounts/{p}/{email}/settings
Update display name	PUT	/accounts/{p}/{email}/displayName — body: {"displayName": "..."}

IMAP-specific:

Operation	Method	Endpoint
Get preset mailbox configs	GET	/imap/presets — returns server configs for QQ/163/Yahoo, etc.
Test IMAP connection	POST	/imap/test — body: {email, password, imap: {host, port, secure}, smtp: {host, port, secure}}
Add IMAP account	POST	/imap/accounts — same body as above plus displayName

2. Message List and Sync

Operation	Method	Endpoint	Parameters

Remote sync	POST	/{p}/messages/fetch	email, limit, folder
Manually trigger sync	POST	/sync	provider, email

folder values: Gmail/Outlook: inbox, sent, drafts, trash, spam, archive; IMAP: INBOX, Sent, Drafts, Trash, etc.

Response format (message list item):

{
  "id": "messageID", "subject": "subject",
  "from": {"name": "...", "address": "..."},
  "to": [{"name": "...", "address": "..."}],
  "date": "ISO8601", "snippet": "snippet",
  "isRead": true, "hasAttachments": false,
  "labels": ["INBOX"], "folder": "inbox"
}

3. Single Message Operations

Operation	Gmail	Outlook	IMAP
Get detail	GET /{id}?email=	GET /message?id={id}&email=	GET /{uid}?email=&folder=
Mark as read	POST /{id}/read?email=	POST /message/read?id={id}&email=	POST /{uid}/read?email=&folder=

Delete	DELETE /{id}?email=	DELETE /message?id={id}&email=	DELETE /{uid}?email=&folder=

All paths are prefixed with /api/{provider}/messages (Gmail/IMAP) or /api/outlook/ (Outlook's special routing).

Extra fields in message detail: body: {content, contentType}, cc, attachments: [{id, filename, mimeType, size}]

4. Send and Reply

Send a new email — POST /api/{p}/send:

{
  "email": "sender@example.com",
  "toRecipients": [{"name": "recipient", "address": "to@example.com"}],
  "ccRecipients": [],
  "bccRecipients": [],
  "subject": "subject",
  "body": "body (HTML supported)",
  "contentType": "html",
  "attachments": []
}

Reply to an email:

Provider	Endpoint	Body
Gmail	POST /gmail/reply	{email, messageId, body, contentType}
Outlook	POST /outlook/message/reply?id={id}&email=	{body, contentType}
IMAP	POST /imap/reply	{email, uid, folder, body, contentType}

5. Search (Gmail only)

GET /api/gmail/search?email={email}&q={keyword}

Parameter	Description
q	keyword (searches subject, body, sender)

offset / limit	pagination

6. Attachment Download

Provider	Method	Endpoint	Body
Gmail	POST	/gmail/messages/{messageId}/attachment	{email, attachmentId}

IMAP	POST	/imap/attachment	{email, uid, folder, partId}

The response result.data is base64-encoded; decode it and save to a file.

Gmail uses POST because the attachmentId may exceed URL length limits.

---

Data Sync Mechanism

The email system uses local cache + periodic polling:

• Write operations (send, mark, delete, label): update local and remote simultaneously, no delay
• Read operations (query, search): return the local cache; may be delayed (default 30-second polling)
• Remote changes (the user operates from the official web UI): wait for the next polling cycle to sync

Storage path: ~/.desirecore/mail/{provider}/{email}/ (index.json, messages/, sync.json)

---

Error Handling

Status code	Reason	Handling
400	parameter error	check the request parameters
401	authorization expired	handle per Rule 1; do not try other channels
404	resource not found	sync first and retry (Rule 3)
500	internal error	tell the user to retry later

IMAP note: domestic Chinese mailboxes (QQ, 163) require an "app password" instead of the login password. Use /imap/test to validate the configuration in advance.
