description	Draft, search, and manage emails via TextForge — human approval required before anything sends.

TextForge Email Skill

Use this skill when the user wants to draft emails, read inbox threads, search email, or manage email follow-ups via TextForge. Every email draft requires human approval before it sends.

For email composition best practices, see the email-writing skill.

ID Types

TextForge uses two types of thread identifiers:

ID Type	Format	Example	Where It Appears
Internal ID (id)	GUID	3fa85f64-5717-4562-b3fc-2c963f66afa6	list_threads, list_engaged_threads, search_threads_by_contact, matched results in search_messages
Provider ID (externalThreadId)	Hex string	19d2243fcda1917c	search_messages (unmatched results), email headers

• Use internal IDs with: get_thread, sync_thread, create_draft (threadId param)
• Use provider IDs with: get_thread_by_external_id, import_thread
• Never pass a provider ID to get_thread — it requires GUID format and will error

Workflow

1. Find context — search_messages, search_threads_by_contact, list_threads, or list_recent_messages
   • search_messages returns two groups: matched threads (already in TextForge, have an id GUID) and unmatched provider threads (only have externalThreadId)
   • list_recent_messages returns individual messages filtered by date — useful for "what came in recently?"
2. Import if needed — For unmatched results from search_messages, use import_thread with the externalThreadId to pull the thread into TextForge. This returns the internal id.
3. Read thread — get_thread with the internal id (GUID format). Do NOT pass provider thread IDs to this tool — use get_thread_by_external_id for those.
4. Draft email — create_draft with bodyFormat: "Html" (see email-writing skill for composition guidelines)
5. Attach files — get_draft_attachment_upload_url then upload via presigned URL
6. User gets notified — Slack, Discord, or webhook with draft preview
7. User reviews/approves — edit in TextForge UI, then send
8. If edits needed — use update_draft, never delete/recreate
9. Check activity — get_draft_activity to see full draft history

Never tell the user an email was "sent" — it was drafted and queued for their approval.

Quick Formatting Reference

• Use <br> for line breaks, not <p> tags
• Use <br><br> between paragraphs
• Set bodyFormat: "Html" unless the user explicitly wants Markdown
• No em dashes — they're an immediate LLM tell
• No email signatures — TextForge appends the user's configured signature

Thread Management (10 tools)

mcp__textforge__list_threads

• pageSize (number, optional): Items per page (default: 25, max: 100)

mcp__textforge__get_thread

Get full thread details including messages and threading headers for replies. Requires an internal TextForge thread ID (GUID format).

• threadId (string, required): Internal TextForge thread ID (GUID format, e.g., "3fa85f64-5717-4562-b3fc-2c963f66afa6"). Use the id field from list_threads, search_threads_by_contact, or matched search_messages results. Do NOT pass provider/Gmail thread IDs here — use get_thread_by_external_id for those.
• maxMessages (number, optional): Max messages to return (default: 5, set to 0 for all)
• stripQuotedReplies (boolean, optional): Strip quoted reply content (default: true)

mcp__textforge__get_thread_by_external_id

Look up a thread by the email provider's thread ID. Use this with provider thread IDs from search_messages results or email headers. If not found, use import_thread to import it first.

• unmatchedProviderThreads — not yet imported, have externalThreadId only — use import_thread first

• query (string, required): Search query (e.g., "from:[e-mail] after:2026-01-01", "subject:invoice", "has:attachment")

• maxResults (number, optional): Max results (default: 100, max: 500)

• pageToken (string, optional): Page token for pagination (from previous response)

mcp__textforge__search_threads_by_contact

Find all threads involving a specific email address or domain. Returns threads with full metadata including hasUnreadReply.

• email (string, required): Contact email to search for (e.g., "[e-mail]" or "@example.com" for domain)

• externalThreadId (string, required): Provider thread ID to import

mcp__textforge__list_recent_messages

List recent email messages across all threads, filtered by date and optionally by direction. Returns individual messages (not threads) with thread context (threadId, threadSubject) so you can navigate to the full thread via get_thread.

Attachment Workflow

To attach a file to a draft:

1. Create the draft via create_draft
2. Get an upload URL via get_draft_attachment_upload_url with the draft ID, filename, and content type
3. Upload the file via HTTP PUT to the returned uploadUrl:

   curl -X PUT "<uploadUrl>" \
     -H "Content-Type: application/pdf" \
     --data-binary "@/path/to/file.pdf"
   

4. The upload URL is single-use and expires in 10 minutes

To access received attachments:

1. Use list_message_attachments on a message ID
2. Use get_attachment_download_url to get a presigned download URL

Common attachment types: PDF, images (PNG/JPG), documents (DOCX), spreadsheets (XLSX).

What to Tell the User

After creating a draft:

"I've queued a draft in TextForge for your review. You'll be notified via your configured channel — approve or edit it there before it sends."

Never say "I sent an email" or "the email was sent."
