draft-follow-up

name	draft-follow-up
description	Draft a follow-up email or Slack message for a given person or thread, using the correct account. Never sends.

/draft-follow-up

Inputs

• $1: person name OR gmail thread id OR slack permalink.
• $2 (optional): intent hint — e.g. "nudge on roadmap", "thank them for the intro", "follow up on action items from last meeting".

Procedure

1. Resolve subject + channel.
   • Person name → look up + Atlas/People/<name>.md. Default channel = email if emails is populated, else Slack.
   • Thread id → fetch via matching google_* MCP; channel = email.
   • Slack permalink → extract workspace slug and thread; channel = Slack.
2. Pick the right account.
   • Email: match the person's primary email domain to the best google_* account slug. If the person is in relationship: [work], default to the work google_* MCP (see CLAUDE.md §12 for the configured work Google slug).
   • Slack: use the workspace from the permalink, or from the person's slack: frontmatter.
3. Gather context. Pull the last 1–2 interactions from + Atlas/Interactions/, the open commitments section from the person note, and the last email/Slack thread excerpt.
4. Draft the message. Apply the writing-style profile in CLAUDE.md §6 (general voice, em-dash rule, email vs Slack, audience-size split). For email: include a subject line. For Slack: no subject. All other formatting and tone choices come from §6. (To populate or refresh §6 from your real sent messages, run /learn-writing-style.)
5. Save as draft.
   • Email: call gmail_draft_email on the matching google_* MCP with mimeType: "multipart/alternative", body (plain-text mirror), and htmlBody (HTML body per CLAUDE.md §6). For in-thread replies, set threadId and inReplyTo. Report the returned draft id.
   • Slack: call slack_drafts_create on the matching mcp__slack_<workspace>__ MCP with channel_id (+ optional thread_ts for thread replies). Only one draft per channel is allowed — if one already exists, call slack_drafts_edit instead. Report the returned draft.id (format Dr0B...).
     • Channel resolution for DM drafts: the channel_id must be an IM channel id (D...), not a user id. Look up an existing IM via slack_channels_list types=im (match against the user id from slack_users_search). Opening a new DM via slack_conversations_open currently fails with missing_scope on the OpenBrain Slack OAuth grant — if no existing IM channel is found, fall back to outputting the draft text inline only and note that it wasn't stored server-side.
     • For in-thread replies the channel id is already known from the source thread, so the DM-lookup step does not apply.
6. Log vault-side trail. If $1 resolved to a person note, append a bullet under its ## Threads section so /what-am-i-missing and future lookups can see the pending draft: - <YYYY-MM-DD> · drafted follow-up (<channel>:<draft-id>) — <intent or one-line gist> Do not update last_contact — a draft is not a touchpoint.
7. Never send. If the user wants to send, they do so themselves from the Gmail/Slack client.

Output

• Account used
• Draft text (inline in chat)
• Draft id from the MCP server

Notes

• If the appropriate chat:write scope is missing for a Slack workspace, fall back to outputting the draft text inline only, with a note that it wasn't stored server-side.
• Do not draft on behalf of anyone else — only the user.
