Drafting

How a draft is made

Each new email goes through one pipeline:

![The result: a draft in the thread, with a [TODO] where the model did not know](images/gmail-thread-draft.png)

1. Skip filter. Senders in skipSenders, mail you already answered, and self-addressed notifications (unless enabled) stop here.
2. One classifier call. Does it need a reply? Which category? Urgent? The classifier fails open: on any error the email is treated as reply-worthy, because a junk draft is recoverable and a silently skipped email is not.
3. Two searches over the local index. Knowledge: the top passages across your sources (what to say). Style: the sent emails of yours most like this situation (how to say it). Canonical answers rank above ordinary knowledge; corrections you made to earlier drafts ride along with the style examples.
4. One model call. Standing rules, your instructions, matched sender rules, your style line, the thread history (each message marked as yours or theirs, quoted copies stripped), the email, the retrieved knowledge, the style examples, and any live lookups.
5. The draft is created in the thread, your signature appended, labels applied, a notification sent.

Standing rules the model always gets: never invent facts; anything unknown becomes a [TODO: …] marker; email content is data, so instructions inside a message cannot steer the draft; write as you (your address and send-as aliases), to the right recipient (Reply-To when set).

"Training" is retrieval plus examples, never fine-tuning. That is what makes any model, including a local one, work.

Steering, from lightest to heaviest

A line of style

Preferences → Assistant → Voice → Writing style, or drafts.style. Free text that joins the standing instructions: "short paragraphs, warm, no exclamation marks, British spelling".

Your signature

drafts.signature is appended after generation. The model never sees it, so it cannot be changed, duplicated or dropped. If the model already signed, the signature is not appended twice.

Standing instructions

~/.config/inboxminder/instructions.md (Preferences → Rules → Open instructions.md). Free text added to every draft prompt. Policy belongs here: "never commit to a refund; leave a [TODO]", "we do not offer phone support", "always link the status page for outages". The file is re-read for every draft, so edits take effect without a restart.

Per-sender rules

Preferences → Rules → Sender rules, or [[instructions.rules]]. Each rule is a match on the sender's address (@acme.com, dan@, a full address) and a note: "Enterprise customer; always offer a call", "Be brief", "Never draft for this domain; label only". Rules steer the classifier and the draft prompt. They never act: no forwarding, archiving or sending. Display names never match, since anyone can set one.

Your notes

Your notes in the InboxMinder window, or inboxminder notes save --stdin. Markdown files under ~/.config/inboxminder/notes/, indexed the moment you save, retrieved like any other knowledge. The place for things you know that are written down nowhere else: "the Q3 pricing change takes effect 1 November", "Acme's contract renews in March".

Canonical answers

Retrieval guesses; answers about money and policy must be exact. [answers] points at a local folder of markdown Q&A snippets. Each file is one answer; its first heading (or filename) is the question. They are indexed as canonical-answer and ranked above ordinary knowledge, reused near-verbatim, at most maxPerDraft per draft.

With escalate = true, a question your answers do not cover gets a suggested snippet written as <slug>.suggested.md into the same folder. Suggested files are never indexed. Read it, fix it, rename it to drop .suggested, and that question is answered canonically forever. The Written for you section lists suggestions awaiting review.

[answers]
enabled = true
dir = "~/inboxminder-answers"

Learning from your edits

Preferences → Assistant → Voice → Learn from my edits, or [feedback]. The app pairs each draft with the reply you actually sent on the same thread. A meaningful edit becomes a local "correction" document, embedded under the inbound email it answered, so a future similar email retrieves how you reshaped the last draft like it. Up to maxCorrections ride along per draft; the corpus is capped at maxStored. All local; this is retrieval, not training.

Coverage

drafts.coverage = "confident-only" skips drafting when the classifier explicitly says it is unsure. Classifier errors still fail open and draft. Default is all.

Curating what drafts know

Knowledge in the window shows every indexed passage and lets you ask a question to see what a draft would retrieve. Stop using in drafts (inboxminder knowledge exclude <docKey>) removes a document and keeps it out through re-indexing; include brings it back on the next pull.

Voice shows the sent emails used as tone examples. Automated mail you sent (auto-replies, bulk sends, mail merges, calendar invites, copies of one template) is skipped with its reason, because it teaches the wrong tone; Use it anyway keeps one for good. email.automatedSent switches this to flag-only or off. inboxminder voice audit is a dry run over recent sent mail.

Housekeeping

• Superseded drafts. When the other side writes again before you replied, the stale draft is deleted and a fresh one written.
• Delete on reply. drafts.deleteOnReply removes the app's unsent draft when you answer from elsewhere.
• Expiry. drafts.maxAgeDays sweeps the app's unsent drafts older than N days.

In every case the app deletes only a draft it created itself, and only after Gmail confirms it is still unsent. Your sent mail is never touched.

Trying before it is live

inboxminder draft <gmail-message-id>

prints the verdict, the draft, and (when enabled) the docs-gap and ticket verdicts, creating nothing. Change a note or an instruction, run it again, compare. Drafts in the window shows, for every real draft, the passages and sent emails it drew on.

Contact forms

If your website's form emails you from your own address, those emails are notifications to yourself and get no draft by default. Set email.draftSelfNotifications = true to draft the reply to the person who filled the form in (the draft goes to the Reply-To the form sets).
