Coach modules¶
A coach module is a reusable building block for coach conversations — a greeting, a closing prompt, or a conditional segment — authored once and spliced into many conversations. This keeps repeated content in one place.
Follow The authoring model for parent/translations, status, slugs, and validation.

Parent fields¶
| Field | What it means |
|---|---|
| Slug | Stable id, e.g. welcome-back-morning, optional-add-checkin. A conversation references a module by this slug (as its opening or closing module). |
| Type | pool or conditional (see below). |
| Selection | For a pool module, how a variant is chosen (e.g. rotate). |
| When predicate | For a conditional module, the condition that decides whether/which content shows. |
Translation fields¶
A module carries its content per language, in one of two shapes depending on type:
pool→ variants: a list of alternative item-lists. The Coach picks one variant (per the selection rule) — e.g. a set of interchangeable morning greetings so the opener doesn't feel repetitive.conditional(and simple modules) → items: a single list of items, shown when the predicate matches.
In both cases the items are the same chat-item types used in conversations (messages, reply chips, cards, etc. — see Coach Conversations → item types). The save-time check validates module items and every variant's items with the same rules as conversations.
How modules reach the user¶
A conversation names an opening module and/or closing module by slug. At
play time the Coach splices the module's items in around the conversation's own
items. A pool module contributes one chosen variant; a conditional module
contributes its items only when its predicate matches.
What blocks a save¶
- Any malformed item inside the module's items or a variant's items (same rules as conversations).
- Renaming the slug while a translation is published (a conversation may reference it).
Where it shows up¶
Indirectly — module content appears inside whichever conversations reference it, at the start (opening) or end (closing) of the chat.
