livewire-architect

Architectural lens above the existing tactical livewire skill. Decides component shape, lifecycle ownership, and the full-page-vs-partial split before the first mount() is written. The livewire skill handles Flux-component patterns and hydration debugging once the shape is locked.

When to use

• A Livewire feature is about to be built and the boundary between components is unclear (one big component vs nested children?).
• An existing component is "doing too much" — multiple unrelated concerns, large $listeners, props bag growing turn over turn.
• A page mixes Livewire + Blade partials and the data flow is ambiguous (who owns $user, who emits, who listens?).
• German triggers: "wie schneide ich das?", "Vollseite oder Teilkomponente?", "wer feuert das Event?".

Do NOT use when:

• The shape is already locked and the question is mechanical (Flux variant, wire:model modifier, @entangle) — route to livewire.
• The page has no Livewire — pure Blade or Inertia/React — route to blade-ui or react-shadcn-ui.
• The bug is a runtime hydration error — debug with livewire, not redesign with this skill.

Procedure

1. Analyze the existing screen — before designing anything

Inspect the route and read the existing Blade / Livewire files to understand what's already there. List every dynamic surface on the page (form, table row, modal, nav badge). Mark each: shared state (other surfaces re-render on change), local state (only this surface cares), server state (must hit DB / queue). This analysis feeds every later step — do NOT skip ahead before the inventory is on paper.

2. Choose the component shape

Pick one before writing code:

Shape	When	Cost
Full-page component	Route owns the whole screen, single backing model, ≤ 3 related actions	Cheapest; one mount, one render
Parent + nested children	Two or more independent state islands on one route	Two mounts; coordinate via events, not props churn
Partial component on Blade	Mostly static page, one reactive island	Cheap; component sees the world via props only
Stack of full-page components	Wizard / multi-step flow with own URL per step	Expensive; pick only when URL semantics matter

Rule: if a child needs ≥ 4 props from the parent and emits ≥ 3 events back, the boundary is wrong — collapse or re-cut.

3. Lock the state-vs-props boundary

For each piece of data the component reads, mark public property (reactive, persisted in payload, expensive to dehydrate) or computed / method-local (cheap, recomputed on render). Public properties are the budget — keep ≤ 8 per component; more means the component is doing two jobs.

4. Map the event flow

Draw the events: dispatch('foo') → who listens? Cross-component events use dispatch(); parent ↔ child stays on $parent.method() when the child is owned. Avoid global events for parent-owned children — they break the ownership story.

5. Lifecycle ownership

For each side-effect (DB write, queue dispatch, redirect, flash), name the lifecycle hook: mount (one-time setup), boot (every request, idempotent), action method (user-initiated), updated* (reactive on property change). One hook per side-effect; if two hooks fire the same write, the design is wrong.

6. Validate the design — before any code is written

Walk the design back through these checks; every "no" means re-cut, not push forward:

• Each component owns ≤ 8 public properties.
• No child needs ≥ 4 props and emits ≥ 3 events back.
• Every event has exactly one named listener.
• Each side-effect maps to exactly one lifecycle hook.
• The component shape table is filled in (no <TBD> cells).

If any check fails, return to the relevant step and re-cut. The design must be approved by the user before handing off to /livewire for implementation.

Output format

Return:

1. Component shape decision — full-page / parent+children / partial / stack — with the one-sentence trade-off rationale.
2. Component inventory — for each: public props (≤ 8), state islands owned, events listened/dispatched, side-effects on mount and action.
3. Boundary-risk list and tactical follow-up — prop bags > 8, event chains > 3 hops, shared mutable state, and the next handoff.

Concrete shape:

Screen:           <route or feature>
Component shape:  <full-page | parent+children | partial | stack>
Why:              <one sentence — the trade-off chosen>

Components:
  - <Name> (full-page | partial)
      Public props: [a, b, c]   (≤ 8)
      Owns:         <state islands>
      Listens to:   [event1, event2]
      Dispatches:   [event3]
      Side-effects: mount=<...>, action=<...>

Boundary risks:
  - <prop bag > 8 / event chain > 3 hops / shared mutable state>

Tactical follow-up:
  Hand off to /livewire for Flux variant + hydration check.

Gotcha

• Livewire 3 reactive props are not free — every public property ships in the payload. Big arrays / DTOs as public state are a performance bug waiting to fire under load.
• Parent-owned children and global events do not mix; pick one ownership story per component tree.
• "Just one more public property" is the smell that turns a partial into a god-component over three tickets.
• Full-page component + Flux modal stack: the modal owns its own mount cycle; do not push modal state into the page component.

Do NOT

• Do NOT write mount() / Blade partials before the shape table is filled in — picking the shape after coding is the most common source of refactor debt.
• Do NOT cite this skill alongside livewire in the same step — they sit at different tiers; pick one per phase.
• Do NOT design Inertia / React components with this skill — the state-vs-props axis differs; route to the matching stack skill.
• Do NOT push the architecture into the tracker as code AC — output is a design note for refinement, not implementation steps.
