Grounded stack guidance: pull idiomatic Blade/UI Do/Don't + docs URLs via ground.py search --manifest <skills-root>/design-intelligence/data/manifest.json --stack laravel "<topic>" (UI-scoped corpus). See design-intelligence.

Positioning — dispatched, not standalone

livewire is the apply-step executor for the Livewire stack. It is invoked by directives/ui/apply.py once the design brief is locked, and revisited by review.py / polish.py during the design-review loop. It does not own the flow, does not drive the audit, and does not lock the design.

When to use

Cite this skill when:

• state.stack.frontend == "livewire" and directives/ui/apply.py dispatches to this skill
• Editing or creating Livewire components — reactive state, forms, tables, real-time updates

Do NOT use when:

• Static Blade views with no interactivity (use blade-ui skill)
• Flux UI primitives (use flux skill — livewire composes Flux internally)
• Driving the full UI flow yourself — that is the directives/ui/ orchestrator

Procedure: Create a Livewire component

Step 0: Inspect

1. Detect Livewire version — composer.json for livewire/livewire.
   • v3: #[Layout], #[Title], property attributes.
   • v2: $layout, $listeners, method-based hooks.
2. Check existing components — app/Livewire/ or app/Http/Livewire/.
3. Check views — resources/views/livewire/.

Step 1: Create component class

1. declare(strict_types=1), final class.
2. Typed public properties for state — keep minimal.
3. #[Locked] for tamper-proof properties.
4. #[Url] for URL-synced properties.

Step 2: Implement actions

1. Public methods callable from frontend.
2. Validate before processing: $this->validate().
3. $this->dispatch() for cross-component communication (v3).

Step 3: Create view

1. One root element (<div>).
2. wire:key on dynamic lists.
3. wire:loading for user feedback.
4. wire:model.live for real-time updates (v3 default is deferred).

Step 4: Test

• Livewire::test(ComponentClass::class)
• ->set(), ->call(), ->assertSee(), ->assertHasNoErrors()

Conventions

→ See guideline php/livewire.md for state management, forms, performance, Alpine.js, templates.

Output format

1. Livewire component class with typed properties and actions
2. Blade view with wire: bindings and Flux components

Review pass — a11y findings + preview envelope

When this skill is dispatched by directives/ui/review.py (test slot) or directives/ui/polish.py (verify slot) — i.e. a review/polish run, not the initial apply — it also emits:

• state.ui_review.a11y — {violations: [{rule, selector, severity}, ...], severity_floor?, accepted_violations?}. Use the same (rule, selector) shape as state.ui_audit.a11y_baseline so the engine's de-dup matches pre-existing entries on replay. Omit the envelope on apply passes; the engine's _apply_a11y_gate only fires when a baseline is present.
• state.ui_review.preview — {render_ok: bool, screenshot_path?, dom_dump_path?, error?, skipped?}. render_ok: false with error populated triggers the preview_render_failed halt; render_ok: true with screenshot_path threads the screenshot into the delivery report's artifacts list. Browser tooling (Playwright/Cypress/…) is a consumer-project dependency — this package does not ship one.

Polish dispatch: when the dispatcher skips review because a previous review pass already returned SUCCESS, this skill MUST itself synthesise the updated state.ui_review.findings (including any remaining a11y_violation entries) so the engine's gate sees the current state on the next polish round.

Gotcha

• Public properties serialize between requests — don't put large objects in state.
• wire:model is deferred by default in v3 — use wire:model.live for real-time.
• $this->redirect() + $this->dispatch() in same method — only redirect executes.

Do NOT

• Do NOT put heavy computation in render() — it runs on every update.
• Do NOT nest Livewire components deeply — keep the tree shallow.
• Do NOT expose sensitive data as public properties.

Anti-slop

When a Livewire component renders UI, pull docs/guidelines/design-antipatterns.md for the Visual / Layout / Motion checks (loading states that animate layout properties — M2 — are a common Livewire wire:loading pitfall). Stack styling bans: tailwind-engineer.
