Cas d'usage

Usages concrets : symfony-ux-skills

How to build a Symfony Live Component with Claude

👤 Symfony developers adding real-time UI without writing JS ⏱ ~20 min intermediate

Quand l'utiliser : You need a reactive form, filter, or list that updates on the server without a full page reload.

Prérequis

Symfony 6.4+ project with symfony/ux-live-component installed — composer require symfony/ux-live-component
Skill cloned into ~/.claude/skills/ — git clone https://github.com/smnandre/symfony-ux-skills ~/.claude/skills/symfony-ux-skills

Déroulement

Describe the component you need

Build a Live Component for a product search filter with checkboxes for categories and a text query — updates results live as the user types.✓ Copié

→ Claude references LiveProp, LiveAction, debounce modifiers from the skill
Let Claude scaffold the PHP + Twig

Generate the PHP component class and the Twig template. Use attributes, not annotations.✓ Copié

→ File output follows Symfony UX naming (src/Twig/Components/...)
Ask Claude to wire the parent page

Show me how to embed this component in an existing Twig page and pass initial state.✓ Copié

→ Uses {{ component() }} helper correctly

Résultat : A working Live Component with proper LiveProp typing and no custom JS.

Pièges

Claude mixes Live Component and Twig Component concepts — Re-ask naming the package explicitly: 'use symfony/ux-live-component, not twig-component'

Combiner avec : filesystem · git

Refactor legacy JS into a Stimulus controller

👤 Developers modernizing a Symfony app's front-end ⏱ ~15 min beginner

Quand l'utiliser : Your app has jQuery or vanilla JS sprinkled in Twig — you want to move to Stimulus cleanly.

Prérequis

Symfony UX + Stimulus configured (importmap or Webpack Encore) — symfony console importmap:require @hotwired/stimulus if missing

Déroulement

Paste the legacy snippet and ask for a Stimulus conversion

Convert this jQuery snippet to an idiomatic Stimulus controller with targets and values.✓ Copié

→ Controller with static targets, static values, clear actions
Update the Twig template

Show me the data-controller, data-*-target, and data-action attributes for the Twig side.✓ Copié

→ Correct data attributes, no inline handlers

Résultat : A clean Stimulus controller plus Twig wiring, ready to commit.

Pièges

Controller name mismatch between file and data-controller attribute — Remind Claude of the naming rule: hello_controller.js → data-controller=hello

Combiner avec : filesystem

Add Turbo-powered pagination without a page reload

👤 Symfony devs who want SPA-like UX with minimal JS ⏱ ~15 min intermediate

Quand l'utiliser : You have a paginated list and want Next/Prev to swap content in-place.

Déroulement

Ask Claude to wrap the list in a Turbo Frame

Wrap my paginated product list in a turbo-frame and make pagination links target that frame.✓ Copié

→ Uses <turbo-frame id=...> and frame-targeted links
Handle the partial response

Update the controller to render only the frame when the request has the Turbo-Frame header.✓ Copié

→ Controller checks request header and picks the right template

Résultat : Pagination swaps in-place with no full-page reload.

Pièges

Full page keeps reloading — Frame id on the link target must match frame id on the page — repeat it to Claude

Combiner avec : filesystem

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

symfony-ux-skill + filesystem

Claude reads your existing Twig/PHP and writes components matching codebase style

Read src/Entity/Product.php and src/Twig/Components/, then add a new LiveComponent for a product filter following the same patterns.✓ Copié

symfony-ux-skill + github

Open a PR with the new component once files are on disk

Commit the new LiveComponent files to a branch and open a PR titled 'Live product filter'.✓ Copié

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
live-component-authoring	component intent, props, actions	You need a reactive UI piece in Symfony	0 — prompt-only
twig-component-authoring	UI primitive description	Reusable presentational block with no live server interactions	0
stimulus-controller-authoring	behavior + targets/values	Client-side interactivity that doesn't need the server	0
turbo-integration	frame/stream intent	Partial-page updates and form responses	0

Coût et limites

Coût d'exécution

Quota d'API: none — skill is local markdown
Tokens par appel: adds ~2–8k tokens of context when the skill activates
Monétaire: free, MIT-licensed
Astuce: Keep the skill dir small — clone only the subskills you use if context-constrained

Sécurité

Permissions, secrets, portée

Stockage des identifiants : none — no credentials needed

Sortie de données : none — pure instruction bundle, no network calls

Dépannage

Erreurs courantes et correctifs

Skill doesn't activate

Confirm the directory is ~/.claude/skills/symfony-ux-skills/ and contains SKILL.md at the root. Restart Claude Code.

Vérifier : ls ~/.claude/skills/symfony-ux-skills/SKILL.md

Claude uses generic PHP instead of Symfony UX

Prompt explicitly: 'use the symfony-ux-skills you have loaded'

Generated code references UX packages you don't have installed

composer require the package, or tell Claude which packages are installed

Vérifier : composer show | grep symfony/ux
