Load this skill before implementing a fix for a barrier that may originate in a shared component, design system, renderer, or external dependency rather than this project's own code. Decide whether the responsible fix is local, an existing installed capability, or an upstream contribution before writing a workaround. Absolutely always record any temporary local divergence with an owner and removal condition. Under no circumstances open, comment on, or submit anything in an external project without explicit human approval.

XXL-JOB best-practice patterns. A custom wrapper built on hiwepy/xxljob-spring-boot-starter, covering the @XxlJobCron annotation as a replacement for native @XxlJob (code as configuration / cron written in code / auto-registration to admin at startup), programmatic job management with XxlJobTemplate (CRUD / start-stop / trigger / automatic session renewal), executor auto-configuration (Unirest SSL / port fallback / Nacos adaptation), Micrometer metrics integration, and v2/v3 dual-version compatibility. Corrects LLM misuse: using @Scheduled instead of distributed scheduling, not knowing XxlJobTemplate's programmatic management, and not knowing the selfStarting auto-registration mode of @XxlJobCron.

Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations.

Triggers: user says "artifact", "demo", "prototype", "single-file app", "HTML tool", "interactive widget", "standalone page", building something that runs in a browser without a build step.
Manage app, IAP, and subscription territory availability with the `asc` CLI. Use this for `asc territories list`, `asc app-availability get|create`, `asc iap-availability get|create`, and `asc subscription-availability get|create`. Trigger on requests about app/IAP/subscription availability, which countries or markets are enabled, blocked territory/content status, pre-order territory status, enabling new territories, or restricting sales to specific regions.
Initialise a project's App Store Connect context using the `asc init` command. Use this skill when: (1) Saving app context to a project directory: "asc init", "pin my app ID", "set up project context" (2) Auto-detecting the app from an Xcode project: user says "run asc init in my project folder" (3) Searching by app name: "asc init --name 'My App'" (4) Explaining what .asc/project.json is used for (5) Reading saved project context to avoid running asc apps list every session (6) Saving review contact info: "asc init --contact-email ...", "set review contact", "save review contact"

Also use when extracting content for review or building content deployment pipelines -- even if they just say 'export the homepage' or 'what pages are in the shared library'.
Build forms with validation in B2C Commerce using SFRA patterns. Use this skill whenever the user needs to create a storefront form (checkout, registration, profile edit, address, contact), define form fields in XML, handle form submission in a controller, add field validation rules, or render forms in ISML templates. Also use when they mention form XML definitions, server.forms.getForm, form groups/actions/lists, or CSRF protection on form posts — even if they just say "I need a registration form" or "add validation to checkout".

Triggers automatically when the user mentions departure time, navigation routes, place lookup, coordinate conversion, or map-related development needs.
The Balanced Coupling model for software design. Use when: designing modular architectures, evaluating coupling between components, reviewing code modularity, deciding whether to split or merge modules/services, assessing integration patterns, classifying coupling as balanced or unbalanced, applying DDD strategic and tactical patterns, reasoning about cohesion vs coupling trade-offs, identifying distributed monolith risks, or explaining why a system is hard to change. Provides the three-dimensional framework (integration strength, distance, volatility) and the balance rule for making coupling decisions.
Use when porting a game project to Bevy 0.20 from another engine — Unity (Prefab, MonoBehaviour, Animator, UGUI), Unreal, Godot, Cocos, vanilla JavaScript / Phaser, Flash/SWF, Defold, Roblox, or GameMaker — and need a mapping of each engine's primitives to Bevy equivalents (`WorldAssetRoot`, `MessageWriter`, `ui_widgets::Button` + `Hovered`/`Pressed`, `AnimationGraph`, `AudioPlayer`), plus inventory/extraction scripts to pull assets out of the source project.
Guides building Vite + React SPAs with TypeScript on a fixed stack (Tailwind CSS v4, TanStack Router file-based routes, Base UI, TanStack Query, TanStack Form, Zod) on structural foundations — structure, routing, styling, UI primitives and accessibility, data, async states, errors, forms, authentication, guards — turning whatever requirements exist into that implementation. Use when creating a Vite + React SPA, or changing code in an app whose `package.json` has `vite` and `@tanstack/react-router`, to follow these conventions
