Integrate Game Center features using GameKit. Use when authenticating GKLocalPlayer, checking player restrictions, submitting leaderboard scores, reporting achievements, implementing real-time or turn-based matchmaking, handling GKMatch data, showing the Game Center dashboard or access point, adding challenges and friend invitations, saving game data, or verifying player identity on a server.
Keep a long-lived project's documentation from rotting by assigning existing project docs clear constitution, map, status, and history roles, then wiring the active agent harness to those canonical sources. Use in the maintain phase when docs drift from code, agents lose context between sessions, or intentional removals keep being recreated. Prefer adopting the repository's current docs structure over creating new root files. 中文触发：文档治理、活文档、项目状态追踪、防文档漂移、项目地图、健康仪表盘、删除区、长期项目治理

Generates a minimal, ready-to-develop SFDX starter project from a template instead of scaffolding files by hand. Use this skill when starting a brand-new Salesforce UI bundle app (React or Angular) and the initial project must be scaffolded. Trigger phrases include create, start, or scaffold a new UI bundle app, generate a starter project, or use a prebuilt/starter template. DO NOT TRIGGER when: editing, styling, or adding pages or components to an EXISTING app (use experience-ui-bundle-frontend-generate); configuring ui-bundle.json or metadata files (use experience-ui-bundle-metadata-generate); deploying to an org (use experience-ui-bundle-deploy); when the user explicitly says they want to hand-scaffold from scratch; or when creating a brand-new standalone Salesforce project that also needs full setup—relocating the session, connecting an org, setting the default, and enabling source tracking (use dx-project-create in the salesforce-development plugin).

Canonical patterns for writing custom MSBuild targets. USE FOR: diagnosing and fixing custom target authoring anti-patterns; broken SDK target chains across files (e.g., Directory.Build.targets silently redefining SDK targets); targets that replace CompileDependsOn instead of extending it with $(CompileDependsOn); query targets returning stale results from Outputs vs Returns misuse; missing Inputs/Outputs causing unnecessary rebuilds; missing FileWrites registration. Covers DependsOnTargets vs BeforeTargets vs AfterTargets, the Build→CoreBuild three-level pattern, and the $(XxxDependsOn) chain-extension pattern. DO NOT USE FOR: incremental build tuning (use incremental-build), parallelization (use build-parallelism), general anti-patterns (use msbuild-antipatterns), non-MSBuild build systems.
Runs anonymous Apex against the connected org (.apex file or pasted snippet), capturing the debug log and surfacing errors. Triggers on “run this anonymous apex,” “execute this script against my org,” “what does this code return,” or “execute scripts/foo.apex.” Wraps scripts in savepoint+rollback; warns before running in production. Do not trigger for authoring .cls/.trigger files (platform-apex-generate), Apex unit tests (platform-apex-test-run), or debug-log analysis (platform-apex-logs-debug).
Make interactive Blazor components work correctly with prerendering. USE FOR fixing duplicate data loads, UI flicker during prerender-to-interactive handoff, null references during prerender, persisting state across prerender, disabling prerendering, excluding pages from interactive routing, or detecting whether a component is currently prerendering. DO NOT USE for choosing which render mode to use (see create-blazor-project) or general component authoring (see author-component).

Write, route, cache, and debug Netlify Edge Functions, the Deno-based TypeScript or JavaScript handlers in netlify/edge-functions that run at the network edge in front of static files and serverless functions. Activate this skill whenever someone wants to add auth middleware or a login gate, redirect or rewrite visitors by country or cookie, localize or personalize a page with geolocation, run A/B testing, transform or inject HTML into a response, stream server-side rendering at the edge, or cache an edge response. Also use it when an edge function silently does nothing, runs in the wrong order, ignores its Cache-Control headers, or cannot read an environment variable.
