Apply Agency Theory (Jensen and Meckling, 1976) to diagnose principal-agent problems — moral hazard, adverse selection — and design governance mechanisms to align interests. Use this skill when the user needs to analyze conflicts of interest between owners and managers, design incentive or monitoring structures, evaluate corporate governance effectiveness, or when they ask 'how do we ensure managers act in shareholders interest', 'why is this incentive plan failing', or 'what governance mechanisms reduce agency costs'.
Answers Riverpod FAQ (ref.refresh vs invalidate, ConsumerWidget vs StatelessWidget, Ref vs WidgetRef, reset all providers, ref after unmount) and do/don't best practices (avoid init in widgets, avoid ephemeral state in providers, avoid side effects in provider init, static providers, riverpod_lint). Use when the user asks Riverpod FAQ, best practices, or do/don't guidelines.

Israeli Privacy Protection Law compliance guidance including Amendment 13 (effective August 14, 2025), database registration, consent requirements, data security, cross-border transfers, breach notification, privacy protection officer appointment, and AI governance. Use when user asks about Israeli privacy law, "haganat pratiut", "tikun 13", data protection in Israel, GDPR compliance for Israeli companies, privacy policy requirements, or database registration. Covers the Privacy Protection Law 1981, Amendment 13, and 2017 Security Regulations. Do NOT use for EU GDPR-only questions without Israeli context.
Modern SwiftUI toolbar patterns including customizable toolbars, search integration, transition effects, and platform-specific behavior. Use when implementing or customizing toolbars in SwiftUI.
Safely change and test untested codebases using Feathers' "Working Effectively with Legacy Code". Use when the user mentions "legacy code", "no tests", "untested codebase", "how do I test this", "seams", "characterization tests", "golden master", "sprout method", "afraid to change this code", "monster method", "dependency breaking", or "inherited a messy codebase". Also trigger when changing code without tests safely, getting a class under test when constructors, statics, or singletons block it, adding features to tangled modules, or planning incremental test coverage for an old codebase. Covers the legacy-code change algorithm, seams, characterization tests, sprout/wrap, and dependency-breaking techniques. For refactoring code that already has tests, see refactoring-patterns. For day-to-day code quality, see clean-code.
SwiftUI animation foundations - withAnimation, transitions, matchedGeometryEffect, PhaseAnimator, KeyframeAnimator, springs, gestures.
Profile, audit, and optimize frontend page performance with emphasis on animation work, memory-leak risks, long-session slowdowns, CSS animations, canvas/WebGL requestAnimationFrame loops, marquees, skeletons, GSAP/Three/Matter effects, timers, listeners, and observers. Use when the user asks to make animations performant, pause offscreen animations, look for memory leaks, profile pages that slow the computer over time, fix janky scrolling, reduce CPU/GPU use, or repeat the "only play in view" optimization on React/Vite/Next/frontend pages using Codex Browser.
**INTERNAL USE ONLY — invoked by `service-de-headless-channel-configure` orchestrator.** Insert an Enhanced messaging `MessagingChannel` record (plus its child `MessagingChannelUsage` as a free server-side side-effect) of any supported type — WhatsApp, LINE, Apple Business Chat, Facebook, or SMS (Text). Given a `{MESSAGE_TYPE}` and the corresponding type-specific inputs, runs the shared preflight → Connect-insert → verify flow and branches only where a type genuinely differs (request body, prerequisites, error classes). Uses the sanctioned `POST /services/data/v{V}/connect/livemessage/channels` Connect REST endpoint — no Aura session, no token extracted into shell state. **Users should always invoke `service-de-headless-channel-configure` instead — it handles insert → route → activate in one flow.** Use this skill when inserting a messaging channel of any type; it replaces the four former per-type creation skills.
Standard for exposing business logic as a uniform, agent-operable API. Postgres business actions live under a dedicated `api` schema with a fixed success envelope ({data, effects, warnings}), RFC 7807 errors, mandatory Idempotency-Key on mutations, SECURITY DEFINER auth, and preview/confirm for heavy ops. Use when creating or exposing a business action / RPC / api endpoint / MCP tool, or when reviewing one. Forward-only from 2026-06-16.
Use when a Unity 6.3 URP task involves shaders: hand-written HLSL, Shader Graph water, toon, dissolve or outline, Custom Function nodes, a renderer feature or full-screen effect on Render Graph, compute shaders, shader variants, keywords, stripping, Shader Build Settings, PSO warm-up, or shader cost; or when a material turns pink or invisible, casts no shadow, ignores extra lights under Forward+, an effect 'does nothing', the game stutters the first time something appears, or builds bloat with variants.
Use Angular CLI and development tools effectively in Angular v20+ projects. Use for project setup, code generation, building, testing, and configuration. Triggers on creating new projects, generating components/services/modules, configuring builds, running tests, or optimizing production builds.
