Harness engineering for AI coding agents — five subsystems, memory persistence, session continuity, verification workflows, scope control, lifecycle management.
Design backend services, APIs, and server-side boundaries. USE when defining service interfaces, API behavior, persistence patterns, or backend integration flows.
Use when implementing save/load systems, player progress persistence, or data serialization in Unreal Engine. Triggers on: save game, USaveGame, FArchive, serialization, SaveGameToSlot, config, persist data, save file, load game. See references/save-system-architecture.md for full slot management and multi-user patterns.
Retrieves historical PubNub messages via Message Persistence (Storage & Playback). Covers timetoken-based pagination, per-channel ordering guarantees, offline catch-up flows, retention configuration, and the "catch-up tool not a data lake" principle. Use when fetching past messages, paginating with timetokens, building offline-resume UI, retrieving messages with actions, or configuring retention.
Session context persistence for AI coding. Start/end sessions, create specs and docs, review work. Use for session management, "start session", "end session", implementation specs, documentation, code review, or questions about previous work, decisions, blockers, "last time", "what we decided".
State persistence patterns for autonomous-dev including JSON persistence, atomic writes, file locking, crash recovery, and state versioning. Use when implementing stateful libraries or features requiring persistent state.
Durable UI patterns for modern web development — persisting client-side state across page loads, browser sessions, and shareable URLs. Use this skill when implementing localStorage persistence, URL query parameter state, form draft auto-save, multi-step wizard persistence, click-outside dismissal, modal/dialog backdrop patterns, or any client-side state and interaction pattern that should be resilient and well-behaved. Works with React, Vue, and Svelte.
File-based knowledge persistence patterns: when to store discoveries, when to recall past solutions, and how to organize project memory. Activate when starting tasks, encountering errors, making decisions, or when context may be lost between sessions.
Configure Akka.NET with .NET Aspire for local development and production deployments. Covers actor system setup, clustering, persistence, Akka.Management integration, and Aspire orchestration patterns.
Vector embeddings with HNSW indexing, sql.js persistence, and hyperbolic support. 75x faster with agentic-flow integration. Use when: semantic search, pattern matching, similarity queries, knowledge retrieval. Skip when: exact text matching, simple lookups, no semantic understanding needed.
Common utilities and features for Syncfusion Angular components. Use this skill when the user needs to implement animations, drag-and-drop, state persistence, RTL support, localization, globalization, security, templates, and advanced features for Syncfusion Angular components.
Build responsive, interactive dashboard layouts with Syncfusion React Dashboard Layout component. Implement draggable and resizable panels, responsive grid systems, dynamic panel management, and state persistence. This skill covers multi-column layouts, floating panel arrangement, extensive customization, drag-drop panel rearrangement, and state management for React applications.
