Use when building UI with @toolcase/web-components — framework-free HTML5 Web Components (`tc-*` custom elements) with from-scratch toolcase styling and a Bootstrap-compatible class API. Covers layout (BasicLayout, DashboardLayout, DashboardContent, DashboardSidebar, Login, Container, Row, Col, Spacer, Stack), content (Accordion, AccordionItem, ActionHeader, ActionItems, ActionRowList, Alert, AnnouncementBar, ApiReferenceTable, AssetRow, AssetRowList, Avatar, Badge, BadgeRow, Banner, Brand, Build, BriefCard, BundleBar, CdnMap, CalloutQuote, Changelog, ChartContainer, Sparkline, TrendIndicator, Leaderboard, LeaderboardTrend, CodeLabelCell, CodeSnippet, CodeWithOutput, CommunityLinks, ConfigPreview, ContributorWall, CookbookGrid, CoolButton, ActivityCard, BasicCard, Button, ButtonGroup, Card, Carousel, CloseButton, Collapse, Divider, Dropdown, DownloadStats, EcosystemMap, EmptyState, GameShowcaseCard, GithubStarsCard, GoodFirstIssues, Group, Hero, HeroStatsBar, Heading, Image, InfiniteScroll, Kbd, ListCard, Lis
Use when reaching for @toolcase/base — zero-dep TypeScript helpers + data structures (Cache, PriorityQueue, RingBuffer, Stack, Deque, VectorClock, State, AdjacencyMatrix, ObjectPool, WeightedRandom, BiMap, BloomFilter, MultiMap), events (EventEmitter, Broadcast), pathfinding (Dijkstra, AStar — class-based, step()-controlled, event-emitting), rectangle/atlas packing (Packing.Packer + MaxRects/Guillotine/Shelf/Skyline/BinaryTree algorithms, multi-page, POT, trim/extrude), spatial partitioning (Spatial.SpatialHash grid + Spatial.Quadtree — insert/remove/update/range-query/nearest-neighbour), async utilities (Deferred, Semaphore, Mutex, pLimit, withTimeout, sleep, debounce, throttle, AsyncQueue — backpressure-aware producer/consumer channel), easing functions (30 easeIn*/easeOut*/easeInOut* functions for Sine/Quad/Cubic/Quart/Quint/Expo/Circ/Back/Elastic/Bounce families plus a CSS-compatible cubicBezier sampler — all exported individually and as Easing namespace), scalar math helpers (clamp, lerp, inverseLerp, ma
Use when wiring @toolcase/logging — tiny isomorphic logger with named loggers (scopes), level filtering (silent/error/warning/info/debug/verbose), and pluggable LogReporter sinks (console default, custom transports for remote/file/etc).
Use when reaching for @toolcase/node — backend helpers for Node.js. Single entrypoint exposing Fastify endpoints (RouteHandler, RESTRouteHandler, Router, HttpServer), engine-agnostic repositories (BaseRepository, EntityService — you implement the verbs for your engine), Redis KV service (KVService — Locker, RateLimiter, Leaderboard, ValueStore, Versioned, SubscriberPool, KeyBuilder, LuaScriptCache), NodeStore + BlockStore (two-file persistent key-value store: B+ tree index + append-mostly heap), OAuth2/OIDC helpers, ImageProcessor + AtlasBuilder (sharp), typed env() loader, plus isomorphic sanitize / pagination / filter / sort / domain-error helpers and FieldSchema → JSON Schema derivation.
Use when scaffolding or extending a Phaser 4 game built on top of `@toolcase/phaser-plus`, with `@toolcase/web-components` as the canonical UI toolkit (HUDs, menus, inventories, dialogs, screens). Defines workspace layout (scenes/ + features/ + ui/ + prefabs/), layering rules (Scene → Feature/HTMLFeature → Prefab GameObject), boot sequence with `installEffects` + `register()` + `style.css`, lifecycle contracts (`onInit/onLoad/onCreate/onUpdate/onDestroy` for scenes, `onCreate/onUpdate/onDestroy` for features, `onCreate/onAdd/onUpdate/onRemove/onDestroy` for game objects), the FeatureRegistry pub-sub bus, GameObjectPool registration/obtain (and ObjectLayer.add for positioned pool-backed spawning), the `dom: { createContainer: true }` HTMLFeature requirement, and the rule that HTMLFeatures compose `tc-*` Web Components instead of hand-rolled markup. Apply when adding a scene, feature, UI overlay, prefab, or scaffolding a new Phaser game workspace.
Use when building Phaser 4 games with @toolcase/phaser-plus — scene lifecycle, feature registry, object pooling, flow events/timers/jobs, layer + camera management, perspective2d (isometric/grid), GLSL shader effects, particle VFX (ParticleFeature), A* pathfinding (NavMesh), and the Tweakpane in-game debugger.
Use when reaching for @toolcase/serializer — runtime-defined protobuf message schemas, encode/decode to compact binary Uint8Array buffers via protobufjs/light. Good for game netcode, websocket payloads, IPC, and any compact wire format that doesn't need a .proto build step.
Use when reading or modifying the TaskForge application source (taskforge/) or when understanding how a TaskForge-managed project workspace is structured. Covers the full architecture: Next.js 15 + node:sqlite backend, 16 SQLite repositories and their schema, ~60 API routes by area, three-tier role model, multi-account LRU orchestration (account-repo / account-lru / account-secrets, per-task **Account:**, DEFAULT_ACCOUNT, cooldown/failover), cron scheduler (5-field subset), reviewer pass (review.ts, needs-review status), four bundled skills (task-creator / knowledge-writer / note-writer / commit-message), notes vs knowledge distinction, telemetry + usage gate, warm sessions, Git surface, audit / health / backups / search, webhook notifications, per-project settings, and GitHub allow-list / org membership gating.
