This skill provides guidance for building workflow visualizations using Vercel AI Elements and React Flow. It should be used when implementing interactive node-based interfaces, workflow diagrams, or process flow visualizations in Next.js applications. Covers Canvas, Node, Edge, Connection, Controls, Panel, and Toolbar components.

Step-by-step guide for setting up Better Auth authentication with Convex and TanStack Start. This skill should be used when configuring authentication in a Convex + TanStack Start project, troubleshooting auth issues, or implementing sign up/sign in/sign out flows. Covers installation, environment variables, SSR authentication, route handlers, and the expectAuth pattern.

Comprehensive guide for building full-stack applications with Convex and TanStack Start. This skill should be used when working on projects that use Convex as the backend database with TanStack Start (React meta-framework). Covers schema design, queries, mutations, actions, authentication with Better Auth, routing, data fetching patterns, SSR, file storage, scheduling, AI agents, and frontend patterns. Use this when implementing features, debugging issues, or needing guidance on Convex + TanStack Start best practices.

This skill provides comprehensive documentation for all 23 Vercel AI Elements components organized by category (Message, Conversation, Input/Interaction, Content Display, AI Processing, Advanced Features). Use when users ask about building AI chatbots, need component documentation, want API references for Vercel AI Elements, or need integration examples with the AI SDK.

This skill should be used when working with Convex actions, HTTP endpoints, validators, schemas, environment variables, scheduling, file storage, and TypeScript patterns. It provides comprehensive guidelines for function definitions, API design, database limits, and advanced Convex features.

Customizes what information the LLM receives for each generation. Use this to control message history, implement RAG context injection, search across threads, and provide custom context.

Troubleshoots agent behavior, logs LLM interactions, and inspects database state. Use this when responses are unexpected, to understand context the LLM receives, or to diagnose data issues.

Handles file uploads, image attachments, and media processing in agent conversations. Use this when agents analyze images, process documents, or generate files.

D&D-kit combat mechanics — initiative, attack/damage resolution, XP-by-CR awards, combat modifiers, and death saves. Load when a hostile action is declared or combat starts in a campaign whose World Kit is dnd5e. For non-D&D kits, use the generic core (game_core.py) and the active ruleset instead.

The Art of Game Mastering — narration, NPC, pacing, and improvisation wisdom that makes a session feel magical. Load when narrating a scene, voicing an NPC, or pacing a beat. This is the product's soul; internalize it, then play.

Dungeon exploration — lightweight (narrative, default) vs structured (per-room JSON) modes, exit/obstacle handling, and ASCII map symbols. Load when the party enters a cave, ruin, or underground complex.

Skill-check resolution — when to roll, the DC ladder, fail-forward philosophy, and margin-based consequences. Load whenever the player attempts something uncertain ("I try to..."). Resolution runs through the generic core (d20 vs DC); this is the judgment framework for when/how.

Social / NPC interaction workflow — load NPC context, attitude check, social mechanics (Persuasion/Deception/Intimidation/Insight DCs), and persisting NPC memory + consequences. Load whenever the player talks to, persuades, or reads an NPC ("I talk to...", "I ask...").

Status conditions and exhaustion reference (blinded, charmed, frightened, grappled, paralyzed, poisoned, prone, restrained, stunned, unconscious, etc.). Load when applying or resolving a condition. Persist via gm-condition.sh (PC) / gm-npc.sh condition (party) / gm-combat.sh condition (enemies).

D&D-kit leveling — XP thresholds, the level-up ceremony, hit dice by class, and ASI/feat/subclass handling. Load when gm-player.sh xp reports LEVEL_UP in a dnd5e-kit campaign. Non-D&D kits advance via their ruleset progression model (milestone / resource-axis), not this table.

D&D-kit spellcasting mechanics — spell slots by level, casting resolution, and concentration. Load when a player casts a spell in a dnd5e-kit campaign. Spawn the spell-caster agent for spell details. Non-D&D kits use their own ruleset magic systems.
