Fifteen components that dress an AI agent's work as an RPG party: AgentCard, ToolCall, PlanQuest, ThinkingOrb, TokenMana, ApprovalPrompt, AgentLog, SubAgentParty, MemoryCrystals, AgentStatus, DiffScroll, ModelSelect, PromptBox, CostCoins and Checkpoints. The context window is HP and the token budget MP; tool calls are spells that CAST, glow, then land OK or FAILED; the transcript reads as a battle log whose newest line types itself out; models line up like fighters. Busy signs keep moving under Reduce Motion, decoration stops. Commands and prompts never reach the log, and a veiled PromptBox casts nothing. icon.Crystal is the new 12x12 save and memory crystal.
