Give Your AI Agent a Living Cosmic Interface — A Voice-Reactive 3D Orb and a Constellation of Floating Sub-Agents in One Session

Paste this into Claude Code, Cursor, or Aider and it'll walk your agent's web frontend through building the same interface used by a production voice assistant: a full-screen scene with a procedural deep-space nebula, a wireframe orb that breathes and deforms in real time with the user's voice and shifts color by conversational state, and a constellation of sub-agent avatars that orbit the orb, light up when dispatched, trail beams and pulse rings, and dock near their panels while they work. Interview first, then build tier by tier. Each tier renders something on screen and is verified before the next begins.

Give Your Sub-Agent Team Prompt Caching — From Re-Paying for Every System Prompt to a High Cache-Hit Rate in One Session →

Paste this into Claude Code, Cursor, or Aider and it'll audit every place your agent team calls the Anthropic API, find where you're re-sending large system prompts and tool schemas at full price on every sub-agent call, and add cache_control in the right places — the shared tool loop, the main conversation history, and the per-agent one-shots — while catching the silent invalidators (a timestamp in the system prompt, an unstable tool order) that quietly keep your hit rate near zero. Audit first, then fix tier by tier. Each fix ships independently with before/after verification from the usage numbers you already get back.
