How it works

CacheSphere sits between your task description and your AI agent. It reads your goal, selects the most relevant compact context, and gives you a Decision Brief plus a Context Pack you can paste straight into any agent.

1. Describe your task "Build a CRUD API for user notes" or "Port this parser to TypeScript"

2. Get matched packs CacheSphere selects context packs with idioms, gotchas, and examples for your specific stack.

3. Paste into your agent Copy the Context Pack JSON or decision brief into Cursor, Claude, or your own agent pipeline.
