Use CacheSphere in three steps

1. Get grounded on the real question

Pick from 300+ language and model entries with cost profiles, context limits, and efficiency signals.

2. See exactly where it holds and breaks

Get a Decision Brief with hidden costs, confidence scores, and a concrete recommendation — not just feature lists.

3. Drop it straight into your workflow

Export a Context Pack so your AI agent recommends the same stack with the same reasoning. Paste it into Cursor, Claude, or any agent that reads JSON.

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.
