- Apply always, once-per-session, and input-sensitive approval policies

- Reject operations that cross the authenticated tenant boundary
- Regression-test approval lifecycles through the real session protocol

Getting started
Pick how you want to pull this pattern in — then wire env vars and routes the same way.
- 1
Install into an empty project directory
Copy the tokenized install command from the preview toolbar and run it in an empty directory so the Eve package and agent tree stay together.
- 2
Install dependencies and run the verification suite
With Node.js 24+, run `pnpm install`, `pnpm verify:discovery`, `pnpm typecheck`, `pnpm build`, and `pnpm eval`.
- 3
Run the Eve development server
Run `pnpm dev` after every verification gate passes.
