The orchestrator writes each worker a short brief. Workers build in parallel. The supervisor reads the result and never edits a file.

No setup maze.

FAQ

Everything you need to know.

Do I need Hermes already?

No. One command installs Helmet and, if you don’t have it yet, Hermes too.

Which models does it work with?

Whichever you plug in. Helmet routes between them automatically, so you don’t pick tiers or write routing rules.

Do I need to learn commands?

No. Describe the work in plain language. Helmet reads the situation and decides what happens next.

How does it save tokens?

Agents exchange context through a shared folder instead of re-reading everything, and prompts stay stable so provider caches keep hitting.

Is it free?

Yes. Helmet is an independent open-source project. [LICENSE AND REPO LINK]

Helmet on. Ship.

One command to a Hermes that plans, routes and verifies.
