Hermes remembers everything. It just wasn’t ready to work.

Helmet keeps the memory and adds the harness around it.

Memory, kept.

Hermes’ long-term memory stays at the core. Helmet builds on it instead of replacing it.

Harness, added.

Planning, routing and verification arrive built in. The batteries a coding agent needs, already in the box.

Tokens, saved.

Agents exchange context through shared files, so work isn’t re-read and caches stay warm.

No jargon, no slash commands, no setup maze.

Three steps from nothing to a Hermes that works like a team.

Install with one command.

No Hermes yet? Helmet sets that up too. Hermes itself, including its default UI, becomes the supercharged version.

Describe the work.

Helmet reads the situation. No plan yet? It plans first. Then each piece goes to the right agent.

Add rate limiting to the API.

Orchestrated, not just spawned.

Most multi-agent setups launch more agents. Helmet manages them, so every token goes to work that counts.

Automatic routing.

Say what you need. Helmet decides who does it. No keywords, no triggers.

Add rate limiting to the API.No plan yet, so plan first.
Fix the failing test.Small and clear, so one worker.
Migrate to the new SDK.Large, so parallel workers.

Manage, judge, verify.

One orchestrator only manages. A read-only supervisor checks the result. Workers do the work.

Context through files.

Agents trade briefs and results in a shared folder, so nothing is repeated and caches stay warm.

Coding workflows first.

Built where Hermes ships no batteries: planning, implementing, testing and reviewing real code.

Optimized agents, not just more of them.

The orchestrator writes each prompt and keeps the plan. Workers get exactly the context they need. The supervisor checks the outcome without touching a file.

slash commands or keywords to learn before it works.

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.
