Every criterion — derived from your own traces, not invented by us — gets a pass/fail with a confidence. Those roll into one verdict on the whole run — pass, fail, or incomplete when the evidence isn’t enough to decide: a critical failure sinks it. With fewer than 60 runs you labelled pass or fail yourself, a judge is marked unvalidated rather than trusted, so you always know which verdicts to believe.
Not to us. Traces stay on your machine; Helix reads them locally. Model calls go from your machine to the provider you signed in with, on your own credentials — we hold no provider key and add no inference bill. Nothing is sent to Mutagent unless you ask: mutagent hooks and mutagent integrations send traces to your workspace only after you set them up, /feedback shows you what it will send and waits for your confirmation, and helix update contacts the release server only to check for and fetch a build. The hosted Platform is opt-in, through the separate mutagent CLI. So are cloud runs, which run Helix in a Mutagent cloud sandbox instead of on your machine. A cloud run uses the API keys of the LLM providers in your workspace, and it does not upload your repository or local sessions.
helix. It is the full product: the five lifecycle stages and the sub-agents it starts for you. helix agent and helix --prime are subtractions from it for when you want less; see Three ways to run Helix.
Yes. Helix talks to the model provider directly. Run /login inside the session to set up a provider or subscription, or export a key (ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY, …) before launching. A launch with no provider warns “No models available. Use /login to sign in to a provider with OAuth or an API key.” — that is the missing key, not a broken install.
No. If you’re building something new, start at Spec and Build. Evaluate and Diagnose start working once you ship and your agent begins logging runs.
Run curl -fsSL https://install.mutagent.io/helix | bash -s -- uninstall. Add --purge to drop the cached runtime too.
