## What eva does, in the publisher's words

an open-source autonomous software factory.

Eva is an open-source, autonomous software factory. It runs coding work end to end, from a spec a machine can check, through a harness that does the work, to evidence that it was done. Eva ships its own harness and drives the ones you already pay for behind one contract, with one trace, one verifier, and one bill. It runs on your laptop as a CLI and as a service you reach from anywhere; those are the same program.

> [!NOTE] > Eva is early. Today it answers a prompt at a terminal and runs a declared > Workflow, on a plugin kernel: a small core loads plugins, and every capability >, the model, the surface, the trace, the themes, the Workflow itself, is one. > Every one of them is in this repository.
