Meclaw

An agentic build system for agentic systems. Ontology-grounded, auditable, one Rust binary.

You installed meclaw. A single Rust binary that turns a directory tree into a running colony of actors: every folder is a cell, its config.json is its definition, and the edges between folders are the routes a message can take. Nothing else got installed.

You installed an operating system — without stopping anything. grow.json is not code and was not deployed. It is a mutation : nodes and edges, applied over HTTP to a colony that was already running. It grew a door, a firewall and a conversation agent out of the template library — and that is the only way anything is ever added to a colony, which is why the same door is open to the agents themselves.

You talked to an assistant nobody programmed. No SDK, no agent class, no loop you wrote. The assistant is a shape in the filesystem, grown from templates — and the full version of that shape ( examples/organism ) grows an organisation, a person, their assistant and their channels from five such files.
