Agent orchestration · YAML → LangGraph

xteam-agents Active Development

Assembling multi-agent automation from YAML specifications without rewriting code: the specification produces the graph and the agent topology.

The problem

Multi-agent automation for a specific process is expensive to build and change if every edit means rewriting code.

Why existing solutions fail

Hard-coded pipelines do not carry over to a new process without rework; the topology cannot be changed declaratively.

How it works

YAML specification → LangGraph graph → Mermaid topology; an agent registry queried by role and capability. We show the topology and the names; the routing heuristics are not disclosed.

Demo

Graph topology: __start__ → analyze → plan → execute → validate, conditional transitions to commit / plan / reflect, then commit → reflect → __end__; at the side, a “node → agent” map.
The cognitive_os pipeline is assembled from a YAML specification into a LangGraph graph — the diagram is the real draw_mermaid() output of the built graph, not a drawing.

Use cases

Automation tailored to a process

A multi-agent build for the client’s specific process, without rewriting code for every task.

Declarative topology

The agent topology changes by editing YAML, not code — the process carries over to a new environment declaratively.

Evidence

YAML → LangGraph graph → Mermaid topology + a registry of 29 agents

A working graph is built from the specification and the topology is rendered; a registry of 29 agents queried by role and capability. We show the topology and the names.

Reproduce: graph_builder.build(spec) → Mermaid

Green test run: 197 passed

A snapshot of a run at a pinned revision: 197 passed with the known non-green tests excluded — an honest boundary of maturity, not “everything is green”.

Reproduce: pytest

Integration

Agent topologies are described in YAML and assembled into a working graph for the client’s process.
