Nexus, by Diodorus

Nexus is the governing body for the AI agents your teams use.

It deploys agents and tools to each team, defines how they are built and what roles they play, and holds all of them to the same rules. It works with multiple model providers, caps cost per team and records every execution.

Reduces cost

Each task goes to the model that fits it, including self-hosted open source, and stays within the spending cap set for the team.

Centralizes development

Skills, tools and agent roles are built once, under the company's rules, and shared with every team.

Deploys on day one

A new team gets the agents, roles and rules already in place. There is no separate rollout.
Nexus runs on any of these model providers, with no vendor lock-in.

What goes wrong when each team adopts AI on its own.

Without a shared standard, each team builds its own setup. Four problems follow.

Fragmented adoption

Every team sources, configures and connects its own agents — no shared standard, no central view of what is running.

Unpredictable cost

Model calls multiply across teams, and no one can say how much the company is spending on AI.

Uncontrolled data

Sensitive information flows through agents no one reviewed, with no rule on what may reach a model.

Zero traceability

When something goes wrong, no record says which agent, which model and which data drove the decision.


What changes with a governing body in place.

Without governance
  • Each team picks its own agents, tools and models
  • Whoever builds an agent also decides what it may do
  • Cost is discovered on the invoice, not before it
  • No one knows exactly what each agent can reach
With Nexus
  • Every team receives its agents from one central place
  • Building an agent and bounding it are separate jobs
  • Cost is capped and visible per team, in real time
  • Every execution is logged and can be audited afterwards

How Nexus is organised: three branches.

Nexus separates who executes, who defines and who enforces. Each branch has its own scope, and none of them can override the other two.

I
Executive branch

Agents and tools in the field

The branch that gets things done. The agents and tools Nexus deploys to each team to execute its tasks and processes day to day — through chat, Slack, workflows and webhooks, on whichever model fits the job.

  • Agents
  • Tools
  • Model proxy
  • Day-to-day execution
II
Legislative branch

Skills, tools and agent roles

The branch that defines what exists. Skills and tools are developed once, each agent role is defined with a clear mandate, and everything is versioned in Git and shipped through CI.

  • Skills
  • MCPs
  • Agent roles
  • Versioned in Git
III
Judicial branch

Protocols, rules and guardrails

The branch that holds the other two to account. The protocols and guardrails that set the limits for every team's agents, checked on every run — with spend caps and a full audit trail.

  • Guardrails
  • Data rules
  • Spend caps
  • Audit trail

What Nexus does.

Nexus is one entry point for every AI agent in the company. Access, cost, security and history are managed in one place, across multiple models, connectors and skills.

01

Deploys

Executive

Every team gets the agents and tools it needs, through the channels it already uses: chat, Slack, workflows, webhooks.

02

Executes

Executive

Isolated, ephemeral workers run the day-to-day tasks and processes, across any provider, on a single bill.

03

Builds

Legislative

Skills, tools and MCPs are created once, versioned in Git and shipped through CI to every team at once.

04

Defines roles

Legislative

What each agent is, what it may touch and which models it may call — written down before it ever runs.

05

Enforces

Judicial

Guardrails, sensitive-data checks and spend caps validate every execution against the company's protocols.

06

Audits

Judicial

Every action of every agent is recorded, with a full, searchable history for whoever needs to ask.
