Majordomus

AI agents say the work is done; Majordomus makes them prove it.

One policy for every AI coding tool, scoped tasks with a finish contract, a mesh for many sessions and machines, and an integration queue that lands only verified work. Local; it never invokes a model.

Article

How the catalogue is organised

The catalogue has two layers. A handful of projects are featured: chosen by the owner and described in their own words. Everything else is classified automatically, so the catalogue grows with the work and never needs tending.

Each category is a rule rather than a folder. A repository lands in a category when its name, description or topics match the rule’s keywords, otherwise its primary language decides. That is how supervision of AI agents, OSINT cases, GIS catalogues and data visualisation end up side by side without anyone sorting them.

Each category page explains itself in the same way, and every project links to its open-source code.

Concepts on this page

The terms this page builds on, each defined in the glossary with a source to read further. All terms

RepositoryConcept: A project's folder under version control: its files and their whole history of commits.
Open sourceConcept: Software whose source code anyone may read, use, change and share under its licence.
AI agentConcept: A program that uses a language model to plan and act (edit code, run commands) toward a goal; Majordomus makes such agents prove their work.
OSINTConcept: Open-source intelligence: knowledge built from publicly available sources, with every claim traceable to its source.
GISConcept: Geographic information systems: data tied to places, stored, analysed and drawn as maps.
Data visualisationConcept: Turning numbers into pictures people can read at a glance: here spirals, bubbles, streams and graphs, each drawn from measured data.
