MASS
The Multi-Agent Semantic Simulator. Lexideck 2026 uses MASS to turn systems of interacting agents into interactive simulations, dynamic visualizations and executable artifacts.
MASS in Lexideck 2026
MASS is included as a reusable skill in Lexideck 2026, paired with Dexter for engineering and simulation work. Its workflow defines agents, rules and environmental bounds; runs interactions and records state; then presents the resulting dynamics in an inspectable artifact. Read the current MASS skill for the protocol and artifact standards.
MASS supports particle systems, ecological and economic models, network propagation and other interacting systems. MASH explores the related idea of experiencing a world from within.
The modeling approach
MASS models complex systems as networks of informatic exchanges: entities have states, interactions change those states, and repeated exchanges produce patterns that can be observed. This approach connects to the Informatic Exchange Geometries research framework.
The current skill calls for explicit parameters, a simulation trace and a summary of observed behavior. The Sieve governs the work, including consent when modeling real individuals and accuracy when visualizing real-world data.
Manifold Pulse
A 3D exchange-flow screensaver with six directional agent fields, particle interactions and a slow camera orbit. Choose a preset to explore ring, paired and interwoven flows. Stable prescribed fields are the default. Zoom freely as the camera slowly orbits, or turn off the orbit for a still view; advanced controls expose the underlying model.
Field strength and orientation guide the particles through classical dynamics inspired by UIT-IEG exchange geometry.
Cellular worlds
Explore classic Conway Life, six-agent Lexideck Life, independent site percolation and Exchange Life. Seed a world, step through its evolution, and inspect connectivity. Lexideck Life gives six rule families a shared neighborhood; Exchange Life adds a local information budget inspired by UIT-IEG.
The exchange rules are specified modeling choices; the energy ledger uses dimensionless units, not measured joules.
