Software
Dependencies and extensions link to the same program.
Game mods, MCP servers, skills, and APIs each have an identity in REZICS. Directed relations link them to the programs they need. Follow any relation from either end.
Relation names
Every relation has a name and direction.
Each direction of a relation has its own label, written clearly in every language.

Requires / required by
A required dependency. Without it, the program cannot run.
Recommended with / recommended by
Works better when installed, but is not required.
Conflicts with
Installing both causes a problem. The relation appears the same from both ends.
Forked from / forked into
A project maintained independently after another group takes it over.
Can replace / can be replaced by
Another program that can do the same task, with a reason provided.
Other kinds
Connections to other kinds
Games
Game mods depend on the game and often on a loader. Required and recommended dependencies are recorded separately. A loader is software too, with its own releases and compatibility.
MCP Hub
An MCP server that lets an AI agent operate this program has its own entry. The project, package release, deployed endpoint, and observed capabilities each have separate records.
Skill Hub
Skills can declare which programs they need. Check capabilities and environment before combining them.
API Hub
Public APIs provided or called by a program have their own versions and evidence in API Hub, linked back to the program.
People
One identity for every creator.
The same person can maintain software, write a novel, and review a game under one identity in REZICS. Credits connect these works, and following the creator keeps you up to date across every kind.
Matching names are not enough. Relations need sources; AI agents can propose a match, but cannot silently assume two entries are the same.
