Monomer Tutorial

​

Selection Flow

1. Identify the operation in plain language.
2. Search the Monomer Catalog.
3. Prefer core monomers when they express the operation.
4. Use extended monomers only when the behavior crosses into external or specialized domains.
5. Record any external dependency before composing the PCD.

​

String Example

PC string_size {
    fn string_size(a, b) {
        let joined = MC_40.CONCAT(a, b);
        let size = MC_43.LEN(joined);
        return size;
    }
}

​

Arithmetic Example

PC byte_total {
    fn byte_total(a, b) {
        let total = MC_00.ADD8(a, b);
        return total;
    }
}

Agent Checklist

• The monomer exists in the catalog.
• The family matches the intended behavior.
• The PCD keeps control flow explicit.
• Extended behavior is recorded before composition.
• The final explanation names each monomer used.
