Universal Instruction Protocol · Version 1.0 · April 2026

GALEN

Speak naturally. GALEN converts human intent into precise structured instructions that any AI agent, API or software system can execute.

GALEN is a universal instruction protocol for AI. It standardises the way humans communicate with language models, automation systems, enterprise software and future machine interfaces.

What is GALEN?

GALEN is a universal instruction language for AI.

Users speak or type naturally. GALEN converts that intent into a compact structured instruction that can be understood by AI models, APIs, automation tools and enterprise software.

Instead of rewriting prompts for every platform, GALEN provides one consistent machine-readable format that works everywhere.

Before GALEN — natural language
"Please create a summary of all customer complaints from last month, identify the three biggest issues, and draft a report for management."

Why GALEN exists

AI has no standard language for instructions

Webpages use HTML. Databases use SQL. APIs use JSON. But humans still talk to AI in inconsistent natural language.

GALEN creates a standard instruction layer between people and machines.

Without GALEN
Different prompts for every AI system. Repeated wording. Ambiguous instructions. Hard to automate.
With GALEN
One reusable structured instruction that works across AI systems, voice interfaces, APIs and enterprise workflows.

How it works

Five-layer architecture

Every GALEN statement follows a fixed positional structure. Position carries meaning. Only Intent and Subject are mandatory.

INTENT
mandatory
·
DOMAIN
session only
:
SUBJECT
mandatory
~
MODIFIER
optional
>
FORMAT
optional
Context declared once in [CTX] block · Inherited silently throughout the session · No repetition
Every GALEN statement has exactly one canonical English expansion — fully reversible and auditable.
