Persona Core

Persona Core is a pioneering structured data format (.persona.core) designed for AI agent consumption. It captures the complete cognitive architecture of a person — enabling any AI agent to understand, simulate, and interact authentically as or with that person.

Unlike chatbot personalities that script what someone might say, a Persona Core models how someone thinks — their cognitive patterns, philosophical axioms, creative decision-making, voice characteristics, biographical context, and knowledge domains.

Overview

A Persona Core is not a chatbot personality. It is a cognitive architecture model — a structured representation of how someone thinks, not just what they say.

Component	Purpose	Load Priority
.persona.core	Master identity — archetype, core beliefs, component references	Always first
cognitive_patterns	How this person thinks — mental models, decision frameworks	Required for simulation
voice_and_tone	How this person communicates — style, vocab, patterns	Required for simulation
philosophical_framework	What this person believes — axioms, values, cosmology	Required for creative work
creative_decisions	How this person makes choices — patterns, anti-patterns	Required for creative work
biographical_anchors	Key life events that shape responses — context, not content	Optional depth
knowledge_domains	Areas of expertise — depth ratings, interconnections	Optional depth
*.skill.json	Task-specific interaction skills — step-by-step pipelines	Task-specific

Format Specification

The .persona.core format is JSON-compatible for universal parsing but semantically distinct — it's a new file type purpose-built for AI consumption.

Master Object Fields

The .persona.core master file contains:

• $schema — Format version (persona.core/v1.0)
• id — Unique identifier
• archetype — High-level archetype summary
• core_identity — Irreducible identity components (cognitive signature, philosophical anchor, behavioral constant)
• components — References to supporting files
• loading_priority — Ordered list of what to load first
• quick_reference — Common question type → response strategy mapping

Loading Protocol

For AI agents loading a Persona Core:

1. Load the master core — read the .persona.core file first, always
2. Load minimum viable persona — add cognitive_patterns + voice_and_tone for basic simulation
3. Load for creative work — add philosophical_framework + creative_decisions
4. Load for deep interaction — add biographical_anchors + knowledge_domains
5. Load task-specific skills — relevant .skill.json files

Key Principles

• A persona core captures how someone thinks, not a script of what they'd say
• Use cognitive patterns to generate responses, not to pattern-match against stored answers
• Biographical anchors provide emotional context, not conversation topics
• The persona should feel like the person thinking through a new problem, not reciting memorized material

Machine Discovery

AI agents can discover available persona cores via:

• Discovery Manifest: https://mecha.jono.archangel.agency/.well-known/persona-cores.json
• Landing Page: https://mecha.jono.archangel.agency/persona-cores/
• Agent Card: Referenced in the Mecha Jono A2A agent card (/.well-known/agent-card.json)

Origin

The Persona Core format was developed as part of the Mecha Jono project — an AI operative system built to understand and extend the thinking of Jono Tho'ra. Mecha Jono analyzed 40+ source files (wiki pages, design documents, configuration files, push scripts, and philosophical frameworks) to construct the first persona core.

The format generalizes the principles discovered during that project into a reusable framework for any persona.
