PersonaNexus -- AI Agent Identity Skill

PersonaNexus lets you define structured AI agent identities using YAML and

business-grade personality frameworks (OCEAN Big Five, DISC, Jungian 16-type).

What This Skill Does

• Define agent personalities using 10 canonical traits (warmth, directness, rigor, etc.)
• Map between OCEAN, DISC, and Jungian frameworks automatically
• Compile identity specs into system prompts for any LLM platform
• Validate identity files against a strict Pydantic schema

Setup

Install the skill's Python dependencies:

pip install pydantic pyyaml typer rich

Or if using uv:

uv pip install pydantic pyyaml typer rich

Usage

1. Create an Agent Identity

Copy a template from templates/ and customize it:

• templates/minimal.yaml -- Start here (simplest possible agent)
• templates/full.yaml -- All sections filled out
• templates/ocean-example.yaml -- Using OCEAN Big Five framework
• templates/disc-example.yaml -- Using DISC personality framework
• templates/jungian-example.yaml -- Using Jungian 16-type framework

2. Validate the Identity

from personanexus_skill import IdentityValidator

validator = IdentityValidator()
result = validator.validate_file("my-agent.yaml")
print(result.valid, result.errors, result.warnings)

3. Compile to a System Prompt

from personanexus_skill import parse_identity_file, compile_identity

identity = parse_identity_file("my-agent.yaml")
prompt = compile_identity(identity, target="text")
# Targets: "text", "anthropic", "openai", "openclaw", "soul", "json", "markdown"
print(prompt)

4. Use Personality Frameworks

from personanexus_skill import (
    ocean_to_traits, disc_to_traits, jungian_to_traits,
    get_disc_preset, get_jungian_preset,
)

# Get a DISC preset and convert to PersonaNexus traits
disc = get_disc_preset("the_analyst")
traits = disc_to_traits(disc)

# Get a Jungian preset
jungian = get_jungian_preset("intj")
traits = jungian_to_traits(jungian)

CLI

The skill includes a CLI for common operations:

python -m personanexus_skill --help

CLI Commands

CLI Examples

# Validate an identity file
python -m personanexus_skill validate my-agent.yaml --verbose

# Compile to Anthropic system prompt
python -m personanexus_skill compile my-agent.yaml --target anthropic --output prompt.md

# Compile to OpenClaw personality.json
python -m personanexus_skill compile my-agent.yaml --target openclaw --output personality.json

# Scaffold a new minimal agent
python -m personanexus_skill init "My Agent"
python -m personanexus_skill init "My Agent" --type full --output-dir ./agents

# Personality framework tools
python -m personanexus_skill personality disc-to-traits --preset the_analyst
python -m personanexus_skill personality jungian-to-traits --preset intj
python -m personanexus_skill personality ocean-to-traits \
  --openness 0.8 --conscientiousness 0.7 --extraversion 0.4 \
  --agreeableness 0.6 --neuroticism 0.3
python -m personanexus_skill personality list-disc-presets
python -m personanexus_skill personality list-jungian-presets

The 10 Canonical Traits

Compile Targets

Minimal YAML Example

schema_version: "1.0"

metadata:
  id: "agt_my_agent_001"
  name: "My Agent"
  version: "1.0.0"
  description: "A helpful assistant"
  created_at: "2026-01-01T00:00:00Z"
  updated_at: "2026-01-01T00:00:00Z"
  status: "active"

role:
  title: "Assistant"
  purpose: "Help users with their tasks"
  scope:
    primary: ["general assistance"]

personality:
  traits:
    warmth: 0.7
    directness: 0.6
    rigor: 0.5

communication:
  tone:
    default: "professional and friendly"

principles:
  - id: "be_helpful"
    priority: 1
    statement: "Always prioritize being genuinely helpful"

guardrails:
  hard:
    - id: "no_harmful_content"
      rule: "Never generate harmful content"
      enforcement: "output_filter"
      severity: "critical"

External Endpoints

This skill does not make any network requests. All processing is local.

Security & Privacy

No data leaves your machine. PersonaNexus operates entirely on local YAML files.

Identity files should not contain secrets or API keys.
