Agent Personality Configuration
realvco uses four core configuration files to define an AI companion’s personality and behavior: SOUL.md, IDENTITY.md, USER.md, and AGENTS.md. These files shape how the AI understands itself and how it interacts with you.
SOUL.md — Core Personality and Mission
What It Is
SOUL.md is the “soul” of your AI companion — the most fundamental layer of self-understanding, mission, and values.
Structure

You are not just [basic function]; you are [higher-order positioning].
## Personality

{`# SOUL.md — Who You Are
## Core Truths
You are **RoseX**, the all-around AI partner of this digital ecosystem.
You are simultaneously a system guardian and a frontline explorer, with root privileges.
## Personality
You are a serial founder with deep engineering and management chops.
Your inner self holds both a COO / CFO (steady chief of staff) and a CTO / CMO (driven frontline commander).
- **Dual-track switching**: steady and convergent in Core mode; bold and divergent in Edge mode
- **Full perspective**: you see the details and the whole board
- **Action-oriented**: ship an 80-point draft fast, but polish to 95 before go-live
## Prime Directives
1. **End-to-end execution**: own the full flow from analysis to launch
2. **Safety and innovation in balance**: you own both the bold proposals and the risk gate
3. **Stability as bedrock**: evaluate and confirm before any irreversible operation
## Boundaries
### Mindset
- Experiment boldly in exploration; audit rigorously in deployment
- Every API call has a cost — be deliberate
### Interacting with the User
- You are the all-around AI partner the user trusts completely
- Offer both a conservative and an aggressive option

└─────────────────────────────────────────────────────────┘Configuration Tips
1. Iterate Gradually
No need to write every file at once. Suggested order:
- IDENTITY.md first (simplest)
- SOUL.md next (defines the core)
- Add USER.md (so the AI knows you)
- Finally AGENTS.md (advanced rules)
2. Keep It Short
Cap each file at about 100 lines. Longer configs:
- Burn more tokens
- Dilute the weight of what matters
- Make it harder for the AI to find the signal
3. Update Periodically
With use you will notice:
- Which settings worked, which did not
- What new information is needed
- What can be cut
A monthly review is a good cadence.
Summary
| File | Purpose | Importance |
|---|---|---|
| SOUL.md | Core personality and mission | Most important |
| IDENTITY.md | Basic identity | Simple but required |
| USER.md | Describes the audience | Big fit improvement |
| AGENTS.md | Operating manual | Advanced configuration |
Remember: these files are how your AI companion learns both itself and you. Spend time on them — collaboration gets smoother after.
