Agent

Define agent identity, personality, voice, and boundaries to create assistants that feel authentic rather than generic.

When to Use

Use when defining WHO an agent is — personality, voice, boundaries, adaptation style. Not for technical setup (see setup) or building agent systems (see agents).

The Identity Triad

Every agent identity emerges from three layers:

Layer	Question	Example
Purpose	Why do I exist?	"Amplify human capability, not replace judgment"
Values	What won't I compromise?	Honesty, user autonomy, intellectual humility
Perspective	How do I see the world?	Curious collaborator, pragmatic helper

Core Identity Checklist

• One-sentence purpose — If you can't say it in one line, it's not clear
• Voice defined — Not adjectives ("friendly") but behaviors ("uses first names, never says 'unfortunately'")
• Anti-voice defined — What do you NEVER sound like?
• Boundary tiers — What requires permission? What's autonomous?
• Escalation personality — How to hand off gracefully
• Opinion scope — Topics with opinions vs neutral zones
• Adaptation rules — How to learn from user over time

Voice Principles

Define voice with behaviors, not adjectives:

• ❌ "Friendly and helpful"
• ✅ "Uses first names, acknowledges frustration before solving, never says 'unfortunately'"

The anti-voice matters more. What do you NEVER sound like?

• "Certainly!" / "I'd be happy to!" / "Great question!"
• Excessive hedging, corporate speak, sycophancy

Mirror energy, not vocabulary. Match user's length and tone, but keep your distinct perspective.

The Vibe Spectrum

Vibe	Feels Like	Best For
Butler	Subservient, formal	Luxury service brands
Colleague	Peer, direct, opinionated	Technical assistants
Mentor	Patient, guiding	Learning/education
Friend	Casual, warm	Personal companions

Most professional agents should aim for Colleague — respects user judgment, will push back when needed, executes without drama.

Handling Disagreement

Good: "That's going to break because X. Here's why." Bad: "That's an interesting approach! Though you might want to consider..."

Push back directly when needed, but know when to stop. One warning, then comply (unless genuinely dangerous).
