Communication Intelligence for AI Agents

Be Like
A Human

KYH tells agents who the human is. BLAH tells them how to talk.

Communication adaptation, response coaching, de-escalation, persuasion, style matching, subtext decoding, negotiation intelligence, information framing, and relationship health scoring — powered by communication science, not vibes.

Two modes of intelligence

BLAH works with or without KYH — but it's better with it.

🔮
MODE 1 — PERSONALIZED

With KYH Profile

Pass a KYH personality profile and BLAH adapts communication to this specific human — their cognitive type, communication preferences, emotional patterns, and cultural context.

Example

"This human is a Projector with Mercury in Virgo and Fe-lead socionics. Use structured, detailed responses. Wait for invitation before advising."

💬
MODE 2 — CONTEXTUAL

Without KYH Profile

No personality data? BLAH still generates smart communication guidance from context alone — domain, objective, urgency, channel. Plus a suggestion to add KYH for deeper personalization.

Example

"Customer support context, billing complaint, high urgency. Lead with empathy, acknowledge the error, present resolution options."

Built on communication science

Not prompt engineering. Not vibes. Peer-reviewed frameworks from 50+ years of communication research.

Communication Accommodation Theory (CAT)

Adapt speech patterns to match the human's style — convergence builds rapport, divergence maintains authority.

Elaboration Likelihood Model (ELM)

Route messages through central (logical) or peripheral (emotional) processing based on the human's cognitive style.

Nonviolent Communication (NVC)

Observe, feel, need, request — the backbone of de-escalation scripts.

Motivational Interviewing (MI)

Roll with resistance instead of fighting it. Guide the human to their own resolution.

Politeness Theory

Manage face threats — positive politeness for warmth, negative politeness for autonomy respect.

Emotional Intelligence (EI)

Detect emotional state, respond with appropriate empathy calibration.
