# Relationship Astrology — Agent Interpretation Guide

> For agents using the astro MCP to perform relationship chart interpretation.

## Overview

Relationship astrology uses four main techniques to analyze the dynamics between two people:

| Technique | What It Shows |
|---|---|
| **Synastry** | Interaction patterns — how Person A's planets trigger Person B's planets |
| **Composite Chart** | The relationship as its own entity — structure, identity, public face |
| **Davison Chart** | The relationship's "birth" — inner experience, emotional tone, long-term evolution |
| **Coalescent Chart** | Harmonic responsiveness to transits (rarely used) |

**For serious analysis, use all three main techniques plus natal charts.** They are complementary layers, not competing methods.

## Reading Workflow

### Step 1: Natal Charts
Understand each person individually first. What are their core needs, attachment styles, relationship patterns? This provides context for everything that follows.

### Step 2: Synastry
Analyze the **interaction patterns** between the two charts:
- Tightest interchart aspects (tightest orbs = most significant)
- Venus-Mars contacts (chemistry)
- Moon contacts (emotional bonding)
- Saturn contacts (commitment, karma, heaviness)
- Node contacts (fated connections)
- House overlays (which life areas are activated)

### Step 3: Composite Chart
Analyze the **relationship as its own entity**:
- Composite Sun (identity and purpose)
- Composite Moon (emotional tone)
- Angular planets (loudest voices)
- Key aspect patterns (especially Saturn, Pluto, Neptune)
- House emphasis (life area of focus)

### Step 4: Davison Chart
Analyze the **relationship's inner experience**:
- Same approach as composite but focused on emotional/internal tone
- More accurate for timing techniques (progressions, solar arcs)
- Use for long-term evolution tracking

### Step 5: Synthesis
Find **repeated themes** across synastry + composite + Davison. These recurring patterns are the core narrative of the relationship.

## Synastry Interpretation

### Key Principle
Each person **plays the role** of their planet in an interchart aspect. If A's Saturn conjuncts B's Sun, A takes on the Saturn role when B expresses Sun qualities. Think of it as a dance where each person activates different roles depending on context.

### Interchart Aspects: Quick Reference

#### Venus-Mars (Chemistry)
| Aspect | Meaning |
|---|---|
| Conjunction | Intense, obvious physical and romantic attraction |
| Trine/Sextile | Desire and affection flow easily; compatible sexual needs |
| Opposition | Strong magnetism with push-pull dynamics |
| Square | Highly stimulating but prone to friction and fights |

#### Moon-Venus (Emotional Warmth)
- Creates tenderness, caring, feeling emotionally "fed" by partner
- One of the best aspects for domestic comfort and feeling cherished
- Conjunction, trine, sextile = easy flow; hard aspects = needs clash

#### Sun-Moon (Core Compatibility)
- Deep understanding at ego and emotional levels
- Conjunction/trine/sextile: natural "getting" of each other
- Opposition: complementary but different needs
- Square: intense attraction with emotional friction

#### Saturn Aspects (Commitment and Karma)
- Conjunctions feel fated, dutious, sometimes heavy
- Trines/sextiles provide stability and reliability
- Squares/oppositions bring tests, delays, pressure
- Not inherently bad — many long marriages have strong Saturn contacts

#### Node Contacts (Fated Connections)
- Planets on North Node: destined connection, growth catalyst
- Planets on South Node: "known you forever" past-life feel
- Saturn on North Node: karmic teacher relationship
- Saturn square Nodes: karmic block, timing challenges

### House Overlays
When Planet A falls in Planet B's house:
- **1st house**: Strongly visible, shapes self-image
- **4th house**: Emotional significance, feeling "at home"
- **7th house**: Partnership significance, embodies relating energy
- **8th house**: Intense psychological/sexual bond
- **10th house**: Public significance, affects career
- **12th house**: Hidden or spiritual connection, can be confusing

### Orb Guidelines
- Personal planets (Sun through Saturn): 5° max
- Outer planets: 3° max
- Tighter orbs = stronger effect
- Using significance scoring: conjunction/opposition > square > trine > sextile

## Composite Chart Interpretation

### Key Principle
**The composite chart describes the relationship entity, not either person.** Composite Moon in Scorpio doesn't mean either person is emotionally intense — it means the *relationship itself* has that quality.

### Reading Order
1. **Chart shape**: House clusters (upper/lower, east/west hemispheres)
2. **Composite Ascendant**: How the relationship presents itself
3. **Composite Sun**: Relationship identity and purpose
4. **Composite Moon**: Emotional tone
5. **Angular planets**: Loudest voices
6. **Most-aspected planet**: Recurring theme
7. **Unaspected planets**: Blind spots
8. **Chart ruler**: How the relationship navigates challenges

### Composite Planet Meanings
| Planet | Meaning in Composite |
|---|---|
| Sun | Core identity and purpose of the relationship |
| Moon | Emotional tone, comfort, daily rhythms |
| Mercury | Communication style as a couple |
| Venus | Love style, affection, shared values |
| Mars | Drive, passion, conflict style |
| Jupiter | Growth, optimism, shared beliefs |
| Saturn | Structure, commitment, tests |
| Uranus | Unpredictability, freedom, innovation |
| Neptune | Idealism, spiritual connection, illusion |
| Pluto | Power dynamics, transformation, depth |

### Composite Aspects
- **Orbs**: 3° max (tighter than natal). Sub-1° = defining feature.
- **Saturn aspects**: Structural foundation. No Saturn = free but unstable. Strong Saturn = enduring but demanding.
- **Pluto aspects**: Power struggles and transformation potential.
- **Neptune aspects**: Idealization risk. Watch for disillusionment when glamour fades.
- **Sun-Saturn conjunction**: Core defining feature — serious but potentially very long-lasting.

### Common Mistakes
1. Reading composite as a natal chart for one person
2. Treating difficult aspects as relationship doom
3. Reading composite in isolation (always use with synastry + natal)

## Davison Chart Interpretation

### Technical Note
The Davison chart is a **real chart at a real moment in time** (midpoint of two births), unlike the composite which is purely symbolic. This means it can be progressed and directed like a natal chart.

### Composite vs. Davison
| | Composite | Davison |
|---|---|---|
| Nature | Symbolic blueprint | Real moment in space/time |
| Shows | Structure, public face | Inner tone, emotional experience |
| Best for | How relationship functions | How it feels and evolves |
| Timing | Transits | Transits + progressions + solar arcs |

### Practical Staging
- **Synastry** → when people first meet
- **Composite** → once relationship forms
- **Davison** → once formally committed

### When They Differ
Look for **repeated themes** across both. They are "two versions of the same story." Same planets emphasized, similar house themes = core relationship narrative confirmed.

## Relationship Type Indicators

### Romantic / Sexual
- Venus-Mars aspects (synastry + composite)
- 5th and 8th house emphasis
- Moon contacts for emotional bonding
- Saturn contacts for commitment
- Pluto contacts for intensity

### Business / Professional
- Mercury contacts for communication
- 6th and 10th house emphasis
- Saturn contacts for structure
- Jupiter contacts for growth
- Uranus contacts for innovation

### Family Dynamics
- Moon contacts for emotional patterns
- 4th house emphasis
- Saturn contacts for duty/parental roles
- Node contacts for karmic family patterns

### Friendships
- Mercury contacts for intellectual connection
- 11th house emphasis
- Jupiter contacts for shared optimism
- Uranus contacts for unconventional bonds

---

## Timing Relationship Events

### Composite/Davison Transits
- **Saturn transits** to composite angles: Tests and restructuring
- **Jupiter transits** to composite angles: Expansion and growth
- **Uranus transits**: Sudden changes, disruption
- **Pluto transits**: Deep transformation
- **Eclipses** hitting composite angles: Fateful turning points

### Transit Preview
Use the astro MCP's transit preview capability on the composite and Davison charts to identify windows of activation.

## Karmic Relationship Indicators

(See karmic-agent-GUIDE.md for full detail)

### Key Indicators Across All Three Layers
- Saturn-Node contacts between charts (karmic contracts)
- Pluto-South Node contacts (intense past-life patterns)
- Composite/Davison chart emphasizing 8th house (shared transformation)
- South Node contacts suggesting familiarity from past lives
- Saturn-heavy composites suggesting serious, destiny-laden relationships

## Synthesis: Building the Narrative

When synthesizing a relationship reading across all layers:

1. **Identify the core narrative** — What story do all three layers tell together?
2. **Note contradictions** — Where do the layers diverge? These are areas of complexity.
3. **Assess karmic weight** — How many karmic indicators are present? (Saturn, Pluto, Nodes)
4. **Determine relationship type** — Romantic, karmic, business, casual, fated?
5. **Identify growth edges** — What are the challenging aspects teaching?
6. **Check timing** — What transits are activating the relationship now or soon?

### Output Structure for Agents
A good relationship analysis output should include:
- **Overview**: Core narrative in 2-3 sentences
- **Synastry highlights**: Top 5-7 interchart aspects with interpretation
- **Composite reading**: Relationship identity, strengths, challenges
- **Davison reading** (if calculated): Inner emotional experience
- **Karmic indicators**: Any significant past-life or soul-contract themes
- **Current transit influences**: What's activating the relationship right now
- **Guidance**: What each person can do to support the relationship's growth
