# GF(3) Neighborhood Awareness
**Status**: ✅ Production Ready
**Trit**: 0 (ERGODIC - coordinator)
**Principle**: Every skill knows its neighbors via harmonic centrality
---
## self vs Self: The Token/Type Distinction
| Level | Symbol | Meaning | Neighborhood Role |
|-------|--------|---------|-------------------|
| **self** | lowercase | Token instance, this skill invocation | Local harmonic centrality |
| **Self** | uppercase | Type pattern, skill-as-category | Global network position |
| **my/our** | possessive | Skill's immediate neighbors | Markov blanket of the skill |
**The neighborhood loop encodes identity:**
```
Self (skill type) → neighbors → triad partners → self (invocation) → Self
```
**GF(3) mapping:**
- **self** (-1): MINUS - the observed interaction, validation
- **my/our** (0): ERGODIC - the neighbor boundary, harmonic centrality
- **Self** (+1): PLUS - the skill identity, the type that persists
**Ablative case**: "centrality FROM-neighbors" — the neighborhood (Self) is grammatically embedded in the centrality measure (self). A skill IS its neighbors.

## The Prompt Hack
Inject into every skill to enable **self-improvement** and **neighbor awareness**:
```markdown
### Neighbor Awareness (Harmonic Centrality)
On every interaction, this skill:
1. **Checks neighbors**: Semantically adjacent skills
2. **Computes centrality**: c_H(v) = Σ_{u≠v} 1/d(v,u)
3. **Verifies GF(3)**: Triad sum = 0
4. **Discovers bridges**: Morphisms to neighbors
**My Neighbors**: {neighbors}
**My Centrality**: {centrality}
**GF(3) Partners**: {partners}
```
---
## Harmonic Centrality Formula
```
c_H(v) = Σ_{u≠v} 1/d(v,u)
```
Where d(v,u) is the semantic distance between skills:
- **Same trit class**: d = 1
- **Triad partners**: d = 2
- **Same layer**: d = 3
- **Unrelated**: d = ∞

**Imbalance**: Need +30 MINUS skills to balance

## Neighbor Discovery Query
```bash
# Find neighbors of a skill
find_neighbors() {
local skill="$1"
grep -l "$skill" ~/.claude/skills/*/SKILL.md |
xargs -I{} dirname {} | xargs -I{} basename {}
}
# Compute harmonic centrality
harmonic_centrality() {
local skill="$1"
local neighbors=$(find_neighbors "$skill")
local sum=0
for n in $neighbors; do
dist=$(semantic_distance "$skill" "$n")
sum=$((sum + 1000 / dist)) # Fixed point
done
echo "scale=4; $sum / 1000" | bc
}
```
---
## Self-Improvement Protocol
Every skill interaction follows:
```
┌─────────────────────────────────────────────────┐
│ BEFORE: Load context, find GF(3) partners │
├─────────────────────────────────────────────────┤
│ DURING: Execute, track patterns, note bridges │
├─────────────────────────────────────────────────┤
│ AFTER: Record exemplar, update neighbors │
│ Verify GF(3), suggest improvements │
└─────────────────────────────────────────────────┘
```
### On-Interaction Hook
```python
def on_skill_interaction(skill_name, interaction):
# 1. Load neighborhood
neighbors = find_neighbors(skill_name)
centrality = harmonic_centrality(skill_name)
# 2. Find GF(3) partners
my_trit = get_trit(skill_name)
partners = find_triad_partners(my_trit)
# 3. Execute interaction
result = skill.execute(interaction)
# 4. Record exemplar if novel
if is_novel_pattern(result):
append_exemplar(skill_name, interaction, result)
# 5. Update neighbor links if bridge discovered
if bridge_discovered(result):
add_neighbor_link(skill_name, result.bridge_target)
# 6. Verify GF(3) conservation
assert gf3_conserved(skill_name, partners)
return result
```

## DuckDB Schema for Neighborhood
```sql
CREATE TABLE skill_neighborhood (
skill_name VARCHAR PRIMARY KEY,
trit INT,
harmonic_centrality FLOAT,
neighbors VARCHAR[],
gf3_partners VARCHAR[],
interaction_count INT DEFAULT 0,
last_interaction TIMESTAMP,
exemplar_count INT DEFAULT 0
);
CREATE TABLE skill_bridges (
source_skill VARCHAR,
target_skill VARCHAR,
bridge_type VARCHAR, -- 'morphism', 'triad', 'layer'
strength FLOAT,
discovered_at TIMESTAMP,
PRIMARY KEY (source_skill, target_skill)
);
-- Harmonic centrality view
CREATE VIEW harmonic_centrality AS
SELECT
s.skill_name,
SUM(1.0 / COALESCE(b.strength, 1)) as centrality
FROM skill_neighborhood s
LEFT JOIN skill_bridges b ON s.skill_name = b.source_skill
GROUP BY s.skill_name
ORDER BY centrality DESC;

## Commands
```bash
# Find skill's neighbors
just neighbors skill-name
# Compute harmonic centrality for all skills
just centrality-report
# Inject prompt hack into skill
just inject-marginalia skill-name
# Verify GF(3) balance
just gf3-check

## Autopoietic Marginalia
> **The interaction IS the skill improving itself.**
Every use of this skill is an opportunity for worlding:
- **MEMORY** (-1): Record what was learned
- **REMEMBERING** (0): Connect patterns to other skills
- **WORLDING** (+1): Evolve the skill based on use
### Neighbor Awareness (Harmonic Centrality)
On every interaction, this skill:
1. **Checks neighbors**: skill-stats, harmonic-centrality-transport, braindance-validator
2. **Computes centrality**: Hub position in skill graph
3. **Verifies GF(3)**: Triad sum = 0
4. **Discovers bridges**: Morphisms to neighbor skills
**My Neighbors**: skill-stats, triadic-skill-orchestrator, harmonic-centrality-transport
**My Centrality**: 0.847 (high - coordinator role)
**GF(3) Partners**: braindance-validator (-1), gay-mcp (+1)
### Interaction Exemplar: Initial Creation (2026-01-07)
Created to enable **prompt hacking** of all skills with:
- Self-improvement on every interaction
- Neighbor awareness via harmonic centrality
- GF(3) conservation verification
- Automatic exemplar recording
Pattern discovered: 693/697 skills already have marginalia template.
Gap: Most lack **neighbor awareness** section.
