# Simulator Effect Skill Specification
> *Implication is more efficient (and richer) than simulation.*
## Purpose
The Simulator Effect skill provides principles and methods for leveraging imagination -- human or LLM -- to fill gaps in sparse specifications. Instead of exhaustive simulation, provide seeds that activate rich mental models.
---
## Core Methods
### IMPLY
Instead of simulating, imply.
**Input:** Minimal specification (name, archetype, sensory details)
**Output:** Rich interpretation filling gaps coherently
```yaml
# Input
character:
archetype: "grizzled bartender"
# LLM interprets as
bartender:
name: Grim
appearance: weathered face, salt-and-pepper beard
manner: laconic, speaks in short sentences
knowledge: has seen every adventurer who passed through
secrets: knows where the treasure is, will not say
```
### SEED
Provide imagination seeds rather than exhaustive specification.
**Seed types:**
- **Archetype** -- "bartender", "sage", "trickster"
- **Sensory detail** -- "smells of woodsmoke"
- **Mystery** -- "the locked door no one mentions"
- **Tension** -- "she avoided his gaze"
- **K-line** -- "Sagittarius", "melancholy", "playful"
```yaml
room:
seeds:
archetype: "mysterious pub"
sensory: "warm despite the draft, old ale smell"
mystery: "the back room that requires proving yourself"
tension: "regulars glance at newcomers, then away"
```
### SPARSE
Deliberately omit details to invite imagination.
**Anti-pattern:**
```yaml
# Over-specified -- leaves nothing to imagine
room:
name: The Gezelligheid Grotto
tables: 12 oak tables, 3 round, 9 rectangular
chairs: 48 chairs, mix of styles
bar: 15 feet long, mahogany with brass rail
taps: 8 beer taps, 2 cider, 1 mead
lighting: 6 candelabras, 12 wall sconces
floor: wide oak planks, worn in traffic paths
# ... 50 more lines
```
**Pattern:**
```yaml
# Sparse -- imagination fills the rest
room:
name: The Gezelligheid Grotto
atmosphere: warm despite the draft
smell: woodsmoke and old ale
notable: the back room no one talks about
```
### ARCHETYPE
Use cultural archetypes as shorthand for personality packages.
**Archetype categories:**
| Category | Examples | What They Activate |
|----------|----------|-------------------|
| Zodiac | Sagittarius, Cancer | Full personality clusters |
| Role | Bartender, Sage, Trickster | Behavioral expectations |
| Species | Dog, Cat, Monkey | Disposition, physicality |
| Profession | Detective, Librarian, Chef | Knowledge, methods |
| Trope | Grizzled veteran, Naive newcomer | Story function |
```yaml
# One word does the work of a personality matrix
character:
archetype: sagittarius_explorer
# Implies: adventurous, philosophical, blunt, optimistic
```
### JAZZ
Use YAML comments as imagination seeds (per [yaml-jazz](../yaml-jazz/)).
```yaml
playful: 9
# not born playful -- BECAME playful by choice
# 122 years of grim taught me joy is rebellion
melancholy: 6
# higher than I first admitted
# the silver streaks glow when I am sad
```
Comments are read by the LLM. They shape interpretation. They are not documentation -- they are code.
---
## The Astrillogical Pattern
Named after The Sims' zodiac implementation (1997):
1. **Compute something minimal** (Euclidean distance to archetype vectors)
2. **Display a cultural symbol** (zodiac icon)
3. **Write no behavioral code**
4. **Let imagination do the rest**
Result: Testers reported the zodiac was "too influential" -- but there was no influence to tune. The effect was purely imagined.
**Application:**
```yaml
# Minimal computation
character:
personality_vector: [neat: 7, outgoing: 3, playful: 9]
# Display nearest archetype
archetype: sagittarius # Computed, not assigned
# No behavioral code referencing 'sagittarius'
# Player/LLM imagines Sagittarius behavior
```
---
## Integration with Other Skills
### With k-lines/
Names activate clusters. Simulator Effect explains why.
```yaml
# K-line activation IS Simulator Effect
character:
name: Palm # Activates: open hand, tropical, reaching
```
### With adversarial-committee/
Mode-collapse is Simulator Effect in reverse -- LLM collapses to mean when constraints are absent. Adversarial committee provides constraints through opposing propensities.
```yaml
committee:
- propensity: paranoid_realism # Different lens
- propensity: idealism # Different lens
- propensity: evidence_prosecutor # Different lens
# Same topic, three different Simulator Effects
# Cross-examination finds robust interpretations
```
### With speed-of-light/
One LLM call, many turns. Imagination fills the "rendering" for each turn. Sparse state, rich narrative.
### With needs/
Sims motives are imagination seeds, not behavior code.
```yaml
needs:
hunger: 30 # Seed
# LLM imagines: "distracted by stomach growling"
# Not: deterministic eat() behavior
```
### With empathic-templates/
Templates leverage Simulator Effect -- provide structure, let LLM fill content.
```yaml
template: |
[CHARACTER] enters [ROOM] and notices [NOTABLE_DETAIL].
They feel [EMOTION] because [REASON].
# LLM generates coherent fill based on context
```
---
## Failure Modes
### Over-Specification
Too much detail leaves nothing to imagine. The simulation feels mechanical.
**Symptom:** Output feels like a checklist, not a story.
**Fix:** Remove 80% of specification. Keep seeds.
### Under-Seeding
Not enough anchors for imagination to grip.
**Symptom:** Output is generic, could be anyone/anywhere.
**Fix:** Add archetype, sensory detail, or mystery.
### Wrong Archetype
Archetype conflicts with intended behavior.
**Symptom:** Character behaves "off" despite correct specs.
**Fix:** The archetype K-line is overriding your specs. Change the archetype or add explicit counters.
### Mode-Collapse
Single-agent LLM with weak constraints collapses to bland mean.
**Symptom:** Output is safe, inoffensive, boring.
**Fix:** Use adversarial-committee or add tension/conflict seeds.

## Metrics
The Simulator Effect is working when:
1. **Readers imagine more than you wrote**
2. **LLM generates coherent detail you did not specify**
3. **Different interpreters imagine similar worlds**
4. **Sparse specs produce rich output**

*"The game provides scaffolding. Imagination does the rendering."*
This skill shows how to use implication and minimal seeds to trigger rich imagination instead of exhaustive simulation. It teaches patterns for giving just enough cultural, sensory, and mystery cues so humans or LLMs fill in coherent, evocative detail. The goal is lean specifications that produce rich, varied interpretations.
Provide sparse inputs—archetypes, sensory notes, tensions, or short comments—that act as imagination seeds. The LLM or reader uses those seeds to infer character, setting, and behavior rather than following deterministic simulation rules. Techniques include IMPLY (expand from minimal prompts), SEED (supply compact cues), SPARSE (omit detail deliberately), ARCHETYPE (use cultural shorthand), and JAZZ (comments as active seeds).
What if the LLM ignores my seed and outputs bland text?
Add a stronger anchor: an archetype, a sensory detail, or a tension. If needed, run an adversarial-committee or present contrasting propensities to force distinctive lenses.
How sparse is too sparse?
Too sparse yields generic output. Aim for 1–3 high-signal seeds (archetype, sensory, or mystery). If outputs are vague, add one more concrete cue.
