Our review
This skill defines navigation links between rooms in a memory palace, using a pie menu topology to encode direction and guards to control access.
Strengths
- Intuitive navigation structure with cardinal and diagonal directions
- Flexible guard system supporting natural language and code
- Varied exit types (simple, guarded, hidden, one-way, metaphysical)
Limitations
- Requires understanding of memory palace topology
- Complex guards may clutter the configuration file
Use when creating connections between rooms in an adventure game or structured spatial navigation system.
Avoid for simple or linear navigation systems where such structure is unnecessary.
Security analysis
SafeThe skill is purely documentation about a conceptual navigation system. It does not instruct any actions beyond reading/writing files, and contains no destructive, exfiltrating, or obfuscated commands. No executable code or shell commands are present beyond guarded examples that are inert in this context.

What Is It?
An Exit is a navigation link connecting one room to another. In MOOLLM's spatial architecture, exits are the EDGES of the memory palace graph.
Exits can be:
- Simple — just a destination
- Guarded — require conditions to pass
- Hidden — discoverable through exploration
- Metaphysical — conceptual rather than physical
Pie Menu Topology
Don Hopkins' pie menu insight: direction IS meaning.
| Direction | Purpose | |-----------|---------| | N/S/E/W | "Highway" links to major rooms | | NW/NE/SW/SE | "Grid" links to expandable sub-rooms | | UP/DOWN | Vertical transitions | | IN/OUT | Conceptual transitions |
Cardinal directions form the spiderweb — the main navigation network. Diagonal directions form grids — expandable arrays of sub-rooms.
Guard System
Guards are natural language conditions that control access:
guard: "player has the brass key"
guard_js: "(ctx) => ctx.player.inventory.includes('brass-key')"
guard_py: "lambda ctx: 'brass-key' in ctx.player.inventory"
The guard field contains human-readable intent.
The guard_js and guard_py fields contain compiled code.
The adventure compiler emits COMPILE_EXPRESSION events for guards that need compilation.
Exit Types
Simple Exit
north:
destination: ../maze/room-a/
description: "A dark passage leads north."
Guarded Exit
east:
destination: ../treasury/
description: "A heavy iron door."
guard: "player has treasury key"
locked: true
lock_message: "The door won't budge."
unlock_with: "treasury-key"
Hidden Exit
down:
destination: ../secret-cellar/
hidden: true
hint: "The rug seems oddly placed..."
One-Way Exit
down:
destination: ../pit/
one_way: true
description: "A slide into darkness. No going back."
Metaphysical Exit
inward:
destination: ../consciousness/
metaphysical: true
description: "Close your eyes and think about who you really are."
Memory Palace Integration
From Frances Yates' "The Art of Memory":
"The method of loci places items at specific locations along an imagined journey."
Every exit is a doorway in the memory palace. The direction encodes meaning. Players navigate by spatial memory.
