Our review
This skill defines navigation links between rooms of a memory palace, using a pie-menu topology and a guard system for conditional access.
Strengths
- Enables complex and meaningful navigation structures.
- Integrates natural language guards and programmable conditions.
- Supports various exit types (simple, hidden, one-way, metaphysical).
- Draws on memory palace principles for intuitive navigation.
Limitations
- YAML configuration can become verbose for many links.
- Guards require programming logic for advanced conditions.
- Spatial metaphor may not fit all contexts.
Use this skill when designing a spatial navigation environment with semantic directions, such as an adventure game or mental organization tool.
Avoid this skill for simple or flat navigation systems, or when the memory palace metaphor is not applicable.
Security analysis
SafeThe skill is a documentation file describing game navigation concepts. It only uses read_file and write_file, and does not instruct any destructive, data-exfiltrating, or unsafe actions. No risky code execution or obfuscated payloads.

Exit
"Every exit is a promise of adventure." — The Rusty Lantern Guest Book
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.
