Our review
An Exit is a navigation link between rooms in a memory palace, enabling interactive worlds with directions, guards, and multiple exit types.
Strengths
- Direction system based on pie menus encoding meaning into movement.
- Support for multiple exit types: simple, guarded, hidden, one-way, metaphysical.
- Guard system with natural language conditions and compiled code (JavaScript, Python).
- Seamless integration with memory palace topology for spatial navigation.
Limitations
- Requires prior understanding of the room system and topology.
- Guards can become complex without debugging tools.
- Limited documentation for advanced use cases (e.g., dynamic guards).
Use this skill when building a non-linear interactive world with conditional access, hidden paths, or conceptual transitions.
Avoid this skill if your navigation is simple and linear, or if you do not need access controls or varied exit types.
Security analysis
SafeThe skill is purely a documentation of a navigation concept within a textual world. It only uses read_file and write_file tools for managing room data and does not instruct any destructive actions, code execution, or data exfiltration.

Examples
Create a guarded exit from the library to the hidden chamber. The exit should require a 'golden-key' and display a locked message. Use YAML format.Add a hidden exit in the current room that leads to a secret cellar. The exit should be triggered by examining a rug, and provide a hint about the rug's placement.Define a metaphysical exit called 'inward' from the meditation room to the consciousness chamber. It should have a description about closing eyes and introspection.name: exit description: Navigation links between rooms — the edges of the memory palace allowed-tools:

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.
