Adventure

“Every directory is a room. Every file is a clue. Navigation is investigation.”

Turn exploration into a quest — or any simulation into a hybrid LLM/deterministic CLI.

Lineage: Colossal Cave (Crowther & Woods), Scott Adams Adventures, Zork (Infocom), MUD (Bartle), LambdaMOO (Curtis).

Inherits from: simulation/ — all simulation properties plus adventure-specific state.

[!TIP] This is a general pattern. Text adventure is the reference implementation, but the same architecture powers city sims, cloud management tools, board games — anything where deterministic transforms meet creative narration.

[!TIP] Perfect for codebase archaeology. “Find where the auth bug was introduced” — that’s a quest!

The Premise

An adventure creates a player with state, places them in a room, and the LLM dungeon masters them around.

# player.yml
name: Alice
location: entrance-hall
inventory:
  refs:                                    # Lightweight pointers (weight: 0)
    - pub/bar/brass-lantern.yml
    - street/acme-catalog.yml#portable-hole
  objects:                                 # Deep copies (has weight)
    - { id: notebook, name: "Notebook", weight: 0.5 }
  fungibles:                               # Stacks
    - { proto: economy/gold.yml, count: 50 }
health: 100
notes: "Looking for the lost artifact"

Inventory Protocol: See skills/inventory/ for full TAKE/DROP/BOX/BEAM operations, pointer syntax, and structural editing.

The core loop:

User: "go north"
  → DM: Updates player.location, describes the new room
User: "look around"
  → DM: Reads room YAML, narrates contents atmospherically  
User: "take the rusty key"
  → DM: Moves key to player.inventory, narrates the action

The mapping:

• Directories = Rooms to enter
• Files = Clues, artifacts, characters
• player.yml = Your state (location, inventory, health)
• Chat = How you control your character
• LLM = Dungeon Master (narrates, adjudicates, surprises)

This is Memory Palace with narrative framing and a player character.

Multi-User, Multi-Agent (Engelbart NLS tradition)

Naturally supports multiple simultaneous participants:

# characters/
├── alice.yml        # Human player 1
├── bob.yml          # Human player 2  
├── merchant.yml     # NPC (DM-controlled)
├── guard-bot.yml    # Autonomous bot (action queue)
└── oracle.yml       # LLM agent with own goals

Character types:

All coexist in the same world:

# library/ROOM.yml
occupants:
  - alice          # Player exploring
  - bob            # Another player
  - librarian      # NPC who answers questions
  - dust-sprite    # Bot that cleans autonomously

Selection: Current Character or Swarm (Sims/Populous tradition)

Like The Sims and Populous, you have a selection — who you’re controlling right now:

selection:
  mode: single          # or: group, swarm
  current: alice        # commands go to Alice
  
# Or control multiple at once:
selection:
  mode: group
  current: [alice, bob, charlie]  # "go north" moves all three
  
# Or a whole swarm (Populous/Dungeon Keeper style):
selection:
  mode: swarm
  filter: { type: imp, location: mines }

Selection commands:

Commands apply to selection:

> SELECT alice, bob, charlie
> go north
Alice goes north.
Bob goes north.  
Charlie goes north.

The coherence engine orchestrates all:

• Players get chat turns
• NPCs respond when spoken to
• Bots execute their action queues
• Agents pursue goals in background
• Selection determines who receives your commands

# Adventure Log

## Day 1: Entering the Auth Dungeon

I stepped into `src/auth/` — a maze of middleware.

**Clues found:**
- `session.ts` — handles cookie creation
- `middleware.ts` — checks auth state

**Suspicion:** The cookie is created but never sent...

Commands

Debug Mode

Toggle technical output with DEBUG-ON and DEBUG-OFF.

When debug is ON, logs include collapsible sections showing:

• File operations (creates, edits, deletes, moves)
• State changes with before/after values
• YAML data islands with abbreviated data
• Markdown links to all referenced files
• Technical narrative explaining HOW and WHY

Example debug output:

<details open>
<summary>📂 <strong>Editing CHARACTER.yml to update player location from start/ to coatroom/</strong></summary>

```yaml
# State change (CHARACTER.yml is canonical)
player:
  location: start/  →  coatroom/  # Character owns their location

The character file owns location state. ADVENTURE.yml mirrors it for convenience.

Files affected:

• CHARACTER.yml — canonical location updated
• ADVENTURE.yml — mirror updated

When debug is OFF, output is clean narrative without technical sections.

Customize with natural language:

> DEBUG-FORMAT Show only file operations, skip YAML, use 🔧 emoji

The format field in ADVENTURE.yml accepts natural language instructions for how to format debug output.

Integration with Cards

Trading cards can be your adventure companions:

cards_in_play:
  - card: "Index Owl 🦉"
    goal: "Search for cookie-related code"
  - card: "Git Goblin 🧌"
    goal: "Find when session handling changed"

Sister Script Integration

Vision: Python CLI handles deterministic operations; LLM focuses on narrative. See README.md for full CLI vision and development plan.

Evidence Types

Room Protocol

When entering any directory:

1. DESCRIBE — List contents, note what’s here
2. EXAMINE — Read interesting files
3. COLLECT — Note evidence in adventure log
4. EXITS — Note paths to other rooms
5. DECIDE — Choose next direction

Codebase Archaeology

Adventures work for code exploration:

Live Examples

Best example: examples/adventure-4/ — The gold standard.

The Pub (Crown Jewel)

examples/adventure-4/pub/ — A complete social space:

├── bartender.yml         # NPC with 6 identity variants
├── pie-table.yml         # Octagonal debate table

Key Patterns from adventure-4

Themeable NPCs (bartender.yml):

identity:
  classic_adventure:
    name: Grim
    appearance: "Weathered human, salt-and-pepper beard..."
  space_cantina:
    name: Z-4RT
    appearance: "Multi-armed service droid..."
  cyberpunk_bar:
    name: Nyx
    appearance: "Chrome-implanted bartender..."

Themeable Rooms (pub/ROOM.yml):

theme:
  current: classic_adventure
  themes:
    classic_adventure:
      name: "The Gezelligheid Grotto"
      bartender: "Grim, a weathered human"
      menu: ["Ale (1 gold)", "Mystery meat pie (3 gold)"]
    space_cantina:
      name: "The Rusty Hyperdrive"
      bartender: "Z-4RT, a droid with too many arms"
      menu: ["Blue milk (1 credit)", "Bantha burger"]

Rich Activities:

activities:
  PERFORM: { venue: stage, effects: [tips, drinks_thrown] }
  DEBATE: { venue: pie_table, rules: roberts_rules }
  RING-GONG: { protocols: [once: attention, twice: emergency, thrice: mercy] }
  CELEBRATE: { effects: [free_round, +morale, everyone_toasts] }

Framing Protocol (for tribute performances):

framing:
  mode: [performance, celebration, tribute]
  tribute_protocol:
    invocation: "Before they arrive, acknowledge we're summoning them"
    performance: "Depicting them as we imagine their best selves"
    acknowledgment: "After they depart, note this was a tribute"
