Data Flow

"Rooms are nodes. Exits are edges. Thrown objects are messages."

MOOLLM's approach to building processing pipelines using rooms and objects. The filesystem IS the data flow network.

The Pattern

• Rooms are processing stages (nodes)
• Exits connect stages (edges)
• Objects flow through as messages
• THROW sends objects through exits
• INBOX receives incoming objects
• OUTBOX stages outgoing objects

Commands

Room Structure

Copystage/
├── ROOM.yml       # Config and processor definition
├── inbox/         # Incoming queue (FIFO)
├── outbox/        # Staged for batch throwing
└── door-next/     # Exit to next stage

Processor Types

Script (Deterministic)

Copyprocessor:
  type: script
  command: "python parse.py ${input}"

LLM (Semantic)

Copyprocessor:
  type: llm
  prompt: |
    Analyze this document:
    - Extract key entities
    - Summarize in 3 sentences

Hybrid

Copyprocessor:
  type: hybrid
  pre_process: "extract.py ${input}"
  llm_prompt: "Analyze extracted data"
  post_process: "format.py ${output}"

Mix and match. LLM for reasoning, scripts for transformation.

Example Pipeline

Copyuploads/              # Raw files land here
├── inbox/
│   ├── doc-001.pdf
│   └── doc-002.pdf
└── door-parser/

parser/               # Extract text
├── script: parse.py
└── door-analyzer/

analyzer/             # LLM analyzes
├── prompt: "Summarize..."
├── door-output/
└── door-errors/

output/               # Final results
└── inbox/
    ├── doc-001-summary.yml
    └── doc-002-summary.yml

Processing Loop

Copy> ENTER parser
Inbox: 2 items waiting.

> NEXT
Processing doc-001.pdf...
Text extracted.

> STAGE doc-001.txt door-analyzer
Staged.

> FLUSH
Throwing 2 items through door-analyzer...

Fan-Out (one-to-many)

Copyrouting_rules:
  - if: "priority == 'high'"
    throw_to: door-fast-track
  - if: "type == 'archive'"
    throw_to: door-archive
  - default: door-standard
