+# graph-based-node-workflow
+
+Create and execute typed node graphs for AI/robotics workflows by defining nodes with inputs/outputs and connecting them with edges, then cooking the graph to run the workflow.
+
+## Setup
+
+**Dependencies:**
+
+```text
+pip install blacknode (core Python package) anthropic, openai, docker, petgraph (dependencies) Rust extensions in blacknode-core, blacknode-runtime (optional)
+```
+
+**Setup steps:**
+
+1. Install blacknode with Python 3.11+ and required dependencies
+1. Clone repository and navigate to project directory
+1. Run examples/converted_text_pipeline.py to see basic graph execution
+1. Modify node definitions and edges to create custom workflows
+
+## Key Files
+
+- `examples/converted_text_pipeline.py - basic pipeline pattern`
+- `examples/hello_agent.py - LLM agent workflow pattern`
+- `examples/research_pipeline.py - multi-node research workflow`
+- `blacknode.py - main CLI entry point`
+
+## Steps
+
+1. Step 1: Initialize a bn.Graph() instance to serve as the workflow container
+2. Step 2: Define individual nodes with their required inputs and outputs (e.g., Literal for data, LLMAgent for inference, Concat for combining, Output for final results)
+3. Step 3: Create edges connecting nodes by specifying source from_port and destination to_port for each data flow
+4. Step 4: Execute the graph by calling g.cook() to process the defined workflow and produce results
+
+## Implementation Details
+
+```python
+g = bn.Graph()
+```
+
+```python
+g._edges = [{"from": "model", "from_port": "value", "to": "agent", "to_port": "model"}]
+```
+
+```python
+result = g.cook(output, "value")
+```
+
+## Inputs
+
+- bn.Graph() - the graph container for the workflow
+- Node definitions (Literal, Text, LLMAgent, Concat, Output, etc.) with specified inputs and outputs
+- Edge connections mapping from_port to to_port between nodes
+
+## Outputs
+
+- Executed workflow results stored in the graph's output nodes
+- Cooked graph ready for inspection, replay, or deployment
+- Potential error states if node dependencies are missing or ports don't match
+
+## Failure Modes
+
+- Missing node dependencies causing undefined variable errors
+- Port mismatch in edge connections leading to no data flow
+- Incomplete graph definition causing cook() to fail
+- Model API key missing or invalid for LLMAgent nodes
