description: Define and execute AI agent workflows using CSV-based declarative definitions
|
||||
with configurable branching logic
|
||||
inputs:
|
||||
- 'CSV workflow files defining agent graphs with columns: graph_name, node_name, agent_type,
|
||||
next_node, on_failure, prompt, input_fields, output_field'
|
||||
- LLM provider configuration (OpenAI, Anthropic, Google) in agentmap_config.yaml
|
||||
- Storage backend configuration in agentmap_config_storage.yaml
|
||||
steps:
|
||||
- Define workflow graph in CSV with nodes representing agent steps and their connections
|
||||
(next_node, on_failure)
|
||||
- Configure BranchingAgent with customizable success/failure values and fallback fields
|
||||
in the context dictionary
|
||||
- Initialize the agent runtime with ensure_initialized() and configure execution tracking
|
||||
and state adapter services
|
||||
- Execute the workflow using agentmap run with appropriate inputs and monitor the
|
||||
execution trace
|
||||
outputs:
|
||||
- Executed workflow with results stored in the specified output_field
|
||||
- Detailed execution trace showing success/failure decisions at each branching point
|

# branching-agent-pattern
|
||||
|
||||
Define and execute AI agent workflows using CSV-based declarative definitions with configurable branching logic
|
||||
|
||||
## Setup
|
||||
|
||||
**Dependencies:**
|
||||
|
||||
```text
|
||||
pip install langgraph>=1.0.0 langchain-core>=0.3.0 pyyaml>=6.0.0 fastapi>=0.111.0 uvicorn>=0.34.3
|
||||
```
|
||||
|
||||
**Setup steps:**
|
||||
|
||||
1. Install AgentMap: pip install agentmap[all]
|
||||
1. Configure llm providers in agentmap_config.yaml (OpenAI, Anthropic, Google models)
|
||||
1. Create CSV workflow files with graph definitions
|
||||
1. Initialize runtime with ensure_initialized()
|
||||
1. Run workflow with agentmap run <csv_file> --pretty
|
||||
|
||||
## Key Files
|
||||
|
||||
- `agentmap_config.yaml - Main configuration with LLM and storage settings`
|
||||
- `agentmap_config_storage.yaml - Storage backend configuration`
|
||||
- `hello_world.csv - Sample workflow demonstrating basic agent chain`
|
||||
- `examples/host_integration/custom_agents.py - Custom agent implementations with host service integration`
|
||||
|
||||
## Steps
|
||||
|
||||
1. Define workflow graph in CSV with nodes representing agent steps and their connections (next_node, on_failure)
|
||||
2. Configure BranchingAgent with customizable success/failure values and fallback fields in the context dictionary
|
||||
3. Initialize the agent runtime with ensure_initialized() and configure execution tracking and state adapter services
|
||||
4. Execute the workflow using agentmap run with appropriate inputs and monitor the execution trace
|
||||
|
||||
## Implementation Details
|
||||
|
||||
```python
|
||||
CSV format: graph_name,node_name,agent_type,next_node,on_failure,prompt,input_fields,output_field
|
||||
```
|
||||
|
||||
```python
|
||||
BranchingAgent context example: {'input_fields': ['success'], 'output_field': 'result', 'success_values': ['PASSED', 'COMPLETED']}
|
||||
```
|
||||
|
||||
```python
|
||||
Execution command: agentmap run hello_world.csv --pretty
|
||||
```
|
||||
|
||||
## Inputs
|
||||
|
||||
- CSV workflow files defining agent graphs with columns: graph_name, node_name, agent_type, next_node, on_failure, prompt, input_fields, output_field
|
||||
- LLM provider configuration (OpenAI, Anthropic, Google) in agentmap_config.yaml
|
||||
- Storage backend configuration in agentmap_config_storage.yaml
|
||||
|
||||
## Outputs
|
||||
|
||||
- Executed workflow with results stored in the specified output_field
|
||||
- Detailed execution trace showing success/failure decisions at each branching point
|
||||
- Updated workflow state persisted in the configured storage backend
|
||||
|
||||
## Failure Modes
|
||||
|
||||
- Invalid CSV format causing parsing errors during workflow loading
|
||||
- Missing or misconfigured LLM provider settings leading to execution failures
|
||||
- Storage backend unavailable or misconfigured preventing workflow persistence
|
||||
- Agent execution timeout due to long-running operations or infinite loops

# graph-based-node-orchestration
|
||||
|
||||
Build a typed node graph that processes data through a sequence of operations and produces a final result
|
||||
|
||||
## Setup
|
||||
|
||||
**Dependencies:**
|
||||
|
||||
```text
|
||||
pip install blacknode >= 0.3.0 Python >= 3.11 NVIDIA NIM API key (optional but recommended) Anthropic, OpenAI, or other LLM models
|
||||
```
|
||||
|
||||
**Setup steps:**
|
||||
|
||||
1. Clone the repository and install dependencies: pip install -e .
|
||||
1. Set NVIDIA_API_KEY or other required API keys in .env
|
||||
1. Run the example script: python examples/hello_agent.py
|
||||
1. For production, configure hardware pairing and deploy via the blacknode CLI
|
||||
|
||||
## Key Files
|
||||
|
||||
- `examples/converted_nvidia_nim.py - Full graph with Model, Text, LLMAgent, Output nodes`
|
||||
- `examples/hello_agent.py - Minimal agent example connecting Literal → LLMAgent → Print`
|
||||
- `blacknode/core - Graph and node implementation (internal)`
|
||||
|
||||
## Steps
|
||||
|
||||
1. Import required modules (blacknode as bn, NIM_MODEL) and ensure API keys are available via require_nim_api_key()
|
||||
2. Create a bn.Graph() instance to hold all nodes and their connections
|
||||
3. Define individual nodes with specific input/output parameters (e.g., Text node with 'value' input, LLMAgent node with model parameter, Output node with 'value' output)
|
||||
4. Connect nodes together using edge definitions (from_port -> to_port) to establish data flow
|
||||
5. Execute the graph using g.cook() to run the pipeline and process data through the node chain
|
||||
6. Extract the final result from the output node to complete the workflow
|
||||
|
||||
## Implementation Details
|
||||
|
||||
```python
|
||||
g = bn.Graph()
|
||||
```
|
||||
|
||||
```python
|
||||
model = g.node('Model', **{'value': 'nim:meta/llama-3.1-8b-instruct'})
|
||||
```
|
||||
|
||||
```python
|
||||
agent = g.node('LLMAgent', **{model})
|
||||
```
|
||||
|
||||
```python
|
||||
result = g.cook(output, 'value')
|
||||
```
|
||||
|
||||
## Inputs
|
||||
|
||||
- NIM_MODEL constant (e.g., 'nim:meta/llama-3.1-8b-instruct') for the LLM model
|
||||
- blacknode package with Graph, Node, and cook functionality
|
||||
- Python script defining node types with inputs/outputs and connecting them via edges
|
||||
|
||||
## Outputs
|
||||
|
||||
- A fully constructed graph with typed nodes and defined connections
|
||||
- Executed result (e.g., processed text, summary, or other output) from the final node
|
||||
- A reusable pattern that can be adapted to different models, hardware, or task types
|
||||
|
||||
## Failure Modes
|
||||
|
||||
- Missing or invalid API key (NIM_API_KEY, OPENAI_API_KEY) causing require_nim_api_key() to fail
|
||||
- Type mismatch in node connections (e.g., expecting 'value' but receiving 'text') breaking the data flow
|
||||
- Model not available or unreachable (NIM_MODEL not found) causing the LLMAgent node to fail
|
||||
- Graph execution error due to incorrect edge configuration or circular dependencies
|
||||
- Resource exhaustion (e.g., GPU memory) when processing large inputs in the pipeline
