In the rapidly evolving landscape of AI-driven software development,
**agentic workflows** represent a paradigm shift from traditional
automation. Rather than following rigid, prescriptive steps, agentic
systems employ autonomous AI agents that dynamically collaborate to
achieve complex objectives. This article presents a comprehensive
technical overview of an AI-powered agentic workflow system designed
specifically for project management automation.
The system transforms high-level product specifications into complete,
structured project plans—including user stories, feature definitions,
and engineering tasks—without human intervention. By leveraging Large
Language Models (LLMs) and intelligent agent orchestration, it
demonstrates how autonomous agents can handle sophisticated business
workflows that traditionally require multiple stakeholders.
## System Architecture
### Core Design Philosophy
The architecture follows a **multi-agent orchestration pattern** where
specialized agents collaborate through a coordinated workflow. Each
agent possesses domain-specific knowledge and capabilities, mirroring
real-world project management roles:
- **Product Manager Agent**: Defines user stories and personas
- **Program Manager Agent**: Groups stories into cohesive features
- **Development Engineer Agent**: Creates detailed engineering tasks
- **Action Planning Agent**: Decomposes high-level goals into logical sub-tasks
- **Routing Agent**: Intelligently distributes work to appropriate specialists
- **Evaluation Agent**: Ensures quality through iterative refinement

## Agent Library Implementation
### 1. Direct Prompt Agent
The foundation of the agent library, this class provides
straightforward LLM interaction:
```python
class DirectPromptAgent:
def __init__(self, openai_api_key):
self.openai_api_key = openai_api_key
def respond(self, prompt):
client = OpenAI(api_key=self.openai_api
response = client.chat.completions.create
model="gpt-3.5-turbo",
messages=[{"role": "user", "content": prompt}],
temperature=0
)
return response.choices[0].message.co
```
**Key Characteristics:**
- Zero-shot prompting
- No system context or memory
- Relies solely on LLM's pre-trained knowledge
- Best for simple, context-free queries
### 2. Augmented Prompt Agent
Introduces **persona-based responses** for role-specific outputs:
```python
class AugmentedPromptAgent:
def __init__(self, openai_api_key, persona):
self.persona = persona
self.openai_api_key = openai_api_key
def respond(self, input_text):
client = OpenAI(api_key=self.openai_api
response = client.chat.completions.create
model="gpt-3.5-turbo",
messages=[
{
"role": "system",
"content": f"You are {self.persona}. Forget all
previous context."
},
{"role": "user", "content": input_text}
],
temperature=0
)
return response.choices[0].message.co
```
**Use Cases:**
- Role-specific guidance (e.g., "technical writer," "security auditor")
- Consistent tone and perspective
- Domain-appropriate terminology
### 3. Knowledge-Augmented Prompt Agent
The workhorse of the system, this agent combines persona with
**explicit domain knowledge**:
```python
class KnowledgeAugmentedPromptAgent:
def __init__(self, openai_api_key, persona, knowledge):
self.persona = persona
self.knowledge = knowledge
self.openai_api_key = openai_api_key
def respond(self, input_text):
client = OpenAI(api_key=self.openai_api
system_prompt = (
f"You are {self.persona}. Use only the following knowledge: "
f"{self.knowledge}. Do not use your own knowledge."
)
response = client.chat.completions.create
model="gpt-3.5-turbo",
messages=[
{"role": "system", "content": system_prompt},
{"role": "user", "content": input_text}
],
temperature=0
)
return response.choices[0].message.co
```
**Example Application:**
```python
persona_product_manager = "You are a Product Manager responsible for
user stories."
knowledge = f"""
User stories follow the structure:
'As a [type of user], I want [action] so that [benefit].'
Product Specification: {product_spec}
"""
pm_agent = KnowledgeAugmentedPromptAgent(
persona_product_manager, knowledge)
```
**Advantages:**
- Enforces adherence to specific documentation
- Reduces hallucinations
- Maintains consistent outputs based on organizational knowledge
### 4. RAG Knowledge Prompt Agent
Implements **Retrieval-Augmented Generation (RAG)** for large knowledge bases:
**Key Features:**
- Text chunking with configurable overlap
- Vector embeddings using `text-embedding-3-large`
- Cosine similarity-based retrieval
- Dynamic context injection
**Technical Implementation:**
```python
def chunk_text(self, text):
"""Splits text into manageable chunks with overlap"""
chunks = []
start = 0
while start < len(text):
end = min(start + self.chunk_size, len(text))
chunks.append(text[start:end])
start = end - self.chunk_overlap
return chunks
def find_prompt_in_knowledge(self, prompt):
"""Retrieves most similar chunk and generates response"""
prompt_embedding = self.get_embedding(prompt)
df['similarity'] = df['embeddings'].apply(
lambda emb: self.calculate_similarity(prom
)
best_chunk = df.loc[df['similarity'].idxmax
# Generate response using best_chunk
```
**Use Cases:**
- Large documentation repositories
- Dynamic knowledge bases
- Efficient information retrieval
### 5. Evaluation Agent
Implements **iterative quality control** through agent collaboration:
```python
class EvaluationAgent:
def __init__(self, openai_api_key, persona, evaluation_criteria,
worker_agent, max_interactions):
self.evaluation_criteria = evaluation_criteria
self.worker_agent = worker_agent
self.max_interactions = max_interactions
def evaluate(self, initial_prompt):
for i in range(self.max_interactions):
# Step 1: Worker generates response
response = self.worker_agent.respond(prom
# Step 2: Evaluate response
evaluation = self._check_criteria(response)
# Step 3: Check if acceptable
if evaluation.lower().startswith(
break
# Step 4: Generate correction instructions
instructions = self._generate_corrections(eva
# Step 5: Refine prompt with feedback
prompt_to_evaluate = self._create_refinement_prompt
initial_prompt, response, instructions
)
return {"final_response": response, "iterations": i + 1}
```
**Quality Gates:**
- Automatic verification against defined criteria
- Iterative refinement loops
- Prevents suboptimal outputs from propagating downstream
**Example Evaluation Criteria:**
```python
evaluation_criteria = """
User stories must follow: 'As a [user type], I want [action] so that [benefit].'
Each story must:
1. Be concise and specific
2. Focus on user value
3. Be testable and actionable
"""
```
### 6. Routing Agent
Implements **semantic routing** using embedding-based similarity:
```python
class RoutingAgent:
def __init__(self, openai_api_key, agents):
self.agents = agents # List of {name, description, func}
self.openai_api_key = openai_api_key
def route(self, user_input):
input_embedding = self.get_embedding(user_input)
best_agent = None
best_score = -1
for agent in self.agents:
agent_embedding = self.get_embedding(agent['desc
similarity = cosine_similarity(input_embedd
if similarity > best_score:
best_score = similarity
best_agent = agent
return best_agent['func'](user_input)
```
**Routing Configuration:**
```python
routing_agents = [
{
"name": "Product Manager",
"description": "Defines personas and user stories based on
product specs",
"func": lambda x: product_manager_workflow(x)
},
{
"name": "Program Manager",
"description": "Groups user stories into cohesive product features",
"func": lambda x: program_manager_workflow(x)
},
{
"name": "Development Engineer",
"description": "Creates detailed engineering tasks with
acceptance criteria",
"func": lambda x: dev_engineer_workflow(x)
}
]
```
**Advantages:**
- Dynamic task distribution
- No hard-coded logic
- Extensible to new agent types
### 7. Action Planning Agent
Decomposes high-level goals into executable sub-tasks:
```python
class ActionPlanningAgent:
def __init__(self, openai_api_key, knowledge):
self.knowledge = knowledge
self.openai_api_key = openai_api_key
def extract_steps_from_prompt(self
system_prompt = f"""
You are an action planning agent. Extract the steps required
to complete the action. Return only steps from this knowledge:
{self.knowledge}
"""
response = client.chat.completions.create
model="gpt-3.5-turbo",
messages=[
{"role": "system", "content": system_prompt},
{"role": "user", "content": prompt}
]
)
# Parse and clean response into list of steps
return self._parse_steps(response.cho
```
**Workflow Integration:**
```python
knowledge_action_planning = """
1. Define user stories from product specifications
2. Group related stories into feature sets
3. Create engineering tasks for each story
"""
action_agent = ActionPlanningAgent(api_key, knowledge_action_planning)
steps = action_agent.extract_steps_fro
for step in steps:
result = routing_agent.route(step)
completed_steps.append(result)
```
## Complete Workflow Implementation

"""
steps = action_planning_agent.extract_
results = []
for step in steps:
print(f"Processing: {step}")
result = routing_agent.route(step)
results.append(result)
print(f"Completed: {result[:200]}...\n")
