Workflows

Multi-step agent processes in the blueprint/ module.

---

Basic Workflow

from openstackai import Agent
from openstackai.blueprint import Workflow, Step

# Create specialized agents
researcher = Agent(name="Researcher", instructions="Find information on topics.")
writer = Agent(name="Writer", instructions="Write clear, engaging content.")
editor = Agent(name="Editor", instructions="Review and improve writing.")

# Build workflow
workflow = (Workflow("ContentPipeline")
    .add_step(Step("research", researcher))
    .add_step(Step("write", writer))
    .add_step(Step("edit", editor))
    .build())

# Run
result = await workflow.run("Create an article about AI trends")
print(result.final_output)

---

Step Types

Type	Description	Use Case
AGENT	Execute an agent	Main processing
SKILL	Call a specific skill	Tool invocation
FUNCTION	Run Python function	Custom logic
CONDITION	Conditional branching	Decision points
PARALLEL	Concurrent execution	Speed optimization
LOOP	Repeated execution	Iteration

---

Conditional Steps

from openstackai.blueprint import Workflow, Step, Condition

def needs_review(context):
    return context.get("complexity") == "high"

workflow = (Workflow("ReviewPipeline")
    .add_step(Step("analyze", analyzer))
    .add_step(Step("review", reviewer, condition=Condition(needs_review)))
    .add_step(Step("finalize", finalizer))
    .build())

---

Parallel Execution

from openstackai.blueprint import Workflow, ParallelStep

# Run multiple agents concurrently
workflow = (Workflow("ParallelResearch")
    .add_step(ParallelStep("research", [
        ("tech", tech_researcher),
        ("market", market_researcher),
        ("competitor", competitor_researcher),
    ]))
    .add_step(Step("synthesize", synthesizer))
    .build())

---

Workflow Context

Data flows through the workflow via context:

from openstackai.blueprint import WorkflowContext

# Initial context
context = WorkflowContext(
    input="Research topic",
    variables={"audience": "technical"}
)

result = await workflow.run(context)

# Access step outputs
print(result.steps["research"].output)
print(result.steps["write"].output)

---

Error Handling

workflow = (Workflow("SafePipeline")
    .add_step(Step("process", processor, 
        on_error="skip",      # skip, retry, fail
        retry_count=3,
        retry_delay=1.0
    ))
    .build())

Real-World Example: Content Creation

from openstackai import Agent
from openstackai.blueprint import Workflow, Step, ParallelStep

# Specialized team
topic_researcher = Agent(
    name="TopicResearcher",
    instructions="Research topics deeply and provide key facts."
)

seo_specialist = Agent(
    name="SEOSpecialist", 
    instructions="Identify keywords and SEO opportunities."
)

content_writer = Agent(
    name="ContentWriter",
    instructions="Write engaging blog posts with SEO optimization."
)

editor = Agent(
    name="Editor",
    instructions="Polish content for grammar, clarity, and flow."
)

# Content factory workflow
content_factory = (Workflow("ContentFactory")
    # Parallel research
    .add_step(ParallelStep("research", [
        ("topic", topic_researcher),
        ("seo", seo_specialist),
    ]))
    # Sequential writing and editing
    .add_step(Step("write", content_writer))
    .add_step(Step("edit", editor))
    .build())

# Generate content
result = await content_factory.run("AI in Healthcare: 2024 Trends")
print(result.final_output)

---

Workflow Persistence

Save and resume workflows:

# Save checkpoint
checkpoint = workflow.save_checkpoint()

# Resume later
workflow.restore_checkpoint(checkpoint)
result = await workflow.resume()

---

Combining with Patterns

Workflows can use orchestration patterns:

from openstackai.blueprint import ChainPattern, RouterPattern

# Chain pattern within workflow
chain = ChainPattern()
chain.add("analyze", analyzer)
chain.add("recommend", recommender)

workflow = (Workflow("Analysis")
    .add_step(Step("chain", chain))
    .build())
