Agent Pipeline Chaining SOP

Overview

This skill implements agent pipeline chaining where outputs from one agent become inputs to the next, supporting both sequential and parallel execution patterns with streaming data flows.

Agents & Responsibilities

task-orchestrator

Role: Pipeline coordination and orchestration Responsibilities:

• Design pipeline architecture
• Connect agent stages
• Monitor data flow
• Handle pipeline errors

memory-coordinator

Role: Data flow and state management Responsibilities:

• Store intermediate results
• Coordinate data passing
• Manage pipeline state
• Ensure data consistency

Phase 1: Design Pipeline

Objective

Design pipeline architecture with stages, data flows, and execution strategy.

Scripts

# Design pipeline architecture
npx claude-flow@alpha pipeline design \
  --stages "research,analyze,code,test,review" \
  --flow sequential \
  --output pipeline-design.json

# Define data flow
npx claude-flow@alpha pipeline dataflow \
  --design pipeline-design.json \
  --output dataflow-spec.json

# Visualize pipeline
npx claude-flow@alpha pipeline visualize \
  --design pipeline-design.json \
  --output pipeline-diagram.png

# Store design in memory
npx claude-flow@alpha memory store \
  --key "pipeline/design" \
  --file pipeline-design.json

Pipeline Patterns

Sequential Pipeline:

Agent1 → Agent2 → Agent3 → Agent4

Parallel Pipeline:

       ┌─ Agent2 ─┐
Agent1 ├─ Agent3 ─┤ Agent5
       └─ Agent4 ─┘

Hybrid Pipeline:

Agent1 → ┬─ Agent2 ─┐
         └─ Agent3 ─┴─ Agent4 → Agent5

Phase 2: Connect Agents

Objective

Connect agents with proper data flow channels and state management.

Scripts

# Initialize pipeline
npx claude-flow@alpha pipeline init \
  --design pipeline-design.json

# Spawn pipeline agents
npx claude-flow@alpha agent spawn --type researcher --pipeline-stage 1
npx claude-flow@alpha agent spawn --type analyst --pipeline-stage 2
npx claude-flow@alpha agent spawn --type coder --pipeline-stage 3
npx claude-flow@alpha agent spawn --type tester --pipeline-stage 4

# Connect pipeline stages
npx claude-flow@alpha pipeline connect \
  --from-stage 1 --to-stage 2 \
  --data-channel "memory"

npx claude-flow@alpha pipeline connect \
  --from-stage 2 --to-stage 3 \
  --data-channel "stream"

# Verify connections
npx claude-flow@alpha pipeline status --show-connections

Data Flow Mechanisms

Memory-Based:

# Agent 1 stores output
npx claude-flow@alpha memory store \
  --key "pipeline/stage-1/output" \
  --value "research findings..."

# Agent 2 retrieves input
npx claude-flow@alpha memory retrieve \
  --key "pipeline/stage-1/output"

Stream-Based:

# Agent 1 streams output
npx claude-flow@alpha stream write \
  --channel "stage-1-to-2" \
  --data "streaming data..."

# Agent 2 consumes stream
npx claude-flow@alpha stream read \
  --channel "stage-1-to-2"

Phase 3: Execute Pipeline

Objective

Execute pipeline with proper sequencing and data flow.

Scripts

# Execute sequential pipeline
npx claude-flow@alpha pipeline execute \
  --design pipeline-design.json \
  --input initial-data.json \
  --strategy sequential

# Execute parallel pipeline
npx claude-flow@alpha pipeline execute \
  --design pipeline-design.json \
  --input initial-data.json \
  --strategy parallel \
  --max-parallelism 3

# Monitor execution
npx claude-flow@alpha pipeline monitor --interval 5

# Track stage progress
npx claude-flow@alpha pipeline stages --show-progress

Execution Strategies

Sequential:

• Stages execute one after another
• Output of stage N is input to stage N+1
• Simple error handling
• Predictable execution time

Parallel:

• Independent stages execute simultaneously
• Outputs merged at synchronization points
• Complex error handling
• Faster overall execution

Adaptive:

• Dynamically switches between sequential and parallel
• Based on stage dependencies and resource availability
• Optimizes for throughput

Phase 4: Monitor Streaming

Objective

Monitor data flow and pipeline execution in real-time.

Scripts

# Monitor data flow
npx claude-flow@alpha stream monitor \
  --all-channels \
  --interval 2 \
  --output stream-metrics.json

# Track stage throughput
npx claude-flow@alpha pipeline metrics \
  --metric throughput \
  --per-stage

# Monitor backpressure
npx claude-flow@alpha stream backpressure --detect

# Generate flow report
npx claude-flow@alpha pipeline report \
  --include-timing \
  --include-throughput \
  --output pipeline-report.md

Key Metrics

• Stage Throughput: Items processed per minute per stage
• Pipeline Latency: End-to-end processing time
• Backpressure: Queue buildup at stage boundaries
• Error Rate: Failures per stage
• Resource Utilization: CPU/memory per agent

Phase 5: Validate Results

Objective

Validate pipeline outputs and ensure data integrity.

Scripts

# Collect pipeline results
npx claude-flow@alpha pipeline results \
  --output pipeline-results.json

# Validate data integrity
npx claude-flow@alpha pipeline validate \
  --results pipeline-results.json \
  --schema validation-schema.json

# Compare with expected output
npx claude-flow@alpha pipeline compare \
  --actual pipeline-results.json \
  --expected expected-output.json

# Generate validation report
npx claude-flow@alpha pipeline report \
  --type validation \
  --output validation-report.md

Success Criteria

• Pipeline design complete
• All stages connected
• Data flow functional
• Outputs validated
• Performance acceptable

Performance Targets

• Stage latency: <30 seconds average
• Pipeline throughput: ≥10 items/minute
• Error rate: <2%
• Data integrity: 100%

Best Practices

1. Clear Stage Boundaries: Each stage has single responsibility
2. Data Validation: Validate outputs before passing to next stage
3. Error Handling: Implement retry and fallback mechanisms
4. Backpressure Management: Prevent queue overflow
5. Monitoring: Track metrics continuously
6. State Management: Use memory coordination for state
7. Testing: Test each stage independently
8. Documentation: Document data schemas and flows

Common Issues & Solutions

Issue: Pipeline Stalls

Symptoms: Stages stop processing Solution: Check for backpressure, increase buffer sizes

Issue: Data Loss

Symptoms: Missing data in outputs Solution: Implement acknowledgment mechanism, use reliable channels

Issue: High Latency

Symptoms: Slow end-to-end processing Solution: Identify bottleneck stage, add parallelism

Integration Points

• swarm-orchestration: For complex multi-pipeline orchestration
• advanced-swarm: For optimized agent coordination
• performance-analysis: For bottleneck detection
