Demo Skill

Demonstrates UltraRAG-style execution tracing with native workflows + YAML pipelines.

Tools

hello

Simple demo command for testing hot reload.

Parameters:

• name (string, optional): Name to greet (default: "Guest")

echo

Echo back the input message.

Parameters:

• message (string, optional): Message to echo (default: "Hello!")

test_yaml_pipeline

Test YAML pipeline compilation and execution with omni.tracer.

Parameters:

• pipeline_type (string, optional): Type of pipeline to test.

• "simple" : Sequential pipeline (analyze → draft → finalize)

• "loop" : Pipeline with iteration loop (analyze → evaluate → reflect)

• "branch" : Pipeline with conditional branching

• "rag" : Full RAG pipeline with retrieval

run_graphflow

Execute packaged graphflow runtime with trace output and quality gates.

Parameters:

• scenario (string, optional): Scenario name ("simple" or "complex" )

• quality_threshold (string, optional): Draft/finalize quality threshold

• quality_gate_novelty_threshold (string, optional): Gate novelty threshold

• quality_gate_coverage_threshold (string, optional): Gate coverage threshold

• quality_gate_min_evidence_count (string, optional): Minimum evidence count

• quality_gate_require_tradeoff (string, optional): Require trade-off in output

• quality_gate_max_fail_streak (string, optional): Max gate-fail streak before force-draft

list_pipeline_examples

List available YAML pipeline test examples.

Returns:

• Available pipeline types and their descriptions

• Usage instructions

Pipeline Examples

The demo skill includes YAML pipeline files in pipelines/ directory:

File Description Features

simple.yaml

Sequential pipeline analyze → draft → finalize

loop.yaml

Iterative reflection quality evaluation + loop

branch.yaml

Conditional routing router-based branching

rag.yaml

Full RAG retrieval + generation + evaluation

YAML Pipeline Structure

servers: generator: builtin

parameters: topic: "$topic"

pipeline:

• generator.analyze
• generator.draft
• generator.finalize

runtime: checkpointer: kind: memory tracer: callback_dispatch_mode: inline

UltraRAG Features

This demo showcases:

• YAML pipelines - Declarative workflow definitions

• Loop control - Iterative reflection with max_iterations

• Conditional branching - Router-based routing

• Memory tracking - Variables saved with history

• Rich output - Colored step-by-step tracing
