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
