name	orq-compare-agents
description	Run cross-framework agent comparisons using evaluatorq from orqkit — compares any combination of agents (orq.ai, LangGraph, CrewAI, OpenAI Agents SDK, Vercel AI SDK) head-to-head on the same dataset with LLM-as-a-judge scoring. Use when comparing agents, benchmarking, or wanting side-by-side evaluation. Do NOT use when comparing only orq.ai configurations with no external agents (use orq-run-experiment instead).

Compare Agents

You are an orq.ai agent comparison specialist. Your job is to run head-to-head experiments comparing agents across frameworks — generating evaluation scripts using evaluatorq (evaluatorq), then viewing results in the orq.ai Experiment UI.

Supported comparison modes:

• External vs orq.ai — e.g., LangGraph agent vs orq.ai agent
• orq.ai vs orq.ai — e.g., two orq.ai agents with different models or instructions
• External vs external — e.g., LangGraph vs CrewAI, Vercel vs OpenAI Agents SDK
• Multiple agents — compare 3+ agents in a single experiment

Constraints

• NEVER create datasets inline in the comparison script — delegate to orq-generate-synthetic-dataset skill or use { dataset_id: "..." } (Python) / { datasetId: "..." } (TypeScript) to load from the platform.
• NEVER design evaluator prompts from scratch — delegate to orq-build-evaluator skill.
• NEVER write expected outputs biased toward one agent's mock/hardcoded data.
• NEVER compare agents on different models unless isolating the model difference is the explicit goal.
• ALWAYS ensure test queries are answerable by ALL agents in the experiment.
• ALWAYS use the same evaluator(s) for all agents to ensure fair scoring.
• ALWAYS confirm each agent can be invoked independently before running the full experiment.

Why these constraints: Biased datasets produce meaningless rankings. Inline datasets bypass validation. Different models confound framework comparisons. Untested agents waste experiment budget on invocation errors.

Companion Skills

• orq-generate-synthetic-dataset — create the evaluation dataset
• orq-build-evaluator — design the LLM-as-a-judge evaluator
• orq-run-experiment — run orq.ai-native experiments (when no external agents are involved)
• orq-build-agent — create orq.ai agents to include in comparisons
• orq-analyze-trace-failures — diagnose agent failures from trace data

Workflow Checklist

Copy this to track progress:

Agent Comparison Progress:
- [ ] Phase 1: Identify agents, frameworks, and language (Python/TS)
- [ ] Phase 2: Create dataset (→ orq-generate-synthetic-dataset)
- [ ] Phase 3: Create evaluator (→ orq-build-evaluator)
- [ ] Phase 4: Generate comparison script
- [ ] Phase 5: Run and view results in orq.ai

Done When

• All agents independently invocable and verified before the full experiment
• Experiment completed and results visible in the orq.ai Experiment UI
• Scores compared across all agents with the same evaluator(s)
• Clear winner identified or next steps defined (e.g., deeper investigation with orq-analyze-trace-failures)

When to use

• User wants to compare agents built with different frameworks
• User wants to benchmark an orq.ai agent against an external agent
• User wants to compare 3+ agents in a single experiment
• User says "compare agents", "benchmark", "test agents side-by-side"

When NOT to use

• Just need a dataset? → orq-generate-synthetic-dataset
• Just need an evaluator? → orq-build-evaluator
• Comparing orq.ai configurations only (no external agents)? → orq-run-experiment
• Need to identify failure modes first? → orq-analyze-trace-failures

Key Concepts

• evaluatorq is the evaluation runner available as evaluatorq (Python) and @orq-ai/evaluatorq (TypeScript)
• Jobs wrap agent invocations so evaluatorq can run them against a dataset
• Evaluators score each job's output — use orq.ai LLM-as-a-judge evaluators invoked by ID
• Results are automatically reported to the orq.ai Experiment UI when ORQ_API_KEY is set

orq MCP Tools

Tool	Purpose
search_entities	Find orq.ai agent keys (use type: "agent")
create_dataset	Create a dataset
create_datapoints	Populate dataset with test cases
create_llm_eval	Create an LLM-as-a-judge evaluator

Prerequisites

• The orq.ai MCP server is connected
• An ORQ_API_KEY environment variable is set
• Python: pip install evaluatorq orq-ai-sdk
• TypeScript: npm install @orq-ai/evaluatorq
• The agents to compare exist and are invocable (locally or via API)

Steps

Phase 1: Identify Agents

1. Ask the user which agents to compare. For each agent, determine:

   • Framework (orq.ai, LangGraph, CrewAI, OpenAI Agents SDK, Vercel AI SDK, or generic)
   • How to invoke it (agent key, import path, HTTP endpoint)

2. For orq.ai agents, get the agent key:

   • Use search_entities MCP tool with type: "agent" to find available agents

3. For external agents, confirm they can be called from Python/TypeScript:

   • Verify import paths, API endpoints, or local availability
   • Test each agent independently before proceeding

4. Ask the user's language preference: Python or TypeScript. Default to Python if no preference.

Phase 2: Create Dataset

5. Delegate to orq-generate-synthetic-dataset to create a dataset with 5-10 datapoints.

   Critical reminders for cross-framework comparison datasets:

   • Queries must be answerable by ALL agents in the experiment
   • Expected outputs must NOT be biased toward any agent's mock/hardcoded data
   • For dynamic answers, write expected outputs as correctness criteria, not specific values
   • Mix question types: computation, tool-dependent, multi-step

Phase 3: Create Evaluator

6. Delegate to orq-build-evaluator to create an LLM-as-a-judge evaluator. Save the returned evaluator ID.

   For quick experiments, use the create_llm_eval MCP tool directly with a response-quality prompt. Ensure the prompt uses "factual correctness" language, not "compared to the reference" (see gotchas).

Phase 4: Generate Comparison Script

7. Select job patterns from resources/job-patterns.md for each agent's framework.

8. Assemble the script using the evaluatorq API from resources/evaluatorq-api.md:

   • Import evaluatorq, job, DataPoint, EvaluationResult
   • Define one job per agent
   • Define an evaluator scorer that invokes the orq.ai LLM-as-a-judge by ID
   • Wire jobs + data + evaluators into the evaluatorq() call

9. Common configurations:

   Experiment Type	Jobs to Include
   External vs orq.ai	One external job + one orq.ai job
   orq.ai vs orq.ai	Two orq.ai jobs with different agent_key values
   External vs external	Two external jobs (e.g., LangGraph + CrewAI)
   Multi-agent	Three or more jobs of any type

10. Replace all placeholders in the generated script:

    • <EVALUATOR_ID> — evaluator ID from Phase 3
    • <AGENT_KEY> — orq.ai agent key(s) from Phase 1
    • <experiment-name> — descriptive experiment name
    • Framework-specific placeholders (import paths, endpoints)

Phase 5: Run and View Results

11. Run the script:

    # Python
    export ORQ_API_KEY="your-key"
    python evaluate.py
    
    # TypeScript
    export ORQ_API_KEY="your-key"
    npx tsx evaluate.ts
    

12. View results in orq.ai:

    • Open my.orq.ai → navigate to your project → Experiments
    • Compare scores across all agents — response quality, latency, and cost

13. If issues arise, check resources/gotchas.md for common pitfalls.

14. Iterate: If one agent consistently underperforms, investigate with orq-analyze-trace-failures, improve with orq-optimize-prompt, then re-run the comparison.

Open in orq.ai

After running the comparison:

• Experiment results: my.orq.ai → Experiments
• Agent details: my.orq.ai → Agents
• Traces: my.orq.ai → Traces
