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 (orqkit), 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 generate-synthetic-dataset skill or use { dataset_id: "..." } (Python) / { datasetId: "..." } (TypeScript) to load from the platform.
NEVER design evaluator prompts from scratch — delegate to 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

generate-synthetic-dataset — create the evaluation dataset
build-evaluator — design the LLM-as-a-judge evaluator
run-experiment — run orq.ai-native experiments (when no external agents are involved)
build-agent — create orq.ai agents to include in comparisons
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 (→ generate-synthetic-dataset)
- [ ] Phase 3: Create evaluator (→ 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 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? → generate-synthetic-dataset
Just need an evaluator? → build-evaluator
Comparing orq.ai configurations only (no external agents)? → run-experiment
Need to identify failure modes first? → analyze-trace-failures

Key Concepts

evaluatorq is the evaluation runner from orqkit — 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

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)
For orq.ai agents, get the agent key:
- Use search_entities MCP tool with type: "agent" to find available agents
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
Ask the user's language preference: Python or TypeScript. Default to Python if no preference.

Phase 2: Create Dataset

Delegate to 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

Delegate to 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

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

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

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

Run the script:

# Python
export ORQ_API_KEY="your-key"
python evaluate.py

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

View results in orq.ai:
- Open my.orq.ai → navigate to your project → Experiments
- Compare scores across all agents — response quality, latency, and cost
If issues arise, check resources/gotchas.md for common pitfalls.
Iterate: If one agent consistently underperforms, investigate with analyze-trace-failures, improve with 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

When this skill conflicts with live API responses or docs.orq.ai, trust the API.
