# Agent Operations: Build, Evaluate, and Monitor AI Agents

This skill covers the agent lifecycle beyond basic tracing: architecture patterns, evaluation, metrics, and production monitoring. All examples use Opik for observability — for SDK details (tracing, integrations, span types), load the `opik` skill.

## The Agent Lifecycle

1. **Instrument** — Add Opik tracing to make your agent's behavior visible (see `opik` skill)
2. **Evaluate** — Measure performance with datasets, metrics, and experiments
3. **Monitor** — Track quality, cost, and reliability in production
4. **Optimize** — Improve based on data from evaluation and production traces

## Agent Architecture Patterns

Trace every component of your agent with appropriate span types:

```python
import opik

@opik.track(name="research_agent")
def agent(query: str) -> str:
    plan = plan_action(query)        # general span
    results = execute_tool(plan)     # tool span
    return generate_response(results) # llm span

@opik.track(type="tool")
def execute_tool(action: dict) -> str:
    return search_web(action["query"])

@opik.track(type="llm")
def generate_response(context: str) -> str:
    return llm_call(context)
```

### What to Trace

| Component | Span Type | Key Data |
|-----------|-----------|----------|
| Planning | `general` | Reasoning steps, decisions |
| Tool calls | `tool` | Tool name, parameters, results |
| LLM calls | `llm` | Prompt, response, tokens |
| Retrieval | `tool` | Query, documents |
| Validation | `guardrail` | Check results, pass/fail |

## Evaluation

Evaluate agents at multiple levels — end-to-end and per-component:

```python
from opik.evaluation import evaluate
from opik.evaluation.metrics import AnswerRelevance, Hallucination, AgentTaskCompletion

results = evaluate(
    experiment_name="agent-v2",
    dataset=dataset,
    task=lambda item: {"output": agent(item["input"])},
    scoring_metrics=[
        AnswerRelevance(),
        Hallucination(),
        AgentTaskCompletion(),
    ]
)
```

### Built-in Agent Metrics

| Metric | What It Measures |
|--------|-----------------|
| `AgentTaskCompletion` | Did the agent fulfill its task? |
| `AgentToolCorrectness` | Were tools used correctly? |
| `TrajectoryAccuracy` | Did actions match expected sequence? |
| `AnswerRelevance` | Does the answer address the question? |
| `Hallucination` | Are there unsupported claims? |

### 41 Total Built-in Metrics

Heuristic (Equals, Contains, BLEU, ROUGE, BERTScore, IsJson, etc.), LLM-as-Judge (AnswerRelevance, Hallucination, Usefulness, GEval, etc.), RAG (ContextPrecision, ContextRecall, Faithfulness), and conversation metrics. See `references/evaluation.md` for the full list.

## Production Monitoring

- **Dashboards** — Visualize quality, cost, latency, and error trends
- **Online evaluation** — Automatically score production traces with LLM-as-Judge
- **Alerts** — Get notified when metrics deviate (quality drops, cost spikes, error rates)
- **Guardrails** — PII detection, topic validation, custom safety checks
- **Opik Assist** — AI-powered root cause analysis for failed traces

## Common Anti-Patterns

| Category | Anti-Pattern |
|----------|-------------|
| Reliability | Unbounded loops, retry storms, silent failures |
| Security | Prompt injection, privilege escalation, data leakage |
| Observability | Late tracing (missing input), orphaned spans |
| Tools | Tool loops, hallucinated tools, parameter errors |
