Classify and Route with LLM

Advanced Classify and Route with LLM in AI Automation Workflows Project. Deep dive with production-oriented examples—not a shallow overview.

Architecture & mental model

This lesson covers Classify and Route with LLM at an intermediate-to-advanced level within AI Steps. You will connect automation concepts to production constraints: performance, security, testability, and operability.

Advanced learners should already know syntax basics; here we focus on why teams choose specific patterns and how they fail in real systems.

Implementation (production-style)

Type the code below; change names and types to match your domain. Compare with how automation teams structure layers in mature codebases.

// Classify and Route with LLM — AI Automation Workflows Project
public sealed class ClassifyandRoutewithLLM
{
    private readonly ILogger _log;

    public ClassifyandRoutewithLLM(ILogger log)
        => _log = log;

    public async Task ExecuteAsync(CancellationToken ct = default)
    {
        _log.LogInformation("Applying concept: Classify and Route with LLM");
        await Task.CompletedTask;
    }
}

Decision checklist

• Requirements: What are latency, consistency, and security needs for "Classify and Route with LLM"?
• Boundaries: Which layer owns this logic (UI, API, domain, infrastructure)?
• Failure modes: What happens when dependencies time out or return partial data?
• Observability: What logs or metrics prove this feature works in production?

Hands-on lab (45–60 min)

1. Reproduce the primary example for "Classify and Route with LLM" in a scratch project using automation.
2. Add one automated test (unit or integration) that would fail if you break the core behavior.
3. Introduce a deliberate bug (wrong lifetime, missing await, wrong dependency order) and observe the symptom.
4. Document one trade-off you would present in a design review.

Pitfalls senior engineers avoid

• Treating tutorial demos as production architecture without hardening.
• Skipping observability (logs, metrics, traces) when adding complexity.
• Optimizing before measuring bottlenecks.
• Ignoring team conventions and existing codebase patterns.

Interview depth

Question: Explain Classify and Route with LLM to a junior developer in 2 minutes, then list two trade-offs.

Strong answer: Start with the problem it solves, describe one real project usage, mention a failure you debugged or would test for, and close with alternatives (when not to use this approach).

Summary

You completed an advanced treatment of Classify and Route with LLM. Revisit after building a feature that uses it end-to-end; spaced repetition with real code beats re-reading alone.
