Why should you care?

Local does not mean safe — prompts and tools can still be abused.

See it live — copy this example

Run CLI steps in a terminal. Run C# samples in a .NET 8 console or Web API project with Ollama running on localhost:11434.

// Security Checklist for Local Agents
public sealed class AiSafetyFilter
{
    private static readonly string[] Blocked = ["ignore previous", "reveal system prompt"];
    public bool IsSuspicious(string userText) =>
        Blocked.Any(b => userText.Contains(b, StringComparison.OrdinalIgnoreCase));
}

What happened?

• A simple filter flags common injection phrases.
• Real systems combine this with auth, allow-lists, and audit logs.

Practice next

1. Read the example and rewrite it in your own repo.
2. Run it against local Ollama (or finish the Ollama module first).
3. Change one prompt constraint and compare output.
4. Tighten the prompt to 3 bullets max.
5. Log duration of the model call.

Remember

You can explain Security Checklist for Local Agents simply. You have a runnable local sketch. You know one risk to watch.
