Content Safety
~2 min read
Concept & How It Works
Why Does It Exist?
One harmful response on a public agent becomes a headline. Safety layers protect users, especially minors, and shield companies from liability.
Real-World Analogy
Content safety is a bouncer at the door — most guests pass, but harmful content doesn't get served to users.
Visual Workflows
What is Content Safety?
Example
Scenario
Agent asked for harmful instructions; moderation returns `blocked: violence`; agent responds with policy-safe refusal.
Solution
In Security & Guardrails, apply Content Safety to this scenario: Agent asked for harmful instructions; moderation returns `blocked: violence`; agent responds with policy-safe refusal. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.
Practice Task
Do this before moving to the next module — reading alone is not enough.
Open the Code Walkthrough below and run it locally. Change one parameter related to Content Safety (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

Common Mistakes
- Treating Content Safety as a black box without evaluation
- Ignoring cost and latency in production
- Skipping error handling for content safety
