Before sending the prompt to the agent, the middleware checks the app and user metadata against Purview's protection scopes and evaluates all the `ChatMessage`s in the prompt. +2. If the content was blocked, the middleware returns a `ChatResponse` or `AgentRunResponse` containing the `BlockedPromptMessage` text. The blocked content does not get passed to the agent. +3. If the evaluation did not block the content, the middleware passes the prompt data to the agent and waits for a response. +4. After receiving a response from the agent, the middleware calls Purview again to evaluate the response content. +5. If the content was blocked, the middleware returns a response containing the `BlockedResponseMessage`. + +The user id from the prompt message(s) is reused for the response evaluation so both evaluations map consistently to the same user. + +There are several optimizations to speed up Purview calls. Protection scope lookups (the first step in evaluation) are cached to minimize network calls. +If the policies allow content to be processed offline, the middleware will add the process content request to a channel and run it in a background worker. Similarly, the middleware will run a background request if no scopes apply and the interaction only has to be logged in Audit. + +## Exceptions +| Exception | Scenario | +| --------- | -------- | +| PurviewAuthenticationException | Token acquisition / validation issues | +| PurviewJobException | Errors thrown by a background job | +| PurviewJobLimitExceededException | Errors caused by exceeding the background job limit | +| PurviewPaymentRequiredException | 402 responses from the service | +| PurviewRateLimitException | 429 responses from the service | +| PurviewRequestException | Other errors related to Purview requests | +| PurviewException | Base class for all Purview plugin exceptions | + +Callers' exception handling can be fine-grained + +``` csharp +try +{ + // Code that uses Purview middleware +} +catch (PurviewPaymentRequiredException) +{ + this._logger.LogError("Payment required for Purview."); +} +catch (PurviewAuthenticationException) +{ + this._logger.LogError("Error authenticating to Purview."); +} +``` + +Or broad + +``` csharp +try +{ + // Code that uses Purview middleware +} +catch (PurviewException e) +{ + this._logger.LogError(e, "Purview middleware threw an exception.") +} +``` diff --git a/dotnet/src/Microsoft.Agents.AI.Purview/ScopedContentProcessor.cs b/dotnet/src/Microsoft.Agents.AI.Purview/ScopedContentProcessor.cs new file mode 100644 index 0000000000..454da2d549 --- /dev/null +++ b/dotnet/src/Microsoft.Agents.AI.Purview/ScopedContentProcessor.cs @@ -0,0 +1,345 @@ +// Copyright (c) Microsoft.
