About Azure Content Understanding

Azure Content Understanding is a Microsoft Foundry service that uses generative AI to process unstructured documents, images, audio, and video into structured JSON or Markdown. It supports prebuilt and custom analyzers for content extraction, classification, and schema-based field extraction.

This preview extension exposes Content Understanding workflows through az cu, including analyzing files and URLs, managing analyzers and profiles, checking resource readiness, and generating Microsoft Foundry infrastructure. The extension source is maintained in Azure/content-understanding-toolkit.

Thank you for triggering the CI checks. Two validation jobs exposed the same packaging issue.

The extension directly imports azure.ai.contentunderstanding, but version 0.1.0b1 relied on the SDK being installed transitively through cu-cli-core. Our local and repository CI environments already had that transitive dependency available, which masked the missing direct dependency. The Azure CLI external-extension validation installs the published wheel in a cleaner environment and exposed the issue.

We are updating the extension to declare azure-ai-contentunderstanding>=1.2.0b3 directly. Because 0.1.0b1 is already published and immutable, we plan to release the correction as 0.1.0b2 on September 14, 2026, then update this PR with the new wheel URL, checksum, and generated metadata.
