Add Durable Task Scheduler skill by greenie-msft · Pull Request #919 · microsoft/GitHub-Copilot-for-Azure

greenie-msft · 2026-02-13T18:14:35Z

Adds a new reference skill for the Durable Task Scheduler enabling Copilot to guide users through building reliable, fault-tolerant workflows on Azure.

The skill covers:

Framework selection (Durable Functions vs. Durable Task SDKs)
Local development with the DTS emulator
Workflow patterns: chaining, fan-out/fan-in, async HTTP, monitor, human interaction, and saga
Orchestration determinism rules and replay-safe logging
Azure deployment with Bicep and managed identity configuration
Error handling and retry policies

Assign Durable Task Data Contributor role to the deploying user's identity so they can access the DTS dashboard in the Azure portal. Without this, the dashboard returns 403 Forbidden. Reference: https://github.com/Azure-Samples/Durable-Task-Scheduler/blob/main/samples/infra/main.bicep#L81

I'm not convinced the changes to azure-deploy are actually necessary.

The DTS deployment guidance in azure-deploy was redundant with the Bicep patterns already in the azure-prepare DTS skill docs. Removed: - durable-task-scheduler-deploy.md recipe file - Reference line from azure-deploy SKILL.md - 'Invoke azure-deploy' pointers from DTS README.md and bicep.md

Thanks for the review! I've removed that file and any references that pointed to it.
