Azure Durable Task Skill

This skill provides expert guidance for Azure Durable Task. Covers best practices, decision making, architecture & design patterns, limits & quotas, configuration, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category	Lines	Description
Best Practices	L34-L42	Patterns and guidance for robust orchestrator design: constraints, retries, eternal/continue-as-new flows, external event handling, and singleton orchestration techniques.
Decision Making	L43-L48	Guidance on when to use Durable Functions vs raw Durable Task SDK, and how to compare and choose durable storage providers/backends for orchestrations.
Architecture & Design Patterns	L49-L56	Patterns for orchestrating Durable workflows: fan-out/fan-in, human approval steps, long-running monitors, and function chaining design and implementation.
Limits & Quotas	L57-L62	Configuring orchestration status size/retention limits, querying status, and monitoring Durable Task Scheduler action metrics, performance, and billing impacts.
Configuration	L63-L68	Configuring Durable Task hubs storage (connection, scaling, reliability) and using instance management APIs to query, control, and manage orchestration instances.
Deployment	L69-L72	Guidance on safely deploying Durable orchestrations using versioning strategies, handling breaking changes, and managing upgrades without disrupting running workflows.

Design fan-out/fan-in and human interaction workflows in Durable Task
Configure error handling, retries, and external event handling in orchestrations
Set up and manage Durable Task hubs storage and instance APIs

Quality Notes

Well-structured category index with clear line ranges enables efficient agent navigation of reference content
Explicit instructions for agents on when to fetch remote documentation vs. reading local sections
Clear metadata timestamp guidance helps agents recognize when documentation may be outdated
Comprehensive coverage of Azure Durable Task domain with well-organized topic tables linking to official Microsoft Learn documentation
Falls short of providing inline reference content—relies entirely on external documentation fetches, limiting offline capability and increasing latency
No error handling guidance for documentation fetch failures or network unavailability
Category index references lines (L34-L72) but the actual reference content is not included in the skill file itself
No examples of orchestration code patterns, configuration snippets, or deployment strategies—only links to external resources
Skill serves more as a documentation router than a self-contained knowledge base
License file is included but is standard CC-BY 4.0 and not specific to this skill's content
