azure-functions

azure-functions is a skill for Claude Code, Codex from managedcode/dotnet-skills. It costs 113 tokens per session (2,210 once invoked), scanned A, original, MIT.

A guide for building and changing Azure Functions in .NET, including how they run, connect to services, and manage long-running workflows. Azure Functions are small pieces of code that run in response to events such as messages, timers, or web requests.

In plain words
What is it for?
Use it to build, review, or migrate C# Azure Functions, add triggers and bindings, configure the host, and implement Durable Functions workflows that keep track of long-running work.
Why use it?
It helps avoid setup and design mistakes when choosing between the older in-process model and the isolated worker model. It also clarifies how dependency injection, service connections, and durable workflows should be configured.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

azure-functions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Azure Functions for .NET

Trigger On

  • working on Azure Functions in .NET
  • migrating from the in-process model to the isolated worker model
  • adding Durable Functions, bindings, or host configuration

Documentation

References

  • Patterns - Isolated worker patterns, Durable Functions patterns, advanced binding patterns
  • Anti-Patterns - Common Azure Functions mistakes and how to avoid them

Workflow

  1. Use isolated worker model for all new work:

    • In-process model reaches end of support on November 10, 2026
    • Runtime v1.x ends support on September 14, 2026
    • Target .NET 8+ for longest support window
  2. Detect current project shape:

    • Target framework and runtime version
    • Worker model (isolated vs in-process)
    • Binding packages and host configuration
  3. Use standard .NET patterns in isolated model:

    • Normal dependency injection
    • Middleware pipeline
    • IOptions<T> for configuration
    • ILogger<T> for logging
  4. For Durable Functions:

    • Validate orchestration determinism constraints
    • Handle replay behavior correctly
    • Use typed activity patterns
  5. Verify both local and deployment behavior.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
