dotnet-managedcode-storage

dotnet-managedcode-storage is a skill for Claude Code, Codex from Postpartum-genushyacinthus29/dotnet-skills. It costs 45 tokens per session (407 once invoked), scanned A, a copy of dotnet-managedcode-storage, MIT.

A guide for ManagedCode.Storage, a .NET library that places one storage interface between an application and different file or object-storage providers.

In plain words
What is it for?
Use it to set up storage providers, containers, credentials, uploads, downloads, existence checks, and deletions through one application-facing contract.
Why use it?
It keeps provider-specific SDK calls and configuration from spreading throughout application code, making backend changes easier to manage.

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

dotnet-managedcode-storage 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 9d 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.

What it actually says

ManagedCode.Storage

Trigger On

  • integrating ManagedCode.Storage into a .NET application
  • reviewing how a project abstracts file or object storage
  • deciding whether to centralize storage provider differences behind one library
  • documenting upload, download, container, or blob-handling flows with ManagedCode.Storage

Workflow

  1. Identify the actual storage use case:
    • blob or file storage
    • provider abstraction across environments
    • app-service integration and configuration
  2. Verify whether the project wants one storage contract instead of provider-specific SDK calls scattered across the codebase.
  3. Keep application code dependent on the library abstraction, not directly on backend-specific storage SDKs unless a provider-only feature is truly required.
  4. Centralize provider configuration, credentials, and container naming in composition-root code and typed settings.
  5. Validate the real upload, download, existence-check, and deletion flows after wiring the library.

  B --> C["Provider-specific storage implementation"]
  C --> D["Blob or object storage backend"]

Deliver

  • concrete guidance on when ManagedCode.Storage is the right abstraction
  • wiring guidance that keeps provider concerns out of business code
  • verification steps for the storage flows the application actually uses

Validate

  • the project really benefits from a storage abstraction and is not hiding provider-specific behavior it still needs
  • storage configuration is centralized and explicit
  • code reviews check real read and write paths, not only registration snippets
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.
