managedcode-communication

managedcode-communication is a skill for Claude Code, Codex from managedcode/dotnet-skills. It costs 114 tokens per session (1,424 once invoked), scanned A, original, MIT.

A .NET result-handling library for returning explicit success or failure objects from services and APIs, including structured error details.

In plain words
What is it for?
Use it to design service results, map errors to HTTP problem details, and connect result handling with ASP.NET Core, SignalR, or Orleans.
Why use it?
It reduces reliance on exceptions for expected failures and makes service responses easier to handle consistently across application boundaries.

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

managedcode-communication 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ManagedCode.Communication

Trigger On

  • integrating ManagedCode.Communication into services or APIs
  • replacing exception-driven result handling with explicit results
  • reviewing service boundaries that return success or failure payloads
  • documenting result-pattern usage across ASP.NET Core or application services
  • mapping application errors to RFC 7807 problem details, Minimal API results, SignalR filters, or Orleans call filters

Install

Use the package that matches the boundary. Current upstream release reviewed: v10.2.2.

dotnet add package ManagedCode.Communication
dotnet add package ManagedCode.Communication.AspNetCore
dotnet add package ManagedCode.Communication.Extensions
dotnet add package ManagedCode.Communication.Orleans

For pinned project files:

<PackageReference Include="ManagedCode.Communication" Version="10.2.2" />
<PackageReference Include="ManagedCode.Communication.AspNetCore" Version="10.2.2" />
<PackageReference Include="ManagedCode.Communication.Extensions" Version="10.2.2" />
<PackageReference Include="ManagedCode.Communication.Orleans" Version="10.2.2" />

Workflow

  1. Confirm the boundary where the library belongs:
    • service result contracts
    • application manager boundaries
    • API endpoints that translate results into HTTP responses
  2. Keep result creation and error mapping explicit instead of mixing exceptions, nulls, and ad-hoc tuples.
  3. Pattern-match result objects at the boundary that converts them into user-facing responses.
  4. Do not hide domain failures behind generic success wrappers.
  5. Configure framework integration only where it removes manual translation:
    • ConfigureCommunication() for ASP.NET Core logging and converters
    • WithCommunicationResults() for Minimal API endpoint or group conversion
    • Orleans or SignalR packages only when those runtime filters are actually in use
  6. Validate positive, negative, and error-path handling after integration.

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.
