shipping-and-launch

shipping-and-launch is a skill for Claude Code from peterblazejewicz/claude-plugins. It costs 95 tokens per session (5,024 once invoked), scanned A, original, MIT.

A guide for releasing .NET and C# systems to production safely. It combines pre-release checks with monitoring, staged rollouts, feature flags, and plans for undoing database or application changes.

In plain words
What is it for?
Use it before deploying ASP.NET Core or Blazor changes, releasing Avalonia or MAUI applications, running production EF Core migrations, publishing NuGet packages, or opening a beta.
Why use it?
It reduces the impact of launch problems by detecting issues early, releasing changes gradually, and keeping a recovery path ready.

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

shipping-and-launch 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 10d 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.

Shipping and Launch

Overview

Ship with confidence. The goal is not just to deploy — it's to deploy safely, with monitoring in place, a rollback plan ready, and a clear understanding of what success looks like. Every launch should be reversible, observable, and incremental.

When to Use

  • Deploying a feature to production for the first time
  • Releasing a significant change to users (ASP.NET Core service update, Blazor app revision, Avalonia/MAUI desktop release)
  • Running an EF Core migration against a production database
  • Publishing a new NuGet package version
  • Opening a beta or early access program
  • Any deployment that carries risk (all of them)

The Pre-Launch Checklist

Code Quality

  • All tests pass (dotnet test unit + integration, plus E2E if present)
  • dotnet build -warnaserror is clean (no analyzer diagnostics suppressed by accident)
  • dotnet format --verify-no-changes is clean
  • Code reviewed and approved
  • No TODO comments that should be resolved before launch
  • No Debug.WriteLine or stray Console.WriteLine debugging statements in production code paths (use ILogger<T> at the correct level)
  • No [Fact(Skip = "…")] on tests that guard the behaviour you're shipping
  • Error handling covers expected failure modes; OperationCanceledException is not swallowed

Security

  • No secrets in code, appsettings.json, or git history
  • dotnet list package --vulnerable --include-transitive shows no Critical or High vulnerabilities (or documented allowlist entries with review dates)
  • Input validation on all user-facing endpoints (FluentValidation / DataAnnotations / MediatR pipeline)
  • [Authorize] / RequireAuthorization() on every endpoint except explicitly-public ones
  • Security headers configured (CSP, HSTS, X-Content-Type-Options, X-Frame-Options)
  • Rate limiting on authentication endpoints (AddFixedWindowLimiter)
  • CORS configured to specific origins (not AllowAnyOrigin() with credentials)
  • ASP.NET Core Data Protection key ring is persisted and shared across instances (Azure Key Vault, Redis, or file share)

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.
