ship

ship is a command for coding agents from peterblazejewicz/claude-plugins. It costs 27 tokens per session (2,020 once invoked), scanned A, original, MIT.

A pre-launch check for a .NET change that asks several specialist reviews to run in parallel and combines them into one decision about whether it is ready to release. It also includes a plan for undoing the change if needed.

In plain words
What is it for?
Use it before releasing a .NET change to review the code, security concerns, and operational readiness, then decide whether to launch or hold back.
Why use it?
Launching without checking code quality, security, and release risks can lead to failures after deployment. A single go/no-go result makes those risks easier to assess before launch.

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

ship 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 4d 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Invoke the dotnet-skills:shipping-and-launch skill.

/ship is a fan-out orchestrator. It runs three specialist personas in parallel against the current change, then merges their reports into a single go/no-go decision with a rollback plan. The personas operate independently — no shared state, no ordering — which is what makes parallel execution safe and useful here.

Phase A — Parallel fan-out

Spawn three subagents concurrently using the Agent tool. Issue all three Agent tool calls in a single assistant turn so they execute in parallel — sequential calls defeat the purpose of this command.

In Claude Code, each call passes subagent_type matching the persona's name field:

  1. code-reviewer — Run a five-axis review (correctness, readability, architecture, security, performance) on the staged changes or recent commits. Ground findings in .NET specifics: nullable-reference-type honesty, async/await correctness (no .Result / .Wait() on I/O paths), CancellationToken threading, DI lifetime correctness, EF Core N+1, MyApp.Core / MyApp.Infrastructure / MyApp.Contracts layering. Output the standard review template with file.cs:line references.
  2. security-auditor — Run a vulnerability and threat-model pass. Check OWASP Top 10 translated to ASP.NET Core / EF Core / Blazor equivalents, secrets handling (dotnet user-secrets / Key Vault / env), auth + policy-based authz ([Authorize], RequireAuthorization(), per-resource IDOR checks), FromSqlRaw injection, and dependency CVEs (dotnet list package --vulnerable --include-transitive). Output the standard audit report.
  3. test-engineer — Analyze test coverage for the change. Identify gaps in happy path, edge cases, error paths, cancellation, and concurrency scenarios — framed around the xUnit / MSTest runner the project uses and the relevant integration boundary (WebApplicationFactory<Program>, Testcontainers, Microsoft.Playwright, Avalonia.Headless.XUnit). Output the standard coverage analysis.

In other harnesses without an Agent tool, invoke each persona's system prompt sequentially and treat their outputs as if returned in parallel — the merge phase still works.

Constraints (from Claude Code's subagent model):

  • Subagents cannot spawn other subagents — do not let one persona delegate to another.
  • Each subagent gets its own context window and returns only its report to this main session.
  • If you need teammates that talk to each other instead of just reporting back, use Claude Code Agent Teams and reference these personas as teammate types (see ../references/orchestration-patterns.md).

Persona resolution. If you've defined your own code-reviewer, security-auditor, or test-engineer in .claude/agents/ or ~/.claude/agents/, those take precedence over this plugin's versions — /ship picks up your customizations automatically. This is intentional: plugin subagents sit at the bottom of Claude Code's scope priority table, so user-level definitions win by design.

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.

ship is a command published in the GitHub repository peterblazejewicz/claude-plugins (7 stars, last pushed 2mo ago), licensed MIT. It adds 27 tokens to every session and 2,020 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
