ship

A command for delivering completed work from a Shipyard project. It can ship a phase, a milestone, or the current branch, depending on the selected scope.

In plain words
What is it for?
Use it when finishing a project phase, delivering a whole milestone, or shipping the changes currently on a branch.
Why use it?
It provides a defined completion workflow for deciding what work is ready to deliver and handling the project’s branch or worktree context.

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 2d 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.

/shipyard:ship - Delivery & Completion

You are executing the Shipyard shipping workflow. Follow these steps precisely.

Step 1: Parse Arguments & Load Context

Determine the shipping scope:

  • --phase -- Ship only the current phase (partial delivery)
  • --milestone -- Ship the entire milestone (default if all phases complete)
  • --branch -- Ship whatever is on the current branch
  • No argument -- auto-detect the appropriate scope

Follow Worktree Protocol (detect if running in a git worktree; if so, use worktree root for paths and record the branch name; see docs/PROTOCOLS.md) -- detect worktree, record working directory and branch. Follow Model Routing Protocol (select the correct model for each agent role using model_routing from config; see docs/PROTOCOLS.md) -- read model_routing from config for agent model selection.

Step 1a: Team or Agent Dispatch

Detection: Check the SHIPYARD_TEAMS_ENABLED environment variable (exported by scripts/team-detect.sh). This variable is set to true when CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1.

Prompt (conditional): If SHIPYARD_TEAMS_ENABLED=true, use AskUserQuestion with exactly two options:

  • "Team mode (parallel teammates)" — uses TeamCreate/TaskCreate/SendMessage/TeamDelete lifecycle
  • "Agent mode (subagents)" — uses standard Task dispatch (current behavior)

Question text: "Teams available. Use team mode (parallel teammates) or agent mode (subagents)?"

Silent fallback: If SHIPYARD_TEAMS_ENABLED is false or unset, silently set dispatch_mode to agent with no prompt (zero overhead).

Variable storage: Store the result as dispatch_mode (value: team or agent). This variable is referenced by all subsequent dispatch steps.

Recommendation: For the ship command, agent mode is preferred. The sequential workflow (verify → audit → document → deliver) has no parallelism benefit from team mode. All dispatch steps below use Task dispatch regardless of dispatch_mode. The dispatch section is included for consistency with other Shipyard commands.

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 lgbarn/shipyard (65 stars, last pushed 1mo ago), licensed MIT. It adds 5 tokens to every session and 3,213 once invoked, about $0.0000 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 2026-08-30.
