ship

This skill does not implement the ship loop. It launches ${CLAUDE_PLUGIN_ROOT}/workflows/ship.js on the Workflow runtime. Implementing waves, review, remediation, verification, or a commit from this conversation is a bug.

The loop lives in that script on purpose: a skill is instructions a model can talk itself out of, and ship is sold as a run that asks nothing. Keep it that way.

Default is lean: waves → unit verify → commit. Adversarial review, handoff artifacts and conformance are opt-in. --strict restores the previous full loop.

1. Parse arguments

From $ARGUMENTS (or the Skill args payload) build an object. Prefer { change: "<name>" }. A bare string or a one-element array is also a change name — the script accepts all three — but never omit the name when the user gave one. A nameless validate against several active changes is a halt, not a prompt.

Pass a shape flag only when the user asked for one. Absent both, the classifier recommends a shape and the planner honours it inside a published envelope; the plan preview names the mode and why before a single implementer is spawned, so there is nothing to decide here. --solo and --waves together is a halt, not a preference to resolve.

The task shape is a different decision and has its own default: absent --tdd and --no-tdd, the CLI reads it from the Failing tests first heading /interlock:spec writes into tasks.md, so a change authored test-first runs that way with no flag at all and every other change is planned exactly as before. Pass a flag only to override the file. --tdd and --no-tdd together is a halt, for the same reason --solo --waves is.

Do not invent --strict because the change looks large. Continuity (spec --continue) also launches default lean unless the user passed a tail flag.

2. Launch the workflow

If the Workflow tool is available, this skill invocation is your authorization. Call it once, then stop. Do not narrate the loop. Do not implement tasks. Do not commit yourself.

Workflow({
  scriptPath: "${CLAUDE_PLUGIN_ROOT}/workflows/ship.js",
  args: { change: "<name or omit>", mode: "checkpoint" | "continue", flags: ["..."], pluginRoot: "${CLAUDE_PLUGIN_ROOT}" }
})

When it returns, you are done. Print the summary. Do not call Workflow again in this conversation. Leftover - [ ] boxes after a run are a report, not authorization to call Workflow again — those are failed or unticked tasks, and a second ship is a full new 20+ agent run. Only a new user message that explicitly asks to ship leftover tasks (or /interlock:ship again) is a relaunch.

If a /goal is active, it is satisfied when the transcript contains GOAL MET: interlock ship. Leftover checkboxes do not continue the goal. Do not launch another Workflow to "finish the goal." Do not invoke /goal from this skill.

mode matters more than it looks. The outcome corpus compares continuity runs against checkpoint runs; a continuity run filed as a checkpoint makes that comparison say the opposite of the truth.

If the run reports command not found for interlock, this session predates the plugin and its PATH has no plugin CLI. Say so, ask for a new session, and do not launch again.

3. If the Workflow tool is not available

Halt. Do not fall back to implementing the change in this conversation.

/interlock:ship needs Claude Code v2.1.154+ with Dynamic workflows enabled (/config). They are also off under disableWorkflows, org policy, CLAUDE_CODE_DISABLE_WORKFLOWS, or a Pro plan that has not turned the row on. Some IDE surfaces never expose the Workflow tool.

Tell the user that, and that everything else in Interlock still works — spec, the reviews, commit. Do not offer to "just start on the first task".

There is a second, experimental host — cli/interlock-run, which runs the same loop over a vendor coding CLI the user names (--host claude | acp | codex | qwen), --strict included: every step, the review and remediation rounds and the handoff among them, is emitted by interlock run and interpreted there as it is here. It is still a separate binary this skill never invokes, and it is still not a fallback for a missing Workflow tool. A user runs it themselves from a terminal; /interlock:ship is Claude Code only, and the runner refuses --host workflow from the other side.
