ship-cycle

ship-cycle is a skill for Claude Code from subinium/vibesubin. It costs 202 tokens per session (8,838 once invoked), scanned A, original, MIT.

A release-management skill that turns a set of software improvement requests into specified issues, version milestones, and tagged releases. It uses semantic versioning, where version numbers indicate the kind of change, and GitHub Flow, a branch-and-pull-request workflow.

In plain words
What is it for?
It is for writing bilingual issues, grouping them into versioned milestones, applying branch and commit rules, preparing changelogs, updating manifests, creating tags and GitHub releases, and maintaining an audit trail.
Why use it?
It removes guesswork from moving planned work through issues, milestones, code review, and a release while keeping the records connected.

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-cycle 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 8d 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 — 480 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ship-cycle

Turns improvement intent into shipped versions, deterministically: intent → issues → milestones = versions → tagged release. Direct-call only. Given a backlog (pasted notes, a /vibesubin sweep report, or a named scope), this skill writes a well-specified bilingual issue set, clusters items into semver milestones, dispatches the implementation to the correct vibesubin specialist, and — when a milestone closes — runs the full release pipeline end-to-end: changelog aggregation, manifest bump, annotated tag, GitHub release, audit trail. No interpretation, no flourish — the milestone state is the release state.

What this skill owns vs. hands off

Owns:

  • Issue specification — titles, bodies, labels, dependency links, language.
  • Milestone clustering — semver classification, cluster heuristics, cap enforcement.
  • Release pipeline — preflight checks, changelog aggregation, version bump, annotated tag, gh release create, verification.
  • Audit trail — close-comments on issues, milestone closure, release ↔ issue linkage.

Hands off:

  • Actual code changes — the fix itself is always another skill's job (refactor-verify, audit-security, etc.).
  • Release-note prosewrite-for-ai writes the user-facing narrative when the operator wants polish; this skill produces the functional-only scaffold.
  • CI wiringsetup-ci owns workflow files.

Not a replacement for:

  • write-for-ai — owns commit-message and PR-body style. This skill enforces when commits happen (Closes #N footer on each) and which PRs block a release, but not the prose inside them.
  • project-conventions — owns branch-strategy defaults. This skill suggests issue-<N>-<slug> branch names, but defers to an existing project convention when one exists.

Host check and track selection

ship-cycle runs in one of two tracks. Both follow the same 11-step methodology and the same conventions (see references/pr-branch-conventions.md); they differ only in where the audit trail lives.

Changes

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.
