ship

ship is a skill for Claude Code, Codex from ariaxhan/kernel-claude. It costs 46 tokens per session (1,717 once invoked), scanned A, original, MIT.

A release checklist for shipping code changes. It checks the repository, validates the changes, reviews them, then pushes and tags the release.

In plain words
What is it for?
Use it when preparing a plugin or project release, especially when multiple loaders, installation steps, or user-owned files need testing.
Why use it?
It catches branch, validation, compatibility, installation, upgrade, and recovery problems before changes are published.

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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sequence

  1. Preflight

    • git status --porcelain — clean? If not: ask user to commit, stash, or abandon.
    • git branch --show-current — matches intent? Wrong branch → stop.
    • git log --oneline {main}..HEAD — commit range matches what you think you're shipping?
    • (gate: any mismatch → AskUserQuestion before continuing)
  2. Validate

    • Invoke /kernel:validate (spawns validator agent, full 9-gate safety chain).
    • If unavailable: run project's nearest configured command (see reference/ship-research.md for equivalents).
    • (gate: any FAIL → stop; report which gate; do NOT push)
    • For plugins that support multiple loaders, validate each loader's schema independently and exercise one installed payload per loader. A shared file parsing successfully is not proof that its armed behavior is equivalent.
    • Run install, supported upgrade, and documented recovery commands in a disposable plugin/cache copy from outside the source checkout. Assert user data and user-owned files are unchanged.
    • Put an explicit resource ceiling around heavyweight suites when available; a release gate must fail loudly instead of exhausting the host machine.
  3. Review

    • Tier 1 (1–2 file changes, low risk): self-review via Big 5 from skills/quality/SKILL.md.
    • Tier 2+: invoke /kernel:review (spawns reviewer agent, >80% confidence threshold).
    • (gate: REQUEST CHANGES → stop; address feedback; restart from step 2)
    • (gate: COMMENT → AskUserQuestion: "Address now, ship anyway, or hold?")
    • (gate: APPROVE → continue)
  4. Push

    • Feature branch (feat/*, fix/*, chore/*, etc.): git push (or git push -u origin {branch} if upstream not set).
    • main / master: STOP. AskUserQuestion required. (NEXUS I0.8)
    • Detached HEAD or unexpected state: stop; investigate.
    • (gate: push rejected / non-fast-forward → surface to user; do NOT force-push)
  5. Version + Tag (on a release)

    • Semver: patch=fix, minor=feature or behavior-preserving refactor, major=breaking. Confirm the number with the user.
    • Bump ALL canonical declarations in one shot: scripts/bump-version.sh X.Y.Z updates .claude-plugin/plugin.json, .claude-plugin/marketplace.json, governance/kernel.md.tmpl, regenerates AGENTS.md and CLAUDE.md, and updates skills/help/SKILL.md. NEVER hand-edit one location — drift fails test_version_sync_all.
    • Human-author the release prose the script does NOT touch: the plugin/marketplace description highlight + a CHANGELOG.md entry (## [X.Y.Z] - DATE + Added/Changed/Fixed).
    • (gate: bash tests/run-tests.sh green — test_version_sync_all confirms no stale version anywhere.)
    • If a native manifest validator rejects required safety metadata, do not weaken the safety metadata or hand-author an unvalidated manifest. Keep the proven compatibility loader, record the limitation, and defer the native manifest until both schemas can be satisfied.
    • Tag (only if user requested a tagged release): git tag -l to avoid clobber → git tag -a v{X.Y.Z} -m "{summary}"git push origin v{X.Y.Z}.
    • Before upgrading the installed plugin on this machine: pgrep -fl codex. The upgrade deletes the old cache directory under a live session's feet and every hook in that session exits 127 until it restarts. Name the live sessions in the handoff and say they need a restart; never report "upgraded" as if it covered them (docs/upgrading.md, 2026-08-27).
  6. Human pass (any user-facing release: app build, deploy, anything a person will touch)

    • Load skills/human-pass/SKILL.md and write the guide for THIS build: literal controls, paste-ready inputs, expected outcome per step, worst case first, bundled to one sitting with the time cost stated.
    • Hand it over and wait. The build is not shipped, it is awaiting verdict.
    • (gate: no guide, or no recorded verdict → the release is NOT done. Say "awaiting your pass on ", never "shipped". A green pipeline is not a person having used the thing.)
    • Findings come back as prose; YOU convert them into issues, not the human.
    • Record the verdict as a state-change receipt on the release issue, naming what it unlocks (next build, submission, deploy promotion).

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

ship is a skill published in the GitHub repository ariaxhan/kernel-claude (12 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 1,717 once invoked, about $0.0002 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.
