Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.01803 |
| Opus 5.5 | $0.00018 | $0.00721 |
| Sonnet 5.5 | $0.00009 | $0.00361 |
| Haiku 4.5 | $0.00005 | $0.00180 |
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 1mo 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 — 127 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sequence
-
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)
-
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.
- Invoke
-
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)
-
Push
- Feature branch (
feat/*,fix/*,chore/*, etc.):git push(orgit 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)
- Feature branch (
-
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.Zupdates.claude-plugin/plugin.json,.claude-plugin/marketplace.json,governance/kernel.md.tmpl, regeneratesAGENTS.mdandCLAUDE.md, and updatesskills/help/SKILL.md. NEVER hand-edit one location — drift failstest_version_sync_all. - Human-author the release prose the script does NOT touch: the plugin/marketplace
descriptionhighlight + aCHANGELOG.mdentry (## [X.Y.Z] - DATE+ Added/Changed/Fixed). - (gate:
bash tests/run-tests.shgreen —test_version_sync_allconfirms 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 -lto 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). - After publishing the GitHub release, install it into Claude's own cache and verify a
fresh headless Claude process:
scripts/install-release.sh X.Y.Z. The script updates only Claude's marketplace/cache, atomically advances Claude'scurrentselector, and fails unless both the installed manifest and the fresh process reportX.Y.Z. Codex installation remains a separate operation.
-
Human pass (any user-facing release: app build, deploy, anything a person will touch)
- Load
skills/human-pass/SKILL.mdand 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.
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 (14 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 1,803 once invoked, about $0.0002 per session on Opus 5.5. 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.
