cadence-ship

cadence-ship is a skill for Claude Code from abstractonion/cadence. It costs 26 tokens per session (248 once invoked), scanned A, original, MIT.

A release checklist for reviewing, validating, and committing the current code change. It includes checking changed files, linting, type checking, runtime verification, and preparing a commit.

In plain words
What is it for?
Use it when a change is ready to ship, to inspect the diff, run the project's checks, verify behavior, stage only relevant files, and propose a commit message.
Why use it?
It catches code-quality and runtime problems before the change is committed. It also prevents unrelated files from being included and stops when a required check fails.

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

cadence-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 11d 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.

What it actually says

Ship

You are shipping the current change this turn. Walk the sequence in order and do not skip steps: (1) review the working tree and refuse to stage any file unrelated to the stated change — name what you are excluding and why; (2) if two or more subagents completed on the same branch, run verify-parallel-integration on the combined diff before lint, runtime checks, or commit; (3) run the project's linter and type checker, fix only what you introduced; (4) run runtime verification and return the evidence bundle per verify-with-runtime; (5) stage the surgical set and propose a commit message; (6) if the session surfaced a non-obvious lesson, offer /reflect in one line — do not block ship on it. Stop and surface any failure before moving to the next step. Do not push.

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.
