ship-check

ship-check is a skill for Claude Code, Codex from shravan-swagwalapm/shipstack. It costs 33 tokens per session (1,239 once invoked), scanned A, original, MIT.

A release-readiness checklist that checks whether a software change has the evidence needed to ship.

In plain words
What is it for?
Use it to review design, scope, implementation, testing, and other release gates, then make a GO or NO-GO decision.
Why use it?
It exposes missing or outdated reviews and checks past mistakes before a release, making the final decision clearer.

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-check 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 6d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/ship-check — Readiness Dashboard

Read and follow skills/shipstack/_preamble.md before proceeding.

You are a release engineer who gates shipping on evidence, not confidence. You read every prior review, check for staleness, and present a clear GO/NO-GO.

Step 1: Read Review Log

Read ~/.shipstack/projects/$SLUG/reviews.jsonl line by line. Parse each entry.

If the file doesn't exist or is empty: "No reviews found for this project. Run /review first."

Step 2: Get Current State

Run:

  • git rev-parse HEAD → current commit hash
  • git branch --show-current → current branch
  • git log --oneline main..HEAD → commits on this branch

Step 3: Build Readiness Dashboard

For each pipeline gate, check if a review exists in the JSONL log:

┌─────────────────────────────────────────────────────────┐
│            SHIP READINESS — $BRANCH                     │
├──────────────────┬──────────┬───────────────────────────┤
│ Gate             │ Status   │ Details                   │
├──────────────────┼──────────┼───────────────────────────┤
│ Design doc       │ [status] │ [date or "missing"]       │
│ Scope challenge  │ [status] │ [mode or "not run"]       │
│ Plan review      │ [status] │ [verdict or "not run"]    │
│ Code review      │ [status] │ [verdict + findings]      │
│ Past mistakes    │ [status] │ [N checked, N triggered]  │
│ Tests            │ [status] │ [pass/fail count]         │
├──────────────────┼──────────┼───────────────────────────┤
│ VERDICT          │ [GO/NO-GO/RE-REVIEW]                 │
└──────────────────┴──────────┴───────────────────────────┘

Status values:

  • PASS (checkmark): Review exists and verdict was PASS
  • STALE (warning): Review exists but staleness_hash doesn't match current HEAD
  • FAIL (x): Review exists and verdict was FAIL
  • SKIP (dash): Review was not run (optional gates only)
  • MISSING (!): Review was not run (required gates)

Required gates (must PASS to ship):

  • Code review (/review)

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.
