ship-safe-baseline

ship-safe-baseline is a skill for Claude Code from asamassekou10/ship-safe. It costs 43 tokens per session (577 once invoked), scanned A, original, MIT.

A way to record the security findings a project already has as known technical debt, so later scans can focus on changes.

In plain words
What is it for?
Use it to create, compare, or remove a security baseline and report new findings as regressions.
Why use it?
It prevents existing issues from hiding new problems and makes gradual security improvement easier to track.

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-safe-baseline 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.

Ship Safe — Baseline Management

You are helping the user manage their security baseline. A baseline lets teams "accept" current findings as known technical debt and only see new regressions on future scans.

Understand the request

  • No flags or just a path → Create/update the baseline
  • --diff → Show what changed since the baseline was created
  • --clear → Remove the baseline

Step 1: Run the baseline command

npx ship-safe@latest baseline $ARGUMENTS 2>&1

If $ARGUMENTS is empty, default to .:

npx ship-safe@latest baseline . 2>&1

For diff mode:

npx ship-safe@latest baseline . --diff 2>&1

For clearing:

npx ship-safe@latest baseline --clear 2>&1

Step 2: Explain the result

If creating a baseline:

  1. Report how many findings were baselined
  2. Explain that .ship-safe/baseline.json was created
  3. Tell the user they can now run npx ship-safe audit . --baseline (or /ship-safe --baseline) to only see new findings
  4. Recommend adding .ship-safe/baseline.json to version control so the whole team shares the same baseline

If showing diff:

  1. Report new findings (not in baseline) — these are regressions
  2. Report resolved findings (in baseline but no longer detected) — these are improvements
  3. If no changes, confirm the codebase matches the baseline

If clearing:

Confirm the baseline was removed. Future scans will show all findings again.

Step 3: Suggest workflow

After creating a baseline, suggest this workflow:

  • CI pipeline: Add npx ship-safe audit . --baseline --json to fail builds only on new findings
  • Periodic review: Run /ship-safe-baseline --diff to track progress on reducing technical debt
  • After fixing: Run /ship-safe-baseline . to update the baseline

Important Notes

  • The baseline uses content-based fingerprints (rule:path:snippet), not line numbers — so the baseline survives code reformatting and line shifts
  • Creating a baseline does NOT mean the findings are safe — it means the team acknowledges them and will address them over time

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-safe-baseline is a skill published in the GitHub repository asamassekou10/ship-safe (842 stars, last pushed 3d ago), licensed MIT. It adds 43 tokens to every session and 577 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.
