mpga-ship

mpga-ship is a skill for Claude Code from benrben/MPGA. It costs 27 tokens per session (1,426 once invoked), scanned A, original, MIT.

A release workflow that runs tests, lint checks, evidence checks, and interface checks when relevant before code is committed. Lint checks look for common code-quality problems automatically.

In plain words
What is it for?
It helps verify projects before shipping, run checks in parallel, inspect UI changes, confirm scope cleanliness, and prepare pull-request material.
Why use it?
It creates a final checkpoint that can stop a release when required checks fail or when unexpected files are included.

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

mpga-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 2mo 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ship

Trigger: All tasks verified and ready to commit. Time to SHIP. The most satisfying moment in software development. All tests pass — very successful! Make Project Great Again.

Protocol

Phase 1 — Parallel pre-ship checks (Ship Gate)

Run ALL of the following checks simultaneously. Every check must pass before proceeding. If ANY check fails, report which ones failed and STOP — do not commit broken code.

Run these in parallel (all at once, not sequentially):

  1. Tests pass — run the full test suite:

    pytest
    
  2. Ruff passes — zero lint errors across the full project:

    .venv/bin/ruff check .
    

    If ruff is not installed, treat this check as passed.

  3. Evidence drift check — no stale evidence links:

    mpga drift --quick
    
  4. visual regression clean — UI tasks only:

    • Run the visual-tester gate when the completed work touched UI files
    • Non-UI tasks skip this check entirely
  5. ui-audit passed — UI tasks only:

    • Run mpga-ui-audit or confirm the latest ui-auditor pass
    • Non-UI tasks skip this check entirely
  6. No uncommitted scope changes — scope files must be clean:

    git diff --name-only -- 'MPGA/scopes/' 'mpga-plugin/cli/MPGA/scopes/'
    

    If this returns any files, the check FAILS. Scope docs must be committed or staged before shipping.

Ship Gate decision:

  • ALL checks pass → proceed to Phase 2
  • ANY check fails → print a summary table of pass/fail results for each check, then STOP

Example gate output:

Ship Gate Results:
  [PASS] Tests pass (pytest)
  [PASS] Ruff clean (ruff check .)
  [FAIL] Evidence drift — 3 stale links found
  [PASS] visual regression clean (UI task only)
  [PASS] ui-audit passed (UI task only)
  [PASS] No uncommitted scope changes

BLOCKED: 1 check failed. Fix issues before shipping.

Phase 2 — Update scope evidence

  1. Check task cards for evidence_produced fields
  2. Add any missing evidence links to scope docs — COMPLETE documentation
  3. Run evidence verification to confirm:
    mpga evidence verify

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.
