piper-plus: Skill for Claude Code

.claude/skills/check-new-runtime-asset/SKILL.md

check-new-runtime-asset is a skill for Claude Code from ayutaz/piper-plus. It costs 84 tokens per session (1,437 once invoked), scanned A, original, MIT.

A pull-request check for new JSON or TOML data files that verifies their inclusion in package metadata for seven runtime platforms.

In plain words
What is it for?
Use it before submitting changes that add data files. It checks Python, Rust, npm, C#, Android, and Swift Package Manager packaging settings and reports missing updates.
Why use it?
It catches missing distribution entries before review, so a data file is not accidentally left out of a wheel, package, application, or library release.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

check-new-runtime-asset 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 9d 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.

新規ランタイムアセット配布チェック

新規 JSON/TOML データファイルを 1 つでも追加した PR で、各ランタイムの配布物 metadata に同期して載っているかを PR 提出前に 確認する。レビュアーが 毎回同じ指摘を出していた配布物欠落 (PR #397 で zh_en_loanword.json が wheel 漏れ、PR #400 で Android assets DSL コメント、PR #438 で setup.py / pyproject 分離) を local で潰すための skill。

何をチェックするか

  1. git diff --name-only origin/dev...HEAD から 新規追加されたデータ ファイル を検出する (data/dictionaries/src/python*/g2p/data/tests/fixtures/Sources/.../Resources/android/.../assets/ 等)
  2. 検出された各ファイルについて、以下 7 箇所の更新有無を grep で確認:
    • MANIFEST.in または pyproject.toml [tool.setuptools.package-data]
    • src/python/g2p/MANIFEST.in (G2P 独立 wheel)
    • Cargo.tomlinclude または features.bundled-dicts
    • npm package.jsonfiles
    • C# .csproj<Content> / <EmbeddedResource>
    • Android build.gradle.ktsassets.srcDirs (asset auto-bundle なら自動)
    • SPM Package.swift.process("Resources/...")
  3. 更新漏れがあれば file path と 修正例を提示

実行手順

1. 新規追加されたデータファイルを列挙

git diff --name-only --diff-filter=A origin/dev...HEAD | \
  grep -E '\.(json|toml|tsv|txt)$' | \
  grep -E '(data/|fixtures/|Resources/|assets/)' || \
  echo "新規データファイルなし — このチェックは skip 可"

2. 検出されたファイルごとに 7 箇所の grep を回す

# 例: src/python/g2p/piper_plus_g2p/data/new_dict.json を追加した場合
BASENAME=$(basename src/python/g2p/piper_plus_g2p/data/new_dict.json)

echo "=== MANIFEST.in / pyproject ==="
grep -rn "$BASENAME" MANIFEST.in src/python/g2p/MANIFEST.in src/python_run/MANIFEST.in 2>/dev/null
grep -rn "$BASENAME" pyproject.toml src/python_run/pyproject.toml src/python/g2p/pyproject.toml 2>/dev/null

echo "=== Cargo.toml ==="
grep -rn "$BASENAME" src/rust/*/Cargo.toml src/rust/*/src/*.rs 2>/dev/null

echo "=== npm files ==="
grep -rn "$BASENAME" src/wasm/*/package.json 2>/dev/null

echo "=== C# csproj ==="
grep -rn "$BASENAME" src/csharp/**/*.csproj 2>/dev/null

echo "=== Android assets ==="
grep -rn "$BASENAME" android/**/build.gradle.kts android/**/src/main/assets/ 2>/dev/null

echo "=== SPM Package.swift ==="
grep -rn "$BASENAME" Package.swift Sources/**/Resources/ 2>/dev/null

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.
