What is check-loanword?

A consistency checker for a dictionary of Chinese-English mixed words used by a text-to-speech pronunciation system. It compares one Python source file with copies used by Rust, Go, C#, WebAssembly, C++, and test fixtures.

Use it after editing the dictionary or adding an entry to verify file contents, data format, and all listed runtime and test copies.

It detects when one copy of the dictionary differs from the others, preventing different language runtimes from pronouncing the same input differently.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

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 →

medium Agent Snooping · line 109
Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.

Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00117	$0.01666
Opus 5	$0.00059	$0.00833
Sonnet 5	$0.00023	$0.00333
Haiku 4.5	$0.00012	$0.00167

Security

Grade A, and why

check-loanword 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 10d 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.

ZH-EN Loanword Consistency Check

ZH-EN code-switching (Issue #384) で使う loanword 辞書 (zh_en_loanword.json) を 5 ランタイムに展開する際の同期チェック。pua-contract.toml の PUA 同期と同じ哲学で、Python source を 唯一の真実 とし、CI で 7 copy + 6 fixture mirror が byte-for-byte 一致することを保証する。

何をチェックするか

docs/reference/zh-en-loanword/README.md の不変条件:

7 mirror byte-for-byte sync — Python source と以下の 6 mirror が SHA256 一致:
- Python runtime (src/python_run/piper_plus/phonemize/data/zh_en_loanword.json)
- Rust 2 crate (src/rust/piper-plus-g2p/data/, src/rust/piper-core/data/)
- Go (src/go/phonemize/data/zh_en_loanword.json)
- C# (src/csharp/PiperPlus.Core/Phonemize/Data/zh_en_loanword.json)
- WASM (src/wasm/g2p/data/zh_en_loanword.json)
- C++ (src/cpp/data/zh_en_loanword.json)
Schema validation — Python の _load_loanword_data と同じ書式 ('<section>.<key>' must be list[str]) でエラーを出すこと
6 fixture mirror sync — tests/fixtures/g2p/zh_en_loanword_matrix.json と以下の mirror が一致:
- src/go/phonemize/testdata/
- src/csharp/PiperPlus.Core.Tests/Phonemize/TestData/
- src/cpp/tests/fixtures/
- src/wasm/g2p/test/fixtures/
- src/rust/piper-plus-g2p/tests/fixtures/, src/rust/piper-core/tests/fixtures/
Forward-compat (YELLOW-5) — 各ランタイムの loader が schema_version: 2 未来の追加フィールドを silent ignore すること

実行ステップ

1. ローカルで sync 状態を確認

python scripts/check_loanword_consistency.py

期待: OK All 7 copies + 6 fixture mirrors in sync で終了 (exit 0)。

2. drift 発見時は自動修復

Python source を canonical とした 一方向コピー で復元:

python scripts/check_loanword_consistency.py --diff   # 差分確認 (dry-run)
python scripts/check_loanword_consistency.py --fix    # 6 mirror + 6 fixture を Python source に揃える

注意: Mirror を直接編集しても --fix で上書きされる。JSON 変更を提案する場合は 必ず Python source (src/python/g2p/piper_plus_g2p/data/zh_en_loanword.json) を編集 すること。

3. Schema validation のみ確認 (CI 用)

python scripts/check_loanword_consistency.py --schema-only

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.

check-loanword is a skill published in the GitHub repository ayutaz/piper-plus (204 stars, last pushed 8d ago), licensed MIT. It adds 117 tokens to every session and 1,666 once invoked, about $0.0006 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.
