prefer-jq SKILL.md skillA

prefer-jq from ncaq/konoka is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add ncaq/konoka/prefer-jq@git:20260821.3b0109e

Pins git:20260821.3b0109e in mdr.lock. Pin the fingerprint instead.

Prefer jq over Python or other general-purpose scripting languages for reading, filtering, or transforming JSON. Use when extracting values from JSON, parsing an API response, or writing anything that would otherwise reach for Python's json module or a `node -e` one-liner.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# JSONの処理にはjqを優先する

JSONを読み取ったり、
絞り込んだり、
変換したりするだけの用事に、
Pythonなどの汎用スクリプト言語を持ち出さないでください。
`jq`を使ってください。

## 理由

汎用スクリプト言語は何でも出来てしまいます。
コマンドの実行を承認する人間は毎回スクリプトの中身を読んで安全性を判断しなければならず、
`Bash(python:*)`のような包括的な許可を出すことも危険です。
jqの出来ることはデータの変換にほぼ限られていて副作用が少ないため、
包括的な許可を出しやすく、
承認の手間が発生しません。

単にJSONを取り出したり整形したりするだけなら、
jqの方が短く書けて読みやすいという利点もあります。

汎用スクリプト言語のワンライナーは、
シェルのクォートとスクリプト側のクォートが干渉して壊れやすく、
リトライを繰り返す原因にもなります。

## 対比

値の取り出し。

```console
# 避ける
python3 -c 'import json,sys; print(json.load(sys.stdin)["items"][0]["name"])'
# 使う
jq -r '.items[0].name'
```

絞り込み。

```console
# 避ける
python3 -c 'import json,sys; d=json.load(sys.stdin); print("\n".join(x["name"] for x in d["items"] if x["active"]))'
# 使う
jq -r '.items[] | select(.active) | .name'
```

集計。

```console
# 避ける
python3 -c 'import json,sys; print(sum(x["size"] for x in json.load(sys.stdin)["items"]))'
# 使う
jq '[.items[].size] | add'
```

Pythonに限った話ではありません。
`node -e`や`ruby -e`や`perl -e`のような他の汎用言語のワンライナーも同様に避けてください。

## よく使うオプション

- `-r`: 文字列をクォートなしの生の値として出力します。シェル変数へ代入する時に使います。
- `-e`: 出力に応じて終了ステータスを変えます。最後の出力が`false`か`null`なら1、出力が一つも無ければ4になります。条件判定に使えます。
- `-n`: 入力を読まずにJSONを組み立てます。
- `-s`: 複数の入力をひとつの配列にまとめます。

How to install

The exact contents, by fingerprint
mdr add ncaq/konoka/prefer-jq@sha256:5cd6595b2dac51f5

The line at the top of this page pins the label git:20260821.3b0109e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
