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

kyosei 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.

How it starts

The opening of the file, as written. The whole thing — 504 lines — stays where its author put it; the contents beside it link to each section on GitHub.

コマンドの実行方法

このスキルはnode <プラグインルート>/dist/bin/*.js形式でヘルパーコマンドを実行します。 Claude Codeはコマンド例中の変数CLAUDE_PLUGIN_ROOTの参照を絶対パスへ展開しますが、 展開されず文字通りのまま残っている環境(OpenCodeなど)ではこの形式は動きません。 その場合は代わりにPATH上のget-review-infosubmit-reviewを同じ引数で実行してください。

get-review-infoでの情報の取得

以下のコマンドでレビューに必要な情報を取得して、 用途別のファイルに書き出します。

node ${CLAUDE_PLUGIN_ROOT}/dist/bin/get-review-info.js $ARGUMENTS

標準出力にはレビュー情報自体ではなく、 書き出したファイルの絶対パスを持つJSONが1行だけ返されます。 出力をtailやパイプなどで加工せず、 JSON全体をそのまま受け取ってください。

以下は出力例です。

{
  "context": "/run/user/1000/coding-agent-work/kyosei/review-info-example/context.json",
  "patch": "/run/user/1000/coding-agent-work/kyosei/review-info-example/changeset.patch",
  "commits": "/run/user/1000/coding-agent-work/kyosei/review-info-example/commits.log",
  "changesetMetadata": "/run/user/1000/coding-agent-work/kyosei/review-info-example/changeset-metadata.json",
  "conversation": "/run/user/1000/coding-agent-work/kyosei/review-info-example/conversation.json",
  "previousReview": "/run/user/1000/coding-agent-work/kyosei/review-info-example/previous-review.json",
  "incrementalChangeset": "/run/user/1000/coding-agent-work/kyosei/review-info-example/incremental-changeset.json"
}

返されたパスのファイルをReadツールで直接読んでください。 レビュー情報を1つのJSONへ結合したり、 一部を取り出すためにシェルコマンドで加工したりしないでください。

パスJSONの解釈

context

context.jsonへのパスです。

context.outputフィールドで出力先を判別します。

"github"

GitHub出力。 結果はGitHub PRにインラインコメントとして投稿されます。 hostpr(owner, repo, prNumber)が含まれます。

"local"

ローカル出力。 結果はターミナルに直接出力されます。 ブランチに紐付くPRが特定できた場合はprが含まれます。

patch

レビュー対象の差分をdiffフォーマットで保存したchangeset.patchへのパスです。

commits

コミットログを保存したcommits.logへのパスです。

changesetMetadata (headCommitIdが存在する場合のみ)

headCommitIdを保存したchangeset-metadata.jsonへのパスです。 主にGitHub出力時に含まれます。

conversation (PRが特定できた場合のみ)

PRの既存コメント・レビュー情報を保存したconversation.jsonへのパスです。 GitHub出力モードでは常に含まれます。 ローカル出力モードでもブランチに紐付くPRがあれば含まれます。 PRが特定できない場合はパスJSONから省略されます。

トップレベルにPR自体の情報(title, body, author, urlなど)があり、 以下の3つのサブフィールドがあります。

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.
