ai-character-checker-all-in-one

ai-character-checker-all-in-one is a skill for Claude Code from gpsnmeajp/ai-character-checker. It costs 193 tokens per session (3,678 once invoked), scanned A, original, CC0-1.0.

An all-in-one skill for analyzing, repairing, improving, transforming, or creating AI character settings and prompts. Its scoring and analysis models are the author's unverified hypotheses, so results are reference information rather than scientific findings.

In plain words
What is it for?
Use it to assess a character, prompt, or AI-generated self-description; check stability, role fit, cultural context, role-play demands, and failure modes; improve an existing character; or design and transform one.
Why use it?
It helps identify why an AI character may behave inconsistently or fail to follow its intended role. It also provides a structured way to revise the character or prompt when the user knows what needs to change.

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

ai-character-checker-all-in-one 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 12d 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.

概要

このスキルは、AIキャラクターに関する 13の専門スキル を1つに統合したオールインワンスキルである。 各スキルの詳細な手順・理論は references/ ディレクトリ内のファイルに格納されている。

なお、各スキルの分析フレームワーク・用語・スコアリング体系は作者独自の仮説的モデルに基づくものであり、学術的・科学的に実証されたものではない。工学的用語は概念の借用であり、元の定義とは異なる場合がある。各スキルの結果は参考情報として扱うこと。この旨をユーザーへの出力に含めること。


動作フロー

Step 1: 状況を把握する

ユーザーのメッセージと添付ファイルを確認し、以下の2点を判定する。

A. 手元に何があるか(入力データの種類)

データ種別 判定の目安
キャラクター設定(創作向け) 性格・外見・バックストーリーなどの文章的設定
AIプロンプト(システムプロンプト) AIに与えるための指示書形式のテキスト
蒸留結果(AI自己記述) AIが実際にそのキャラを演じた後の自己紹介・自己説明文
何もない データが提供されていない

B. 何をしたいか(目的)

目的カテゴリ 具体的な発言例
診断 「分析して」「診断して」「どんなキャラか見て」「危ないか確認して」
修正・改善 「直して」「安定させて」「より良くして」「崩壊しないようにして」
新規作成 「キャラを作って」「新しいAIキャラを設計して」
変換 「日常系に変えたい」「引退キャラにしたい」「別の方向に転換したい」
不明 目的が読み取れない、または複数の目的が混在している

Step 2: ルーティング判定

A・B の両方が明確な場合は Step 3 へ直接進む。 どちらかが不明な場合は Step 4 のヒアリングを行う。


Step 3: リファレンス読み込みと実行

下表を参照し、対応する references/ ファイルを読み込んで実行する。

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.
