character-type-checker

character-type-checker is a skill for Claude Code from gpsnmeajp/ai-character-checker. It costs 45 tokens per session (5,580 once invoked), scanned A, original, CC0-1.0.

A character-analysis skill that scores a fictional character for everyday and dramatic stories, then measures the gap between outward behaviour and inner seriousness. It uses a 24-item checklist and groups the character into one of seven types.

In plain words
What is it for?
Use it when designing or reviewing fictional characters, choosing a story genre, or comparing how a character might work in light everyday scenes versus heavier drama.
Why use it?
It gives a structured way to judge whether a character fits a story’s tone instead of relying only on intuition. The scoring model is the author’s unverified theory, so results are guidance rather than scientific findings.

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

character-type-checker 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 11d 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.

Character Type Checker — 日常系/ドラマ系 適性判定スキル

概要

このスキルは、キャラクターの特性を6つの評価軸・計24項目でチェックし、 日常系適性スコア (N)ドラマ系適性スコア (D) を0〜100で算出する。 さらに、表面の振る舞いと内面の重さの落差を測る 表裏乖離指数 (G) を導出し、 3つの指標の組み合わせからキャラクターを7つの類型に分類する。

既存スキルとの関係

スキル アプローチ 本スキルとの関係
ai-character-6-type-checker 6軸統合簡易診断 本スキルをモジュール①として内包する。詳細な解説・深掘りが必要なときは本スキルを単体で使用する
character-role-analyzer 役割適性診断(CW) 本スキルが「ジャンル適性」を、character-role-analyzerが「役割の重さ」を診断する。両方使うと配置戦略の全体像が見える
ai-character-stability 制御工学的安定性診断 独立した診断だが、高Dスコア/高積極性と安定余裕の低下は間接的に相関する
character-burnout-converter バーンアウト後変換 変換の方向決定にN/Dスコア概念を活用する
stable-character-creator 安定キャラ設計・新規作成 キャラ設計時にN/D/G概念を世界観・トーン設計の制約として活用する

理論的位置づけに関する注意

本スキルで使用する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。診断結果はあくまで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。

判定フロー

1. ユーザーからキャラクター情報を受け取る
2. 情報が不十分なら最低限の質問で補完する(後述)
3. 6軸×4項目のチェックリストを内部で評価する
4. N スコア・D スコア・G(表裏乖離指数)を算出する
5. 7類型から該当する類型を判定し、結果レポートを出力する

情報収集(必要最低限)

判定に最低限必要な情報は以下の3点。ユーザーの入力からこれらが読み取れない場合のみ、 簡潔に質問する。すでに十分な情報があれば質問せずに判定に進む。

  1. キャラクターの基本的な性格(例:おっとり、熱血、ミステリアス…)
  2. 普段の行動パターンや日常の過ごし方(例:友達と放課後にだらだら、単独で鍛錬…)
  3. 他者との関係性の特徴(例:対等な友人関係、師弟関係、ライバル…)

作品名やキャラ名が提示された既存キャラの場合は、自身の知識から補完してよい。


評価チェックリスト(6軸 × 4項目 = 24項目)

各項目を以下の3段階で採点する:

記号 意味 点数
明確に該当する 2
部分的に該当 / 状況による 1
該当しない 0

軸1: 関係性の安定度(Relationship Stability)

この軸は「キャラクターの存在が周囲の人間関係をどの程度一定に保つか」を測る。 日常系の心地よさの核は「変わらない関係性」にあるため、最も重要な軸である。

# 項目 N寄り=◯ D寄り=◯
1-1 距離感の一定性 — 他者との距離感が一定で、急に近づいたり離れたりしない N
1-2 関係変革の衝動 — 関係性を変えたい(守りたい、壊したい、深めたい)という強い内的動機を持つ D
1-3 グループ内での代替可能性 — そのキャラがいなくても、グループの雰囲気が大きく変わらない(良い意味での「空気」になれる) N
1-4 秘密・隠し事の保有 — 他者に言えない重大な秘密や過去を抱えている D

軸2: 目的と動機の性質(Purpose & Motivation)

キャラクターが何のために行動するか。日常系キャラは「目的のない時間」を自然に楽しめるが、 ドラマ系キャラは明確なゴールが行動の原動力になる。

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.
