Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00218 | $0.02331 |
| Opus 5 | $0.00109 | $0.01166 |
| Sonnet 5 | $0.00044 | $0.00466 |
| Haiku 4.5 | $0.00022 | $0.00233 |
Grade A, and why
breach-encapsulation-naming 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.

Breach Encapsulation Naming
getterを作るなら「カプセル化を破っている」と名前で叫べ。
核心原則
ドメインモデルのgetterには breachEncapsulationOf プレフィックスを付与し、カプセル化を破っていることを明示する。
| アプローチ | 特徴 | 効果 |
|---|---|---|
通常のgetter (getName()) |
気軽に使える | 濫用されやすい |
明示的なgetter (breachEncapsulationOfName()) |
使用時に「破っている」と意識 | 濫用を抑制 |
なぜこの命名規約が必要か
ジレンマ
- Tell Don't Ask原則: getterを使わず、オブジェクトに命じるべき
- 現実の制約: 永続化やJSON変換ではgetterが必要
- 問題: getterがあると、ビジネスロジックでも使ってしまう
解決策
getterを「長くて目立つ名前」にすることで：
- 使うたびに「これは例外的な使用だ」と意識させる
- コードレビューで発見しやすくなる
- 静的解析ツールで検出可能になる
命名パターン
基本形式
breachEncapsulationOf<PropertyName>()
言語別の例
// Java
public String breachEncapsulationOfName() { return this.name; }
public Money breachEncapsulationOfPrice() { return this.price; }
// Kotlin
fun breachEncapsulationOfName(): String = name
fun breachEncapsulationOfPrice(): Money = price
// TypeScript
breachEncapsulationOfName(): string { return this.name; }
breachEncapsulationOfPrice(): Money { return this.price; }
# Python
def breach_encapsulation_of_name(self) -> str:
return self._name
// Go
func (u *User) BreachEncapsulationOfName() string { return u.name }
// Rust
pub fn breach_encapsulation_of_name(&self) -> &str { &self.name }
適用判断フロー
getterが必要か？
↓
├─ NO → getterを作らない（Tell Don't Ask）
│
└─ YES → 対象は？
│
├─ 値オブジェクト → 通常のアクセサでOK
│ （イミュータブルかつ振る舞いが限定的なため）
│ 例: Money.amount(), UserId.value()
│
└─ エンティティ → breachEncapsulationOf を使用
│
└─ なぜ必要？
├─ 永続化/シリアライズ → ✅ 許容
├─ 表示/UI → ✅ 許容
├─ テスト → ✅ 許容
└─ ビジネスロジック → ❌ Tell パターンに変換
値オブジェクト vs エンティティ
| 種類 | 特徴 | getter方針 |
|---|---|---|
| 値オブジェクト | イミュータブル、等価性で識別 | 通常のアクセサ可（amount(), value()） |
| エンティティ | ミュータブル、IDで識別 | breachEncapsulationOf を使用 |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

breach-encapsulation-naming is a skill published in the GitHub repository j5ik2o/okite-ai (81 stars, last pushed 4mo ago), licensed MIT. It adds 218 tokens to every session and 2,331 once invoked, about $0.0011 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 2026-09-01.
