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 | $0.00044 | $0.02794 |
| Opus 5 | $0.00022 | $0.01397 |
| Sonnet 5 | $0.00009 | $0.00559 |
| Haiku 4.5 | $0.00004 | $0.00279 |
Grade A, and why
software-architecture 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 7d 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.

ソフトウェアアーキテクチャ
Clean ArchitectureとDDD(ドメイン駆動設計)の原則に基づく、対象プロジェクトの設計ガイドライン。
Domain層の実装パターン
本セクションのコード例は Next.js + Supabase + TypeScript スタックでの一例。Clean Architecture / DDD のレイヤ責務(Entity / Repository / Service の分離、Interface によるモック差し替え)は スタック非依存の普遍的な原則であり、構文・生成ファイル名・ハンドラ種別は採用スタックに読み替えること。 実際のレイヤ規約は common
ARCHITECTURE.mdを SSoT とする。
データフローの一例(4層構造):
DB型(database.types.ts) → Entity型(models/) → Service(service/) → Server Actions(app/*/actions.ts)
↓
Repository(repository/)
1. Entity層(models/)
型定義とクラスの併用パターン: 型で構造定義、クラスでビジネスロジックを実装する。
// domain/models/opportunity/index.ts
// 構造定義(Type)
export type OpportunityEntity = {
id: string;
title: string;
salary_min: number;
salary_max: number | null;
deleted_at: string | null;
};
// ロジック実装(Class)
export class Opportunity {
public readonly id: string;
public readonly salaryMin: number;
constructor(entity: OpportunityEntity) {
this.id = entity.id;
this.salaryMin = entity.salary_min;
}
isHighPay(): boolean {
return this.salaryMin >= 1000000;
}
isDeleted(): boolean {
return this.deletedAt !== null;
}
// Entity型 → UI型への変換
toJob(): Job {
return {
id: this.id,
salary: this.formatSalary(),
highPay: this.isHighPay(),
};
}
}
判断基準: ビジネスルールが含まれる場合はClass、単純なデータ構造ならTypeのみで十分。
2. Repository層(repository/)
Interface + 実装クラスパターン: テスト時のモック差し替えを可能にする。
// domain/repository/saved-agent/index.ts
export interface ISavedAgentRepository {
create(userId: string, agentId: string): Promise<SavedAgent>;
findByUserAndAgent(
userId: string,
agentId: string,
): Promise<SavedAgent | null>;
softDeleteByUserAndAgent(
userId: string,
agentId: string,
): Promise<SavedAgent | null>;
}
export class SavedAgentRepository implements ISavedAgentRepository {
private admin = createSupabaseAdmin();
async create(userId: string, agentId: string): Promise<SavedAgent> {
const { data, error } = await this.admin
.from('saved_agents')
.insert({ user_id: userId, agent_id: agentId })
.select()
.single();
if (error?.code === '23505') {
throw new Error('既に保存済みです');
}
if (error) throw error;
return SavedAgent.fromDatabase(data);
}
}
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.

software-architecture is a skill published in the GitHub repository careerchain-ys/stdd (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 2,794 once invoked, about $0.0002 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 2026-08-31.
