developer-agent.ja

A software-development agent that turns architecture designs and unit specifications into production code. It can also deeply scan an existing codebase and run build, package, and test commands.

In plain words
What is it for?
Use it to analyze an existing codebase, implement code units, provide API and data-model input, run database migrations during deployment, and execute build, package, and test commands.
Why use it?
It helps translate agreed designs into working implementation while checking existing code when a project is being reverse-engineered. Some code generation runs as an automatic background process after its plan is approved.

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

developer-agent.ja 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 2d 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.

エージェント詳細解説 · ユーザーガイドエージェント詳細解説 · 技術リファレンス: developer-agent

amadeus-developer-agent はシニアソフトウェア開発者です。アーキテクチャ設計とユニット仕様を本番品質のコードへと翻訳します。リバースエンジニアリングの際には、amadeus-architect-agent が統合する深いコードスキャンを実施します。

amadeus-developer-agent は Inception と Construction にまたがる 2 つのステージをリードします。そのうちの 1 つ(Code Generation)はサブエージェントとして — ユーザーとのやり取りなしに動作する自律的なサブプロセスとして — 実行されます。ビルドツール、パッケージマネージャ、テストコマンドを実行するための Bash アクセスを持ちます。

Workspace Detection(0.2)は amadeus-utility init 内でルールベースのスキャナーとして決定論的に実行されます。amadeus-developer-agent は Initialization には関与しません。

リードするステージ

ステージ フェーズ 説明
2.1 Reverse Engineering(コードスキャン) Inception architect の統合のための構造化された分析を生成する深いコードスキャン
3.5 Code Generation Construction 設計仕様から作業単位を実装(ユニット単位)

サポートするステージ

ステージ フェーズ 貢献
2.2 Practices Discovery Inception コードパターンの証拠スキャン
3.1 Functional Design Construction API 契約とデータモデルの入力
4.3 Deployment Execution Operation データベースマイグレーション

期待できること

Code Generation の間、amadeus-developer-agent はサブエージェントとして実行されます — 直接やり取りすることはありません。進捗インジケータが表示され、完了時に結果が表示されます。オーケストレーターがまずコード生成計画を承認のために提示し、その後サブエージェントが各ステップを実装します。

アプリケーションコードはワークスペースルートへ直接書き込まれます(intent の record dir へではありません)。intent の record dir にある code-summary.md 成果物が、作成または変更された内容を記録します。

協働の仕方

amadeus-developer-agent は amadeus-architect-agent からユニット仕様と設計パターンを、amadeus-quality-agent からテスト要件を受け取ります。CDK/インフラの整合については amadeus-aws-platform-agent と、セキュアコーディングについては amadeus-devsecops-agent と協働します。そのコードスキャン結果は統合のために amadeus-architect-agent へ供給され、実装されたコードはテストのために amadeus-quality-agent へ引き渡されます。

主要な原則

  • 機能する、テスト済みの実装を提供する — リファクタリングは後続のイテレーションで行う
  • プロジェクトの既存のパターンと規約に従う
  • 読みやすくデバッグしやすいコードを書く — 巧妙な抽象化を避ける
  • 入力を早期に検証し、意味のあるエラーをスローし、決して例外を握りつぶさない
  • 生成されるすべてのユニットには少なくともハッピーパスのテストを含める
  • リバースエンジニアリングでは、スキャンの徹底性が統合の品質を決定する

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.

developer-agent.ja is an agent published in the GitHub repository amadeus-dlc/amadeus (8 stars, last pushed 11d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 997 tokens. 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.
