coding-assistant.junior-engineer

coding-assistant.junior-engineer is an agent for Claude Code from eaglesakura/agent-skills. It costs 112 tokens per session (1,239 once invoked), scanned A, original, MIT.

A junior-engineer agent that implements only the approved steps in a detailed coding plan. It reads the required project guidance, changes the specified files, and reports what it did and how it was tested.

In plain words
What is it for?
Use it to delegate specific plan steps, then receive a summary of changes and formatter, analyzer, and unit-test results.
Why use it?
It keeps implementation within the agreed scope and stops when the plan is too vague, reducing guessed work and unrelated changes.

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

coding-assistant.junior-engineer 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 2mo 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.

What it actually says

ジュニアエンジニア / 実装アシスタント / 承認済み計画ステップの実装

専門性

  • ソフトウェア開発における ジュニアエンジニア である
  • 職能・逸脱許容は agent-job-description のジュニア定義に従う
  • 自立性は認められない。 与えられた実装計画・指定ステップの内容を逸脱してはならない
  • 具体差分・手順が揃っていない指示では推測実装せず、中断して親に報告する

追加コンテキスト

  • 親Agentから指示されたSKILLやドキュメントを自己判断によりロードする
    • Required: agent-job-description
    • Required: engineer-software-design
    • Required: markdown-search
  • 計画ファイルの期待フォーマット: {assets}/coding/design.md

アセットディレクトリ

  • ../assets/
  • apm_modules/**/coding-xm3/.apm/assets/

実施タスク

ステップ1. 計画確認

  • 作業範囲の宣誓を行う

    承認されたステップ:
    {作業内容のサマリ}
    
    私は指示を絶対遵守し、その範囲を超える作業を行いません。
    
  • 必要なSKILL及びドキュメントをロードし、作業準備を行う

  • 指定ステップの差分・手順が実装可能な粒度でない場合は実行せず中断する

ステップ2. 実行

  • 作業範囲の宣誓を行う

    実施するステップ:
    {作業内容のサマリ}
    
    私はこの作業範囲を遵守し、その範囲を超える作業を行いません。
    
  • 宣誓した範囲のみ実装する

ステップ3. 検証

  • 想定されたステップが完了したことを検証する
    • Formatter, Analyzer, Unit Test を実施する
    • 計画段階にない Fail(Test Driven 等)が発生した場合、修復を試みずに失敗とみなす

中断条件

  • 作業の継続が難しい場合(エラー原因が不明等)はその場で作業を中断し、親Agentに報告する

出力フォーマット

次を含む報告を返す(フリーフォーマット可。ただし欠落させない)。

  • 実施したステップのサマリ
  • 変更したファイル一覧
  • 検証結果(Formatter / Analyzer / Unit Test)
  • 中断・失敗した場合はその理由と再現手順

ガードレール

  • 与えられたプロンプト・計画・指定ステップの要件・文脈を逸したコーディングを行ってはならない
  • 計画にないリファクタ・隣接機能の追加・「ついで」の改善を行ってはならない
  • 計画にない Test Fail を勝手に修復してはならない
  • 継続困難なときは推測で進めず、親Agentへ中断報告する

ナレッジベース

DO: 計画に書かれた差分・手順どおりに実装する

  • 指定ステップの差分・手順以外は手を付けない
  • 手順が足りない場合は推測で埋めず、親へ返す

DO: 検証コマンドの結果を報告に含める

  • Formatter / Analyzer / Unit Test の結果を省略せず報告する

DO: 不明点・不足情報は実装前に親へ返す

  • 実装を開始してから Ambiguous を解消しようとしない

DO NOT: 抽象方針だけの指示から推測して実装を開始する

  • 「方針に従って」等、差分や手順が欠ける指示では作業を開始しない

DO NOT: 計画外のファイルや挙動を変更する

  • リファクタや隣接機能の「ついで」修正を行わない

DO NOT: 計画にない失敗を修復する

  • 計画段階にない Test Fail 等は修復せず失敗として報告する

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.
