implement

A command that carries out the tasks listed in tasks.md in dependency order. It reads the project plan and related design documents before changing the code.

In plain words
What is it for?
Use it to implement a planned feature, run the required checks, mark finished tasks, commit each completed task, and report remaining work or problems.
Why use it?
It provides a checklist-driven implementation process, updates completed tasks, and pauses when required checks fail or an error blocks progress.

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.

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

implement 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.

What it actually says

ユーザー入力

$ARGUMENTS

空でない場合、続行する前にユーザー入力を考慮する必要があります

目的

tasks.md に定義されたタスクを順次実行し、機能を実装する。

実行手順

1. コンテキスト初期化

{SCRIPT} を実行し、FEATURE_DIRAVAILABLE_DOCS を取得(パスはすべて絶対パス)。

2. チェックリスト検証

FEATURE_DIR/checklists/ が存在する場合:

  1. 各チェックリストファイルをスキャン
  2. 未完了項目(- [ ])をカウント
  3. 未完了がある場合は停止して確認:
    以下のチェックリストに未完了項目があります:
    - requirements.md: 3件未完了
    - security.md: 1件未完了
    
    続行しますか? (yes/no)
    
  4. ユーザーが no なら中断

3. ドキュメント読み込み

必須:

  • tasks.md(タスクリスト)
  • plan.md(技術スタック、プロジェクト構造)

任意:

  • data-model.md(エンティティ定義)
  • contracts/(API仕様)
  • research.md(技術決定)
  • quickstart.md(テストシナリオ)

4. タスク実行

tasks.md のタスクを順次実行:

実行ルール:

  1. フェーズ順に実行(Phase 1 → Phase 2 → ...)
  2. 各フェーズ内でタスクID順に実行
  3. [P]マーカーのあるタスクは並列実行可能
  4. 憲章の禁止事項を尊重(TDD必須等)
  5. 依存関係を確認してからタスク開始

タスク完了時:

  1. tasks.md のチェックボックスを更新: - [ ]- [x]
  2. 変更をコミット(Conventional Commits形式)
  3. 次のタスクへ進む

エラー発生時:

  1. エラー内容を記録
  2. 関連するタスクにブロッキングノートを追加
  3. ユーザーに報告して次のアクションを確認

5. フェーズ完了チェック

各フェーズ完了時:

  1. フェーズ内の全タスクが完了しているか確認
  2. 独立テスト基準が満たされているか確認
  3. 次のフェーズへの移行可否を報告

6. 完了報告

  • 完了したタスクID一覧
  • 残タスク一覧
  • 発生した問題(あれば)
  • 次の推奨アクション:
    • 残タスクがある場合: 続行を推奨
    • 全タスク完了: PRレビューまたは追加テストを推奨
    • 問題がある場合: 修正アクションを提案

ガイドライン

  • タスクは独立して実行可能であるべき
  • 各タスク完了後にコミット
  • TDD遵守(テスト→実装→リファクタの順)
  • 憲章違反を検出した場合は中断して報告
  • 大きなタスクは分割を提案

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.

implement is a command published in the GitHub repository akiojin/unity-mcp-server (34 stars, last pushed 9d ago), licensed MIT. It adds 34 tokens to every session and 906 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 2026-08-30.
