Analyzed 155+ TODO comments and commented code blocks across the C# codebase to create a structured migration completion plan.

Deliverables

Migration Plan Documents

  • 8 Epic categories covering combat system, unit/pilot mechanics, UI, events, data persistence, VB6 legacy, performance, and bug fixes
  • ~70 specific issues sized for <1000 line PRs with implementation details, affected files, and test strategies
  • Epic breakdown example:
    • Epic 1 (Combat): 15-20 issues including dodge/parry attacks, support systems, combination techniques
    • Epic 2 (Unit/Pilot): 12-15 issues for skill validation, ability checks, transformation mechanics

Project Management Infrastructure

  • GitHub Projects setup guide with 5-column board (Backlog → Ready → In Progress → Review → Done)
  • Label taxonomy: Epic (8), Priority (4), Type (6), Size (5), Status (4)
  • 4-phase milestone schedule: Core features (Q2'26) → UI/UX (Q3'26) → Quality (Q4'26) → Optimization (Q1'27)

Automation Scripts

# Create standardized labels across priority/type/size dimensions
bash docs/scripts/create-labels.sh

# Generate 4-phase milestone structure
bash docs/scripts/create-milestones.sh

# Report completion metrics by epic/milestone/priority
bash docs/scripts/progress-report.sh

Issue Templates

  • Epic template: Groups 10-20 related features with effort estimation
  • Feature template: Single responsibility implementation with size constraints
  • Bugfix template: Reproduction steps and impact analysis

Fully Autonomous Copilot Agent

  • Single command operation (.github/copilot/autonomous-agent.md): Complete migration progression with just @copilot 移植を進行してください (Proceed with migration)
  • Zero human decision-making: Copilot auto-assesses current state, auto-selects next task, auto-implements, auto-tests, and auto-creates PRs
  • Self-contained intelligence: Uses only docs/ documentation and codebase - no setup required
  • Continuous operation mode: Can work autonomously until completion or blocker
  • 15 instruction examples (.github/copilot/copilot-instructions-examples.md): Optional fine-grained control for specific tasks
  • Complete operational manual (.github/copilot/agent-instructions.md): Detailed workflows for 4 specialized agent roles
  • Quick reference card (.github/copilot/quick-reference.md): Checklists and commands
  • Agent README (.github/copilot/README.md): Overview and quick start

🤖 Fully Autonomous Operation: Copilot works with minimal human thinking:

  • ✅ Single command: @copilot 移植を進行してください
  • ✅ Auto-decides: Next task, implementation approach, test strategy
  • ✅ Auto-executes: Issue creation, code implementation, test addition, PR creation
  • ✅ Auto-reports: Completion status, next task suggestion
  • ❌ No setup: GitHub Projects, labels, milestones
  • ❌ No detailed instructions: Copilot auto-decides from docs and codebase

Autonomous Agent Features:

  • Intelligent task selection: Priority matrix with dependency resolution
  • Self-correction: Auto-retry on test failures with alternative approaches
  • Progress tracking: Auto-generated reports every 5 tasks
  • Safety mechanisms: Never deletes working code, always adds tests
  • Traffic light system: Visual status indicators (🟢 ready, 🟡 caution, 🔴 blocked)

Example - Single Command:

@copilot 移植を進行してください

Copilot then autonomously:

  1. Assesses current state (checks issues, PRs, TODOs)
  2. Selects next highest-priority task
  3. Creates issue if needed
  4. Implements feature with tests
  5. Creates PR (≤1000 lines)
  6. Reports completion and suggests next task

Key Findings

High-concentration areas:

  • Unit.attackcheck.cs (13 TODOs): Attack type implementations
  • Unit.lookup.cs (9 TODOs): Ability/skill validation
  • Pilot.skill.cs (4 TODOs + 20 lines commented): Skill availability logic
  • QuestionCmd.cs (85 lines commented): User dialog system
  • Status.cs (200+ lines commented): Legacy VB6 rendering code

Estimated scope: 18-25k line changes over 12-18 months with 2-3 contributors working in parallel.

All documentation is bilingual (Japanese/English) and located in docs/ with quick start guide at docs/quick-start.md. Autonomous agent instructions are in .github/copilot/autonomous-agent.md.


💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers. Learn more Copilot coding agent tips in the docs.

@copilot 用意したドキュメントをCopilotが運用するためのインストラクションを整備してください。

Copilotエージェント用の運用手順書を整備しました(コミット 04cd455)。

.github/copilot/ に以下の3つのファイルを作成:

  1. agent-instructions.md - 完全な運用手順書(4つの専門エージェント役割の詳細)
  2. quick-reference.md - 日常業務用のクイックリファレンスカード
  3. README.md - ディレクトリの概要とクイックスタート

これらの指示書により、Copilotエージェントは以下を実行できます:

  • Issue作成(docs/issue-breakdown.mdから約70個のIssueを作成)
  • 機能実装(TODO解決、テスト追加、PR作成)
  • PRレビュー(品質チェック、移植計画との整合性確認)
  • 進捗管理(週次レポート生成、プロジェクトボード更新)

詳細は .github/copilot/README.md をご覧ください。

@copilot GitHub Projects等をセットアップすることなく、Copilotへの指示のみで作業が進行できる構成としてください。また、そのためのCopilotへの指示の例を示してください。

GitHub Projectsのセットアップなしに、Copilotへの指示のみで作業できる構成に変更しました(コミット 13535e8)。

追加内容:

  1. copilot-instructions-examples.md (15の具体的指示例)

    • Epic Issue作成
    • 機能実装(TODO解決)
    • PRレビュー
    • 進捗レポート生成
    • バグ修正
    • 一括Issue作成など
  2. 自己完結型運用

    • GitHub Projects不要
    • ラベル/マイルストーン手動作成不要
    • docs/のドキュメントとコードベースのみで動作

使用例:

@copilot Epic 1: 戦闘システム完成 のIssueを作成してください。

以下の情報を使用:
- タイトル: "Epic 1: 戦闘システム完成"
- 内容: docs/issue-breakdown.md の Epic 1 参照
- ラベル: type:epic, epic:combat, priority:high

@copilot 人間が考えることが多すぎます。コードベースやTODOを基本として「移植を進行してください」のみの指示で自律的に移植完了作業が進行するように設計してください。

完全自律型エージェントを追加しました(コミット 5a7dfc6)。

使用方法:

@copilot 移植を進行してください

この一文だけで、Copilotが以下を自動実行:

  • ✅ 現状評価(Issue、PR、TODOの確認)
  • ✅ 次タスク自動選択(優先度・依存関係を考慮)
  • ✅ 自動実装(Issue作成→コード実装→テスト追加→PR作成)
  • ✅ 進捗報告(完了内容、次タスク提案)

特徴:

  • 人間の判断は最小限(「進めてください」のみ)
  • セットアップ不要(GitHub Projects、ラベル、マイルストーン)
  • ドキュメントとコードベースから自動判断
  • 自己修正機能(テスト失敗時の自動リトライ)
  • 連続実行モード対応
