spec-workflow-init — Development Workflow Generator

Generate a project-specific issue-to-pr-workflow.md through interactive dialogue. The workflow serves as a playbook for spec-implement and development agents.

Language Rules

1. Auto-detect input language → output in the same language
2. Japanese input → Japanese output, use references/workflow-template.ja.md
3. English input → English output, use references/workflow-template.md
4. Explicit override takes priority (e.g., "in English", "日本語で")

Sub-agent template selection (when generating agent definitions):

• English → references/agents/claude/workflow-*.md
• Japanese → references/agents/claude/workflow-*.ja.md
• Codex templates: English → references/agents/codex/workflow-*.toml, Japanese → references/agents/codex/workflow-*.ja.toml

Execution Flow

Step 1: Initial Checks

1. Verify Git repository:

   git rev-parse --is-inside-work-tree 2>/dev/null
   

   If not a Git repo, warn and skip branch detection. Continue with other checks.

2. Check current directory:

   pwd
   ls -la
   

3. Detect existing workflow file:

   find . -name "issue-to-pr-workflow.md" -maxdepth 3 2>/dev/null
   

   If found and --force is not set, show the existing file path and proceed to Step 7 (idempotency handling).

Step 2: Environment Detection

Run the following checks to auto-detect the project environment:

Package manager:

ls pnpm-lock.yaml yarn.lock package-lock.json bun.lockb 2>/dev/null

Container usage:

ls docker-compose.yml docker-compose.yaml Dockerfile 2>/dev/null

CI/CD service:

ls -d .github/workflows .gitlab-ci.yml .circleci 2>/dev/null

Branch information:

git branch -r 2>/dev/null | head -10

Language, framework, and scripts:

cat package.json 2>/dev/null | grep -A 50 '"scripts"'
cat package.json 2>/dev/null | grep -A 30 '"dependencies"'
ls go.mod requirements.txt pyproject.toml 2>/dev/null

Database:

ls prisma/schema.prisma 2>/dev/null
grep -l "postgres\|mysql\|mongo" docker-compose.yml 2>/dev/null

Lint tools:

ls .eslintrc* biome.json 2>/dev/null

Coding rules file:

find . -name "coding-rules.md" -maxdepth 3 2>/dev/null

Present the detection results to the user in a summary table:

Detected project environment:
  Language/FW:       {detected}
  Package Manager:   {detected}
  Container:         {detected}
  Test:              {detected}
  CI/CD:             {detected}
  Branch:            {detected}
  Database:          {detected}
  Lint:              {detected}
  Coding Rules:      {detected or "Not found"}

Ask the user to confirm or correct the detection results before proceeding.

Step 3: Interactive Dialogue

Gather workflow configuration through AskUserQuestion rounds.

Round 1: Output Path

question: "Where to save issue-to-pr-workflow.md?" / "issue-to-pr-workflow.md の出力先は？"
header: "Output"
options:
  - "docs/issue-to-pr-workflow.md (Recommended)" / "docs ディレクトリ直下（推奨）"
  - "docs/development/issue-to-pr-workflow.md" / "docs/development 配下"

Round 2: Branch Strategy

Q1:
question: "Base branch (PR target)?" / "ベースブランチ（PRターゲット）は？"
header: "Branch"
options:
  - "develop (Recommended)" / "feature → develop → main（Git Flow）"
  - "main" / "feature → main（GitHub Flow）"
  - "trunk" / "Short-lived branches → main（Trunk-based）"

Q2:
question: "Feature branch naming convention?" / "featureブランチの命名規則は？"
header: "Naming"
options:
  - "feature/{issue}-{slug} (Recommended)" / "e.g. feature/42-add-auth"
  - "{issue}-{slug}" / "e.g. 42-add-auth"
  - "{type}/{issue}-{slug}" / "e.g. fix/42-login-bug, feat/43-dashboard"

Round 3: Quality Gates

question: "Quality gates before PR creation?" / "PR作成前の品質ゲートは？"
header: "Gates"
multiSelect: true
options:
  - "All tests must pass (Recommended)" / "テスト全パス（推奨）"
  - "Lint and type check must pass" / "Lint / Typecheckパス"
  - "Coverage threshold" / "カバレッジ基準"

Round 4: Development Style

question: "Select your development style" / "開発スタイルを選択してください"
header: "Style"
options:
  - "Implementation First (Recommended)" / "実装 → レビュー → テスト → テストレビュー → 品質ゲート → PR"
  - "TDD" / "テスト(RED) → 実装(GREEN) → リファクタ → レビュー → 品質ゲート → PR"
  - "BDD" / "E2Eシナリオ → テスト(RED) → 実装(GREEN) → レビュー → 品質ゲート → PR"

Round 5: E2E Test Level

question: "E2E test scope?" / "E2Eテストの範囲は？"
header: "E2E"
options:
  - "API level only (Recommended)" / "supertest等でリクエスト→レスポンスを検証"
  - "API + Browser E2E" / "上記 + Playwrightでクリティカルパスを検証"

Round 6: Parallel Execution

question: "Use parallel execution for implementation and tests?" / "実装とテストの並列実行を使いますか？"
header: "Parallel"
options:
  - "Sequential (Recommended)" / "メインエージェントが全工程を順番に実行（安全・シンプル）"
  - "Parallel" / "実装とテストコード生成を並行して実行（高速・要エージェント分離）"

Round 7: Agent Targets (only if Parallel selected)

Ask which agent definitions to generate. Do NOT decide targets based on .claude/ / .codex/ directory detection.

question: "Which agent definitions should be generated?" / "どのエージェント定義を生成しますか？"
header: "Agents"
options:
  - "Both Claude + Codex (Recommended)" / "Claude と Codex の両方を生成"
  - "Claude only" / "Claude のみ生成"
  - "Codex only" / "Codex のみ生成"
  - "Skip generation" / "生成しない"

Additional Questions (project-type specific):

• Docker project: "Run all commands inside Docker?" / "Docker内で全コマンドを実行しますか？"
• Next.js project: "Include build check in workflow?" / "ビルド確認をワークフローに含めますか？"

Step 4: Workflow Generation

1. Select template based on Language Rules:

   • English → references/workflow-template.md
   • Japanese → references/workflow-template.ja.md

2. Read the template and replace placeholders with collected values:

   • {package_manager}, {container_tool}, {database}, {test_framework}, etc.
   • {pr_target}, {branch_naming}, {dev_style}
   • {test_command}, {lint_command}, {typecheck_command}, {build_command}
   • {e2e_test_command}, {browser_e2e_command}, {coverage_command}
   • {timestamp} → current date/time

3. Select development style sections:

   • Implementation First → keep {if_implementation_first}...{end_implementation_first}, remove TDD/BDD blocks
   • TDD → keep {if_tdd}...{end_tdd}, remove others
   • BDD → keep {if_bdd}...{end_bdd}, remove others

4. Handle conditional sections:

   • Browser E2E not selected → remove {if_browser_e2e}...{end_browser_e2e} blocks
   • Parallel not selected → remove {if_parallel}...{end_parallel} blocks
   • If agent targets include Claude → keep {if_claude_agents}...{end_claude_agents}, otherwise remove
   • If agent targets include Codex → keep {if_codex_agents}...{end_codex_agents}, otherwise remove
   • If agent generation is skipped → keep {if_no_agent_files}...{end_no_agent_files}, otherwise remove
   • No typecheck command → remove {if_typecheck}...{end_typecheck}
   • No build command → remove {if_build}...{end_build}

5. Clean up remaining placeholders and conditional markers

6. Create output directory if needed:

   mkdir -p {output_directory}
   

7. Write the file to the specified output path

Step 5: Idempotency Handling

If an existing workflow file is detected (from Step 1 or during generation):

1. Without --force: Show a warning with the existing file path

   question: "Existing workflow found at {path}. Overwrite?" / "既存のワークフローが {path} に見つかりました。上書きしますか？"
   header: "Overwrite"
   options:
     - "Yes, overwrite" / "はい、上書きする"
     - "No, cancel" / "いいえ、キャンセル"
   

2. With --force: Overwrite without confirmation

Step 6: Sub-Agent Generation

Skip this step if the user did not select parallel execution or selected "Skip generation" in Round 7.

Step 6a: Claude Code agents (when Round 7 selection includes Claude):

1. Select template language based on Language Rules:

   • English → references/agents/claude/workflow-*.md
   • Japanese → references/agents/claude/workflow-*.ja.md

2. Read each template and replace placeholders:

   • {coding_rules_path} → detected path (e.g., docs/coding-rules.md)
   • {workflow_path} → output path from Step 3 (e.g., docs/issue-to-pr-workflow.md)
   • {test_command}, {lint_command}, {typecheck_command}, {build_command}
   • {e2e_test_command}, {browser_e2e_command}, {coverage_command}
   • {dev_style} → selected development style
   • {branch_naming} → selected naming convention

3. Create directory and write files:

   mkdir -p .claude/agents
   

   • .claude/agents/workflow-implementer.md
   • .claude/agents/workflow-reviewer.md
   • .claude/agents/workflow-tester.md

4. If files already exist, ask for overwrite confirmation (same as Step 5)

Step 6b: Codex agents (when Round 7 selection includes Codex):

1. Select template language based on Language Rules:

   • English → references/agents/codex/workflow-*.toml
   • Japanese → references/agents/codex/workflow-*.ja.toml

2. Read each TOML template and replace placeholders in developer_instructions:

   • Same variables as Claude Code agents

3. Create directory and write files:

   mkdir -p .codex/agents
   

   • .codex/agents/workflow-implementer.toml
   • .codex/agents/workflow-reviewer.toml
   • .codex/agents/workflow-tester.toml

4. Update .codex/config.toml:

   • Create file if it doesn't exist
   • Add or update agent sections in config.toml:

     [agents.workflow-implementer]
     config_file = "agents/workflow-implementer.toml"
     
     [agents.workflow-reviewer]
     config_file = "agents/workflow-reviewer.toml"
     
     [agents.workflow-tester]
     config_file = "agents/workflow-tester.toml"
     

   • Add [features] multi_agent = true if not present

5. If files already exist, ask for overwrite confirmation

Step 7: AGENTS.md / CLAUDE.md Reference Update

1. Check for convention files:

   ls AGENTS.md CLAUDE.md 2>/dev/null
   

2. If CLAUDE.md is a symlink to AGENTS.md, update only AGENTS.md:

   readlink CLAUDE.md 2>/dev/null
   

3. If at least one file exists, ask for confirmation:

   question: "Add workflow reference to AGENTS.md / CLAUDE.md?" / "AGENTS.md / CLAUDE.md にワークフローの参照を追記しますか？"
   header: "Update"
   options:
     - "Yes, add reference (Recommended)" / "はい、参照を追記する（推奨）"
     - "No, skip" / "いいえ、スキップ"
   

4. If approved, append the following section (adapt language to match output):

   English:

   ## Development Workflow
   
   Follow the development workflow for Issue → Implementation → PR:
   - [{workflow_path}]({workflow_path}) — Development workflow generated by spec-workflow-init
   

   Japanese:

   ## Development Workflow
   
   開発フロー（Issue → 実装 → PR）は以下のファイルに従ってください:
   - [{workflow_path}]({workflow_path}) — spec-workflow-init で生成された開発ワークフロー
   

5. If neither file exists, output a warning:

   "Warning: Neither AGENTS.md nor CLAUDE.md found. Skipping reference update."
   / "警告: AGENTS.md も CLAUDE.md も見つかりません。参照追記をスキップします。"
