🎓 Lesson 14-7: Parallel Execution and Finishing - Multi-Article Batch Processing

📍 What You'll Do

Welcome to **Lesson 14-7: Parallel Execution and Finishing - Multi-Article Batch Processing**!

| Item | Details | |------|---------| | Goal | Learn how to generate articles in parallel across multiple themes and run the entire pipeline in batch | | Duration | ~40 min | | Skills Used | article-writer, style-analyzer, proofreading-agent, fact-checker, nanobanana, diagram-generator | | Prerequisites | Lessons 14-1 through 14-6 complete (understanding of all stages) | | Course Page | Refer to [Module 14: Article Writing](https://ai-agent.camp/en/course/module-14) in parallel |

**Session flow:** 1. Set up multiple themes 2. Demonstrate parallel article generation using the Task tool 3. Run proofreading and fact-checking in parallel for each article 4. Final review and output of all articles

By the end of this session, articles across multiple themes will be completed in parallel, and you will have mastered the batch execution pattern for the entire pipeline.

> **💡 Hint**: If the AI response stops midway, type "please continue" or "it stopped" to resume. Responses may pause depending on the tool, but this is not a malfunction.

🎯 Readiness Check

First, let's confirm everything is ready.

**AskQuestion settings:**

{
  "title": "🎯 Pre-Session Check",
  "questions": [{
    "id": "readiness",
    "prompt": "Are you ready?",
    "options": [
      {"id": "ready", "label": "Ready! Let's start"},
      {"id": "check_prereq", "label": "I want to check the prerequisites"},
      {"id": "view_html", "label": "I want to see the course page first"},
      {"id": "different_lesson", "label": "I want to go to a different lesson"}
    ]
  }]
}

(ready → Proceed to Step 1) (check_prereq → Run prerequisite check) (view_html → Show course page path) (different_lesson → Display module list)

🚀 Step 1: Set Up Multiple Themes

In Codex, you typically select from choices in chat to choose the number of themes.

**AskQuestion settings example:**

{
  "title": "🚀 Step 1: Choose Number of Themes",
  "questions": [{
    "id": "theme_count",
    "prompt": "Select the number of themes for parallel generation",
    "options": [
      {"id": "two", "label": "2 themes (beginner-friendly, shorter processing time)"},
      {"id": "three", "label": "3 themes (standard, experience the effect of parallel processing)"},
      {"id": "custom", "label": "Specify themes yourself"}
    ]
  }]
}

**If "2 themes":** Input:

We will generate articles in parallel for the following 2 themes.

Theme A: "5 Tips to Boost Remote Work Productivity"
- Target: Business professionals working from home
- Article type: Blog post
- Estimated word count: 2500-3000 characters

Theme B: "Skills Required in the AI Era"
- Target: People in their 20s-30s considering career advancement
- Article type: Explainer article
- Estimated word count: 3000-3500 characters

Save each theme's outline to output/batch/theme-a-outline.md and theme-b-outline.md.

**If "3 themes":**

We will generate articles in parallel for the following 3 themes.

Theme A: "5 Tips to Boost Remote Work Productivity"
Theme B: "Skills Required in the AI Era"
Theme C: "Communication Techniques to Improve Team Efficiency"

Save each theme's outline to output/batch/.

**Expected result**: Outlines for multiple themes are generated in output/batch/.

🚀 Step 2: Parallel Article Generation Using the Task Tool

In Codex, you typically select from choices in chat: "Continue / Review examples / Skip".

**AskQuestion settings example:**

{
  "title": "🚀 Step 2: Run Parallel Article Generation",
  "questions": [{
    "id": "step_action",
    "prompt": "What would you like to do with this step?",
    "options": [
      {"id": "practice", "label": "Continue"},
      {"id": "review", "label": "Just review examples"},
      {"id": "skip", "label": "Skip"}
    ]
  }]
}

**Post-selection instructions (example)**: Input:

Use the Task tool to generate articles for multiple themes in parallel.

Run the following stages in parallel for each theme:
1. Outline → draft generation (article-writer + style-analyzer)
2. Illustration marker detection and image generation (nanobanana / diagram-generator)
3. Image embedding

Parallel execution pattern:
- Task 1: Theme A article generation (output/batch/theme-a-draft.md)
- Task 2: Theme B article generation (output/batch/theme-b-draft.md)
(Add Task 3 for 3 themes)

Use the shared style profile output/style_profile.yaml for all themes.
Save all results to output/batch/ after all tasks complete.

**Expected result**: Article drafts for multiple themes are generated in parallel, with processing time shorter than sequential execution.

🚀 Step 3: Parallel Proofreading and Fact-Checking

In Codex, you typically select from choices in chat: "Continue / Review examples / Skip".

**AskQuestion settings example:**

{
  "title": "🚀 Step 3: Run Parallel Proofreading and Fact-Checking",
  "questions": [{
    "id": "step_action",
    "prompt": "What would you like to do with this step?",
    "options": [
      {"id": "practice", "label": "Continue"},
      {"id": "review", "label": "Just review examples"},
      {"id": "skip", "label": "Skip"}
    ]
  }]
}

**Post-selection instructions (example)**: Input:

Run proofreading and fact-checking in parallel for each article.

Parallel execution pattern:
- Task 1: Theme A proofreading (proofreading-agent)
- Task 2: Theme B proofreading (proofreading-agent)
- Task 3: Theme A fact
