Update Blog Links After Publish

Purpose: Record published article in project plan

Action: Add new row to "公開済み記事" (Published Articles) table

Format:

| Phase {number} | {title} | {date} | {tag} | {url} |

Example:

| Phase 6b | 複雑な形状を描画する | 2026-01-03 | v6b.0 | https://an-embedded-engineer.hateblo.jp/entry/2026/01/03/... |

Location: Add to the table under the "公開済み記事" section

2. blog/phase{previous_number}.md

Purpose: Update "Next" link in previous article

Action: Replace the "次回" (Next) section at the end of the file

Before:

**次回**: 第N+1回「{title}」(準備中)

After:

**次回**: [第N+1回「{title}」]({url})

Example:

**次回**: [第7回「複雑な形状を描画する」](https://an-embedded-engineer.hateblo.jp/entry/2026/01/03/...)

Note: Find the previous phase number by looking at the current phase (e.g., if current is 6b, previous is 6a)

3. blog/phase{current_number}.md

Purpose: Final check of current article

Action: Verify and adjust if needed:

• Image paths converted to Hatena format ([f:id:...])
• Previous/next links are correct
• Any minor formatting adjustments

Usually: No changes needed if already published

4. blog/phase0_introduction.md

Purpose: Update series index (table of contents)

Action: Add new row to published articles table

Format:

| [第N回 {title}]({url}) | Phase {number} | {date} |

Example:

| [第7回 複雑な形状を描画する](https://an-embedded-engineer.hateblo.jp/entry/2026/01/03/...) | Phase 6b | 2026-01-03 |

Location: Add to the table in chronological order

Execution Workflow

Step 9-1: Create Update Plan

Copilot should:

1. Confirm received information (phase number, title, URL, date, tag)
2. Show specific changes for each of 4 files
3. Provide diff preview for each change

Example output:

## Link Update Plan

**Phase**: 6b
**Title**: 複雑な形状を描画する
**URL**: https://an-embedded-engineer.hateblo.jp/entry/2026/01/03/...
**Date**: 2026-01-03
**Tag**: v6b.0

### Changes:

1. plan/blog_phases.md
   - Add: | Phase 6b | 複雑な形状を描画する | 2026-01-03 | v6b.0 | {url} |

2. blog/phase6a.md
   - Update: Next link to Phase 6b

3. blog/phase6b.md
   - Verify: Images and links

4. blog/phase0_introduction.md
   - Add: | [第7回 複雑な形状を描画する]({url}) | Phase 6b | 2026-01-03 |

Step 9-2: Apply Changes

Copilot should:

1. Use multi_replace_string_in_file for efficient batch updates
2. Update all 4 files
3. Show confirmation of each change

Recommended approach:

multi_replace_string_in_file with 3-4 replacements covering:
- plan/blog_phases.md
- blog/phase{previous}.md
- blog/phase0_introduction.md

Step 9-3: User Verification & Commit

User should:

1. Review changes with git diff
2. Verify URLs are correct
3. Commit changes

git add -A
git commit -m "docs: Phase {number} - リンク更新（記事公開）"
git push origin phase{number}/{keyword}

Important Notes

• Accuracy: Double-check phase numbers and URLs
• Git Diff: Always recommend user verify with git diff before committing
• Formatting: Maintain consistent table formatting (alignment, spacing)
• Previous Phase: Calculate correctly (6b → previous is 6a, 7a → previous is 6b)

Example Usage

User: "Phase 6b article published. URL: https://an-embedded-engineer.hateblo.jp/entry/2026/01/03/123456"

Copilot should:

1. Extract phase number (6b)
2. Ask for missing info (title, date) if not in context
3. Execute 9-1: Show update plan
4. Execute 9-2: Apply changes to 4 files
5. Execute 9-3: Remind user to verify and commit
